Abstract The research evaluated the changes of verbal and spatial working memory with females during 15 days −6° 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. The results demonstrated that the trends of verbal and spatial working memory performance were consistent with that of the control group during the rest. Moreover, in the −6° head-down bed rest conditions, the participants have performed no damage on the working memory ability, and any clinically salient anxiety and depression. The research considered that, compared to the real space environment, individuals' undamaged cognitive functions probably have something to do with the failure of evoking clinical anxiety and depression in the stimulated weightless environment.

    Highlights ► Psychological decrements during space flight. ► The changes in working memory during head-down bed rest. ► The changes in emotion during head-down bed rest.
