Learning and ethology;
the psychological study of learning and research concerning the way in which animals and people learn.
Historical perspective; Edward Thorndike, first to study____; part of this psychological system, define.
1874-1949; One of the early psychologists who studied learning; functionalist school, focusing on how the mind functioned in adapting to the environment.
Thorndike along with functionalism, he is also considered to be an early; reflected in his study of this type of behavior____of______.Result of his study developed the ______, which formed the basis for________.
Behaviorist; objective behavior of animals; law of effect; operant conditioning.
One of the original experiments on learning that founded____ in ________by _____.
Classical conditioning experiment; behaviorist system of thought;1920, John Watson
Little albert; wasnt afraid of laboratory rats until Watson made a loud noise behind Alberts head when presented w/rat; results and outcome
Learned to associate the white rat w/loud noise; began to show fear response and then associated that response to a rabbit, and mink coat
Ivan Pavlov
Classical conditioning.
After Watson, behaviorism became this in the system of psychology in the U.S. until about 1960.
Dominant psychological school/system
Clark Hull's theory of motivation also known as this theory____; stated that goal of behavior was to_____; when the goal for behavior is met this takes place.
Drive-reducation theory; the goal of behavior is to reduce biological drives; when bio drive is reduced, reinforcement occurs.
In the 1930's due to the work of Konrad Lorenz, this marked the beginning of _____ as a recognized discipline; Lorenz rejected this idea of behaviorists in favor of these methods.
Rejected the idea that animal behavior could be understood in the laboratory, contrary to the behaviorist methodology; Lorenz believed that an understanding of animal behavior could be gained only out in the field.
What type of reserch methods did Lorenz impliment vs. Watson; Lorenz used these methods to observe and report behavior of animals.
Field research or naturalistic observation of animal in its personal environment, he was able to describe the animal's behavior in great detail, qualitative; Watson experimental, quantitative;
Lorenz by studying the context in which a particular behavior took place of an animal, he could begin to analyze the _______.
The function that the behavior served; whereas experimental studies do not look so much as function.
Ethologists study animals in this way compared to behaviorists.
In their natural enviroment, rather than in the laboratory.
Classical conditioning also know by this term, is a result of _______; ex.
Respondent condition; result of learning connections between diffrent events; learn that thunder follows lightning, smell of food is floowed by dinner, darkened lights in movie theater mean that the movie is to begin.
Ivan pavlov is credited w/the founding of these______.What discovery did he make and how.
He noticed that through experience, simuli that previously had no relation to a specific reflex could come to trigger that reflex; whie he was studying the reflex of salivation of dogs in response to food.
Reflex and stimulus; Pavlov's dog. The behavior of the dog is____; Specific type of stimulus is required to elicit the UR.
Reflex is san unlearned response that is elicited by a specific stimulus; food powder placed in a dogs mouth the dog reflexively salivates and this is not learned it is reflexive; neutral stimulus;
What happened when Pavlov regularly presented a neutral stimulus, a ringing bell, before putting the food in the dogs mouths? The dogs would also salivate in these situations too.
Initially, the dogs did not react much when they heard the bell ring; after the procedure was repeated several times, the dogs began to salivate then they heard the bell ring; only rang the bell and did not deliver any food.
Classical conditioning, Pavlov's dogs; at what point were the dogs classically conditioned.
When Pavlov only rang the bell and did not give the dogs food, yet the dogs salivated upon hearing the bell.
How did classical conditioning occur in the dogs in response to the originally insignificant stimulus.
The bell ring, became significant for the dogs; they came to realize that once they heard the bell ring, the food would soo be placed in their mouths
Paired, or associated, the neutral stimulus, bell w/food; how was the association made.
The bell ring became paired wplacing the food powder in the dogs mouths; Once this association was made, the dogs began to salivate at the ring of the bell.
Dogs had become through association or pairing;
Conditioned to salivate in response to the bell ring.
UCS/UCR in Pavlo's study
The food which when placed in the mouth results in the salivation of the dog.
UCR/UCS are unconditioned for this reason
These are called unconditioned b/c the animals salivation is the natural response to the stimulus and didnt' need to be conditioned.
Natural responses to a stimulus
These are UCR any thing that is a response to something that would elicit this response and the dogs salivitory response didn't need to be learned (conditioned)
Learned in classical conditioning is associated with this world
Conditioned; any time a response is learned as a result of being associated with a stimulus that makes the response no longer a reflexive behavior to a natural stimulus
After conditioning or learning the new stimulus that elicits the response is called
Conditioned stimulus CS
CR
The animals response to the conditioned stimulus (salivation) this is now the learned response and salivitory response is reflexive learned associate with the CS (bell).
CR/CS called conditioned b/c
The animal had to learn to salivate to the bell.
Classical conditioning key phrases; explanation; phrase, US; UR; CS; CR.
A stimulus that can reflexively elicit a response; a response reflexively elicited by an US; stimulus that, after conditiong, is able to elicit a nonreflexive response; Response that, after condition, is elicited by a conditioned stimulus.
Critical factor in success of classical conditioning is this; what is the procedure;
Timing of CS and UCS; Pavlov's experiement the CS bell ring presented before the UCS food;
Forward conditioning
For clasical conditioning to work, the CS has to be presented before the UCS; CS bell, UCS food.
Acquisition
Term used to describe the period during which an organism is learning the association of the stimuli; conditioning period of pairing the CS with UCS, by presenting CS before UCS; to elicit a CR.
Extinction; give example of this process
Once classical conditioning occurs, it can be unlearned through a process; Repeatedly present the CS w/o the UCS; ring the bell, but not give the dog any food power; do this over and over again the dog will eventually stop salivating in response to bell ring.
Spntaneous recovery; when does this behavior occur in the classical conditioning model; what kind of a response will be elicited by the CS.
After extinction occurs, the CS (bell ring) can once again elicit the CR of salivation; After a period of rest, presenting the bell (CS) w/o the food (UCS), will elicit a weak CR of salivation.
During spontaneous recovery the CS can elicit a weak CR w/o the UCS present; if further extinction training is implemented what is the outcome.
Further extinction training will once again cause the animal to stop salivating (CR) to the bell ring (CS).
Generalization; example; evidence of this behavior in children.
Tendency for stimuli similar to CS to elicit the CR; dogs may have eventually salivated to bells of a different pitch and/or timbre; child is bitten by large dog, may fear all dogs.
Classical conditioning key concepts; explanation; concept, forward/back conditioning, extinction, spontaneous recovery, generalization.
Presenting the UCS following the CS; Presenting the CS following the UCS; generally unsuccessful; Repeatedly presenting the CS w/o the UCS; after extinction and a period of rest, presenting the CS w/o the UCS will again elicit a weak CR; after conditioning, the tendency for stimuli similar to the original CS to elicit the CR
Classical conditioning has limited usefulness for _____; why? what other classsical conditioning phonomena become more effective?
Humans; in classical conditioning learning stimmuli are paired only when one of the stimuli (the UCS) elicits a reflex; humans have few reflexes; Second-order conditioning and sensory preconditiong expand the usefulness/applicability of classical conditioning in humans.
Second order conditioning; name two stages;
A NS is paired with a CS rather than an UCS; Stage 1 is regular classical conditioning; Stage 2 presentation of a new UCS (flash of light) stimulus just before presenting the CS (bell ring) w/o the (CR) present.
Pairing of NS with CS; regular classical conditioning; new UCS just before presenting the CS; give example; third order conditioning.
Stage 1 is conditioning dog to salivate to a bell ring; NS/CS; Stage 2, UCS flash of light, prior to the CS bell ring, w/o the food powder (CR), dog will salivate to the light flash alone; tick of a metronome followed by light flash; salivate to metronome.
Sensory preconditioning; 2 stages; NS is____;describe process
Two NS are paired together and then one of the NS is paired w/UCS; Stage 1, pair 2 NS, flash of light and bell, not natural elicitors of UCR; Stage 2, pair the bell (NS) w/UCS ,(food); after animal salivates CR to bell alone, then test for the effect of sensory preconditioning by flash light w/o either ring bell or present food.
Acquisition
Term used to describe the period during which an organism is learning the association of the stimuli; conditioning period of pairing the CS with UCS, by presenting CS before UCS; to elicit a CR.

Tendency for stimuli similar to CS to elicit the CR; dogs may have eventually salivated to bells of a different pitch and/or timbre; child is bitten by large dog, may fear all dogs.
Classical conditioning key concepts; explanation; concept, forward/back conditioning, extinction, spontaneous recovery, generalization.
Presenting the UCS following the CS; Presenting the CS following the UCS; generally unsuccessful; Repeatedly presenting the CS w/o the UCS; after extinction and a period of rest, presenting the CS w/o the UCS will again elicit a weak CR; after conditioning, the tendency for stimuli similar to the original CS to elicit the CR
Classical conditioning has limited usefulness for _____; why? what other classsical conditioning phonomena become more effective?
Humans; in classical conditioning learning stimmuli are paired only when one of the stimuli (the UCS) elicits a reflex; humans have few reflexes; Second-order conditioning and sensory preconditiong expand the usefulness/applicability of classical conditioning in humans.
Second order conditioning; name two stages;
A NS is paired with a CS rather than an UCS; Stage 1 is regular classical conditioning; Stage 2 presentation of a new UCS (flash of light) stimulus just before presenting the CS (bell ring) w/o the (CR) present.
Pairing of NS with CS; regular classical conditioning; new UCS just before presenting the CS; give example; third order conditioning.
Stage 1 is conditioning dog to salivate to a bell ring; NS/CS; Stage 2, UCS flash of light, prior to the CS bell ring, w/o the food powder (CR), dog will salivate to the light flash alone; tick of a metronome followed by light flash; salivate to metronome.
Sensory preconditioning; 2 stages; NS is____;describe process
Two NS are paired together and then one of the NS is paired w/UCS; Stage 1, pair 2 NS, flash of light and bell, not natural elicitors of UCR; Stage 2, pair the bell (NS) w/UCS ,(food); after animal salivates CR to bell alone, then test for the effect of sensory preconditioning by flash light w/o either ring bell or present food.
In stage 2, after the animal salivates to the bell alone and testing for the effect of sensory preconditioning by flashing light w/o either ring of bell or presenting food, what is the outcome?
Sensory preconditioning took place b/c that even though the light flash and the food were never directly paired, the light flash elicits salivation; never pair one of the NS w/UCS to elicity the CR.
Second order conditioning vs sensory preconditioning; Type; stage 1 stimuli; stage 2 stimuli; Stimuli present during testing stage.
1) CS, bell; UCS, food; 2) NS, light flash; CS, bell ring; NS, light flash; Sensory-pre, 1) NS1, light flash; NS2, bell ring; 2) NS2, bell ring (becomes CS), UCS, food; NS1, food and light flash.
Temporal contiguity; until late 60's, psychologists believed that CConditioning occurred for this reason
Because the CS and the UCS were presented in succession; temporal contiguity of the CS and UCS were essential to the conditioning.
Robert Rescorla suggested that classical conditioning was a result of this process.
CC was a matter of learning signals for the UCS to the extent that the CS is a good signal and that it has informational value or is a good predictor of the UCS.
Contingency explanation of classical conditioning
Robert Rescorla; CS must have a good signal and be a good predictory of the UCS, the CS and UCS will become associated and classical conditioning will occur.
Blocking procedure; other researchers have been critical of Rescoral's contingency explanation of CC;
Rescorla's explanation didn't go far enough; Not only must the CS and UCS be continget (good signal, info value and predictor); the CS must also provide nonredundant info about the occurrence of the UCS in order for conditioning to occur; this relevant experimental procedure is called blocking.
Original blocking experiment had 2 stages. In first stage this occurred; after repeated trials, this was the result; stage 2 what is presented; what is the outcome.
Stage 1, rats heard a hissing noise (CS) and were then given an electrical shock (UCS); rats began to show fear of the (CS) alone w/o the shock; In stage 2, the (CS) hissing and light presented at the same time, followed by the UCS; after several trials there were 2 CS (hissing, light).
If classical conditioning were based on contingency alone, the this would be the outcome; light is a good predictor of this stimulus as this CS, which rats showed CR of fear when presented. What is the expected outcome when the CS light is presented.
The rat would show a fear (CR) response to the light (CS); Light good predictor of the UCS as the CS, rats showed CR of fear w/CS; would expect the light to become associated w/the shock (CS) and would expect the rat to show a fear response to (CS) light.
When the CS, light was presented alone, the rat_____, providing evidence that the rats_____why, what was the hissing noise (CS)?
Did not show a fear response, light did not elicit a CR; did not learn the association btw the light and the shock; b/c the rat learned in stage 1 that the hissing noise (CS) was a good predictor of the shock.
In stage 2 of the contiguity experiment why did the light not elicit the CR; for classical conditioning to occur it is not enough for this to take place
Stage 2, the light provided no additional info useful for the rat in predicting when shock will occur, so the rat used the info of the hissing noise (CS) to predict when the shock would occur; CS and the UCS to be contingent; the CS must also provide seful, that is nonredundant, information about the occurrence of the UCS.
Classical conditioning; explanations that have been proposed for why it works; explanation; concept, contiguity, contingency, blocking.
CS and UCS are contiguous (near) in time; CS is a good signal for UCS; CS is a good signal for UCS and provides nonredundant info about the occurrenece of the UCS.
Operant conditioning also known by this term; based on learning the relationship btw these variables; use this conditioning when and is controlled by this outcome
instrumental conditioning or reward learning; relationship btw one's actions and their consequences; use operant conditiong principles in every day life; consequences
Pioneers of operant conditioning; date; theory.
E.L. Thorndike; 20th C.; law of effect which states if a response is followed by an annoying consequence, the animal will be less likely to emit the same response in the future.
BF Skinner agreed w/Thorndike's contention; but rejeted Thorndike's stress on these, name; Skinner further develped the study of operant conditioning, distinguishing four important concepts:
That envrionmental consequences affect the probability of response; mentalistic terms, satisfying and annoying; pos/neg reinforcement, punishment, extinction.
Skinner's positive reinforcement in operant condition.
The probability that the desired response will be performed is increased by giving the organism something it wants (reward) whenever it makes the desired response
Positive reinforcement as reward for a desired response; ex.
Reward a person in order to increase the frequency of a particular behavior; give a god a biscuit (reward), every time he comes when he is called, dog will learn to respond in order to get the reward (treat).
Negative reinforcement
The probability that the desired response will be perfored is increased by taking away or preventing something undesirable whenever the desired response is made.
Negative reinforcers can be ___once the desired response has been achieved; two types of neg. reinforcement
Turned off; escape and avoidance;
Negative reinforcements, escape, role in operant conditioning to increase a desired behavioral response.
Escape, the behavior removes omething undesireable; loud annoying buzzer, reminding me that my seatbelt is not fastened, can be taken away (escaped from ) by fastening my seat belt
Negative reinforcements, avoidance, role in operant conditioning to increase a desired behavioral response.
organism gets a warning that an aversive stimulus will soon occur, and the appropriate response completely avoids the aversive stimulus; ex. heeding the warning inherent in a stop sign: if I stop first before entering the intersection, I was likely to Avoid a crash; through avoidance, my behavior stops an aversive stimulus from ever happening.
In reinforcement, whether pos/neg, behavior is being affected which means that
It is more likely that I will, in the future, perform the same behavior under similar circumstances.
In punishment
The probability that a response will be made is decreased by giving the organism something undesirable whenever the response is made; ex. sending a child to his room for writing on wall, decreases the probability that the behavior will not occur again.
Stimulus in punishment; stimulus in neg. reinforcement.
When the stimulus is applied it is punishment; when the stimulus is removed it is neg. reinforcement.
Distinguish btw goal of punishment vs. negative reinforcement
Punishment is to decrease the probability of a particular behavior; Negative reinforcement is to increase the probability of a particular behavior.
According to Skinner we don't know if something is a reinforcer or a punisher until we look at the effect it has on the behavior.
Ex. child reprimanded for clowning around in clas, is the child's behavior being reinforced or punsihed; it depend on whether or not the childs clowning around increased in frequency or decreased in frequency; child clown around more after the reprimand, then the reprimand is a reinforcer, child may like the attention from the reprimand.
In reinforcement, whether pos/neg, behavior is being affected which means that
It is more likely that I will, in the future, perform the same behavior under similar circumstances.
In punishment
The probability that a response will be made is decreased by giving the organism something undesirable whenever the response is made; ex. sending a child to his room for writing on wall, decreases the probability that the behavior will not occur again.
Stimulus in punishment; stimulus in neg. reinforcement.
When the stimulus is applied it is punishment; when the stimulus is removed it is neg. reinforcement.
Distinguish btw goal of punishment vs. negative reinforcement
Punishment is to decrease the probability of a particular behavior; Negative reinforcement is to increase the probability of a particular behavior.
According to Skinner we don't know if something is a reinforcer or a punisher until we look at the effect it has on the behavior.
Ex. child reprimanded for clowning around in clas, is the child's behavior being reinforced or punsihed; it depend on whether or not the childs clowning around increased in frequency or decreased in frequency; child clown around more after the reprimand, then the reprimand is a reinforcer, child may like the attention from the reprimand.
Operant condtioning basic types; characteristic; effect on probability of response; type, pos. reinforcement/neg. escape, avoidance, punishment, extinction.
Behavior is rewarded increases probability; behavior removes something undesirable, increases probability; behavior avoid something undesirable, increases probability; behavior causes something undesirable, decreases probability; behavior that used to bring reward no longer does so, decreases probability.
discriminative stimulus
A stimulus condition that indicates that the organism's behavior will have consequences
A pigeon pecks at a key to get a food pellet. The food pellet fuctions_____.
Functions as a positive reinforcement, increasing the pigion's pecking behavior.
A light sets above the key; when the pigeon pecks at the key a pellet will be available if the light is on, but if the light is off, the pigeon will not get a pellet for pecking at the key, what is the SD.
Pigeon's action reinforced only when the light is on. The SD, discriminative stimulus is the illuminated light.
Generalization, classical conditioning concept; if the SD is a colored light what happens in generalization.
Train an animal to peck for food when a green light is on (SD); after training the animal will peck not only when the gree light is on, but also when similar colored lights are on; closer the colr of the light is to green, the more likely it is that the animal will peck; generalization is extremely important concept of learning.
Partial reinforcement effect; extinction; what human behavior is indicitive of this effect.
Train rat A pellet every time lever is pressed and rat B only occassionaly then it will take longer for rat B to make the lever pressing extinct; gambling, behavior is reinforced by an occasional win.
Four basic types of partial reinforcement called; name
Schedules of reinforcement; fixed ratio (FR), variable ratio (VR), fixed interval (FI), variable interval (VI).
Fixed-ration (FR).
The organism receives reinforcement only after a fixed number of responses; after every five lever presses, receive food.
Variable ratio (VR).
The animal receives reinforcement after a varying number of responses; VR5 schedule, animal will receive, aon average a food pellet for every five lever presses;on any particular trial the food pellet could come on the second lever press, or the fifth lever press, or the 17th lever press
Fixed interval (FI)
Animal will be reinforced on the first response after a fixed period of time has elapsed since the last reinforcement; an FI 45 second schedule wil receive the food pellet for the first lever press after 45 seconds have elapsed since the last reinforcement.
VI
The animal will be reinforced for the first response made after a variable amount of time has elapsed since the last reinforcer; there is an average time interval period.
What is the term called for an animal that is being reinforce for every response.
FR1 or continuous reinforcement schedule CRF
Examples of reinforcement schedules in real life; FR schedule in the work place; VR schedule
Worker receives money for every 1000 envelopes stuffed; Slot machine, dropping a coin in a slot machine will be reinforce by winning every so often.
Examples of reinforcement VI
A parent responding to a crying child; From child's perspective, the response of interes is the crying and the reinforcement is the parent responging to the child; doesnt go back in after the child cries waits a while so certain time interval has to pass before the child will be reinforce for crying. exactly wat that time interval is will vary depending on the situation.
Which schedule most resistant to extinction; nmeunonic, to remember this; which produces the most rapid response rate out of the four basic schedules.
VR is resistant to extinction; VR very resistant; VR also produces the most rapic response rate; VR can also stands for very rapid response rate.
Shaping; teaching dog to fetch slippers example.
REinforce successive approximations to the desired behavior; reinforce every time your dog looks at the slippers; after the dog is doing that consistently, you would stop reinforcing her for just looking at the sliiper, and reinforce her only when she wals toward your slippers; once that is consitent then reinforce for only picking up slippers.
Differential reinforcement
Reinforcing desired response while extinguishing others; shaping is sometimes called this.
Successive approximations
In shaping this is what is being reinforce each time the animal or person gets closer to the desired behavior.
Behavior therapies; behavior modification; tx in psychpathologies
conditioning is relevant in life, but especially relevant and for therapeutic tx; we can divide behavior therapies into 2 groups; those based on classical conditiong and those based on operant conditioning.
Therapies based on classical are used for what clinical conditions; what is an explanation for a phobia, how do they develop at times.
Phobias and also with OCD; Phobia is an irrational fear; They develop through classical conditioning, out of a learned association btw an aversive US and a CS
With phobias what is the best way to get rid the phobias w/classical conditioning; what classical conditioning process
Through extinction; by repeatedly presenting the feared object, the CS w/o the associated US that originally elicited the fear, the fear response to the CS will decrease and will eventually be eliminated.
Is this easy to treat phobia's w/extinction? Take for instance a fear of cats?
No b/c the fear is irrations; if the person is exposed to cats several times, the person will learn that there is nothing to fear; the rear response wil udergo extinction; therapist has to find a way to expose the client to source of fear.
What is a behavioral therapeutic technique that exposes a client to irrational fears (phobias?).
Flooding; the clien experiences the CS (cat) w/o the US that originally elicited fear; force the client to hold a cat; after the client has the experience of holding the cat as harmless, the person learns that cats don't need to be avoided.
Implosion (behavior therapy), similar to flooding.
The client imagines the fearful situation and dissimilar to flooding, is not exposed to the feared object; by concentrating on the fearful stimulus, where nothing fearful can happen, the person confronts the phobia.
Crticism of both of flooding and implosion.
They force the client to experience a geat deal of anxiety at the beginning of the therapy.
Systematic desensitization, John Wolpe;
This technique reduces the initial up front anxiety by exposure to the feared object; heirarchy of anxiety producing situations coupled w/the use of relaxation techniques; imagine the least anxiety-producing situation in the hierarchy while in a relaxed state.
The principle behind systematic desensitization.
The client cannot experience two contradictory emotions at once; anxiety and relaxation.
Counter-conditioning
The person who is undergoing systematic desensitization, proceeds up the hierarchy until the relatxation responses are reinforce to the anxiety invoking object, stimulus.
Conditioned aversion
Based on classical conditioning; aversion therapy is used when the client is attracted to a behavior that the client and/or the therapist find undersirable.
Conditioned aversion is used for what type of behavioral problems and how does it word.
Alcohol, cigaretts; the stimulus that attarcts the client becomes paired w/an aversive unconditioned stimulus associated w/punishment; negative feelings will be associated to the undesirable behavior and the person will no longer be attracted to the behavior.
Therapies based on operant conditioning attempt to alter the consequences of the client's behavior; explain the goal.
Change the client's behavior by changing the reinforcement contingency that is associated with the behavior; using different kinds of operant conditioning to modify behavior
What is the approach of therapeutic operant conditioning; name the approaches
Contingency management; behavioral contracts, time out procedures, token economies, the premack principle
Behavioral contract; what time of behavior are these contracts aimed to change.
Negotiated agreement btw two parties that explicitly state the behavioral change that is desired and indicates concequences of certain acts; To improve interpersonal situations.
Time-out; goal
Undesirable behavior in situations that reinforce the behavior; remove the client from the reinforcing situation before receiving reinforcement for the behavior; the behavior will not be reinforced and will cease.
Token economies; when are these effective.
Given for desirable behaviors and taken away for various undesireable behaviors; tokens can be exchanged by the client for rewards and privileges; useful in mental hospitals for behaviors like self care, making one's own bed, interacting well w/staff and pts.
Premack principle; give example
A more preferred activity can be used to reinforce a less preferred activity; often applied by parents requiring children to do homework before they can play; using the more preferred activity, playing to reinforce the less preferred activity, studying.
Challenges to behaviorists; who and what theories, underlying principle of the theorists
Points of difference w/other theories/theorists can be shown in the research on problem solving; wolfgang kohler, insight; edward tolman, cognitive map; biological contraints; John Garcia, garcia effect, preparedness
EL Thorndike; law of effect
Conducted a sHeries of experiements to prove that problem solving is bes explained by this law
How did Thornkike test his theories and come up with his law.
Puzzle box;
Puzzle box
Thorndikes experimental design to prove that problem solving is best explained by the law of effect
Design of puzzle box
Is a cage that the animal can open by some simple action, such as presssing a lever; also place a dish of food outside the box.
Getting out of the box the cat does this behavior
The cat tries everything and by chance presses the correct lever to open the door
Once the cat gets out of the puzzle box the first time what happens in subsequent trials.
The cat gets out of the puzzle box at a quicker rate.
Does this demonstrate that the cat has a cognitive understanding or insight into the task of getting out of the box
No, according to Thorndike.
What is the explanation Thorndike gave associated w/ the cats ability to get out of the box at faster intervals w/each trial.
The effect is merely trial and error learning.
The cats behavioral response of pressing the correct level is what, the other behavioral responses not associated with the opening of the door are___.
Reinforced by the food while the other behavioral responses of the cat are not reinforced.
What did thorndike argue related to problem solving.
That all problem solving behaviors were the trial and error type.
Wolfgang Kohler was the cofounder of which school?
Gestalt
Did Kohler agree w/Thorndike that all learning was the trial and error type? Why or why not?
He disagreed w/Thorndike, though he conceded that the animals in Thorndike's experiment learned throught trial and error, he suggested that the animals were forced into trial and error learning b/c of the situation.
Kohler stated that in Thorndikes experiment the cats learning was trial and error b/c they were forced into this type of learning via the situation; however, Kohler argued that if given the opportunity what kind of learning were the cats capable of?
Learning by insight.
Define Kohler's insight learning.
Insight is the perception of the inner relationships btw factors that are essential to solving a problem.
How did Kohler prove insight learning and the capability of animals to engage in this type of learning.
Looked at problem solving in chimpanzees. Placed chimps in enclosed play areas and placed food in their sight but out of reach.
What process did the chimps go through in order to learn by insight.
Would first begin to get the food directly by reaching for it; after that failed they would stop and survey the situation and then suddenly try a different approach
The different approach that the chimps applied to problem solving was based on this__.
Suddenly, they would try a different approach based on a novel way of using items; they would use sticks or climp up on boxes to obtain the food.
Kohler's experiments w/Chimps lead him to conclude___.
The chimps used insight to solve the problem.
What problem does insight learning pose for models of conditioning.
It is difficult to explain insight on the basis of conditioning; insight is an alternative to the simple conditioning model.
Edward Tolman conducted experiments to demonstrate what type of learning.
With rats in mazes, to show that behavior isn't simply a matter of stimulu-response reinforcement learning; cognitive map
Cognitive map
Tolman stated that this is a mental representation of a physical space; able to show that rats were able to for cgnitive maps of various mazes.
How did rats form Cognitive maps according to Tolman
If a familiar path through the maze was blocked the rats were able to utilize their cognitive map to adopt an alternative route.
Biological constraints posed challenges to what kind of theories.
Another challenge posed to behaviorist conditioning and stimulus response theories of learning.
Biological constraints states that__
Different species have different inborn predispositions to learn different things in different ways;
What do biological contraints effect?
Both classical conditioning and operant conditioning.
Garcia effect. Name the theorist and what experiment lead to this effect.
John Garcia. Illustrated in a classical experiement w/thirsty rats.
Describe the experimental design that demonstrated the Garcia effect.
Rats A allowed to lick a tube that relaeases water sweetened; Rats B allowed to lick another tube that releases unsweetened water while simultaneously flashing a light and making a clicking noise.
Two groups of rats, one w/sweetened water, the other unsweetened water, w/flashing light and clicking noise; what happens next in this experiement.
Half A and half B the conditioned stimulus (water) is paired w/ a pain inducing shock; other half of each group, conditioned stimulus is paired w/nausea-inducing drug.
Four groups of rats in the experiment to demonstrate the Garcia effect. Sweet water and Bright noisy water (CS); Shock and nauseating drug (UCS). What is the expected result according to the classical conditioning model.
Classical conditioning should occur in all four groups and all of the groups should demonstrate an aversion to the CS due to bot the shock and the nauseating drug; this is the prediction of classical conditioning.
What conditions demonstrated conditioning effects.
Condition 2, Sweet water (CS) and Nauseating drug (UCS) along w/condition 3, bright noisy water (CS) and Shock (UCS), were the only two groups that conditioning was successful for.
Which groups (conditions) demonstrated the garcia effect.
Condition 1, sweet water (CS) and Shock (UCS) along with Condition 4, bright noisy water (CS) and nauseating drug (UCS), did not show any conditioning;.
Garcia effect was shown in the rates who received this but not this condition.
Rats who received the UCS of nausea inducing drug showed a conditioned aversion to the sweet water but not to the bright noisy water; Rats whe received the UCS of shock showed a conditioned aversion to the bright noisy water but not to the sweet water.
In essence, the Garcia effect is what type of conditioning.
Aversive conditioning or conditioned aversion.
Why does the garcia effect occur or aversive conditioning? And what theory does the garcia effect give support for?
Preparedness; biological constraints and the affect of these upon both classical and operant conditioning.
Preparedness is a term used to explain.
In-born tendence associated w/biological constraints w/in a specific species.
Concerning the rats and the experiemental out come of the garcia affect or aversion conditioning what does preparedness demonstrate? What type of wiring occured in the rats?
Rats seem to have an in-born tendency to associate certain stimuli w/certain consequences; Rates are biologically wired to associate illness w/something they ingested and to pair sights and sound w/externally induced pain.
Thus, conditioning occurred in which groups and not in which groups, for this reason.
Groups 1 & 3 rats were conditioned; and not in 1 & 4 (aversive conditioning took place); due to biological constraints demonstrated through preparedness for ability to be conditioned
In other words, biological constraints and preparedness override??
Conditioning; will not take place over preparedness--animals biological predispositions.
Concerning humans, how does preparedness manifest itself (bio constraints) give ex.
People tend to associate illness w/something they have eaten. Cancer patients this poses a serious issue; they understand that the treatment is making them ill and not the food they eat; biological wiring causes some food aversions regardless of cognitions.
How do researchers overcome biological constraints and preparedness (bio predisposition) in chemo patients; Aversion is developed towards this type of food and not the necessary type of food.
Give patient novel food; like a strange ice cream flavor immediately before tx; this allows for patient to develop an aversion to a food that they typically will not eat outside of the chemo stiuation instead of develping an aversion to a nutritive food.
Taste aversion pose additional problems for classical conditioning name the first
Learned taste aversion can occur after only one trial; one pairing of the CS and UCS. Most of classical conditioning takes many trials of pairing between the CS and UCS for conditioning to fully develop.
Taste aversion pose additional problems for classical conditioning name the second problem this phenomena poses
Subsequent experiemnts on taste aversion learning have shown that such learning can take place evern if the UCS occurs up to 24 hours after the CS;
Taste aversion problem for classical conditioning model related to optimal time for the UCS to be presented after the CS
In typical classical conditioning, optimal time period btw the CS and UCS is several seconds after the presentation of the CS.
So, in the case of taste aversion and the pairing of th UCS up to ___hours later, this creates?
24 hrs after eating a new food, the presentation of the UCS after the CS is presented, will created an aversion (conditioning) to that food.
Biological constraints are also important to demonstrate the limitations of operant conditioning for this reason.
Instincutal drift.
Operant conditioning can affect animals in this way and which theorists demonstrated this.
Operant conditioning can be used to teach animals amazing things; Keller and Marion Breland.
Keller and Marion Breland were what type of psychologists in what years and believed what?
Behavioral psychologists; 1950's' that operant conditioning could be used to train animals to do anything.
Brelands used shaping in animals to implement what type of behavior in what type of experimental design.
Train a raccoon to pick up coins and deposit them into a piggy bank.
How did the Brelands reinforce the racoon to deposit money; what was the response of the racoon.
Reinforce raccoon for picking up the one coin and depsiting into bank; difficult b/c upon picking up coin, raccoon didn't put in bank; would rub coin against container, clutch it and let drop into bank after a long period of hesitation.
Describe the next reinforcement step used by the Brelands in the Raccoon/bank experiment and the behavior of the raccoon after.
Reinforced raccoon for picking up 2 coins at the same time and putting both in the piggy bank was not at all successful; Raccoon picked up 2 coins, rubbed together, dipped in bank and then fully removed.
Instinctual drift and the inability of raccoon to learn through reinforcement to put 2 coins in the bank; describe the behavioral pattern that ensued
Raccoon reverted to a species specific behavioral pattern; raccoons catch crayfish, they instinctively rub the crayfish and dip into water to remove shell, what the raccoon did w/the coins.
Vicarious reinforcement; who and what is the theory.
Albert Bandura; demostrated through the bobo doll experient that behavior could be learn by observation.
Challenges to behviorism; basic concepts; description; Thorndike, Kohler, Tolman
Thorn, behaviorist, problem solving due to trial and error learning; Kohler, Gestalt, Problem solving is insightful; Tolman, Cognitive maps, animals have mental maps of physical spaces
Challenges to behviorism; basic concepts; description; Badura, Garcia, The Bredlands.
Bandura, observational learning, observing others behavior can affect your own behavior; Garcia, preparedness, animals are prepared to learn connections btw certain stimuli; Brelands, instinctual drift; instinctual ways of behaving are able to override behaviors learned through operant conditioning.
Ethology, radically different from which psychological school?
Is the study of animal behavior under natural conditions and is radically different from behaviorism.
The evidence for ethology and the divergence btw ethology and behaviorism hinges on?
Biological constraints on learning.
Thologists concern themselves w/behaviors that are characteristic of a given species; name the term(s) used by ethologists.
Species-specific or species-typical behaviors.
Early ethologists looked at this type of behavior based on a species ____.
Instinctual behavior; instinctual basis from species to species that results in species specific behavior.
How did species specific behavior that have an instinctual basis or otherwise known as instinctual behavior, constratst w/behaviorists theories and methods.
Theories of learning or learned behavior, was the concern of behaviorists, not instinctual behavior of ethologists; behaviorists bring animals into the lab.
Behaviorists bring animals into the lab to study learned behaviors, ethologists study instinctual behaviors____ in this setting. And too, the behaviorists look for animal outcome (observable data), in the form of these variables.
BEhaviorist bring animals into and study only simple behaviors such as salivation, key pecking, and lever pressing; ethologist observe animal behavior in the animal's natural habitat and look at more complex behavior.
So behaviorists study this type of behavior in contrast to ethologists who study this type in this setting.
Behaviorist, simple behaviors in a lab; Ethologists, complex behaviors in a naturalistic set.
Who established the field of ethology and what were his discoveries.
Konrad Lorenz; imprinting.
Who introduced the experimental method into the field of ethologists and what did these methods allow for in a natualistic setting.
Niko Tinbergen; enabled the construction of controlled conditions outside a lab setting.
Fixed-action patterns (FAP).
Certain action patterns are relatively stereotyped and appear to be species typical
Where do FAP take place w/animals?
Through observation of animal behavior in their natural habitat.
FAP distinguished w/pavlovian theory of unconditioned response in the salvitory reflex of dogs.
Salvitory reflexes are considered to be innate like FAP; difference is FAP tends to be more complex than pavlovian unconditioned response.
Ex of an unconditioned response and FAP behavior.
UR salivating ro an eyebling; FAP rolling an egg back to a nest, or species-typical courship ritual.
FAP are triggered by this also know by this term; are these terms interchangeable?
Sign stimuli or releasers; no they are not interchangeable.
Definition of sign stimuli in triggering an FAP.
Sign stimuli are features of a stimulus that are sufficient to bring about a particular FAP.
Releasers in the process of triggering an FAP.
Are a sign stimuli that function as signals from one animal to another; a release is a particular environmental stimulus that sets off a specific behavior.
Differentiating btw sign stimuli and releaser.
Sign, features sufficient to bring about FAP; releaser are a sign stimuli signals from animal to another; particular enviorn stimulus to trigger a specific behavior.
Ex. of sign stimulus in the most famouse ethology experiment; who was the researcher and w/what species? Which behavior was studied in this species?
Tinbergen's experiment on aggression in male sticklebacks.
Describe Tinbergen's experiment on aggression in male sticklebacks; What is the behavior associated w/male sticklebacks?
Fish whose males establish territories during the spring breeding season; if male swims into the territory of another male, likely to be attacked.
What did Tinbergen find as a result of aggression of one sticklback male aimed at another that invaded the first male stickleback's territory. Name the sign stimulus.
Red belly of the invading stickleback was the most important element in triggering the aggressive behavior.
How did Tinbergen test the red belly as the main factor in triggering aggressive behavior?
Used a crude model w/belly painted red and this model was attacked.
So a red belly is what according to Tinbergen
Sign stimulus and also a releaser, which triggers aggression in male sticklebacks during the spring.
Sign stimulus and releaser can be one and the same? Describe why or why not.
Yes, but not always; in this instance, the red belly was sufficient to bring about an FAP and also was the trigger (releaser) for the FAP to take place (aggression of stickleback, towards other male or fictous model that entered the first sticklebacks territory).
What was an interesting finding in the Tinbergen male stickleback study and the effects of aggression?
Designed a model that elicited the agressive response more often than an actual male stickleback.
Supernormal stimulus describe
A stimulus that is more effective at triggering the FAP than the actual stimulus found in nature.
When does the FAP occur and how? What would occur if the stimulus was removed midway through the FAP?
Follows automatically once the organism perceives the sign stimulus; the animal will continue to perform the actions as if the stimulus was still present, similar to an action potential=all or nothing law.
Innate releasing mechanism (IRM), describe this in light of the inability for animal to stop the FAP once a stimulus has been removed.
A mechanism that exists in the animal's nervous system that serves to connect the stimulus w/the right response.
Ethology basic concepts, explanation, concept; FAP, sign stimuli, releaser.
A stereotyped behavior sequence that does not have to be learned by the animal; features of a stimulus sufficient to bring about a particular FAP; a sign stimulus that triggers social behaviors btw animals.
Ethology basic concepts, explanation, concept; supernormal stimulus, innate releasing mechanism (IRM).
A odel more effective at triggering a FAP than the actual sign stimulus found in nature; a mechanism in the animal's nervous syste that connects sign stimuli w/the correct FAT's.

How do modern ethologists answer the question of why animals behave in a certain way and not in others?
By attempting to discover the evolutionary significance of various behaviors.
Charles darwin and natural selection premise and the area of investigation for modern ethologists.
Natural selection is the key to evolution; based on the premise that not every membere of a species is equally successful at surviving and reproducing.
Natural selection in part is based on the premise that not every species is equally successful at surving and reproducing and also on this premise
That there is vvariation btw individual members of the same species and a portion of this variation has a genetic basis.
In Darwin's natural selection theory which he stated as the key to evolution, the notion that some variation has a genetic basis is manifested how?
To the extent that a genetic variation increases the chances of reproduction, it will tend to be passed down to the next generation.
Darwin's theory of natural selection: Step-By-Step: Three steps; Step 1.
There are genetic differenece btw members of a species
Darwin's theory of natural selection: Step-By-Step: Three steps; step 2, two parts a & b.
a) If a specific genetic variation increases the chances of reproduction, it will tend to be passed down to the next generation; b) if a specific genetic variation decreases the chances of reproduction, it will tend to not be passed down to the next generation.
Darwin's theory of natural selection: Step-By-Step: Three steps; step 3.
Over time, more and more members of the species will tend to have the genetic variation that increases their chance of reproduction and less and less of the species will tend to have the genetic variation that decreases their chance of reproduction.
What does Darwin's theory of natural selection have to do w/behavior?
It is related to a species reproductive fitness.
Describe reproductive fitness
The number of offspring that live to be old enough to reproduce; which suggests that animals will act to increase their reproductive fitness.
Altruism and reproductive fitness
If the anima's behavior decreases its reproductive fitness this is altruism
Essentially how is altruism manifested in Darwinian theory?
Altruist is putting itself in danger, and if doing so does not help its offspring the behavior will decrease its reproductive fitness.
What is the flaw in the altrustic presupposition?
That animals are known to put themselves at risk for fellow species-members
Theory of kin selection and darwinian theory
suggests that animals act to increase their inclusive firness, rather than their reproductive fitness.
Inclusive fitness in association to theory of kin selection.
Takes into account not only the number of offspring who survive to reproductive age, but also the number of other relatives who survive to reproductive age.
Modern ethology is consedered a branch of these disciplines.

Harry Harlow; rhesus monkeys; three types of findings.
Social isolation; contact comfort; learning to learn.
Social isolation; study; outcomes.
Compared raised in isolation w/raised in peer group; isolation hampered social development; when brought together, isolated males did not display normal sexual functioning and females lacked maternal behaviors.
Contact comfort; infants attach for this reason rather than this reason.
Phenomenon of attachment; spent most time w/terrycloth mom and ran to surrogat terry cloth when afraid approached wire mom only to feed; infants attach to their mothers through comforthing experience rather than through feeding.
Harlow; learning to learn and rhesus monkey studies; comparative psychology; what is necessary for learning to take place and to proceed at a rapid rate.
Monkeys became bettr at learning tasks as they acquired different learning experiences; eventually, monkey could learn after only one trial.
R. C. Tyron selectively bred, for this reason.

R. M cooper and John Zubek demostrated the interaction btw_____; in the latter experiment the sectively bred______.
heredity and environm; bright rats performed better than the dull rats in maze problem solving only when both sets of rats were raised in normal conditions.
When did R.M. Cooper and John Zubek discover that both the bright and dull rats performed well and poorly?
Equally well when raised in an enriched environment, lots of food and available activities; performed poorly when raised in an impovershed environment.
Edward Thorndike acquired fame in animal learning w/ his concept of instrumental learning
This type of learning happens through trial, error, and accidental success;

Heredity and enviorn;genetics influenced aggression or experience/environment; sibling mice are spparated at birth and placed w/different parents or in different situations.
In Cross fostering experiments difference in a behavior can be attributed to____.
Experience rather than genetics.
Kandel posited that learning and memory are evidenced by?
Changes in synapses and neural pathways (studied se slug aplysia...Eric kandel).
This much Learning is the relatively _____or ____in behavior as the result of ___.
Permanent or stable change in behavior as a result of experience
In relation to learning as the relatively permanent/stable change in behavior as the result of experience; this is what is__; but diff people have different ideas about ____;
Agreed upon by theorists; exactly why and how animals learn
Some theorists assert that animals learn in order to ____; Others believe that animals learn through ___or ___.
Manipulate rewards and punishments; temporal relationships or pairing.
E.L. Thorndike suggested the ____
Law of effect
Thorndikes law of effect postulated a ____of ____revolving around___; In other words individuals do what ___and stop doing what _____.
Cause and effect chain of behavior, reinforcement; rewards them; doesn't bring some reward.
Thorndike's law of effect was a precursor of ____.
Operant conditioning.
Kurt Lewin developed the ____, which was a forerunner of ____.
Theory of association; forerunner of behaviorism.
Association is ___based on the fact that they___; Organisms associate ___w____and ____ w____; Lewins idea is basically what______later____
Grouping things together based on tthe fact that they occur together in time and space; certain behaviors, certain rewards; certain cues, certain situations.
Ivan Pavlov was the first___for work in ___; during more work investigating __and ___, he accidently uncovered the concept _____
First famous as the winner of a Nobel Prize, work on digestion; dogs and digestion; concept now called classical conditioning.
Classical conditioning is also known as____, involves teaching an organism to____by ____w/a_____
Pavlovian conditioning; respond, a neutral stimulus, pairing the NS, not so NS
Pavlov's dogs began to salivate at the____; the NS (footsteps) had been paired repeatedly with the____.
Sound of Pavlov's assistants footsteps which was a NS; arrival of food
As a result of repeated pairings of the NS (footsteps) w the UCS (food), the dogs began to demonstrate two types of responses____.
The dogs salivated at the sight of food (UCR) and do to pairing the food w/footsteps, the dogs began to salivate when the sound of footsteps was heard (CR).

However, the important finding in Pavlov's conditioning experiment was that the ______;
Dogs began to salivate in response to the light being turned on, without the presence of the food.
Pavlov's light pairing w/food to condition the dog's to salivate in response to either stimulus and to salivate when only the light was turned on proved the theory that____which he formulated through observations made_____;
