The present study investigated spatial memory in domestic dogs (Canis familiaris) through the use of a radial arm maze. The study consisted of a total of three separate experiments. In the first two experiments, the ability of the dogs to successfully remember previously unentered arms was evaluated. The third experiment was similar to the first two, but also examined the nature of the serial position effect. Performance in all three experiments was better than expected solely by random choices. Dogs showed a much better memory for spatial locations presented earlier in a spatial list compared with those presented in the middle. Based on the present results, we suggest that the radial arm maze assesses canine spatial memory and that dogs show a primacy effect.

The self-concept is one of the main organizing constructs in the behavioral sciences because it influences how people interpret their environment, the choices they make, whether and how they initiate action, and the pursuit of specific goals. Because belonging to social groups and feeling interconnected is critical to human survival, the authors propose that people spontaneously change their working self-concept so that they are more similar to salient social categories. Specifically, 4 studies investigated whether activating a variety of social categories (i.e., jocks, hippies, the overweight, Blacks, and Asians) increased associations between the self and the target category. Whereas Studies 1 and 2 focused on associations between stereotypic traits and the self, Studies 3 and 4 examined self-perceptions and self-categorizations, respectively. The results provide consistent evidence that following social category priming, people synchronized the self to the activated category. Furthermore, the findings indicate that factors that influence category activation, such as social goals, and factors that induce a focus on the interconnectedness of the self, such as an interdependent vs. independent self-construal, can impact this process. The implications of changes to the working self-concept for intergroup relations are discussed.  相似文献

The diagnostic efficiency of the Personality Assessment Screener (PAS; Morey, 1997) total score was evaluated using selected scales from the Patient Health Questionnaire (Spitzer, Kroenke, & Williams, 1999), the fourth edition of the Personality Diagnostic Questionnaire (Hyler, 1994), and the Alcohol Use Disorders Identification Test (Saunders, Aasland, Babor, DeLaFuente, & Grant, 1993) as reference standards. Complete data were collected from 110 women seeking treatment at an urban family medicine training clinic. Total PAS scores were effective in identifying patients with mood disorders, cluster B personality disorders, and alcohol use disorders, but the optimum cut scores were higher than the cut score of 19 recommended by Morey (1997). The 10 PAS element scores showed good convergent and discriminant correlations with the reference measures. These findings support the utility of the PAS to screen for major forms of psychopathology in an urban primary care setting.  相似文献

Our research explores the correlates of spiritual experiences over a 2-year period in a sample of older adults (N = 164; mean age 81.9 years) living in a continuing care retirement community. Utilizing responses to the Daily Spiritual Experiences Scale, scores were analyzed for changes over time and for their hypothesized moderating effect in the relationship between chronic illness impact and markers of psychological well-being (as measured by the Geriatric Depression and Life Satisfaction scales). Repeated measures ANOVA indicated a significant decline (P < .01) in the reported spiritual experiences over a 2-year period of time, and t tests showed a significant difference by gender (P < .01) in years 1 and 2, with women reporting higher levels of spiritual experiences than men. Analyses found low spirituality scores associated with low life satisfaction in all years (baseline: r = ?.288, P < .01; year 1: r = ?.209, P < .05; year 2: r = ?.330, P < .001). Only weak associations were detected between low spirituality and the presence of depressive symptoms at baseline (r = .186, P < .05) and year 2 (r = .254, P < .01). Moderation effects of spirituality on the relationship between chronic illness impact and markers of psychological well-being were explored in all years, with a statistically significant effect found only for the presence of depressive symptoms in year 2. Higher impact of chronic illnesses is associated with more depressive symptoms under conditions of low spirituality. Future research may center upon longer-duration evaluation of reliance upon spiritual practices and their impact in care management models.  相似文献

The study examined relationships between leaders' emotion regulation and leaders' and subordinates' work-related outcomes. Fifty-one school directors and 281 teachers reported on their strategies of emotion regulation (reappraisal, suppression), job satisfaction, and affect at work. For subordinates, suppression was negatively related to job satisfaction and was positively related to negative affect and emotional exhaustion, and reappraisal was positively related to job satisfaction and negatively to negativ affect. In contrast, multilevel analyses found that directors' use of reappraisal was neg atively related to subordinates' job satisfaction, and directors' use of suppression wa positively related to subordinates' positive affect. Leaders' suppression interacted wit group cohesion to predict subordinates' negative affect. This is one of the first studies to find evidence for the possible tension between leaders' emotion regulation competencie and organizational-role interests.  相似文献

The health of clergy is important, and clergy may find health programming tailored to them more effective. Little is known about existing clergy health programs. We contacted Protestant denominational headquarters and searched academic databases and the Internet. We identified 56 clergy health programs and categorized them into prevention and personal enrichment; counseling; marriage and family enrichment; peer support; congregational health; congregational effectiveness; denominational enrichment; insurance/strategic pension plans; and referral-based programs. Only 13 of the programs engaged in outcomes evaluation. Using the Socioecological Framework, we found that many programs support individual-level and institutional-level changes, but few programs support congregational-level changes. Outcome evaluation strategies and a central repository for information on clergy health programs are needed.  相似文献

This study explores how parts of the clergy system interact in response to congregational and familial demands. Qualitative analysis of semi-structured interviews with twenty-four clergy and their spouses identified three clergy system models based on the spiritual meaning and relational dynamics between the clergy, their spouses, and the congregations: The living sacrifice model emphasizes service to the congregation at the expense of personal and familial needs; the faithful spouse and parent model focuses on family needs over the congregation and practices several disciplines to maintain such a focus; and the peacemaker model seeks as much as possible to satisfy their congregation and their family by intentionally juggling their demands. Results illustrate how relational processes and spiritual meaning contribute to how clergy systems respond to systemic demands and pressures.  相似文献

Effect of contraction intensity [100%, 75%, 50%, and 25% maximum voluntary contraction (MVC)] and movement velocity [0 degrees (isometric)], 50 degrees, 100 degrees, 200 degrees, and 400 degrees/sec. [isovelocities]) on root mean square amplitude (SEMG-RMS) and median frequency power spectrum (SEMG-MNF) of vastus lateralis (VL) surface electromyography was investigated with ten healthy female university students. Peak torque (PT), mean torque (MT), SEMG-MNF, and SEMG-RMS, analyzed using separate repeated-measures analyses of variance (p < or = .05), indicated: (1) an inverse relation between PT and MT and movement velocity, (2) greater SEMG-MNF values during all isovelocity conditions compared with isometric conditions, with highest values occurring at 50 degrees /sec. and at 100% and 75% MVC, and (3) at all contraction intensities SEMG-RMS values were higher during dynamic movements than isometric movements and highest at 200 degrees /sec. Isovelocity contractions were inferred to facilitate a greater recruitment of fast-twitch fibers (via increased SEMG-MNF), which was intensified at 50 degrees /sec., whereas greater overall muscle activation was found at 200 degrees /sec.  相似文献

Data from a sample of 83 elected community leaders and 391 direct-report staff (resulting in 333 useable leader-member dyads) were reanalyzed to test relations between self-other rating agreement of servant leadership and member-reported leader-member exchange (LMX). Polynomial regression analysis indicated that the self-other rating agreement model was not statistically significant. Instead, all of the variance in member-reported LMX was accounted for by the others' ratings component alone.  相似文献
