Field dependence and lateralization of verbal and configurational processing.

With tachistoscopic presentation, relatively field-dependent 18- to 30-year-old males were found to show a significant right-visual-field advantage in reaction-time in a letter discrimination task, while relatively field-dependent subjects did not show a significant hemifield difference. In a second study, relatively field-independent 18- to 30-year-old males again showed a significant right-visual-field superiority in reaction time to letter discrimination, and in addition showed a significant left-visual-field superiority in tachistoscopic face discrimination, while relatively field-dependent subjects showed no significant hemifield difference on either task. The results are interpreted as indicating a link between Witkin's concept of psychological differentiation and differentiation at the neural level, as manifested by specialization of function of the cerebral hemispheres.

Field independence and laterality in the perception of faces.

For a sample of 28 college males the degree of left visual-field bias in the perception of faces correlated .45 (p less than .01) with extent of field-independent performance, as assessed by a composite score based on the Embedded-Figures Test, the Rod-and-Frame Test, and ratings on the Articulation-of-Body-Concept Scale. In a second study with 16 female and 10 male college subjects using the Group Embedded-Figures Test, field-independent subjects again showed greater left visual-field lateralization of face perception (r = .43, p less than .05). Based on Witkin's view of field independence as a manifestation of psychological differentiation, possible links between extent of differentiation at the psychological and neurophysiological levels are suggested.

Field dependence and the role of visual frameworks in the perception of size.

The extent to which apparent size is relationally determined has been studied by Rock and Ebenholtz and by Wenderoth, who came to widely differing conclusions as to the magnitude of this phenomenon. In both studies, a large range of individual differences was observed. In the present study, an attempt was made to account for variations in the influence of visual contexts on the perception of size by relating them to the cognitive style dimension of field dependence/independence. In two situations, relativelyfield-dependent observers made size judgments which were influenced by a frame surrounding the target figure, while relatively field-independent observers made size judgments which were influenced by a frame surrounding the target figure, while relatively field-independent observers tended to be less influenced by the frame, making their judgments approximate the retinal size of the target. The results suggest that assessment of the magnitude of the relational determination of apparent size must consider the cognitive style of the observers as well as situational variations.

Psychological differentiation as a factor in conflict resolution.

Previous studies have shown that persons matched in level of differentiation are likely to develop greater interpersonal attraction in the course of an interaction than are mismatched persons. These studies were all conducted in situations where the interacting persons were working toward a common goal. To test the hypothesis that situational variables may moderate match-mismatch effects, the present study investigated these affects when the interacting persons were in conflict. Based on their performance in tests of field dependence-independence, subjects were selected as relatively high or relatively low in level of differentiation. Three kinds of dyads were composed-high-differentiation/high-differentiation, low-differentiation/low-differentiation, and high-differentiation/low-differentiation--and their task was to reconcile conflict on an issue about which they were known to disagree. It was predicted that because of the more accommodating quality of low-differentiation persons, dyads including one or two such subjects would more often reconcile their disagreements and show greater interpersonal attraction than would dyads consisting of two high-differentiation subjects. Both predictions were confirmed, supporting the hypothesis that the outcome of match or mismatch is mediated by situational variables.
