3.5~5.5岁学前儿童年龄认知发展的研究   总被引:2,自引:0,他引:2  
该实验采用三个问题作业(“年龄比较”、“出生年龄”、“年龄变化”)及一个“图示作业”,调查了60名3.5~5.5岁儿童年龄认知的发生、发展情况,结果表明:3.5岁儿童处于年龄认知萌芽状态,4.5岁儿童年龄认知开始发生,5.5岁儿童的年龄认知已发展到较高水平。儿童年龄认知变化可用变化分割模型(简称CS模型)来解释。  相似文献

One of the most debated questions in psychology and cognitive science is the nature and the functioning of the mental processes involved in deductive reasoning. However, all existing theories refer to a specific deductive domain, like syllogistic, propositional or relational reasoning.
Our goal is to unify the main types of deductive reasoning into a single set of basic procedures. In particular, we bring together the microtheories developed from a mental models perspective in a single theory, for which we provide a formal foundation. We validate the theory through a computational model (UNICORE) which allows fine-grained predictions of subjects' performance in different reasoning domains.
The performance of the model is tested against the performance of experimental subjects—as reported in the relevant literature—in the three areas of syllogistic, relational and propositional reasoning. The computational model proves to be a satisfactory artificial subject, reproducing both correct and erroneous performance of the human subjects. Moreover, we introduce a developmental trend in the program, in order to simulate the performance of subjects of different ages, ranging from children (3–6) to adolescents (8–12) to adults (>21). The simulation model performs similarly to the subjects of different ages.
Our conclusion is that the validity of the mental model approach is confirmed for the deductive reasoning domain, and that it is possible to devise a unique mechanism able to deal with the specific subareas. The proposed computational model (UNICORE) represents such a unifying structure.  相似文献

The author researched sociocultural factors related to psychotherapy with victims of organized violence from different perspectives: a refugee counseling center in a metropolis (Frankfurt, 1991–95) and refugee camps in neighboring countries (Uganda, 1994–96). At first the psychopathology of victims of organized violence is described. Then a review of treatment approaches follows and a conceptual model for integrative psychotherapy is developed. On the basis of qualitative analysis of client–therapist interactions, case discussions, supervision, evaluation of treatment, and literature review, an eclectic model for ethnocultural counseling and psychotherapy was developed. This eclectic model can be divided into (1) therapeutic relationship and transference, (2) modeling techniques, (3) extrapsychic techniques, (4) somatic techniques,(5) working through traumatic/grief/repressive experiences, and (6) reeducative and supportive techniques.  相似文献

The study investigated whether involving parents in their child's cognitive-behavioral intervention would effectively reduce parent distress during their child's medical procedure. Parents participating with their 3- to 7-year-old children prior to a voiding cystourethrogram were randomly assigned to an intervention (N = 20) or a standard care (N = 20) condition. The intervention included provision of information, coping skills training, and parent coaching. Parents participating in the intervention had a significant reduction in anxiety following the intervention relative to parents in standard care. Trained parents displayed fewer distress-promoting and more coping-promoting behaviors during the procedure, even though parents in both conditions reported similar levels of anxiety during the procedure. Involving parents in children's interventions is crucial to reduce parent distress and prepare parents to assist their child during the medical procedure.  相似文献

We report one of the first multi-site investigations into referral source variation in functional impairment for children with serious emotional disturbance served in systems of care settings. Baseline data collected as part of the national evaluation for the Comprehensive Community Mental Health Services for Children and Their Families Program was used to assess the comparability of functional status for children referred from traditional mental health versus non-mental health agencies. Results indicate that children referred from child welfare and family groups have significantly lower levels of overall dysfunction than those referred from mental health, while children referred from school and juvenile justice agencies have comparable levels. Clinical and research implications are discussed.  相似文献

This paper reviews medical psychology in Iran and describes the two major professional associations representing the profession. The unique role of religion in Iran is stressed, and limitations of the current health care system are described. The paper also addresses human resource issues and the educational requirements for the practice of psychology in Iran.  相似文献

This study aims at a test and further refinement of the Demand–Control–Support (DCS) model among construction workers (N = 210). On the basis of theory and empirical evidence, we hypothesized that mental or physical job demands, low job control, and lack of social support at work have direct and synergistic effects on burnout. The model was expanded by hypothesizing that burnout mediates the relationships between these potentially demanding working conditions on the one hand, and health complaints on the other. Results of a series of structural equation analyses partly supported these hypotheses. The proposed model fitted adequately to the data, although some variables in the DCS model did not make a unique contribution to explaining variance in burnout and (indirectly) health complaints. Interestingly, lack of social support was the most important determinant of burnout and health complaints among construction workers. In addition, a significant three-way interaction effect partly confirmed the synergism hypothesis: Physical demands were only related to burnout if participants had poor job control and reported high social support. The implications of these findings for research and practice are discussed.  相似文献

This paper presents empirical research which demonstrates how snacks brands can satisfy certain personal values for female 11–12 year‐old British and Spanish consumers. The qualitative research design uses a means‐end approach, based on a laddering technique, to uncover the links between brand choice and personal values. After reviewing the means‐end model and other relevant theory, the research methodology and design are presented in detail. The findings reveal significant scope for positioning snacks brands using the values of well being and fun and enjoyment (UK and Spain), while the value of friendship and belonging emerges as an extra dimension for the British respondents.

The biblical sentence "God is Spirit" (John 4:24) occasioned the development of the Christian doctrine about God as Spirit. But since patristic times "spirit" was interpreted in the sense of Nus, which rather means "intellect." The biblical concept of spirit (pneuma), however, has its root meaning in referring to "air in movement," as in breath or storm. The similar concept of pneuma in Stoic philosophy has become the "immediate precursor" (Max Jammer) of the field concept in modern physics, so that the conclusion is suggested that God is spirit as something like a field of force rather than as intellect. This essay argues for such a conception by relating the divine eternity and immensity to the concepts of space and time, the basic requirements of any physical field. God's eternity and immensity are interpreted in terms of undivided infinite space (and time) which is presupposed in all concepts of parts of space or time (or space-time), therefore in all mathematical and physical measurement.  相似文献
