What is a relatively permanent change in an organism's behavior due to experience?
|
Learning!!
|
|
|
Associative learning:
|
learning that certain events occur together
|
|
|
Classical conditioning:
|
the type of learning in which an organism comes to associate a stimui
|
|
|
Unconditioned stimulus (US):
|
a stimulus that unconditionally - naturally and automatically - triggers a response
|
|
|
Unconditioned response(UR):
|
the unlearned, naturally occurring response to the (US)
|
|
|
Conditioned stimulus (CS):
|
an originally irrelevant stimulus that, after association with an Unconditioned stimulus(US), comes to trigger a Contitioned response (CR)
|
|
|
Conditioned response (CR):
|
the learned response to a previously natural stimulus (CR) = dogs salivation to the toning bell
|
|
|
Extention:
|
The diminished responding that occurs when the CS no longer signals the impending US
|
|
|
Operant conditioning:
|
a type of learning in which behavior is strengthened if followed by a reinforcer or diminished if followed by a punisher
|
|
|
sa procedure in which reforcers, such as food, gradually guide an animal's actions toward a desired behavior:
|
shaping!
|
|
|
Positive reinforcement:
|
increasing behaviors by presenting positive stimuli (the presence of something desirable)
|
|
|
Negative reinforcement:
|
increasing behaviors by stopping or reducing negative stimuli. (the ABSENSE of something not desirable) don't confuse with punishment.
|
|
|
The goal of reinforcement is to _____.
|
incraese the linkelyhood of a behavior being repeated
|
|
|
Punishment is trying to ____ a behavior.
|
stop
|
|
|
Partial (intermittent) reinforcement:
|
-Reinforcing a respon only part of the time
-Results in slower acquisition -much greater resistance to extintion |
|
|
4 Types of Partical (intermittent) reinforcement:
|
1.Fixed-Ratio
2. Variable-Ratio 3.Fixed-interval 4.variable-interval |
|
|
Fixed-Ratio:
|
reinforces after a specific number of responses
|
|
|
variable-ratio
|
reinforces a response after an unpredictable number of responses
|
|
|
fixed-interval
|
reinforces after a specific time has elapsed
|
|
|
variable-interval
|
reinforces responses at unpredictable time intervals
|
|
|
Modeling:
|
the process of obeserving and imitating a specific behavior
|
