Abstract

In visual search tasks, the ratio of target-present to target-absent trials has important effects\non miss rates. In this study, we examined whether the target prevalence effect occurs in a haptic\nsearch task by using artificial tactile maps. The results indicated that target prevalence has effects\non miss rates, sensitivity, and criterion. Moreover, an increase in miss rates in the low-prevalence\ncondition (10%) was strongly correlated with a decrease in search termination times (target-absent\nreaction times). These results suggest that the prevalence effect on haptic search is caused by a\ndecrease in the search termination time and a shift in decision criterion and a decrease in sensitivity.
