PSYCH 101 Lecture Notes - Lecture 16: Classical Conditioning, Exposure Therapy, Aversion Therapy
Document Summary
Classical conditioning learning to associate two stimuli (song + pleasant event), such that one stimulus (the song) comes to produce a response (feeling happy) that originally was only produced by the other stimulus (the pleasurable event). Pavlov discovered that when a stimulus is associated with food, dogs will learn to associate the stimulus with food, and will salivate. Classical conditioning alerts organisms to stimuli that signal the impending arrival of an important event. Figured that if salivation could be conditioned, so might other bodily processes. Tone (cs) + food (ucs) salivation (ucr) Period during which a response is being learned. Food = saliva therefore food = unconditioned stimulus (ucs) Tone + food pairing = learning trial. Tone food tone = conditioned stimulus (cs) Cs is paired multiple tomes with ucs to establish a strong cr. Fastest: forward trace pairing (cs appears before ucs) tone before food. Slower: simultaneous pairing (cs appears with ucs) tone + food same time.
