Chp. 6 Learning Flashcards
Learning
A relatively enduring change in behavior or thinking that results from experience.
Habituation
Basic form of learning is evident when an organism does not respond as strongly or as often to an event following multiple exposures to it.
Neutral Stiumulus
Does not cause a relevant automatic or reflexive response.
Acquisition
Initial learning phase in both classical and operant conditioning
Extinction
The conditioned response (CR) decreases and eventually disappears; in operant conditioning, the disappearance of a learned behavior through the removal of its reinforcers
Spontaneous Recovery
The reappearance of a conditioned response following its extinction
Unconditioned Stimulus (US)
Automatically triggers an involuntary response without any learning needed
Unconditioned Response (UR)
A reflexive, involuntary response to an unconditioned stimulus
Conditioned Stimulus (CS)
A previously neutral stimulus that an organism learns to associate with an unconditioned stimulus
Conditioned Response (CR)
A learned response to a conditional stimulus
Stimulus Generalization
After an association is forged between the CS and the CR, the learner often responds to similar stimuli as if they are the original CR.
Example: If a dog in Pavlov’s experiment heard a sound w/ different qualities they still salivated; a stimulus similar to CS
Stimulus Discrimination
The ability to differentiate between a particular CS and other significantly different stimuli is stimulus differentiation. Example: Pavlov’s dogs associate meat w/ high pitched sounds, they salivate when they hear it. If they hear a lower pitched sound they may NOT salivate.
Conditioned Taste Aversion
Form of classical conditioning that occurs when an organism learns to associate the tastes of a particular food or drink w/ illness. Example: Food poisoning
Positive Reinforcement
Adding a reward; you exercise a few times & feel better, leading you to exercise more often
Negative Reinforcement
Removing an unpleasant stimulus; Aspirin relieves headache and leads to more Aspirin use
Positive Punishment
Adding unpleasant stimulus; getting speeding ticket, leads to less punishment
Negative Punishment
Removing a desirable stimulus; getting grounded, leads to you breaking the rules less
Continuous Reinforcement
Every target behavior is reinforced
Partial Reinforcement
Target behaviors are reinforced intermittently
Primary Reinforcer
Satisfies a biological need; innate reinforcer. Ex. food & water
Secondary Reinforcer
Does not satisfy a biological need but often gains power through its association w/ a primary reinforcer. Ex. money & good grades
Abuse of Punishment
Is often applied unequally, may inhibit learning new & better responses, and often triggers escape/aggression
When Punishment Works
Presented w/out delay, consistent, and consequence is logical
Observational Learning
Learn by watching and imitating other people
