Cards

Term
learning
Definition

 

A relatively permanent and potential change in behavior involving specific stimuli and/or responses that occurs as a result of experience with those or similar stimuli or responses
Term
unconditioned response (UR)
Definition
in classical conditioning, the unlearned, naturally occuring response to the unconditioned stimulus (US), such as salivation when food is in the mouth.
Term
Unconditioned stimulus (US)
Definition
In classical conditioning, a stimulus that unconditionally, naturally and automatically- triggers a response.
Term
conditioned response(CR)
Definition
In classical conditioning, an originally irrelevant stimulus that, after association with an unconditioned stimulus (US), comes to trigger a conditioned response.
Term
Conditioned Stimulus (CS)
Definition
in classical conditioning, an originally irrelevant stimulus that, after association with an unconditioned stimulus (US), comes to trigger a conditioned response.
Term
Acquisition
Definition
the initial stage in classical conditioning; the phrase associating a neutral stimulus with an unconditioned stimulus so that the neutral stimulus comes to elicit a conditioned response.
Term
extinction
Definition
the diminishing of a conditioned response; occurs in classical conditioning when an unconditioned stimulus (US) does not follow a conditioned stimulus.
Term
spontaneous recovery
Definition
the reappearance after a pause, of an extinguished conditioned response.
Term
generalization
Definition
the tendency, once a response has been conditioned, for stimuli similar to the conditioned stimulus to elicit similiar responses.
Term
discrimination
Definition
in classical conditioning, the learned ability to distinguish between a conditioned stimulus and stimuli that do not signal an unconditioned stimulus.
Term
difference btw stimulus-response learning and stimulus-stimulus learning
Definition

stimulus-response: cs elicits cr. learn when cs present

Stimulus-stimulus: cs elicits cr. learn relationship btw cs and us

Term
Garcia&Koeling's state aversion experiment
Definition
note
Term
associative bias
Definition
bias—predisposition to learn associations between some stimuli but not others
Term
phobias
Definition
Intense fear of a specific object or situation
Term
flooding
Definition
exposure to a vast amount of feared stimulus
Term
systematic disensitization
Definition
progessive exposure to a feared stimulus and replacement of a fear response with relaxation
Term
Little Albert
Definition

11 years old infant, no fear of white rat.

White rat + noise => fear. Generalization => fear rabbit, dog, stealskin coat but not dissimilar object such as toys.
