Document Summary

Acquisition curves: response strength, latency (cs-cr, time frame of the stimulus, the latency curve is negatively accelerated, output measure, opposite trend of latency. High - order conditioning: pair primary cs with another neutral stimulus (secondary cs, not very effective , cs -ucs bond is no longer reinforced, the cr extinguishes. Extinction: cs no longer paired with ucs, decreases in response strength, cs loses cue value. Note: cs - ucs bond not unlearned. savings and spontaneous recovery: does not take as long to do it again, always there, deal with it in a different fashion. Generalization: degree of responding to stimuli similar to taring stimulus, animal in red with have better hearing. Instrumental or operant conditioning: thorndike and skinner, association of a stimulus and a response. S-r bond is strengthened by reinforcement: law of effect, reinforcement: you will do it again; but if you are punished for it, you probably won"t do it again.
