▁balance , ▁our ▁central ▁nerv ous ▁system ▁will ▁trigger ▁neural ▁processes ▁in ▁order ▁to ▁stabil ise ▁our ▁post ure . ▁In ▁this ▁case , ▁when ▁walking ▁onto ▁a ▁moving ▁platform ▁– ▁such ▁as ▁a ▁moving ▁es cal ator ▁– ▁people ▁will ▁adopt ▁methods ▁to ▁prevent ▁a ▁backwards ▁fall . ▁In ▁the ▁MO V ING ▁tri als ▁of ▁the ▁experiment , ▁these ▁methods ▁consist ▁of ▁a ▁forward ▁s way ▁of ▁the ▁tor so , ▁increased ▁g ait ▁velocity ▁and ▁increased ▁leg ▁EM G ▁activity . ▁Thus , ▁when ▁we ▁step ▁onto ▁a ▁moving ▁es cal ator , ▁we ▁alter ▁our ▁post ure ▁and ▁g ait ▁in ▁order ▁to ▁stabil ise ▁ourselves ▁against ▁this ▁external ▁threat ▁to ▁our ▁balance . ▁ ▁The ▁after - effect ▁consists ▁of ▁an ▁in app ropri ate ▁expression ▁of ▁this ▁method . ▁In ▁the ▁AF TER ▁tri als , ▁instead ▁of ▁walking ▁onto ▁the ▁station ary ▁s led ▁the ▁same ▁way ▁they ▁did ▁for ▁the ▁BE FO RE ▁tri als , ▁subjects ▁adopted ▁a ▁similar ▁method ▁to ▁the ▁MO V ING ▁tri als . ▁This ▁resulted ▁in ▁them ▁walking ▁in app ropri ately ▁fast ▁and ▁excess ively ▁s way ing ▁their ▁tor so ▁when ▁ste pping ▁onto ▁the ▁s led , ▁leading ▁to ▁a ▁sens ation ▁of ▁d izz iness . ▁Similarly , ▁when ▁walking ▁onto ▁the ▁broken ▁es cal ator , ▁people ▁adopt ▁the ▁same ▁method ▁that ▁they ▁use ▁for ▁a ▁moving ▁es cal ator , ▁therefore ▁almost ▁failing ▁to ▁keep ▁their ▁balance . ▁ ▁Dis soci ation ▁between
