Between-task crosstalk has been discussed as an important source for dual-task costs. In this study, the authors examine concurrently performed saccades and manual responses as a means of studying the role of response-code conflict between 2 tasks. In Experiment 1, participants responded to an imperative auditory stimulus with a left or a right…

The significance of spatial factors on an initial segmentation and an active attentional phase was demonstrated by briefly exposing spatial configurations of elements, and then asking the subjects to reproduce the patterns or to search them for a target letter. The stimulus displays consisted of small o's forming different spatial configurations,…

The visual scanning of redundant and random spatial configurations of two-digit numbers was investigated in a target recognition task. The experimental technique involved a brief exposure of a probe (a two-digit number) at the center of the visual field, followed by a spatial pattern of 16 two-digit numbers which included the matching target in…
