Visually perceived eye level with reversible pitch stimuli: implications for the great circle and implicit surface models

Visually perceived eye level (VPEL) and perceived pitch were measured while subjects viewed two sets of stimuli that were either upright or pitched top-toward or top-away from them. The first set of stimuli, a pair of vertical lines viewed at various angles of pitch, caused systematic changes in perceived pitch and upward and downward VPEL shifts for the top-toward and top-away pitches, respectively. Neither the perceived pitch nor the VPEL measures with these stimuli differed between monocular and binocular viewing. The second set of stimuli was constructed so that, when viewed at the appropriate pitch angle, the projected orientations of the lines in the retinal image of each stimulus were similar to those generated by a pair of vertical lines pitched by a lesser amount in the opposite direction. When viewed monocularly, these stimuli appeared pitched in the direction opposite their physical pitch, yet produced VPEL shifts consistent with the direction of their physical pitch. These results clearly demonstrate a dissociation between perceived pitch and VPEL. The same stimuli, when viewed binocularly, appeared pitched in the direction of their physical pitch and caused VPEL shifts indistinguishable from those obtained monocularly. The retinal image orientations of these stimuli, however, corresponded to those of vertical line stimuli pitched in the opposite direction. This finding is therefore consistent with the hypothesis that VPEL and perceived pitch are processed independently, but inconsistent with the specific version of this hypothesis which states that differences in VPEL are determined solely on the basis of the orientation of lines in the retinal image.

Work–Family Conflict and Turnover Intentions Among Scientists and Engineers Working in R&D

Purpose  In this study we evaluate competing models of the direct and indirect effects of work interference with family (WIF) and family interference with work (FIW) on two turnover intentions relevant to scientists and engineers: (i) leaving R&D for non-R&D work within the same organization and (ii) leaving one’s organization for another one. Design/methodology/approach  A cross-sectional design was used. Our sample consists of almost 500 scientists and engineers in dual-earner families and with dependent care responsibilities. Findings  We find some support for the domain-specific predictors-to-outcomes model: FIW indirectly (but not directly) increases intentions to change organization through work dissatisfaction. Contrary to expectations from the stress management model we find neither direct nor indirect relationships between WIF and turnover intentions. Implications  Our findings suggest that organizations that help employees manage the effects of FIW on work dissatisfaction may be able to reduce the turnover among their technical workforce. Originality/value  The study examines an overlooked outcome of work-family conflict: turnover intentions. In addition, it provides much needed attention to the implications of workfamily conflict for scientists and engineers, who have received little attention in the work-family conflict literature despite longstanding efforts to understand the relationship between marriage, parenthood, and productivity in these fields.

Reexamining the possible benefits of visual crowding: dissociating crowding from ensemble percepts

Peripheral objects and their features become indistinct when closely surrounding but nonoverlapping objects are present. Most models suggest that this phenomenon, called crowding, reflects limitations of visual processing, but an intriguing idea is that it may be, in part, adaptive. Specifically, the mechanism generating crowding may simultaneously facilitate ensemble representations of features, leaving meaningful information about clusters of objects. In two experiments, we tested whether visual crowding and the perception of ensemble features share a common mechanism. Observers judged the orientation of a crowded bar, or the ensemble orientation of all bars in the upper and lower visual fields. While crowding was predictably stronger in the upper relative to the lower visual field, the ensemble percept did not vary between the visual fields. Featural averaging within the crowded region does not always scale with the resolution limit defined by crowding, suggesting that dissociable processes contribute to visual crowding and ensemble percepts.     

The moderating influence of procedural fairness on the relationship between work-life conflict and organizational commitment

To help employees better manage work-life conflict, organizations have introduced various initiatives, which have met with mixed results. The present studies examined the utility of a procedurally based approach to understanding employees' reactions to work-life conflict. The authors examined whether the fairness of procedures used by organizational authorities to plan and implement decisions moderates the (inverse) relationship between work-life conflict and employees' organizational commitment. Three studies using different methodologies showed support for the moderating role played by procedural fairness. That is, the tendency for greater work-life conflict to lead to lower commitment was significantly less pronounced when procedural fairness was high rather than low. Theoretical contributions to the work-life conflict and organizational justice literatures are discussed, as are practical implications.
