Document Summary

Stimulus elicits a response that has survival value. Occurs when neutral stimulus is paired with biological relevant stimulus. Unconditioned stimulus (us): the biologically relevant stimulus (food, loud sound, air puff) Unconditioned response (ur): the reaction to the ucs (reflexive) Conditioned stimulus (cs): the stimulus paired with the ucs (not necessarily biologically relevant) Conditioned response (cr): the response elicited, after repeated pairing, by the cs (resembles the ur) Cs: click sound cr: salivation (switching back and forth from click and hotdog, trains you to salivate) Cs: light cr: eye blink (shining light in your eye then you blink) Stimuli similar to the cs elicit the response. Cr elicited by narrow range of stimuli. Contiguous: refers to bell and shock occurring together. Bell, shock, flinch, bell, shock, flinch, bell, shock, flinch = bell flinch. Bell, shock, flinch, shock, flinch, bell, shock flinch, bell, bell = no flinch to bell. Cr learned more rapidly when ucs is strong.
