PsychologyofSport 1) Describethedifferencebetweenintrinsicandextrinsicmotivation. I ntrinsicmotivationcomesfromwithinaperson,drivenbyaninherenttendencyto learn,accomplishthings,and/orexperiencesensations.Itrequiresfeelingsof competencyandasenseofautonomytostayintrinsicallymotivated. Extrinsicmotivationisdrivenbyexternalfactors,likerewardsorrecognitionfrom others. 2) Howdorewardsaffectintrinsicmotivation? Rewards(boththeinformationalandcontrollingaspectofthem)canincreaseor decreaseintrinsicmotivation,dependingonhowtheindividualevaluatesthem. 3) Describethesourcesthatleadtoselfefficacyandtheoutcomesthatresult. Whatarethetwomoderatingvariables? Self-efficacyisaperson'sbeliefintheirabilitytocompleteataskorachieveagoal.
