Covariation assessment in rank order data

Two experiments were conducted to investigate how individuals assess covariation with rank order data. In both studies, subjects were given sets of rank order data, each set consisting of ten items ranked on two characteristics, and were asked to estimate the degree of relationship for each set. Contrary to previous research, subjects' estimates of covariation in this task were quite sensitive to actual levels of correlation in the data and remained unaffected by simple variations in the way rank order data were presented. More importantly, it appeared that this sensitivity to covariation was due likely to the use of a simple heuristic referred to here as the total discrepancy heuristic. These findings are discussed in terms of the availability of simple heuristics in rank-ordered versus other types of data and the consequences of using such heuristics in decision-making contexts.     

A comparison of methods for calculating a severe discrepancy

Given the substantial rise in the number of students identified as learning-disabled, increasing attention has centered on methods for determining a severe discrepancy between ability and achievement. Using scores from 86 learning disabilities referrals, we compared four such methods (a z-score discrepancy, an estimated true score discrepancy, an unadjusted regression procedure, and an adjusted regression procedure). Each student was evaluated with the WISC-R, PIAT, and K-ABC. A high degree of agreement was found between z-score and estimated true score difference approaches. Less agreement was found between the unadjusted regression procedure and the other methods. It was concluded that the four methods cannot be used interchangeably in the calculation of severe discrepancies. Of the four methods that were analyzed, the unadjusted regression procedure selected the smallest percentage of students.     

Decision Making Versus Decision Implementation: An Action Control Approach to Exercise Adoption and Adherence1

Two studies were conducted, one involving adoption of an exercise program and the other involving adherence to an aerobics exercise program. Consistent with action control theory, it was hypothesized that (a) subjective expected utility theory would predict exercise intentions but not exercise behavior in each study; (b) exercise adoption (Study 1) and attendance at an aerobics class (Study 2) would be predictable from the intentions regarding these behaviors expressed by action-oriented but not state-oriented subjects; and (c) subjects who had engaged in planning in regard to exercising would be more likely to adopt an exercise program (Study 1) and would exercise more frequently (Study 2). The findings provide some support for all three hypotheses. Implications of this research are discussed in regard to the distinction between decision making and decision implementation or action control; the relative usefulness of an action-control versus an expectancy-value approach for behavior involving complex decision implementation over a long period of time; the value of action orientation as a moderator of intention-behavior relationships; and the role of planning in exercise behavior.     

Community-based services and resources: The significance of choice and diversity

Conclusions We are reminded by the growth of consumer-run approaches of the value of diversity and individual choice in community support of persons with severe mental illness. These ideas are evident in the alternative approaches that have been developed to serve persons who have not been reached by more traditional services. The ACT program, described by Bond et al. (1990), is an example of a service approach designed to be responsive to individuals' day-to-day needs as they define them. Continued development of this type of alternative service should be encouraged.Persons coping with severe mental illness benefit from a variety of community supports and resources. Strategies that encourage consumer involvement, ownership, and control help to provide diversity of services and to empower the consumer. Our efforts, as professionals, to provide community services can be enhanced by (a) supporting diversity of service and resource options, both inside and outside of the professional mental health system; (b) developing services that are responsive to individuals needs as they define them; and (c) facilitating the process of consumer choice in selecting resources options.The author expresses thanks to Marc A.

Nontraditional sex role aspirations,gender identity conflict,and disordered eating among college women

Many studies point directly to the role played by sex roles and indirectly to the role played by gender identity in the onset of disordered eating. In this study, women who report adhering to nontraditional sex role aspirations are almost twice as likely as other women to report purging or frequent bingeing. Women who exhibit gender identity conflict by drawing a male or androgynous figure on the Draw-A-Person Test or by reporting a pattern of wishing they had been born a male are more likely than other women to report purging or frequent bingeing. The results are consonant with a hypothesis regarding the etiology of disordered eating that implicates gender identity conflicts among women, particularly women who exhibit nontraditional sex role aspirations.     

The role of the hemispheres in closed loop movements

The purpose of these experiments was to determine if the two hemispheres play different roles in controlling closed loop movements. Subjects were asked to move to a narrow or wide target in the left or right hemispace. Reaction time (RT) was faster for the left arm of normals, only in the right hemispace, but there were no differences between arms in movement execution. Right but not left hemisphere stroke (CVA) patients showed longer RTs for the contralateral but not ipsilateral arm. The right CVA group's ipsilateral movement, especially to narrow targets was less accurate. The left CVA group's RT did not benefit from advanced information, but ipsilateral movement execution was normal. These results were discussed in terms of inter- as well as intrahemispheric control of programming and execution of closed loop movements.     

Who are your Neighbors? Neighbor Relationships and Subjective Well-Being in Japan

Supportive relationships with neighbors have been shown to positively predict indicators of subjective well-being. Using data from the 2010 Japanese General Social Survey, we examine how neighbor relationships predict subjective well-being. Japan presents an interesting case to examine this question when considering its highly institutionalized neighborhood associations. We find that controlling for the safety and amenity aspects of the neighborhood environment, supportive neighbor relationships significantly increase men and women’s life satisfaction, but such relationships have a significant positive effect only on men’s happiness. The effects of neighborhood relationships on life satisfaction and happiness are significantly larger for men. Moreover, we find that the social and safety aspects of the neighborhood reinforce each other to increase life satisfaction also only for men. Implications of the gendered pattern of these results are discussed for future research on the association between neighbor relationships and subjective well-being in Japan and beyond.

     

Academic Socialization Among Latino Families: Exploring the Compensatory Role of Cultural Processes

This study examines the relation of parent educational expectations, cultural socialization, and familism with academic adjustment among 150 Latino parent–adolescent dyads (81% Mexican origin; 79% were mothers). Adolescents (53% girls) responded to measures of school engagement, educational utility, parental educational expectations, cultural socialization, and familism. Results suggest that, after accounting for parents’ reported educational attainment, adolescents’ perceptions of academic and cultural socialization messages and their own endorsement of familism were uniquely related to school engagement; only parental educational expectations were uniquely related to beliefs about the utility of education. Cultural and academic socialization may thus complement each other.     

Family Conflict Moderates the Relation Between Negative Mood and Youth Internalizing and Externalizing Symptoms

Higher negative (or lower positive) mood is associated with internalizing and externalizing problems among some, but not all youth, suggesting that contextual factors may influence these temperament-symptom relations. Family conflict also is associated with internalizing and externalizing problems, although it is unclear whether family conflict influences the relation between negative mood and symptoms. To address this gap, we examined whether family conflict moderates the relations between temperamental negative mood and internalizing and externalizing symptoms. Participants were 775 youth (69?% male, 76?% Caucasian). Mothers and youth completed questionnaires when youth were ages 10–12 (time 1) and 12–14 (time 2). When exposed to higher family conflict at time 1, children higher in negative mood experienced higher time 2 internalizing and externalizing problems than children lower in negative mood. When exposed to lower family conflict, children’s internalizing and externalizing symptom levels were similar regardless of their levels of negative mood. Findings suggest that interventions aimed at reducing youth’s risk for internalizing and externalizing symptoms should address conflictual interactions within the larger family system, particularly among youth with higher negative mood.
