Change in cognitive abilities was assessed over a 6-year period in a sample of monozygotic and same-sex dizygotic twin pairs (N = 507 individuals), aged 80 and older (mean age = 83.3 years: SD = 3.1). who remained nondemented over the course of the study. Latent growth models (LGMs) show that chronological age and time to death are consistent predictors of decline in measures of memory, reasoning, speed, and verbal abilities. Multivariate LGM analysis resulted in weak and often negative correlations among rates of change between individuals within twin pairs, indicating greater differential change within twin pairs than occurs on average across twin pairs. These findings highlight several challenges for estimating genetic sources of variance in the context of compromised health and mortality-related change.  相似文献

Data regarding individual differences in children's regulation, emotionality, quality of socioemotional functioning, and shyness were obtained from teachers and peers for 112 Indonesian 6th graders. Similar data (plus parents' reports) also were collected when these children were in 3rd grade. For boys, regulation and low negative emotionality generally predicted positive socioemotional functioning (e.g., social skills, adjustment, prosocial tendencies and peer liking, sympathy) within and across time and across reporters, even at the follow-up when initial levels of regulation or negative emotionality were controlled. For girls, relations were obtained primarily for concurrent teacher reports, probably because girls tended to be fairly well regulated and socially competent and variability in their scores was relatively low. Shyness for both sexes tended to be associated with concurrent measures of low regulation, high negative emotionality, and low quality of social competence.  相似文献

Asymmetrical gait patterns such as the gallop provide insight into the complexity of human locomotion. The nature of spontaneous (e.g., walk-run), quasi-spontaneous (e.g., gallop-walk), and intentional (e.g., walk-gallop) transitions was analyzed in 2 ways in the present study. In Analysis 1, the authors used step-wise regression to associate 10 physical characteristics with gait transitions. Transition predictability was moderate; thigh length best predicted 3 of 6 transitions. In Analysis 2, the dynamic characteristics of transitions (order parameters, phase shifts, multistability, and critical fluctuations) were described; those characteristics existed for all transition types. The results of the analyses suggest that intentional transitions are less biomechanically predictable than are spontaneous transitions and that transitions between gait pairs (e.g., walk-gallop and gallop-walk), regardless of velocity direction, have more in common than do transitions requiring specific intention.  相似文献

The personality of exemplary young adults was studied in an effort to paint a portrait of moral excellence that expanded upon the traditional emphasis on moral reasoning maturity. These young adults were nominated based on their extraordinary moral commitment towards various social organizations. The sample included 40 moral exemplars and 40 matched comparison individuals who responded to a battery of questionnaires and participated in a semistructured interview. It was found that moral exemplars, in contrast to comparison individuals, were more agreeable, more advanced in their faith and moral reasoning development, further along in forming an adult identity, and more willing to enter into close relationships. These findings are discussed in the context of describing moral excellence from a multifaceted, personality perspective.  相似文献

This study describes the effects of different weekly work intensity levels on adolescent functioning in a sample of 3,083 high school students in rural South Texas, where economically disadvantaged and Hispanic youth are heavily represented. Anonymous surveys were conducted in 10th- and 12th-grade students' classrooms in 1995. The following effects were associated with long hours of weekly employment during the school year: (1) decreased performance/engagement in school and satisfaction with amount of leisure time, and (2) increased health risk behaviors and psychological stress. The effects of school-year work on academic factors and health behaviors differed by grade, but not by race/ethnicity, parent education, or race/ethnicity and parent education considered together. It was concluded that parents and professionals should continue to monitor the number of weekly hours that students work during the school year.  相似文献

Shyness: relationship to social phobia and other psychiatric disorders   总被引:1,自引:0,他引:1  
The relationship between shyness, social phobia and other psychiatric disorders was examined. The prevalence of social phobia was significantly higher among shy persons (18%) compared with non-shy persons (3%). However, the majority of shy individuals (82%) were not socially phobic. A significant and positive correlation was found between the severity of shyness and the presence of social phobia, but the data suggest that social phobia is not merely severe shyness. Social phobia was also positively and moderately correlated with introversion and neuroticism. Thus, shy persons with social phobia were shyer, more introverted, and more neurotic than other shy people, but none of these factors was sufficient to distinguish shy persons with social phobia from those without social phobia. The proportion of the shy group with psychiatric diagnoses other than social phobia was significantly higher than among the non-shy group, indicating that various diagnostic categories are prominent among the shy. The results are discussed in terms of the overlap in shyness and social phobia and the relationship of shyness to other psychiatric diagnoses and personality dimensions.  相似文献

Latent growth models were applied to data from the Swedish Adoption/Twin Study of Aging to discover if the rate of change in cognitive performance increased from middle age to later adulthood. The sample included 590 participants aged 44 to 88 years at first measurement. Data were gathered at 2 follow-up occasions at intervals of 3 years. Cognitive ability was assessed through 11 tests that tapped crystallized, fluid, memory, and spatial abilities and perceptual speed. Results indicated stability for measures of crystallized ability, linear age changes for many cognitive abilities, and a significant acceleration in linear decline after age 65 for measures with a large speed component. Gender differences were found only in mean level, not in rate of decline.  相似文献

The Ego Impairment Index (EII; Perry & Viglione, 1991) is a composite measure of psychological impairment and thought disturbance developed from the empirical and theoretical literature on the Rorschach. In this article, we summarize reliability and validity data regarding the EII. Our major goal was to present the rationale and empirical basis for recent refinements in the EII. Among the subcomponents of the original EII was the Human Experience variable (HEV), which has recently been revised and replaced with the Human Representational variable (HRV; Viglione, Perry, Jansak, Meyer, & Exner, 2003). In this study, we replaced the HEV with the HRV to create the EII-2. This was accomplished by recalculating the factor coefficients with a sample of 363 Rorschach protocols. We present additional validity data for the new EII-2. Research recommendations and interpretive guidelines are also presented.  相似文献

The purpose of this study, using an online methodology, was to investigate therapists' perceptions of the role of creativity in couples' and family therapy. Along with completing a quantitative measure assessing creativity in their work, participants responded to four open-ended questions which addressed the meaning of creativity, characteristics of a creative family therapist, some creative interventions they have used with couples and families, and barriers to their own creativity as a family therapist. A total of 142 marriage and family therapists in 36 states in the United States participated. The findings shed light on the unique importance of creativity in couples and family treatment.  相似文献
