年龄与路径知识习得的关系是空间与认知老化两大领域研究的重要议题。老年人在面对不同的路径学习环境时呈现出不同的认知老化表现。以往与年龄相关的路径知识习得能力变化的研究, 主要支持了认知老化衰退理论。然而近来发现随着年龄增长, 老年人保留了一种空间认知补偿能力。由此, 在对前人文献进行回顾和反思的基础上, 整合路径知识习得的认知老化表现及机制以探究缓解空间认知老化可能的内部因素和外部有效措施。  相似文献

Multidimensional computerized adaptive testing (MCAT) has received increasing attention over the past few years in educational measurement. Like all other formats of CAT, item replenishment is an essential part of MCAT for its item bank maintenance and management, which governs retiring overexposed or obsolete items over time and replacing them with new ones. Moreover, calibration precision of the new items will directly affect the estimation accuracy of examinees’ ability vectors. In unidimensional CAT (UCAT) and cognitive diagnostic CAT, online calibration techniques have been developed to effectively calibrate new items. However, there has been very little discussion of online calibration in MCAT in the literature. Thus, this paper proposes new online calibration methods for MCAT based upon some popular methods used in UCAT. Three representative methods, Method A, the ‘one EM cycle’ method and the ‘multiple EM cycles’ method, are generalized to MCAT. Three simulation studies were conducted to compare the three new methods by manipulating three factors (test length, item bank design, and level of correlation between coordinate dimensions). The results showed that all the new methods were able to recover the item parameters accurately, and the adaptive online calibration designs showed some improvements compared to the random design under most conditions.  相似文献

The study examined how child and parent characteristics, and contextual sources of stress, such as marital conflict predict initial status and trajectories of parent involvement, support, and harsh control, over a 4‐year period in families in Taiwan (= 4,754). Based on Belsky's (1984) ecological model of parenting, three domains predicting parenting were tested, child characteristics (age cohort and gender), father and mother characteristics (education and depressive symptoms), and contextual sources of stress (marital conflict). The study followed two cohorts of children; the younger cohort was followed from first to fourth grade and the older cohort from fourth to seventh grade. Initially, fourth graders reported more parental involvement, support, and harsh control than first graders. However, involvement, support, and harsh control decreased across the 4 years for the older cohort as they transitioned to early adolescence. In the first year, girls reported more parental involvement and support and less harsh control than boys. Across the 4 years, involvement and support increased, and harsh control decreased for boys; whereas involvement stayed the same, support slightly decreased, and harsh control slightly increased for girls. Children whose parents were more educated reported more parent involvement, support, and harsh control in the first year. Children whose fathers were chronically depressed and whose parents were experiencing marital conflict reported decreasing parent involvement and support over the years.  相似文献

Clergy experience a large number of stressors in their work, including role overload and emotional labor. Although studies have found high rates of depression in clergy, the degree of work-related burnout in clergy compared to other occupations is unknown. The widely used Maslach Burnout Inventory (MBI) measures three aspects of burnout: emotional exhaustion, depersonalization, and personal accomplishment. We sought studies using comparable versions of the MBI for clergy; for social workers, counselors, and teachers because of those occupations’ emotional intensity and labor; and for police and emergency personnel because of the unpredictability and stress-related physiological arousal in those occupations. We found a total of 84 studies and compared the ranges of burnout scores between the studies of clergy, each additional occupation, and MBI published mean norms. Compared to U.S. norms, clergy exhibited moderate rates of burnout. Across the three kinds of burnout, clergy scores were relatively better than those of police and emergency personnel, similar to those of social workers and teachers, and worse than those of counselors. Clergy may benefit from burnout prevention strategies used by counselors. The moderate levels of burnout found for clergy, despite the numerous stressors associated with their occupation, suggest that clergy generally cope well and may be models to study. Overall, there is room for improvement in burnout for all professions, especially police and emergency personnel. It is important to remember the variation within any profession, including clergy, and prevent and address burnout for those in need.  相似文献

The current longitudinal study examined whether the personality vulnerabilities of self-criticism and dependency prospectively predicted stress generation in Chinese adolescents. Participants included 1,116 adolescents (588 girls and 528 boys), aged 15 to 18 years from rural, urban and ultra-urban mainland China. Participants completed self-report measures of personality, depressive and anxious symptoms and participated in a clinical interview assessing lifetime history of depression. The occurrence of negative life events was measured using a contextual-threat interview every 6-months for a total period of 18-months. Logistic regression analyses showed that after controlling for past depressive episodes and current depressive and anxious symptoms, self-criticism was prospectively associated with the occurrence of interpersonal stress generation, but not noninterpersonal stress generation. Dependency also predicted interpersonal stress generation, although only in girls and not boys. In line with previous Western findings, girls reported more interpersonal stress generation. Analyses across 3 levels of urbanization revealed several significant differences including higher reported interpersonal stress generation in urban girls than urban boys and overall higher levels of negative life events in ultra-urban youth. In sum, findings from the current study suggest that the stress generation process may be generalizable to Chinese youth.  相似文献

Conduct disorder (CD) symptoms and callous-unemotional (CU) traits have been shown to be uniquely associated with risky sexual behavior (RSB) in adolescence and early adulthood, yet their interactive role in predicting RSB remains largely unknown. This study aimed to investigate the predictive value of CD symptoms and CU traits, as well as their interaction, on several RSB outcomes in adolescence and early adulthood. A total of 683 participants (41.7 % female, 47.4 % African American) were followed annually and self-reported age of first sexual intercourse, frequency of condom use, pregnancy, contraction of sexually transmitted infections, and engagement in sexual solicitation from grade 7 to 2-years post-high school. CD symptoms predicted age of first sexual intercourse, condom use, and sexual solicitation. CU traits predicted age of first sexual intercourse and pregnancy. Their interaction predicted a composite score of these RSBs such that CD symptoms positively predicted the composite score among those with high levels of CU traits but not among those with low levels of CU traits. The current findings provide information regarding the importance of both CD symptoms and CU traits in understanding adolescent and early adulthood RSB, as well as the benefits of examining multiple RSB outcomes during this developmental period. These findings have implications for the development and implementation of preventive efforts to target these risky behaviors among adolescents and young adults.  相似文献

本研究通过使用美国国家儿童健康与人类发育研究所的纵向研究数据建立分层线性模型,探究在儿童的早期发展中,母亲抑郁症状对儿童的社会性退缩的影响,以及母亲的教养行为在这一关系中的中介作用,结果发现:(1)在儿童24~54个月期间,随着母亲抑郁症状的升高,儿童的社会性退缩也随之升高;(2)母亲抑郁症对儿童社会性退缩的影响存在着性别差异,与女孩相比,男孩的社会性退缩更容易受到母亲抑郁症状的影响;(3)在男孩中,消极的教养行为在母亲抑郁症状与男孩的社会性退缩之间起到了中介作用,而在女孩中,这一中介作用并不显著。  相似文献

This study examined the effect of self-esteem on subjective well-being, with focus on confirmation of mediator roles of interpersonal forgiveness and self-forgiveness among a sample of 475 college students. The participants completed a questionnaire packet that includes Rosenberg Self-Esteem Scale, Heartland Forgiveness Scale, and Subjective Well-Being Scale. Results revealed that self-esteem, interpersonal forgiveness, and self-forgiveness were all significantly correlated with subjective well-being. Bootstrap results indicated that both interpersonal forgiveness and self-forgiveness partially mediated self-esteem to subjective well-being. Structural equation modeling analysis also revealed significant paths from self-esteem to subjective well-being through both interpersonal forgiveness and self-forgiveness.  相似文献
