Chapter 6 Flashcards
Learning
Any relatively permanent change in knowledge or
behavior that can be attributed to experience.
Associative learning
The formation of simple associations between various stimuli and responses.
Classical conditioning
A form of learning in which reflex responses are associated with new stimuli.
Unconditioned stimulus (US)
Something that elicits a response without any prior experience.
Unconditioned response (UR)
Response to a stimulus that
requires no previous experience.
Neutral stimulus (NS)
A stimulus that does not evoke
a response.
Conditioned stimulus (CS)
Neutral stimulus that, through
pairing with an unconditioned stimulus, comes to elicit a learned response.
Conditioned response (CR)
Learned reaction elicited by pairing an originally neutral stimulus with an unconditioned stimulus.
Extinction (classical conditioning)
Weakening of a learned
response by repeatedly presenting the conditioned stimulus without the unconditioned stimulus.
Spontaneous recovery
Reappearance of a learned response after its apparent extinction.
Stimulus generalization
Tendency to respond to stimuli similar to a conditioned stimulus.
Stimulus discrimination
The learned ability to respond
differently to similar stimuli
Conditioned emotional response (CER)
An emotional
response that has been linked to a previously nonemotional stimulus by classical conditioning.
Operant conditioning chamber (Skinner box)
An apparatus designed to study operant conditioning in animals.
Reinforcer
Any event that reliably increases the probability or
frequency of responses it follows.
Positive reinforcement
Occurs when a response is followed by a reward or other positive event.
Negative reinforcement
Occurs when a response is followed by an end to discomfort or by the removal of an unpleasant event.
Punisher
Any event that decreases the probability or frequency of
responses that it follows.
Positive punishment (punishment)
Any event that follows a
response and decreases its likelihood of occurring again; the process of suppressing a response.
Negative punishment (response cost)
Removal of a positive
reinforcer after a response is made.
