Document Summary

Chapter 7- learning & adaptation: role of experience 1: learning: experience produces relatively enduring change in organism"s behaviour/capabilities, capabilities: knowing how vs doing, personal adaptation: ever-changing circumstances/environments. Classical conditioning: organisms learns to associate 2 stimuli; ex. song - > happiness, ivan pavlov: measured dogs salivary glands. Extinction & spontaneous recovery: extinction: cs is presented repeatedly in absence of ucs, cr weakens & eventually disappears, spontaneous recovery: extinguished cr, although weakened, has reappeared, w/o new learning trials; ex. repeated trials=treats anxiety. Chapter 7- learning & adaptation: role of experience 2: stimulus generalization: greater stimulus similarity, greater chance cr will occur. Ex. animal responds to rustling bushes; some will be false alarms: discrimination: distinguish irrelevant sounds from those that may signal danger. Ex. animal doesn"t get scared at every noise=distinguishes; would exhaust itself. Ex. mother bit by big dogs=fear, son pleads for dog, get small dog, mother=okay, son complains. High-order conditioning: neutral stimulus becomes cs after being paired w/ already established cr.
