PSCH 100 Lecture Notes - Lecture 7: Classical Conditioning, Operant Conditioning, Habituation
Document Summary
Classical conditioning: a procedure in which a neutral stimulus is repeatedly paired w/ a stimulus that already triggers a reflex response until the neutral stimulus alone evokes a similar reflex response. Reflex: swift automatic response to a stimulus. Unconditioned stimulus (ucs): already elicits a response w/o learning. Unconditioned response: (ucr): the automatic, unlearned reaction to the ucs. Conditioned stimulus (cs): begins as a neutral stimulus, but after pairing w/ the. Extinction: cr decreases. no longer predicts ucs. Reconditioning: quick learning of cr after extinction. Spontaneous recovery: reappearance of cr after extinction. Signal strength: strong signal. ex: strong alarm. Second-order conditioning: new stimulus to replace cr. Operant conditioning: process where an organism learns to do things that cause positive consequences and avoids negative ones. Escape conditioning: learn to make a response to end an aversive stimulus. Avoidance conditioning: respond to a signal to avoid exposure to aversive stimulus. Nonassociative learning: impact of one particular stimulus.
