This study evaluates the effect of sleep on learning-based decision-making. Twenty-four healthy volunteers were allocated randomly to two groups: a sleep group and a wake group. A modified Iowa gambling task was administered before and after a 12-h period in which the sleep group slept about 8 h and the other group remained awake. The two groups%26apos; advantageous decision-making during the initial learning phase did not differ, but the advantageous choices of the sleep group improved more than that of the wake group after the 12-h period, suggesting that sleep may have facilitated and/or retained advantageous decision-making.
