Document Summary
Uninterested math students: bad at math, no interest in math, pursued in self-directed learning conditions. Long term only: no goals, no training. Long + short term ok: no goals ok, control worst (long term goals too far away, reward and value are worth less) Learning is proportional to surprise: more surprising it is, more learning happens. Extinction: acquisition of association (between bell and dog). Rabbit eye blink conditioning: bell associated with bell and puff of air, # of responses high in beginning, then constant, then gradually stops blinking (negative slope), eventually response goes away. Standard classical conditioning: before training -> shock = rat jumps, during training -> tone + shock = rat jumps, after training -> tone only = rat jumps. Principle of frequency: when two or more stimuli are paired, the more they will be associated. Training phase 2 -> tone + light + shock = rat jumps. Phase 2 -> tone + light + shock = rat jumps.
