Visual attention and perceptual grouping

Perceptual organization is thought to involve an analysis of bothtextural discontinuities andperceptual grouping. In earlier work, we found that textural discontinuities were detected normally even when visual attention was engaged elsewhere. Here we report how perceptual grouping is affected when visual attention is engaged by a concurrent visual task. To elicit perceptual grouping, we used the Gestalt demonstrations of grouping on the basis of proximity and of similarity. Four tasks were investigated, some requiring the observer to discriminate between horizontal and vertical grouping, and some requiring the observer to merely detect the presence or absence of grouping. Visual attention was engaged at the center of the display by a form identification task. The detection of a textural discontinuity served as a control task. Concurrent form identification conflicted with all four grouping tasks, resulting in a significant reduction of grouping performance in each case. No performance reduction was observed when either form identification or grouping discrimination was combined with the detection of a textural discontinuity. These results suggest that perceptual grouping and form identification compete for visual attention, whereas the detection of a textural discontinuity does not.     

Giving Credit Where Credit Is Due: A Case of No Sex Bias in Attribution1

This study examines the effects of informational cues on the attribution of success in a masculine task. Israeli managers (subjects) first evaluated the performance of a fictitious male/female manager and then attributed a cause to his/her success in attaining the managerial position. As predicted, performance evaluation affected the attribution and manager sex did not. An unexpected association between leadership style and attribution was found. Implications of these findings for female managers and for further research are considered.
