Changing the speed and order of attentional selection in visual search.

ABSTRACT: Seminal event-related potential (ERP) studies of visual search reported that young adults serially inspect two singletons when searching for a target (serial search), but later results showed that the second singleton can be selected while the first singleton is still attended (partially parallel search). These contrasting results indicate that some yet-to-be identified factor can affect the speed of search. We hypothesized that single-target detection tasks promote serial inspection while dual-target comparison tasks promote parallel inspection. We recorded ERP activities associated with attentional selection (N2pc) and subsequent identification (SPCN) to track attentional processing of two singletons while healthy young adults participated in one of two detection tasks or a comparison ta
