The research evaluated the changes of verbal  and spatial working memory with females during 15 days _61 head-down bed rest.We  used 2-back task to evaluate the working memory ability on four time points:the  fifth day before the rest,the fifth day and the tenth day in the rest and the  fifth day after the rest,as well as record the participants’depression and  anxiety feelings using Beck Anxiety Inventory(BAI) and Beck Depression  Inventory(BDI) simultaneously. There results demonstrated that the trends of  verbal and spatial working memory performance were consistent with that of the  control group during there rest. Moreover, in the _61 head-down bed rest  conditions, the participants have performed no damageon the working memory  ability,and any clinically salient anxiety and  depression.Theresearchconsideredthat,comparedtothe real  spaceenvironment,individuals’undamaged cognitive functions probably have   something to do with the failure of evoking clinical anxiety and depression in  the stimulated weightless environment.
