Chapter 5 - Learning Flashcards
Learning
- Any relatively permanent change in behavior or practice.
- Part of brain is physically changed to record what has been learned.
- Not all change accomplished through learning; some is maturation.
Ivan Pavlov
- Russian Physiologist: Discovered classical conditioning through his work on digestion in dogs.
Classical Conditioning
- Learning to make a reflex response to stimulus other than original, natural stimulus that normally produces the reflex.
Unconditioned stimulus (UCS)
- Naturally occurring stimulus that leads to an involuntary response.
Unconditioned response (UCR)
- Involuntary response to naturally occurring or unconditioned stimulus.
Conditioned stimulus (CS)
- Stimulus that becomes able to produce a learned reflex response by paired with original unconditioned stimulus.
Conditioned response
- In classical conditioning, a learned response to a conditioned stimulus.
Neutral stimulus (NS)
- Can become conditioned stimulus when paired with unconditioned stimulus.
- “Conditioned reflex”.
Acquisition
- Repeated pairing of NS and UCS; organism is in process of acquiring learning.
Few basic principles researches discovered
- CA must come before UCS
- CS and UCS must come very close together in time - ideally, only several seconds apart.
- Neutral stimulus must be paired with the UCS several times, often many times, before conditioning can take place.
- CS usually some stimulus that is distinctive or stands out from other competing stimuli.
Stimulus generalization
- Tendency to respond to a stimulus that is only similar to the original conditioned stimulus with the conditioned response.
Stimulus discrimination
- Tendency to stop making generalized response to a stimulus that is similar to original conditioned stimulus because the similar stimulus is never paired with unconditioned stimulus.
Extinction
- Disappearance or weakening if learned response following removal or absence of unconditioned stimulus (in classical conditioning) or removal of reinforcer (in operant conditioning).
Spontaneous Recovery
- Reappearance of a learned response after extinction has occurred.
- Learning: Relatively permanent change in behavior.
Higher-order conditioning
- Strong conditioned stimulus is paired with neutral stimulus.
- Neutral stimulus becomes a second conditioned stimulus.
Conditioned emotional response (CER)
- Emotional response that has become classically conditioned to occur to learned stimuli.
- CERs may lead to phobias-irrational fear responses.
Stimulus substitution
- Original theory in which Pavlov stated that classical conditioning occurred because the conditioned stimulus became a substitute for unconditioned stimulus by being paired closely together.
Cognitive perspective
- Modern theory in which classical conditioning is seen to occur because the conditioned stimulus provides information or an expectancy about the coming of unconditioned stimulus.
Vicarious Conditioning
- Classical conditioning of a reflex response or emotion by watching the reaction of another person.
Conditioned taste aversion
- Development of a nausea or aversion response to particular taste because taste was followed by nausea reaction.
- Occurs after only one association.
Biological preparedness
-Tendency of animals to learn certain associations (taste and nausea) with only one or few pairings due to survival value of the learning.
Operant conditioning
- Learning of voluntary behavior through the effects of pleasant and unpleasant consequences to responses.
Thorndike’s law of effect
- If a response is followed by pleasurable consequences, it will tend to be repeated.
- If response is followed by an unpleasant consequence, it will tend not to be repeated.
B.F Skinner
- Behaviorist; Wanted to study only observable, measurable behavior.
- gave “operant conditioning “ it’s name.
Operant
- Any behavior that is voluntary.
- Learning depends on what happens after the response: the consequence.
Reinforcement
- Any event or stimulus, when following a response, increases the probability that response will occur again.
