Abstract This study investigated both confinement and gender effects on risk taking and reaction times during long periods of confinement and extended wakefulness. Four groups of three men and three women were studied for 10 consecutive days including a seven-day confined period or a seven-day baseline condition preceding one control night of normal sleep, one night of sleep deprivation and one recovery night in the laboratory. Risk-taking propensity (EVAR scale) and simple reaction times were monitored at regular intervals. During sleep deprivation, risk-taking propensity decreased and remained stable the following day in the confinement condition while it increased after the baseline period. Other findings are discussed.
