Psyc: Chp. 5
Classical Conditioning
Origins
-
Pavlov's investment with psychology began as a result of observation. While investigating the role of salvia in digestion.
Principles
-
Reflex: unlearned behavior governed by nervous system occurs automatically when appropriate stimulus is presented.
When two stimuli (neutral stimulus, natural stimulus) are repatedly being paired netural stimulus elicits basic reflex response as natural stimulus.
-
UCS UCR CS CR
Unconditioned stimulus (UCS): Natural stimulus that refelxively elicits a response without prior larning.
Unconditioned response (UCR): Unlearned, reflexive response that is elicited by unconditioned stimulus.
Conditioned stimulus (CS): Formely netural stimulus that acquires the capacity to elicit a refexive response.
-
The learning process involves pairing a neutral stimulus with a response-producing stimulus until the natural stimulus elicits the same response.
-
Generalization: Learned response not only to original stimulus but to other, similar stimuli as well.
-
Spontaneous recovery: Reappearance of extinguished conditioned response after s period of time without exposure to conditioned stimulus.

Behaviorism
-
-
all behavior, no matter how complex, can be reduced to a simple stimulus – response features
