Cognitivepsychologiststrytobuildupcognitive modelsoftheinformationprocessingthatgoesoninsidepeople’sminds,includingperception,attention,language,memory,thinking,andconsciousness. Cognitivepsychologybecameofgreatimportanceinthemid-1950s.Severalfactorswereimportantinthis: Dissatisfactionwiththebehavioristapproachinitssimpleemphasisonexternalbehaviorratherthaninternalprocesses. Thedevelopmentofbetterexperimentalmethods. Comparisonbetweenhumanandcomputerprocessingofinformation. Theemphasisofpsychologyshiftedawayfromthestudyofconditionedbehaviorandpsychoanalyticalnotionsaboutthestudyofthemind,towardstheunderstandingofhumaninformationprocessing,usingstrictandrigorouslaboratoryinvestigation. BasicAssumptions Mediationalprocessesoccurbetweenstimulusandresponse: Behavioristsrejectedtheideaofstudyingthemindbecauseinternalmentalprocessescannotbeobservedandobjectivelymeasured.However,cognitivepsychologistsregarditasessentialtolookatthementalprocessesofanorganismandhowtheseinfluencebehavior. Insteadofthesimplestimulus-responselinksproposedbyBehaviorism,themediationalprocessesoftheorganismareimportanttounderstand.Withoutthisunderstanding,psychologistscannothaveacompleteunderstandingofbehavior. Psychologyshouldbeseenasascience: Cognitivepsychologistsfollowtheexampleofthebehavioristsinpreferringobjective,controlled,scientificmethodsforinvestigatingbehavior. Theyusetheresultsoftheirinvestigationsasthebasisformakinginferencesaboutmentalprocesses. Humansareinformationprocessors: Informationprocessinginhumansresemblesthatincomputers,andisbasedon basedontransforminginformation,storinginformationandretrievinginformationfrommemory. Informationprocessingmodelsofcognitiveprocessessuchasmemoryandattentionassumethatmentalprocessesfollowaclearsequence.Forexample: Inputprocessesareconcernedwiththeanalysisofthestimuli.

InformationProcessing InformationProcessing Thecognitiveapproachbegantorevolutionizepsychologyinthelate1950sandearly1960’s,tobecomethedominantapproach(i.e.,perspective)inpsychologybythelate1970s.InterestinmentalprocesseshadbeengraduallyrestoredthroughtheworkofPiagetandTolman. Tolmanwasa‘softbehaviorist’.HisbookPurposiveBehaviorinAnimalsandManin1932describedresearchwhichbehaviorismfounddifficulttoexplain.Thebehaviorists’viewhadbeenthatlearningtookplaceasaresultofassociationsbetweenstimuliandresponses.However,Tolmansuggestedthatlearningwasbasedontherelationshipswhichformedamongststimuli.Hereferredtotheserelationshipsascognitivemaps. Butitwasthearrivalofthecomputerthatgavecognitivepsychologytheterminologyandmetaphoritneededtoinvestigatethehumanmind.Thestartoftheuseofcomputersallowedpsychologiststotrytounderstandthecomplexitiesofhumancognitionbycomparingitwithsomethingsimplerandbetterunderstood,i.e.,anartificialsystemsuchasacomputer. Theuseofthecomputerasatoolforthinkinghowthehumanmindhandlesinformationisknownasthecomputeranalogy.Essentially,acomputercodes(i.e.,changes)information,storesinformation,usesinformation,andproducesanoutput(retrievesinfo).Theideaofinformationprocessingwasadoptedbycognitivepsychologistsasamodelofhowhumanthoughtworks. Theinformationprocessingapproachisbasedonanumberofassumptions,including: Informationmadeavailablefromtheenvironmentisprocessedbyaseriesofprocessingsystems(e.g.,attention,perception,short-termmemory); Theseprocessingsystemstransform,oraltertheinformationinsystematicways; Theaimofresearchistospecifytheprocessesandstructuresthatunderliecognitiveperformance; Informationprocessinginhumansresemblesthatincomputers. TheRoleofSchemas Cognitiveprocessingcanoftenbeaffectedbyschemas(amentalframeworkofbeliefsandexpectationsdevelopedfromexperience).Asyougetolder,thesebecomemoredetailedandsophisticated.

MediationalProcesses MediationalProcesses Thebehavioristsapproachonlystudiesexternalobservable(stimulusandresponse)behaviorwhichcanbeobjectivelymeasured.Theybelievethatinternalbehaviorcannotbestudiedbecausewecannotseewhathappensinaperson’smind(andthereforecannotobjectivelymeasureit). Incomparison,thecognitiveapproachbelievesthatinternalmentalbehaviorcanbescientificallystudiedusingexperiments.Cognitivepsychologyassumesthatamediationalprocessoccursbetweenstimulus/inputandresponse/output. Themediational(i.e.,mental)eventcouldbememory,perception,attentionorproblemsolving,etc.Theseareknownasmediationalprocessesbecausetheymediate(i.e.,go-between)betweenthestimulusandtheresponse.Theycomeafterthestimulusandbeforetheresponse. Therefore,cognitivepsychologists’sayifyouwanttounderstandbehavior,youhavetounderstandthesemediationalprocesses.
