PSYC2071 Study Guide - Final Guide: Sug, Brain-Derived Neurotrophic Factor, Cue Reactivity
Document Summary
Human associative learning: learning happens continually through life, al: Allows people to build rep. of envir. Alter / adapt behav. to exploit stat regularities in envir i. e. find food. Classic approach = link based approach: contingency: +ve contingency = e2 likely to depend on e1. -ve contingency = e2 likely to prevent e1 occurring. 0 contingency = no relat. b/t events. Dickinson, shanks & evenden 84": classic tank study rolling across screen. After each cond. asked: how effective were the firing of shells in the previous set? : peoples judgements of causality decline in relation to p. Firing makes no diff: outcome density bias: Judgements higher when p(bang) is higher even when p is equal. Learning is gradual even though p doesn"t change. How likely is it that a or b causes outcome. Ratings sig. lower in compound case less certain judgements. Rating lower cause other cue is present @ same time. People don"t learn about each cue independently.
