Physical health and social network characteristics as determinants of mental health across cultures

This study examines cross-cultural differences in the etiology of depression and anxiety, two common indicators of mental health problems. Using an ethnically diverse sample of 162 college students, we found that chronic physical symptoms and social network characteristics, particularly network quality, were predictive of both depression and anxiety, yet their effects were mediated by ethnicity. Multiple regression analyses showed that social network quality, compared to physical health, was a much stronger predictor of mental health in Caucasian students, whereas among students of Asian/Pacific descent, physical health was a much stronger predictor of mental health than the social network characteristics. The observed differences were particularly strong for anxiety, which was not significantly associated with physical health in Caucasian students or social network size and quality in the Asian/Pacific group. Theoretical and clinical implications of the results are discussed.

Local contour characteristics as determinants of pattern discrimination

Subjects were required to discriminate complex random polygons which had the same global shapes but differed in local contour characteristics. Discrimination was most often successful when local contour features comprised a few long line segments or when they were relatively complex. Local contour features of intermediate sized elements and intermediate complexity played a smaller role in discrimination. Presentation time and interstimulus interval effects, and their interaction were observed. A two-factor explanation was offered for the effect of the contour variable.     

Persuasive argumentation and social comparison as determinants of attitude polarization

Several of our studies indicate that persuasive-arguments theory by itself is an adequate explanation of polarization. Sanders and Baron (Journal of Experimental Social Psychology 1977, 13, 303–314) criticize this research. More generally, they contend that both argumentation and comparison are involved, “with persuasive arguments facilitating the shifts motivated by social comparison.” We feel that their critique is unconvincing. Relevant portions of the standard literature are reviewed to demonstrate that social comparison is neither a necessary nor sufficient condition for polarization. Finally, we speculate about how persuasive-arguments theory could be extended to argument-poor settings (e.g., Asch's line comparison situation).     

Accessibility and fit as determinants of the salience of social categorizations

The present article proposes a theoretical model of factors affecting the salience of social categorizations. The model is strongly related to the accessibility×fit formulation by Bruner (1957) and to Oakes' (1987) functional perspective on category salience. The results of an experimental series using the ‘Who said what?’ paradigm are presented, which examined several hypotheses derived from the model. In Study I it was shown that the salience of a social categorization with high chronic accessibility (sex categorization) was related to perceptions of issue relevance (normative fit) and intercategory differences (meta‐contrast ratio). Furthermore, in line with the salience model measures to increase the situational accessibility, (i.e. a priming procedure) of categorizations with low chronic accessibility (educational group and home town categorizations) failed to affect category salience as long as participants perceived no comparative and normative fit of these categorizations (Study II). Under conditions where comparative fit of these categorizations was perceived, however, the priming procedure successfully enhanced category salience (Studies II and III). Results are largely consistent with the hypotheses derived from the salience model and support Oakes' functional approach to category salience. Finally, the complex interrelation between situational accessibility and perceived fit will be discussed. Copyright © 1999 John Wiley & Sons, Ltd.     

Developmental and social determinants of religious social categorization

The purpose of this study was to assess developmental and social determinants of the age at which children become aware that the social environment can be marked by categorization into religious groups and that those groups are associated with different religious beliefs. The results show that middle childhood is a critical period for this religious social categorization. Moreover, social factors play a role in the development. Religious categorization is likely to appear sooner in children attending heterogeneous schools than in those at homogeneous schools, and children from the minority religious group in the country understand religious categorization earlier than children from the majority group. However, no relation was found between the age at which religious categorization was understood and parents' religious socialization practices. This study is of both theoretical and practical interest: It complements what is already known about gender, race, and ethnic categorization by integrating developmental and social frameworks, and it can serve as a guideline for educational programs.     

The actions of others as determinants of behavior in social trap situations

Three studies were conducted to determine the effects of observing the behaviors of others upon an individual's actions in a simulated social trap situation. In Experiment 1, it was found that merely having the opportunity to make comparative appraisals of the actions of others led to greater competition for a finite common resource than when subjects were physically isolated from one another. In Experiment 2, false feedback was given to subjects to determine if the actions of others alone were responsible for the deleterious effects of having the opportunity for comparative appraisal; it was found that subjects quickly conformed to the behavior pattern of the interacting others, regardless of whether the false feedback indicated that the other subjects were consuming more or less than no-treatment control subjects. Experiment 3 was conducted to determine the motivation of subjects reacting to the actions of others; differential predictions based upon a competition/relative outcome explanation and upon an information search explanation were made. The data were consistent with the information search explanation.     

Objective determinants of perceived social support

Objective characteristics of people's social networks were examined as determinants of the perceived availability of social support in two populations: elderly adults (n = 50) and mothers of 1-year-olds (n = 71). Number of network members and frequency of contact with network members, computed separately for kin and nonkin were examined as predictors of loneliness, overall social support, and the six components of social support proposed by Weiss (1974). Kin were found to be more effective providers than nonkin of some aspects of social support. Network characteristics were better predictors of perceived social support for the elderly than for the mothers, but a maximum of 30% of the variance in perceived social support was attributable to the objective network characteristics in either sample. It is recommended that future research on the determinants of perceived social support consider actual interpersonal behaviors, their contexts, and personality characteristics that affect the facilitation an interpretation of supportive behaviors.     

Rate and frequency as determinants of learning with complete and discrete list presentation

In Experiment 1, complete presentation of the study list produced better free recall learning than did the usual item-by-item (discrete) presentation. The difference was large and held for items occurring one, two, or three times within a list, whether items were spaced or massed, and for discrete presentation rates of 2, 4, and 6 sec/item. Experiment 2 replicated this superiority of complete over discrete presentation (equating total study time), and Experiment 3 extended the finding to paired associate learning. Experiments 2 and 3 indicated that multiple presentations of a list at fast rates were superior to a single presentation at a more standard rate and only slightly inferior to a single, complete presentation. Practical implications for instruction were pointed out, as were problems that certain of the results pose for theories that emphasize strategic (or at least extended) processing of items for encoding.     

Satisfaction with social support during crisis: intimacy and self-esteem as critical determinants

Satisfaction with social support was studied longitudinally in a group of 113 Israeli women following the outcome of both normal and medically complicated pregnancies. Greater intimacy with spouse and with friends were found to be related to greater satisfaction with support received during this crisis period. Intimate ties contributed to satisfaction with support independent of self-esteem, social network parameters, and type of pregnancy outcome. Social network parameters and pregnancy outcome were not found to be related to satisfaction with support. Among women low in self-esteem, greater intimacy with family was found to be related to lower satisfaction with support if the women lacked intimate ties with spouse or a friend. The findings were discussed in light of clinical and social psychological theories regarding reaction to aid.
