Matters of the variable heart: respiratory sinus arrhythmia response to marital interaction and associations with marital quality

Maintenance of relationship quality requires self-regulation of emotion and social behavior, and women often display greater effort in this regard than do men. Furthermore, such efforts can deplete the limited capacity for self-regulation. In recent models of self-regulation, resting level of respiratory sinus arrhythmia, quantified as high-frequency heart rate variability (HF-HRV), is an indicator of self-regulatory capacity, whereas transient increases in HF-HRV reflect self-regulatory effort. To test these hypotheses in marriage, 114 young couples completed measures of marital quality and a positive, neutral, or negative initial marital task, preceded and followed by resting baseline assessments of HF-HRV. Couples then discussed a current marital disagreement. Resting HF-HRV was correlated with marital quality, suggesting that capacity for self-regulation is associated with adaptive functioning in close relationships. For women but not men, the negative initial task produced a decrease in resting HF-HRV. This effect was mediated by the husbands' negative affect response to the task and their ratings of wives as controlling and directive. When the subsequent disagreement discussion followed the negative initial task, women displayed increased HF-HRV during the discussion but a decrease when it followed the neutral or positive task. The valence of the initial task had no effect on men's HF-HRV during disagreement. Negative marital interactions can reduce women's resting HF-HRV, with potentially adverse health consequences. Women's reduced health benefit from marriage might reflect the depleting effects on self-regulatory capacity of their greater efforts to manage relationship quality.     

A note on a class of probability matching models

Probability matching is shown to be a property of a broad class of models of binary choice behavior.This note is based in part on a section of Feldman's doctoral dissertation submitted to the Graduate School of Industrial Administration, Carnegie Institute of Technology.     

Work Performance and the Achievement—Strivings and Impatience—Irritability Dimensions of Type A Behaviour

On propose dans cette étude un modfèle selon lequel les efforts en vue de la réussite et les dimensions impatience-irritabilité du comportement de type A prédisent directement et/ou indirectement la performance au travail. Dans un échantillon de 92 hommes et de 69 femmes (âge moyen: 30 ans), les efforts en vue de la réussite sont tenus de prédire la performance professionnelle directement et par l'intermédiaire de leur action positive sur la concentration. On suppose que l'impatience-irritabilité va détériorer la santé; et tout problème de santé devrait influencer négativement la concentration. On a recueilli, pour apprécier la performance au travail, à la fois des auto-évaluations et celles du contremaître. Une analyse taxinomique a fortement corroboré le modèle retenu bien que la liaison indirecte entre les efforts en vue de la réussite et les évaluations de la performance par le contremaître ne soit pas statistiquement significative.
In this study, a model is proposed whereby the achievement-strivings and impatience–irritability dimensions of Type A behaviour predict work performance directly and/or indirectly. In a sample of 92 males and 69 females ( M age = 30 years), achievement strivings are held to predict work performance directly and through their positive effects on concentration. impatience–irritability is predicted to negatively influence health; and any health problems are predicted to negatively influence concentration. Both self- and supervisor ratings of work performance were obtained. Path analyses provided strong support for the proposed model, although the direct link between achievement strivings and supervisor ratings of performance was not statistically significant.     

GENDER AND WORK HISTORY IN THE PLACEMENT AND PERCEPTIONS OF ELDER COMMUNITY VOLUNTEERS

This study explored factors that determine the types of volunteer jobs older adults are placed in, as well as factors that define the meaning of their roles. With a sample of 169 elder community volunteers (mean age, 73 years), we investigated the patterns of job perceptions of women and men in two types of volunteer positions: jobs that involved leadership and jobs that did not. A two-way MANOVA with gender and leadership as independent variables revealed that there was a significant interaction effect. When men are leaders, their sense of interpersonal feedback is higher than when they are non-leaders, but their sense of influence and autonomy is lower. Women in leadership jobs feel more influential and autonomous than their peers in non-leadership jobs. Subsequent analyses probing differences in job placement suggested that work history was a significant predictor of leadership jobs for men, but not for women. Correspondingly, men with prestigious preretirement work histories perceived their volunteer roles as less influential than men who had been in lower status jobs before retirement. Work history was not a predictor of job perception for women. These placement and perception issues are discussed within the context of an historical perspective on paid work, with special emphasis on gender.

A Rich Landscape of Affordances

Mark (1987) reported that observers, whose sitting capabilities had been altered by having them wear 10-cm blocks, were able to discover their own maximum height of a surface that afforded sitting on (SHmax), in the absence of an opportunity to practice sitting while wearing blocks. The current investigation attempted to identify conditions under which returning of an observer's SHmax, occurred. Returning of SH@, judgments readily occurred when observers were able to locomote between trials (Experiment 1), and rotate their heads, lean forward and to the side while making their judgments (Experiments I-2). However, they were unable to retune their SHmax, when the viewing conditions restricted all but the most basic actions (Experiments 3-5). Observers' actions during and between trials also were critical to the accuracy of their judgments when they did not wear the blocks. Overall, these findings strongly implicate observers' own activities as crucial for revealing information about their own S@ under both conditions when they are and are not familiar with their own sitting capabilities. Experiment 6 bolstered this conclusion by showing that prior practice with the act of sitting was not sufficient to enable observers to retune their own SHmax, (block condition) or to perceive their own SHmax under familiar circumstances (no block).     

The Better Beginnings,Better Futures Project: Long‐term Parent,Family, and Community Outcomes of a Universal,Comprehensive, Community‐Based Prevention Approach for Primary School Children and their Families

Better Beginnings, Better Futures is a large‐scale, multi‐year, longitudinal research‐demonstration project designed to reduce children's problems, promote healthy child development, and enhance family and community environments in three economically disadvantaged communities in the province of Ontario, Canada. The initial intervention was implemented from 1993 to 1997 and focused on families with children from 4 to 8 years of age in their first 4 years of schooling (from Junior Kindergarten to Grade 2). This study examined the long‐term parent, family and community programme outcomes, 15 years after the start of the intervention, when the young people who had participated in the intervention as young children were 18 to 19 years of age. Comparison of intervention communities with matched non‐intervention communities showed a mix of outcomes. Although few significant differences between intervention and comparison communities were found with regard to parents' health and family outcomes, there was evidence that parents in the intervention communities were engaging in fewer risk behaviours, had lower levels of depression and had more community involvement than parents in the comparison communities. These results suggest that the intervention did have some positive long‐term effects on youths' parents and on their community environments. Results are discussed with respect to the importance of considering family and neighbourhood contexts in the development and evaluation of prevention programmes.

S-R correspondence effects of irrelevant visual affordance: Time course and specificity of response activation

It has been suggested that representations for action, elicited by an object's visual affordance, serve to potentiate motor components (such as a specific hand) to respond to the most afforded action. In three experiments, participants performed speeded left-right button press responses to an imperative target superimposed onto a prime image of an object suggesting a visual affordance oriented to left or right visual space. The time course of response activation was measured by varying the onset time between the prime and target. Long-lasting and gradually developing correspondence effects were found between the suggested affordance of the prime and the side of response, with little effect of response modality (hands uncrossed, hands crossed, or foot response). We conclude that visual affordances can evoke an abstract spatial response code, potentiating a wide variety of lateralized responses corresponding with the affordance.
