A social relations variance partitioning of dyadic behavior.

The authors investigate the relative importance of actor and interaction partner as determinants of dyadic behavior. Using the social relations model (D. A. Kenny, 1994a; D. A. Kenny & L. La Voie, 1984), the authors estimate the variance attributable to each determinant plus the reciprocity of behavioral responses from 7 studies. The authors find evidence for moderate behavioral consistency in a person's behavior across interaction partners, little or no evidence that people consistently engender the same behavioral response from others, and preliminary evidence of unique responding to particular partners. They also consider several methodological issues concerning behavioral measurement as well as the implications of the results for the study of accuracy.

Aging, dominance history, and social behavior in Java-monkeys (Macaca fascicularis)

The aim of this study was to investigate the influence of the dominance history of socially housed Java-monkeys on the aging process. In monkeys, social subordinance is generally associated with elevated levels of cortisol, which, in turn, have been suggested to influence cognitive decline. As cognitive skills are necessary for successful social life, we investigated the effect of old age in relation to the dominance history of the animals on their social behavior by comparing old females with their younger daughters. Old age, especially in combination with a history of low rank, led to a withdrawal from social interactions with unfamiliar animals and to a decrease in amounts of aggression received. Still, however, old animals showed an increase in behaviors associated with arousal. A reduced ability to deal with complex social interactions, caused by a decline in information processing abilities, is suggested as an explanation for these results.     

Physical disability and social interaction: factors associated with low social contact and home confinement in disabled older women (The Women's Health and Aging Study)

OBJECTIVES: This study examines the association of disability and social interaction, measured as in-person contact with non-household members and home confinement, and identifies sociodemographic, socioeconomic, and health-related factors that modify this relationship. METHODS: Participants were 1,002 moderately to severely disabled community-dwelling women aged 65 and older from the Women's Health and Aging Study, identified by screening an age-stratified random sample of Medicare beneficiaries in Baltimore, Maryland. Logistic regression models were used to estimate the odds of low social interaction associated with disability and each independent modifier. RESULTS: In a typical week, 23% did not visit with anyone residing outside their households and 17% did not leave their homes. In addition to and independent of disability level, older age, not completing high school, having a driver in the home, hearing difficulties and incontinence were associated with low social contact; older age and African American race were related to home confinement. African American women living alone are especially vulnerable to home confinement. DISCUSSION: Physical disability is not necessarily socially disabling, as many of the most severely disabled in our study had at least daily social interaction. Improvements in social interaction appear possible through more effective management of certain health conditions and attention to potential sociocultural barriers.     

Accounting for changes in social support among married older adults: Insights from the MacArthur Studies of Successful Aging.

Using longitudinal, community-based data from the MacArthur Studies of Successful Aging, the authors examined determinants of changes in social support receipt among 439 married older adults. In general, social support increased over time, especially for those with many preexisting social ties, but those experiencing more psychological distress and cognitive dysfunction reported more negative encounters with others. Gender affected social support receipt: Men received emotional support primarily from their spouses, whereas women drew more heavily on their friends and relatives and children for emotional support. Discussion centers on the importance of social support provision to those with the greatest needs. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Brief report: Aging and functional spatial relations in comprehension and memory.

Previous research has suggested that, relative to younger adults, older adults devote a greater proportion of their discourse processing to the situation model level. The current experiment assessed whether this is due, in part, to a preserved ability to focus on functionally appropriate information. The focus here was on spatial relations. Both reading time and recognition data showed superior performance for functional over nonfunctional information, and this functional effect was similar in younger and older adults. This is consistent with the idea that older adults' ability to process information at the situation model level is relatively well preserved.

Social relationships, social support, and patterns of cognitive aging in healthy, high-functioning older adults: MacArthur Studies of Successful Aging.

This study examines the relationship of social ties and support to patterns of cognitive aging in the MacArthur Studies of Successful Aging (see L. F. Berkman et al., 1993), a cohort study of 1,189 initially high-functioning older adults. Baseline and longitudinal data provide information on initial levels as well as changes in cognitive performance over a 7.5-year period. Linear regression analyses revealed that participants receiving more emotional support had better baseline performance, as did those who were unmarried and those reporting greater conflict with network members. Greater baseline emotional support was also a significant predictor of better cognitive function at the 7.5-year follow-up, controlling for baseline cognitive function and known sociodemographic, behavioral, psychological, and health status predictors of cognitive aging. The findings suggest the potential value of further research on the role of the social environment in protecting against cognitive declines at older ages.

Self-efficacy beliefs and change in cognitive performance: MacArthur studies on Successful Aging.

Data from a cohort of relatively high functioning, older men and women were used to test the hypothesis that stronger self-efficacy beliefs predict better maintenance of cognitive performance. Structural equation modeling revealed that stronger baseline instrumental efficacy beliefs predicted better verbal memory performance at follow-up among men but not among women, controlling for baseline verbal memory score and sociodemographic and health status characteristics. For both men and women there were no significant associations between either type of self-efficacy beliefs and measures of nonverbal memory, abstraction, or spatial ability. Consistent with previous research showing relationships between baseline cognitive performance and change in self-efficacy beliefs, better abstraction ability was also predictive of increases in instrumental efficacy beliefs among the men.

Accuracy in interpersonal perception: A social relations analysis.

For the past 30 years, the study of accuracy in person perception has been a neglected topic in social and personality psychology. Research in this area was stopped by a critique of global accuracy scores by Cronbach and Gage. They argued that accuracy should be measured in terms of components. Currently, interest in the topic of accuracy is rekindling. This interest is motivated, in part, by a reaction to the bias literature. We argue that modern accuracy research should (a) focus on measuring when and how people are accurate and not on who is accurate, (b) use each person as both judge and target, and (c) partition accuracy into components. The social relations model (Kenny & La Voie, 1984) can be used as a paradigm to meet these requirements. According to this model, there are four types of accuracy, only two of which are generally conceptually interesting. The first, called individual accuracy, measures the degree to which people's judgments of an individual correspond to how that individual tends to behave across interaction partners. The second, called dyadic accuracy, measures the degree to which people can uniquely judge how a specific individual will behave with them. We present an example that shows high levels of individual accuracy and lower levels of dyadic accuracy. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Government-science relations: The physical and social sciences compared.

A comparison of federal funding of the sciences shows a disproportionate distribution of funds, with the social sciences receiving the poorest treatment. Factors contributing to this may include a difference in the relative rate of research activity between the physical and social sciences and the less advanced state of practical application of the social sciences. The social sciences also may differ in being directly connected to the quality of life, moral and spiritual values, human freedom, and the social fabric. This view has resulted in controversy and led to government restrictions. Such a view, however, is a misperception of the difference between social and physical sciences. In all, the sciences are more similar than dissimilar. With increased support and understanding, the social sciences will make increasing contributions to the national capacity for social change in the future.

Aging and social satisfaction: Offsetting positive and negative effects.

Social satisfaction in late adulthood originates from competing sources. Older adults tend to be more positive and less negative than younger adults, but social contact and working memory often decrease with age, both of which might limit older adults' social functioning. In the current study of younger and older adults, these socially facilitative vs. socially debilitative changes were found to underlie stasis in social satisfaction. These findings show that the lack of an overall effect for age can mask competing changes in social functioning in late adulthood, as the sources of social satisfaction might change even if the outcome does not.

Changes in Functional Status Among Older Adults in Japan: Successful and Usual Aging.

This research aimed to chart the trajectories of functional status in old age in Japan and to assess how self-rated health and cognitive functioning differentiate these trajectories and account for interpersonal differences. Data came from a 5-wave panel study of a national sample of 2,200 Japanese older adults between 1987 and 1999. The sample as a whole showed an accelerated increase in functional limitations with age, approximated by a quadratic function. More important, 3 major trajectories of functional change were identified: (a) minimal functional decrement, (b) early onset of functional impairment, and (c) late onset of functional impairment. These findings may serve as useful benchmarks for observations derived from other developed nations. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Sex differences in social behavior: comparing social role theory and evolutionary psychology

In rats, copper deficiency leads to low copper metalloenzyme activity, high serum cholesterol, and cardiovascular lesions. In humans, moderately low copper intake may be common, but the consequences remain largely uncertain. The present study examined the effects of copper supplementation (2 mg/d for 4 weeks in a copper/placebo crossover design) in 20 adult men with moderately high plasma cholesterol. End-point measurements were three copper enzyme activities, erythrocyte superoxide dismutase (SOD), plasma ceruloplasmin (Cp), and plasma diamine oxidase (DAO), and three parameters related to the risk of cardiovascular disease (CVD), plasma cholesterol, plasma lipoprotein (a) [Lp(a)], and lag times for very-low-density lipoprotein (VLDL) and low-density lipoprotein (LDL) oxidation in vitro. Although copper had no significant effects on any parameter for the entire study group, it did significantly increase two enzyme activities (SOD and DAO), as well as lipoprotein oxidation lag times, in 10 subjects in the lower half of a median split for precopper values. Thus, copper supplementation appeared to influence some types of measurements in subjects beginning with less than median values.     

Managed care in workers' compensation: analysis of cost drivers and vendor selection

1. Managed care for employee benefits provides a model of cost containment for workers' compensation; however, significant differences must be understood. 2. Purchasers of managed care services must perform an internal assessment to determine the cost drivers for workers' compensation. Managed care does not address all cost drivers. 3. A model for evaluating managed care vendors places them on a continuum of risk, similar to insurance risk, where a variety of cost containment strategies may be used together. 4. By reviewing seven key aspects of a managed care vendor, a purchaser can rate the vendor's ability to meet their needs.     

Power estimation in social relations analyses.

This article is intended for investigators interested in applying the Social Relations Model (SRM) to the study of dyadic processes. On the basis of theory and simulation, the authors provide practical advice concerning optimal number of persons per research group, number of research groups, type of research design, and significance testing method. Power depends more on group size than on number of groups. Power also is greater with the round-robin design than with the block design and greater with an asymptotic test of significance than with the test usually used. The authors discuss the effect of skew on theoretical power. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Interpersonal perception in group therapy: A social relations analysis.

Although group therapists have emphasized the importance of interpersonal perception and feedback during therapy, there has been little systematic research on how group members form impressions of one another. D. J. Kiesler's (see record 1983-30243-001) interpersonal circle provided a framework for studying interpersonal perception and relations. 27 women and 18 men from 9 time-limited therapy groups reported their impressions of their fellow group members using the Impact Message Inventory, and they also completed 2 self-report scales. A social relations analysis of this data indicated that Ss' perceptions included both assimilation and consensus. There was also a relationship between how Ss saw themselves before therapy and how they were seen by other group members. The results demonstrated the utility of the social relations model for group therapy research and provided modest support for Kiesler's interpersonal circle.

Ethnic relations in rental housing: A social psychological approach.

Conducted interviews with a random sample of 59 French Quebecer landlords within a section of Montreal to explore the social psychological bases for discrimination in rental housing. Evidence that Social Identity factors related to the overwhelming preference for in-group tenants was obtained. When landlords were asked to focus on 4 out-groups (Haitians, Italians, Asiatics, and English Quebecers), factors subsumed under Realistic Conflict theory also contributed strongly to the variation in willingness to rent to some out-groups as opposed to others. Overall, results suggest a dissociation model where Social Identity and Realistic Conflict factors operate independently and additively in relations with out-group tenants.

Intergroup relations and South African social psychology: Historical ties.

Seven research themes in South African social psychology are identified and sketched historically: the use of psychological tests to make comparisons between groups; attitudes; authoritarianism; the "marginal personality"; the contact hypothesis; a state-sponsored investigation into intergroup relations; and social identity theory. It is argued that the development of these themes has to be examined in conjunction with changes in the political discourse in South Africa about "race."

The effects of group cohesiveness on social loafing and social compensation.

Individuals often engage in social loafing, exerting less effort on collective rather than individual tasks. Two experiments tested the hypothesis that social loafing can be reduced or eliminated when individuals work in cohesive rather than noncohesive groups. In Experiment 1, secretarial students typed both individually and collectively in simulated word-processing pools composed of either friends or strangers. In Experiment 2, dyads composed of either friends or strangers worked either coactively or collectively on an idea-generation task. Both studies supported the group cohesiveness hypothesis. Experiment 2 also suggested that individuals tend to engage in social compensation when working with coworkers who are low in ability. These findings are discussed in relation to S. J. Karau and K. D. Williams's (1993) Collective Effort Model. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Agreement and accuracy in children's interpersonal perception: A social relations analysis.

Agreement and accuracy in children's interpersonal perceptions during middle childhood were studied in the school environment. Sociocultural and ecological theories led to the prediction that, in middle childhood, peers' interpersonal perceptions would show high levels of agreement with those of teachers and would be accurate. A social relations analysis of data from a 3-year, cross-sequential study revealed that throughout middle childhood, peer perceptions of cognitive ability, observable behavior and characteristics, popularity, and affect correlated reliably with teacher perceptions. In addition, peer and teacher perceptions of targets' cognitive ability correlated with standardized test scores. Self-other agreement lagged behind teacher-peer agreement. The conceptual and statistical advantages of the social relations analysis of children's interpersonal perceptions were also considered. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
