Suboptimal Strategy in Performing Coincident Timing Task under Risk

Abstract

The best performance often goes hand in hand with risk in many sports. Players are engaged in considering how much risk they take. Some studies reported that movement strategy is modified by risk-sensitivity. Here, we investigated how people responded under risk to which high gain got closer to zero gain. We designed new coincident timing task in which participants were rewarded with the highest score if they pressed a button just at a target time (2300 ms) but they did not get a score if they responded after the target time. In this task, the participants should take the variability of their response into account and take a risk-neutral strategy to get the highest total score that was theoretically calculated. However, we found out that the participants took a risky response compared with an estimated optimal response. This risk-seeking strategy degraded a task performance. These results suggest that not only small variability in response but also taking an optimal strategy is important to get higher performance under risk.
