This study investigated the process by which the representational activity and knowledge about drawing and letter and number writing emerge in children 21–46 months old. The results revealed that representational activities developed with age through several phases. Beginning at age 2, children produced different marks for different systems, but children under two produced common graphic marks. Representational systems were significantly correlated with developmental processes, but drawing developed faster than letters or numbers with respect to both their production and their classification. Three-year-old children were able to recognize each system correctly in a sample-matching task, but the recognition of each system was not correlated with representational activity. These findings indicate that only after children engaged in graphic production did they begin to make representational distinctions among systems by drawing on their domain-specific knowledge, although alternative explanations can be suggested. 相似文献

The purpose of the present study was to investigate causal relationships between dispositional and situational coping and health status in university freshmen. Two hundred and twenty-nine university freshmen completed questionnaires at Time 1 (immediately after university matriculation) and at Time 2 (approximately three months later) in a short-term, prospective study. Structural equation modeling was used to analyze causal relationships between four coping strategies (i.e., emotion expression, emotional support seeking, cognitive reinterpretation, and problem solving) and four health status variables (i.e., somatic symptoms, anxiety and insomnia, social dysfunction, and depression). Increases in dispositional coping predicted increases in situational coping at certain time points. In addition, increases in dispositional emotion-focused coping, such as emotion expression and emotional support seeking, predicted poor health status. This relationship was mediated by situational coping variables. Finally, increases in dispositional problem-focused coping, such as cognitive reinterpretation and problem solving, predicted better health status. This relationship was direct or indirectly mediated by situational coping variables. Our data suggest that the use of coping skills such as cognitive reinterpretation and problem solving may promote better health and adaptation in university freshmen. 相似文献

ABSTRACT— In this article, we posit a domain-general principle that may account for the improvement that is observed in several aspects of perceptual development over the first years of life. Development during this time frame is characterized by a process of perceptual narrowing, whereby the discrimination of perceptual information is broadly tuned at first and then declines to more selective levels with experience. This process appears to cut across both the visual and auditory modalities and may reflect the development of a common neural architecture. 相似文献

After briefly reviewing the unfavourable reception accorded empirical research by parts of the psychoanalytic community, as well as some of the benefits to clinical practice of analysts being involved in research activities, the author examines whether the findings of process and outcome research in psychotherapy and psychoanalysis can help identify the most appropriate forms of intervention for producing therapeutic change, given the specific condition of the patient and the relationship that the individual establishes with the analyst. He argues that research findings can influence clinical practice on various levels and in different areas, and goes on to examine a number of related issues: the specificity of therapeutic interventions versus the relevance of common curative factors; the dyadic conception of technique and ways of understanding the therapeutic action of the treatment alliance; and the strategic or heuristic conception in psychoanalytic therapy. Finally, the author presents clinical material with the aim of illustrating how the knowledge acquired through research can be applied to psychoanalytic treatment. 相似文献

采用单探测变化检测范式,考察了形状和颜色客体在工作记忆中的表征方式、特征检测类型及初始刺激呈现时间对工作记忆表征的影响。结果表明:(1)视觉客体工作记忆的表征包括两个水平,首先是对客体的特征进行加工存储,其次才是对特征的捆绑;(2)不同特征的加工时间不同,颜色的加工完成的较早,记忆效果好,而形状的加工完成的较晚,记忆效果也差,表现出颜色的子系统优势;(3)特征的捆绑不是必需的,只有在任务需要时才进行,并且捆绑的过程符合特征捆绑的双阶段理论。 相似文献

This study examined the mediating effect of career decision self-efficacy on the relationship between the Five-Factor Model of personality and the career commitment process (i.e., vocational commitment and the tendency to foreclose) in a sample of 785 Chinese graduate students. The multiple regression analyses showed that neuroticism and conscientiousness related significantly to progress in vocational commitment both directly and indirectly through career decision self-efficacy. High agreeableness related to less premature foreclosure. In addition, career decision self-efficacy associated with greater progress in vocational commitment but also a strong tendency to foreclose. The implications for career development theory and practice are discussed. 相似文献

The triangle, a concept in Bowen theory, is the emotional molecule in the family system that shapes the human over the course
of life. This longitudinal study explored the influence of the family of origin primary triangle on 51 couples’ family of
procreation functioning over 10 years. The quantitative analysis found associations between family of procreation functioning
and three variables: distance versus openness in the family of origin primary triangle, the degree of inside and outside positions
in the primary triangle, and the degree of family projection as expressed in worry. In addition, the three triangle relationships
correlated with each other, supporting the idea that each relationship influenced the other. Using qualitative methods, a
focused analysis elaborated on the quantitative findings. 相似文献
