Concurrent and longitudinal relations among parental emotional expressivity, children's sympathy and children's prosocial behavior were assessed with correlations and structural equation modeling when the children were 55–97 months old (N = 214; M age = 73 months, SD = 9.59) and eight years later (N = 130; ages 150–195 months old, M = 171 months, SD = 10.01). Parent emotional expressivity (positive and negative) and children's sympathy were stable across time and early parent‐reported sympathy predicted adolescents' sympathy and prosocial behavior. Parents' positive expressivity was positively related to sympathy and prosocial behavior, but in adolescence, this was likely primarily because of consistency over time. Early observed parental negative expressivity was negatively related to adolescents' prosocial behavior. Reported negative expressivity in childhood was negatively related to boys' sympathy in childhood and positively related to girls' sympathy behavior in adolescence. The later relation remained significant when controlling for the stability of parental expressivity and sympathy, suggesting an emerging positive relation between the variables for girls.  相似文献

The present work examined the detection of racial bias through thin slices of nonverbal behavior. Thirty Black and 30 White American judges rated the nonverbal behavior displayed by White individuals from 20-seconds of silent videotape of an interaction with either a Black or a White confederate. Correlations between judges nonverbal ratings and targets scores on a response latency measure of racial bias (i.e., Implicit Association Test, IAT) as well as on a self-report racial bias measure (i.e., Affective Prejudice Scale) were obtained. Results revealed that relative to White judges, Black judges nonverbal behavioral ratings were better predictors of both White individuals IAT and explicit racial bias scores, but only if those targets were engaged in an interracial dyad. The results are consistent with recent research finding that subtle forms of racial bias leak through nonverbal behavior, as well as with work noting the predictive accuracy of judgments made from thin-slices of nonverbal behavior.Jennifer A.

This longitudinal study evaluated the learning and retention of task-specific training during the subjects' classroom performance of a one-person pivot transfer. Twelve subjects were videotaped completing the transfer (pretest). The subjects then participated in a two-hour training session. One week later (posttest 1), and one year later (posttest 2) the subjects were videotaped again. A checklist was used to analyze the videotapes. A one-way ANOVA with repeated measures revealed that there was a statistically significant difference between the tests (F = 243.73, p-value < 0.0001). A post hoc analysis (Bonferroni procedure) indicated that the posttest 1 scores (mean = 13, SD = 0.40) were significantly higher than the pretest scores (mean = 2.96, SD = 0.39) indicating an improved score on the checklist. There was no significant difference between the scores of posttest 1 and posttest 2 (mean = 12.79, SD = 0.60) indicating that subjects continued to perform the task with proper body mechanics one year post training.  相似文献

We describe the natural history of 13 musculoskeletal conditions requiring hospitalization and identify demographic, behavioral, psychosocial, occupational, and clinical characteristics most strongly associated with disability discharge from the Army. Subjects included 15,268 active-duty personnel hospitalized for a common musculoskeletal condition between the years 1989-1996 who were retrospectively followed through 1997. Back conditions had the greatest 5-year cumulative risk of disability (21%, 19%, and 17% for intervertebral disc displacement, intervertebral disc degeneration, and nonspecific low back pain, respectively). Cox proportional hazards models identified the following risk factors for disability among males: lower pay grade, musculoskeletal diagnosis, shorter length of service, older age, occupational category, lower job satisfaction, recurrent musculoskeletal hospitalizations, more cigarette smoking, greater work stress, and heavier physical demands. Among females, fewer covariates reached statistical significance, although lower education level was significant in more than one model. Modifiable risk factors related to work (job satisfaction, work stress, physical demands, occupation) and health behaviors (smoking) suggest possible targets for intervention.  相似文献

High-risk drinking is among the top three prevention priorities of the Department of Defense. Research suggests that enlisted male soldiers are particularly at risk for unhealthy drinking behaviors. 292,023 enlisted male soldiers who responded to a Health Risk Appraisal (HRA) survey between 1990 and 1998 were dichotomized into high and low-risk drinking groups. Logistic regression analysis showed that high-risk drinkers wore seatbelts less frequently, were more likely to drive > 15 mph over the speed limit, and to smoke more than 20 cigarettes/day. This high-risk group was predominately young (< 25), Caucasian, high school educated or less, and most likely employed as infantrymen or craftsworkers. The two highest risk occupational groups (infantrymen and craftsworkers) differ from each other, and from other Army occupations. Intervention programs should include safe driving habits and smoking cessation, as well as high-risk drinking, and should be tailored to the specific needs of the group at highest risk.  相似文献

Experiments are a well-suited method for empirically studying cause-and-effect relationships. This article provides a guideline for designing experiments. We develop an integrative framework that illustrates the key decisions in designing experimental studies. With this framework, we discuss important problem areas in the design of experiments (e.g., determining the experimental setting, choosing participants). Finally, for the different decisions and identified problem areas, we derive concrete recommendations for designing experimental studies in marketing research.  相似文献

Widowhood is a stressful event for women, often coinciding with health, financial, and relationship losses. Researchers have considered many aspects of women's adjustment to widowhood, typically including social support in analyses. This study analyzed relationships between social support and adjustment from 19 previous widowhood studies. Contrary to intuition and most researchers' assumptions, the majority of relationships did not show that social support positively impacted adjustment. Analyses examined whether type of support or study methods affected the likelihood of finding a significant relationship between support and adjustment. Chi-square statistics indicated that neither of these factors influenced the effect of social support on women's adjustment to widowhood.  相似文献

Young women's experiences and perceptions of cunnilingus during adolescence   总被引:1,自引:1,他引:0  
Recent studies indicate that cunnilingus may be as prevalent as fellatio among American adolescents. Despite this approximate equivalence in rates, there is an imbalance in the amount and type of attention paid to fellatio and cunnilingus. Furthermore, there has been little empirical examination of young women's experiences and perceptions of cunnilingus during adolescence. Two studies in response to this gap in knowledge were conducted. In Study 1, regression analyses indicated that a young woman's sexual assertiveness was linked to having more lifetime cunnilingus partners, as well as more cunnilingus experiences in the past three months. Study 2 explored young women's perceptions of cunnilingus and their speculations about their male partners' perceptions thereof. Linear mixed modeling revealed that participants had highly favorable impressions of cunnilingus, which they believed their male partners shared. These findings are considered in terms of positive adolescent sexual development and cultural norms regarding female sexuality.  相似文献
