Animal models of human behavioral or cognitive processes are essential for studying mechanisms of these processes. A choice reaction time task was developed for assessing sustained attention in rats; a previous study showed that rats perform the task as predicted from other sustained attention tasks in rats and humans. In this study, we measured the behavior of humans in a choice reaction time task procedurally matched to the task for rats, and examined the effect of decreasing the presentation rate of stimulus through prolonging the inter-trial intervals, which was previously shown to affe...
