The authors discuss the results of a study designed to assess nationally certified counselors' perceptions of the relevance of elements of the National Board for Certified Counselors examination to their work as counselors. Support for the validity and appropriateness of the examination in regard to perceived relevance and lack of differentiation on the basis of respondent characteristics were found.  相似文献

How is the concept of power integrated into the systemic organismic paradigm? Power concepts, especially Kantor and Lehr's six dimensions of distance regulation mechanisms, are related to several models of family therapy. Power is found to be a part of the Gestalt formation process of Perls, a process of dynamic selfregulation. Each family therapy model is regarded as part of an integrating process. A theory of conflict strategy and of integration strategy in therapy is developed. The article is intended to promote comparison and exploratory discussion around different models of family therapy.  相似文献

This paper reviews the research into a specific aspect of neardeath experiences (NDEs): the prophetic vision (PV). PVs are subjectively compelling flashforwards of planetary-wide cataclysms and eventual regeneration that sometimes occur during or in the immediate aftermath of an NDE. Previous research has shown that the most frequently mentioned year for the culmination of the geophysical calamities foreseen in PVs was 1988. I argue that PVs should be understood as manifestations of a collective prophetic impulse that historically tends to arise during periods of cultural crisis. PVs are thus expressions of the felt need for cultural renewal and therefore should not be taken literally as prognostic of drastic physical changes on Earth.  相似文献

Age differences in short-term retroactive interference, unconfounded with age differences in rehearsal in the retention interval of the Brown-Peterson Task, were not found in a cross-sectional study of adults 18-32 and 64-78 years of age. Degree of retroactive interference was manipulated conjointly with distractor interval length (0-15 s). Individual memory span was assessed and used as the list length in order to achieve stimulus equivalence of memory loads across individuals and age groups. An attention-demanding matching task that adjusted itself in difficulty to the individual's attentional capacity was used as the distractor activity. Covert rehearsal during the retention interval was inferred using several measures, including a comparison of distractor task performance in the presence and in the absence of a memory load, and rehearsers were excluded from the primary analyses. We conclude that there is no interference proneness with increasing age in the present study.  相似文献

Surviving members of the Berkeley Older Generation Study were interviewed and tested with the Wechsler Adult Intelligence Scale in 1969-1970 and again in 1983-1984, when subjects' ages ranged from 73 to 93. Health was assessed by self-reports at both measurement periods. Although many individuals showed some decline in intellectual functioning, substantial individual differences were apparent at all age levels. More than one half of the subjects showed no reliable change, and a minority showed a reliable increase in verbal scores. The role of self-reported health has increasing importance in the maintenance of intellectual functioning in advanced old age.  相似文献
