Document Summary

Unconditioned response (typical reflex) move/jump out of water. *unconditioned and conditioned response are always the same. What counts as evidence of learning: the anticipatory response - response occurs after the conditioned stimulus (bell) but before the unconditioned stimulus (food) The learning theory: rescorla-wagner model (1972, a mathematical model of trial-by-trial changes in anticipatory response, error-driven learning, the learner adjusts their expectation on each trial. Learning curves: the rate of a person"s progress in gaining experience or new skills. Classical conditioning: extinction - the weakening of a learned response when the cs is presented without associated us, learning something new, that cs can occur without us. Learning a new response: extinction is not forgetting, relearning doesn"t take as long as original conditioning, spontaneous recovery - unprompted reappearance of extinguished response after time has passed. Relative timing of cs and us matters: trace conditioning: offset of cs before onset of us.
