Previous work on children's intuitive knowledge about the natural world has documented their difficulty in acquiring an overarching concept of biological life that includes plants as well as humans and non‐human animals. It has also suggested that the acquisition of fundamental biological concepts like alive and die may be influenced by the language used to describe them, as evidenced by differences between English‐ and Indonesian‐speaking children's performance in tasks involving these concepts. Here, we examine one particularly important source of linguistic information available to children during this acquisition process: everyday conversations with their parents. We take a cross‐linguistic approach in analysing the evidence available to English‐ and Indonesian‐speaking children as they acquire meanings for words corresponding to the concepts alive and die . Our analysis illustrates that young children acquiring English and Indonesian are faced with distinct problems, but that parental input in both languages does little to support the acquisition of broad, inclusive biological concepts.  相似文献

The relation of the reading interests of Chinese adolescents to their personality (introversion), values (intellectualism and academic achievement), and the reading interests of their family members and peers was studied. A total of 2,114 secondary school students participated in the study. The hypothesized relationship was found to be positive. Specifically, the more introverted students were attracted to more literary materials, whereas the less introverted were fond of more action type of materials. Students high on the value of intellectualism were found to read in general more than those low on the value in almost any kind of materials. Compared to the low ones, students high on the value of academic achievement tended to read more but the differences were not extensive; their interest seemed to focus more on the literary and curriculum-related materials. With respect to family and peer influences, students with parents, siblings, classmates, and friends who read tended to read more and have wider reading interests.  相似文献

Psychological symptoms were found to be associated with a number of cognitive appraisal and demographic variables but predicted primarily by perceived lack of control among information seekers in the aftermath of the Three Mile Island accident. Cognitive appraisal variables were found to be interrelated in a way which suggests that appraisal of control and faith in experts mediate between perceived environmental threat and psychological symptoms among information seekers in the aftermath of technological disaster. Demographic variables such as education and evacuation status are viewed as mediators between environmental circumstances and cognitive appraisals.  相似文献

In its early stages, Parkinson's disease (P.D.) may be difficult to distinguish from major depression (M.D.) leading to inappropriate management. Both illnesses are characterized by psychomotor retardation. The neurovegetative symptoms used to diagnose M.D. are not specific and in P.D. may be due to the physical illness itself. Currently, differentiation of the two disorders relies on subjective clinical observation. Improved diagnostic accuracy based on more objective data is needed. To this end, this study used computerized acoustic analysis to contrast speech patterns in P.D. and M.D. The sample consisted of 30 P.D. patients without depression or dementia, 30 patients with uncomplicated M.D., and 31 normal controls, each 60 years of age or over. Of the acoustic variables studied, M.D. patients had significantly reduced rates of speech compared with P.D. patients. The data suggest that this temporal measure of speech may be useful in the differentiation of P.D. and M.D.  相似文献

Much of the methodology in stress research focuses on stress manifestation and organismic reactions to life’s crises. In contrast, the present study sought to identify the major sources of stress and the nature of those sources. The results revealed a consistent pattern in high and low stressors throughout the 3-year period of the study, and differences only of intensity between males and females, not type of stress. Except for individuals’ temporal variations in critical events, the highest stressors for the groups were external, primarily financial and time management. Internal sources, such as personal relationships and self-absorption, were typically the lowest concerns. Everyday problems arising from current life styles seem to be significant sources of stress.  相似文献

This paper introduces a framework by which the structural and communicative-interactive theories of family therapy can be logically and systematically applied with Asian/Pacific American families. It begins with an introduction to Schutz's FIRO theory and model. Application and relevance to work with Asian/Pacific American families is discussed and illustrated with a case application.Paper originally presented at the 1987 annual program meeting of the Council on Social Work Education, St. Louis, Missouri, March 8, 1987.  相似文献
