ific ▁Method ▁ ▁A ▁key ▁goal ▁of ▁early ▁cogn itive ▁psych ology ▁was ▁to ▁apply ▁the ▁scientific ▁method ▁to ▁the ▁study ▁of ▁human ▁cogn ition . ▁This ▁was ▁done ▁by ▁design ing ▁experiments ▁that ▁used ▁computational ▁models ▁of ▁artificial ▁intelligence ▁to ▁system atically ▁test ▁theories ▁about ▁human ▁mental ▁processes ▁in ▁a ▁controlled ▁labor atory ▁setting . ▁ ▁Med iation ▁and ▁information ▁processing ▁ ▁When ▁defining ▁the ▁" C ogn itive ▁Appro ach ," ▁Ul ric ▁Ne isser ▁says ▁that ▁humans ▁can ▁only ▁interact ▁with ▁the ▁" real ▁world " ▁through ▁inter medi ary ▁systems ▁that ▁process ▁information ▁like ▁sens ory ▁input . ▁As ▁understood ▁by ▁a ▁cogn itive ▁scient ist , ▁the ▁study ▁of ▁cogn ition ▁is ▁the ▁study ▁of ▁these ▁systems ▁and ▁the ▁ways ▁they ▁process ▁information ▁from ▁the ▁input . ▁The ▁processing ▁includes ▁not ▁just ▁the ▁initial ▁struct uring ▁and ▁interpretation ▁of ▁the ▁input ▁but ▁also ▁the ▁storage ▁and ▁later ▁use . ▁ ▁Steven ▁P ink er ▁claims ▁that ▁the ▁cogn itive ▁revolution ▁brid ged ▁the ▁gap ▁between ▁the ▁physical ▁world ▁and ▁the ▁world ▁of ▁ideas , ▁concepts , ▁mean ings ▁and ▁intent ions . ▁It ▁un ified ▁the ▁two ▁world s ▁with ▁a ▁theory ▁that ▁mental ▁life ▁can ▁be ▁explained ▁in ▁terms ▁of ▁information , ▁computation ▁and ▁feedback . ▁Therefore , ▁reasoning , ▁intelligence , ▁imagination , ▁and ▁cre ativity ▁are ▁forms ▁of ▁information ▁processing , ▁a ▁physical ▁process . ▁ ▁Inn aten ess ▁ ▁In ▁his ▁ 1 9 7 5 ▁book ▁Ref lections ▁on ▁Language , ▁No am
