Social influence, marriage, and the heart: cardiovascular consequences of interpersonal control in husbands and wives.

Human and experimental animal research suggests that social stress in general--and chronic, effortful attempts to exert social control in particular--may contribute to cardiovascular disease. We examined the effects of exerting social influence or control on cardiovascular responses in married couples. Compared to husbands discussing a problem with their wives, husbands attempting to influence or persuade their wives displayed larger increases in systolic blood pressure (SBP) before and during the discussion. Furthermore, these physiological effects were accompanied by increases in anger and a more hostile and coldly assertive interpersonal style. Although wives who engaged in social influence attempts displayed generally similar behavior, they did not show the elevated SBP response or anger. We discuss the results in terms of the social context of cardiovascular reactivity and potential marital factors in cardiovascular health.     

Defining, Measuring, and Comparing Organisational Cultures

La littérature portant sur la culture des organisations souffre d'un manque manifeste d'enquêtes extensives débouchant sur des études comparatives. Afin de rendre plus comparables les cultures organisationnelles, nous proposons une définition et une série de dimensions. La culture organisationnelle renverrait aux perceptions communes des pratiques de travail dans le cadre des unités constitutives des organisations. A l'examen d'études empiriques, les cinq dimensions suivantes nous sont apparues: autonomie, orientation externe, coordination interdépartementale, orientation vers les ressources humaines et orientation vers le développement. L'utilisation de cette définition et de ces dimensions générales devrait faciliter la comparaison des cultures organisationnelles et l'accumulation de résultats.
Within the body of organisation culture literature, there is a conspicuous absence of large-scale studies reporting on comparative studies. In order to increase comparability of organisational cultures we propose a definition and a set of dimensions. Organisational culture is defined as shared perceptions of organisational work practices within organisational units. On the basis of empirical studies we discerned the following five dimensions: autonomy, external orientation, interdepartmental coordination, human resource orientation, and improvement orientation. Use of this definition and a set of such generic dimensions would facilitate the comparison of organisational cultures and the accumulation of research findings.     

Aging and memory for expected and unexpected objects in real-world settings.

Adult age differences in the consistency effect were examined in 3 experiments. The consistency effect refers to items inconsistent with expectations being better remembered than items consistent with expectations. Younger and older adults walked into an office room and viewed objects that varied in their consistency with expectation. Immediate and delayed recognition tests on item information (i.e., distractors were defined by their semantic identity) revealed that both age groups recognized unexpected items better than expected items. However, when recognition of token information was requested (i.e., distractors were defined by their physical appearance), younger adults, in contrast to older adults, exhibited consistency effects. Also, under divided attention, young adults revealed the same pattern of data as did elderly adults under full attention. The results are discussed in terms of capacity-related differences in distinctive encoding.     

Experiencing Range in an Electric Vehicle: Understanding Psychological Barriers

Range of electric vehicles (EVs) has long been considered a major barrier in acceptance of electric mobility. We examined the nature of how range is experienced in an EV and whether variables from other adaptation contexts, notably stress, have explanatory power for inter‐individual differences in what we term comfortable range. Forty EVs were leased to a sample of users for a 6‐month field study. Qualitative and quantitative analyses of range experiences were performed, including regression analyses to examine the role of stress‐buffering personality traits and coping skills in comfortable range. Users appraised range as a resource to which they could successfully adapt and that satisfied most of their daily mobility needs. However, indicators were found that suggested suboptimal range utilisation. Stress‐buffering personality traits (control beliefs, ambiguity tolerance) and coping skills (subjective range competence, daily range practice) were found to play a substantial role in comfortable range. Hence, it may be possible to overcome perceived range barriers with the assistance of psychological interventions such as information, training, and interface design. Providing drivers with a reliable usable range may be more important than enhancing maximal range in an electric mobility system.     

Evidence for disproportionate dual-task costs in older adults for episodic but not semantic memory

Previous research demonstrates that older adults are poor at dual tasking, but there is less agreement on whether their decrement is worse than that predicted from single-task performance. This study investigated whether task domain moderates dual-task costs in old age. In two experiments, young and older adults retrieved either previously learned associates (episodic retrieval) or overlearned category members (semantic retrieval) under single or working-memory load conditions, using cued recall (Experiment 1) and recognition (Experiment 2) procedures. In both experiments the proportional costs of dual tasking were age invariant for semantic retrieval but were particularly marked for episodic retrieval, although the size of the age effect was reduced in recognition compared to cued recall. The data suggest that age effects in dual tasking may be domain specific.     

On the relation between feeling of knowing and lexical decision: persistent subthreshold activation or topic familiarity?

Experiment 1 replicated Yaniv and Meyer's (1987) finding that lexical decision and episodic recognition performance was better for words previously yielding high-accessibility levels (a combination of feeling-of-knowing and tip-of-the-tongue ratings) in comparison with those yielding low-accessibility levels in a rare word definition task. Experiment 2 yielded the same pattern even though lexical decisions preceded accessibility estimates by a full week. Experiment 3 dismissed the possibility that the Experiment 2 results may have been due to a long-term influence from the lexical decision task to the rare word judgment task. These results support a model in which Ss (a) retrieve topic familiarity information in making accessibility estimates in the rare word definition task and (b) use this information to modulate lexical decision performance.     

Ethnic pride and self-control related to protective and risk factors: test of the theoretical model for the strong African American families program.

OBJECTIVE: To test a theoretical model of how ethnic pride and self-control are related to risk and protective factors. DESIGN: A community sample of 670 African American youth (mean age = 11.2 years) were interviewed in households. MAIN OUTCOME MEASURES: Measures of cigarette smoking, alcohol use, and sexual behavior (lifetime to past month). RESULTS: Structural modeling analyses indicated parenting was related to self-control and self-esteem, and racial socialization was related to ethnic pride. Self-control and self-esteem variables were related to levels of deviance-prone attitudes and to perceptions of engagers in, or abstainers from, substance use and sexual behavior. The proximal factors (behavioral willingness, resistance efficacy, and peer behavior) had substantial relations to the criterion variables. Participant gender and parental education also had several paths in the model. Results were generally similar for the 2 outcome behaviors. CONCLUSIONS: In this population, self-esteem and self-control are related to parenting approaches and have pathways to attitudes and social perceptions that are significant factors for predisposing to, or protecting against, early involvement in substance use and sexual behavior.
