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.

INDUSTRIALIZATION AS A SELF-FULFILLING PROPHECY: THE ROLE OF EXPECTATIONS IN DEVELOPMENT

A self-fulfilling prophecy (SFP) occurs when the expectation of an event induces the behavior that increases the likelihood of the event's occurrence. Work organizations can be more or less effective as a result of SFP effects, whether naturally-occurring or deliberately induced by managers or consultants. Evidence for SFP at the individual level and at the collective level in work organizations is reviewed, including the Pygmalion, Galatea, Golem, and Messiah effects. Next, the SFP concept is extended beyond the single organization to the industrialization process at the national level. This leads to the novel hypothesis that, to the extent that persons in a developing nation expect industrialization to progress rapidly and successfully, the development process is facilitated. Several examples of SFP on Israel's path to industrialization are described, and emulation of these examples by other newly industrialized countries is proposed.     

The clinical inference process and the role of theory

Perhaps the most challenging and creative aspect of clinical testing is the clinical inference process, the sequential steps the examiner takes in transforming the raw test data into a clinically relevant testing report. Unfortunately, this part of the testing process has received little attention in the testing literature. In this article, the specific steps in the inferential process are outlined. In addition, the ways in which theory enter into the inferential process are also discussed.
