Chapter 6 Learning & Memory Flashcards
Any relatively permanent change in behavior brought about by experience or practice.
Learning
When people learn anything, some part of their brain is physically _______ to record what they have learned.
Changed
Any kind of change in the way an organism behaves is ________.
learning
Russian physiologist who discovered classical conditioning through his work on digestion in dogs.
Ivan Pavlov
Learning to make a reflex response to a stimulus other than the original, natural stimulus that normally produces the reflex.
Classical conditioning
A naturally occurring stimulus that leads to an involuntary response.
Unconditioned stimulus (UCS)
An involuntary response to a naturally occurring unconditioned stimulus.
Unconditioned response (UCR)
Stimulus that becomes able to produce a learned reflex response by being paired with the original unconditioned stimulus.
Conditioned stimulus (CS)
Can become a conditioned stimulus when paired with an unconditioned stimulus.
Neutral stimulus (NS)
Learned reflex response to a conditioned stimulus. Sometimes called conditioned reflex.
Conditioned response (CR)
(classical conditioning concept)
Ice cream truck
Conditioned stimulus (CS)
(classical conditioning concept)
Salivation when one hears ice cream truck bell
Conditioned response (CR)
Repeated pairing of the NS and the UCS; the organism is in the process of acquiring learning.
Acquisition
Basic principles of classical conditioning
• CS must be 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.
Tendency to respond to a stimulus that is only similar to the original conditioned stimulus with the conditioned response.
Stimulus generalization
Tendency to stop making a generalized response to a stimulus that is similar to the original conditioned stimulus because the similar stimulus is never paired with the unconditioned stimulus.
Stimulus discrimination
disappearance or weakening of a learned response following the removal or absence of the unconditioned stimulus (in classical conditioning) or the removal of a reinforcer (in operant conditioning)
Extinction
Reappearance of a learned response after extinction has occurred.
Spontaneous recovery
- Strong conditioned stimulus is paired with a neutral stimulus
- Neutral stimulus becomes a second conditioned stimulus
Higher-order conditioning
Emotional response that has become classically conditioned to occur to learned stimuli
Conditioned emotional response (CER)
____ may lead to phobias—irrational fear responses
CERs
Classical conditioning of a reflex response or emotion by watching the reaction of another person
Vicarious conditioning
Development of a nausea or aversive response to a particular taste because that taste was followed by a nausea reaction
Conditioned taste aversion
The tendency of animals to learn certain associations such as taste and nausea, with only one or few pairings due to the survival value of the learning.
Biological preparedness
original theory in which Pavlov stated that classical conditioning occurred because the conditioned stimulus became a substitute for the un conditioned stimulus by being paired closely together
Stimulus substitution
Modern theory in which classical conditioning is seen to occur because the conditioned stimulus provides information or an expectancy about the coming of the unconditioned stimulus
Cognitive perspective
The learning of voluntary behavior through the effects of pleasant and unpleasant consequences to responses
Operant conditioning
Law stating that if a response is followed by a pleasurable consequence, it will tend to be repeated, and if a response is followed by an unpleasant consequence, it will tend not to be repeated
Thorndike’s law of effect
Was a behaviorist; he wanted to study only observable, measurable behavior. Gave “operant conditioning” its name.
B.F. Skinner
Any behavior that is voluntary
Operant
Any event or stimulus, that when following a response, increases the probability that the response will occur again.
Reinforcement
Any reinforcer that is naturally reinforcing by meeting a basic biological need, such as hunger, thirst, or touch
Primary reinforcer
Any reinforcer that becomes reinforcing after being paired with a primary reinforcer, such as praise, tokens, or gold stars
Secondary reinforcer
The reinforcement of a response by the addition or experience of a pleasurable stimulus
Positive reinforcement
The reinforcement of a response bythe removal, escape from, or avoidance of an unpleasant stimulus
Negative reinforcement
A response that is reinforced after some—but not at all—correct responses tends to be very resistant to extinction
Partial reinforcement effect
Reinforcement of each and every correct response
Continuous reinforcement
Interval of time that must pass before reinforcement becomes possible is always the same
Fixed Interval
The interval of time that must pass before reinforcement becomes possible is different for each trial or event.
Variable interval
