-Learning to associate two events
Classical (or Pavlovian) Conditioning
-We learn to associate two stimuli (in which a previously neutral stimulus comes to elicit a response through its association with a stimulus that naturally brings about the response)
Operant Conditioning
-We learn to associate a response and its consequence
Ivan Pavlov
-Russian physician/ neurophysiologist
-studied digestive secretions
-nobel prize 1904
Pavlov’s Classic Experiment

Neutral Stimulus
-before conditioning, a stimulus that the does not naturally bring about a response.
Unconditioned Stimulus & example
-UCS, stimulus that naturally and automatically brings about a response, without having been learned.
-Smell of food
Unconditioned Response (2) and example
-UCR, unlearned, natural response to the unconditioned stimulus. (needs no training )
-The event that takes on new meaning through conditioning.
-salivation at the smell of food Involuntary response or reaction
Conditioned Stimulus and example
-CS, a once neutral stimulus that comes to elicit a CR after it has been paired with an unconditional stimulus. originally irrelevant stimulus that, after association with an unconditioned stimulus, comes to trigger a conditioned response
Conditioned Response (2) and example
-CR, learned response to a previously neutral conditioned stimulus.
-The new behavior that is acquired through learning.
-excitement of bell sound that leads to food
Acquisition (3) (in classical and operant conditioning)
-the initial stage in classical conditioning.
-the phase associating a neutral stimulus with an unconditioned stimulus so that the neutral stimulus comes to elicit a conditioned response
-in operant conditioning, the strengthening of a reinforced response
Extinction (3) (in classical and operant conditioning)
-diminishing of a CR
-in classical conditioning, when a UCS does not follow a CS
-in operant conditioning, when a response is no longer reinforced
Spontaneous Recovery
-reappearance, after a rest period, of an extinguished CR
-tendency for stimuli similar to CS to elicit similar responses
-in classical conditioning, the learned ability to distinguish between a CS and other stimuli that do not signal a UCS
-Behavior is strengthened if followed by reinforcement and diminished if followed by punishment
-occurs when people or animals learn by the consequences of their responses.
-These consequences may consist of either reinforcement or punishment.
Law of Effect
-Thorndike’s principle that behaviors followed by favorable consequences become more likely, and behaviors followed by unfavorable consequences become less likely
Operant Behavior
-operates (acts) on environment
-produces consequences
Respondent Behavior
-occurs as an automatic response to stimulus
Skinner Box
-chamber with a bar or key that an animal manipulates to obtain a food or water
-operant conditioning procedure in which reinforcers guide behavior toward closer approximations of a desired goal
-any event that strengthens the behavior it follows
Conditioned Reinforcer or secondary reinforcer
-reinforcers that acquire positive value through experiences (money, smiles, grades)
Positive reinforcement
-occurs when something is added to increase the response rates
Negative reinforcement
-which is different from punishment, occurs when something is removed in order to increase the response rate
Two kinds of punishment
-Positive punishment
-Negative punishment
Positive punishment
-when something is given to decrease the response rate
Negative punishment
-consists of removing something to decrease the response rate
Disadvantages to using punishment
-Often ineffective—if not delivered right away
-Use of physical punishment: teach that aggression is OK
-Begin to fear the “punisher”
-Physical punishment given by angry person who may be more likely to lose control
-Reduces self esteem of recipient
-Does not convey info about what is appropriate behavior
To be effective in punishment:
-to be accompanied by specific info about behavior being punished; along with specific suggestions concerning more desirable behaviors
Cognitive-Social learning theory
-The study of the thought processes that underlie learning
Observational Learning
- Learning through observing the behavior of another person called a model
learning by observing others
Alfred Bandura’s Experiments (example and definition)
-Bobo doll
-we look and we learn
-process of observing and imitating a specific behavior
-A person serving as an example to an observer; if a model’s behavior is rewarded, the observer may imitate that behavior
Cognitive Map
-mental representation of the layout of one’s environment
-Example: after exploring a maze, rats act as if they have learned a cognitive map of it
Latent Learning
-Learning in which a new behavior is acquired but not demonstrated until reinforcement is provided
Intrinsic Motivation
-desire to perform a behavior for its own sake and to be effective
Extrinsic Motivation
-desire to perform a behavior due to promised rewards or threats of punishments
behavior modification
-A technique for promoting the frequency of desirable behaviors and decreasing the incidence of unwanted ones
Brian's mother prepared a tuna sandwich. The mayo she used had been left out too long and was tainted. Not long after eating, Brian felt nauseated and had to rush to the bathroom. Thereafter, the mention of a tuna sandwich would send Brian scurrying to the bathroom with a rolling stomach. What is the UCR, UCS, CR, and CS?
UCR: being sick
UCS: bad mayo
CR: nausea feeling
CS: tuna sandwich
-persistence of learning over time through the storage and retrieval of information

State-dependent Memory
-what is learned in one state (while one is high, drunk, or depressed) can more easily be remembered when in same state
Proactive (forward acting) Interference
-disruptive effect of prior learning on recall of new information
Retroactive (backwards acting) Interference
-disruptive effect of new learning on recall of old information
Source Amnesia
-attributing to the wrong source an event that we experienced, heard about, read about, or imagined (misattribution)

-already seen
Motivated Forgetting
-people unknowingly revise memories
-Forgetting can result from failure to retrieve information from long-term memory

Memory Construction
-We filter information and fill in missing pieces
-Most people can agree on the following:
*Injustice happens
*Incest and sexual abuse happens
*Forgetting happens
*Recovered memories are commonplace
*Memories recovered under hypnosis or drugs are especially unreliable
*Memories of things happening before age 3 are unreliable
*Memories, whether false or real, are upsetting
