Temporal integration in face perception: evidence of configural processing of temporally separated face parts

Temporal integration is the process by which temporally separated visual components are combined into a unified representation. Although this process has been studied in object recognition, little is known about temporal integration in face perception and recognition. In the present study, the authors investigated the characteristics and time boundaries of facial temporal integration. Whole faces of nonfamous and famous people were segmented horizontally into 3 parts and presented in sequence, with varying interval lengths between parts. Inversion and misalignment effects were found at short intervals (0-200 ms). Moreover, their magnitude was comparable to those found with whole-face presentations. These effects were eliminated, or substantially reduced, when the delay interval was 700 ms. Order of parts presentation did not influence the pattern of inversion effects obtained within each temporal delay condition. These results demonstrate that temporal integration of faces occurs in a temporary and limited visual buffer. Moreover, they indicate that only integrated faces can undergo configural processing.

Psychometric properties of eating disorder instruments in Black and White young women: internal consistency, temporal stability, and validity

Most of the major instruments in the eating disorder field have documented psychometric support only in predominantly White samples. The current study examined the internal consistency, temporal stability, and convergent and discriminant validity of a variety of eating disorder measures in Black (n = 97) and White (n = 179) female undergraduates. Internal consistency coefficients were good (>.76) for all measures for both groups. Temporal stability across 5 months was also adequate in both groups, but with evidence for dietary restraint and subjective binge eating being less stable in Black women (e.g., for the Restraint subscale of the Three-Factor Eating Questionnaire [TFEQ], r = .63 for Black women and r = .82 for White women). Scores on the bulimic symptoms and dietary restraint instruments converged and diverged in a theoretically consistent pattern. Findings suggest these eating disorder measures are reliable (internally consistent; temporally stable over 5 months) and that the bulimic symptom measures of the Bulimia Test-Revised, the Bulimia subscale of the Eating Disorder Inventory, and the dietary restraint measures from the Eating Disorder Examination-Questionnaire and TFEQ demonstrate convergent and discriminant validity in Black college women.     

The socioecological model of procommunity action: the benefits of residential stability

The authors conducted 3 studies to test a socioecological model of procommunity action. Study 1 showed that residents of stable communities purchased a "critical habitat" license plate to support preservation of the environment in their home state more often than did residents of mobile communities. Study 2 demonstrated that home game baseball attendance was less dependent on the team's record in stable cities than in mobile cities. Study 3, an experiment, showed that residential stability had a causal impact on procommunity behavior. Moreover, the effect of stability was partially mediated by identification with the "community." Together, these studies indicate that residential stability can lead to stronger identification with one's community, which, in turn, leads to more procommunity behaviors.     

A model of stress and coping and their influence on individual and organizational outcomes

A model of coping with stress is proposed in which coping mediates the relationship among organizational stressors and personal characteristics, and job-related strains and organizational outcomes. Study results, based on a sample of professional salespeople, provide overall support for most of the hypothesized relationships among work-related stressors, personal characteristics, and coping styles. Findings also support the influence of emotion-focused coping on the psychological outcomes of emotional exhaustion and job-induced anxiety; which in turn are found to influence job satisfaction and intention to withdraw. While problem-focused coping had no effect on job-induced anxiety, problem-focused coping did effect emotional exhaustion, which in turn influences job satisfaction and intention to withdraw. Minor differences were found when the proposed model was applied to saleswomen versus salesmen. Overall, however, the model was robust across both genders.     

The control of contextual extinction effects during a fear-incubation procedure

The role of contextual (apparatus) cues upon baseline control groups in a fear-incubation procedure was examined. Using a suppression-of-licking measure, it was determined that infrahuman demonstrations of fear incubation have not clearly demonstrated an enhanced fear response (fear incubation) following brief unreinforced CS exposures. Adequate control for background apparatus exposures for the baseline-control group indicated that a facilitation of extinction for the no-CS-exposure group may, in fact, account for group differences. Results were interpreted within the context of existing theoretical models of fear extinction and incubation.
