Effects of Spatial Configuration on Visual Attention Processes. Umea Psychological Reports No. 154.
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, varying in density and exposed by means of a two-channel tachistoscope. Judgmental classification of reproduced patterns revealed that the segmentation phase is affected by the form of the functional field of view, retinal position, spatial redundancy, and density. The pattern of the attended positions in the search phase reflected the impact of certain specific properties of the spatial configurations and the task requirements. The results lend support to the validity of the suggested differences in the modes of processing. Data tables and four references are included in this report. (Author)
