Approaches to Human CognitionStudy of Cognition:Aims to understand the workings of thehuman mind by studying human behaviour,often using experimental methods.Approaches to Study Cognition:Cognitive Psychology:The attempt to uncoverthe nature of human cognition by observingpeople’s behaviour.Computational Cognitive Science:The attempttousecomputationalmodelstofurtherunderstanding of human cognition.Cognitive Neuroscience:The attempt to useinformation about behaviour and the brainto understand human cognition.Cognitive Neuropsychology:The attempt tounderstandhuman cognition by studyingbrain-damaged patients.General Information Processing Model:Information-Processing Approach:Major Goal:Specify the processesandstructuresinvolvedincognition.This picture depicts a bottom-upand serial processing (one processfollows another).Types of Processing (Parallel vs. Serial):Parallel Processes:CascadedProcesses:don’twaituntilfirstprocess is completed.Discrete (separate) Serial Processes:TypesofProcessing(Bottom-Upvs.Top-DownProcessing):Bottom-UpProcessing:Externalstimuluscauses internal cognitive processes to occur,producing the desired response.Top-Down Processing:Processing influencedbytheindividual’sexpectationsandknowledge.Cognitive Psychology:Uses experimental method to test a researchhypothesis.IV(IndependentVariable):Thevariable(s)[factor/dimension]manipulatedbytheexperimenter.-EachIVhasatleast2levels(conditions).-E.g. drug A vs placebo (2 levels).-E.g. drug A (high dosage) vs drug B(low dosage) vs placebo (3 levels).Downloaded by Jem Bingham ([email protected])lOMoARcPSD|3333134
