Abstract
An experiment with a rapid serial visual presentation (RSVP) paradigm and target-specified and target-categorized conditions is reported. Among other improvements to the design, a response time measure was included as an index of the time needed to detect the target’s key feature. Typical patterns of intrusion were found: posttarget predominance in the target-specified condition and symmetry in the target-categorized condition. Reaction times (RTs) do not show the strictly increasing function predicted from simple parallel models; the shortest RTs were associated with hits and their functions were similar for the two experimental conditions. The results are discussed within the context of parallel views, and an account for the differences between target-specified and target-categorized conditions is proposed.
