Abstract

Visual search researches have demonstrated target prevalence affected the search performance. However, almost all studies were conducted in static searches. The aim of present study is, using more ecologically valid dynamic visual search, to examine whether different static and dynamic displays affect prevalence effects in screening tasks. Three display patterns were deployed by manipulating the display movement velocity. The results showed that the low prevalence effect existed both in static search and more ecologically valid dynamic visual search. The disciplines of prevalence effects partially applied in dynamic visual search.
