The purpose of this study was to examine the predictive validity of a teacher nomination procedure for identifying at- risk children. Two hundred and twenty-five children were nominated by their teachers as well- adjusted (n= 75), socially withdrawn (n=76), or socially aggressive (n=74) during the fourth grade. Five years later, 198 of these children (88%) were located and their adjustment evaluated. Significant differences among the nominated children were found on a variety of measures, including academic grades, sociometric status, and social behavior. In addition, differences in school dropout and delinquent offenses were noted. Results are discussed in terms of the validity of teacher nomination procedures and their utility in identifying at- risk youth.  相似文献

Tail shock induces reflex sensitization inAplysiaand, in parallel, induces a number of modulatory effects in central neurons, such as increased excitability in tail sensory neurons (SNs) and facilitation of synaptic transmission from SNs to motor neurons. Both of these modulatory effects are mimicked by exogenous application of serotonin (5HT) or electrical stimulation of the tail nerve P9. In the present study we examined the activation thresholds for increased excitability and synaptic facilitation induced by either 5HT or P9 stimulation. We found that the concentration of 5HT sufficient to produce a significant increase in excitability produced no significant synaptic facilitation and, conversely, that the intensity of nerve stimulation sufficient to produce significant synaptic facilitation produced no excitability changes. This reversal of relative thresholds for these modulatory effects may reflect the differential access of exogenous 5HT and endogenous 5HT (released by tail nerve stimulation) to the SN cell body and synaptic terminals, respectively.  相似文献

Three experiments were conducted to examine whether people spontaneously remember the wording used to convey politeness. In all experiments, subjects heard statements varying in politeness that had been made by either a high-status (e.g., a professor) or equal-status (e.g., another student) speaker. Subjects’ incidental memory for these statements was then tested with either a recognition (Experiments 1 and 3) or a recall (Experiment 2) procedure. As expected, there was evidence of significant memory for wording that conveyed politeness, and subjects were more likely to remember forms that were incongruous with the speaker’s status. There was also some evidence that subjects encoded the politeness of a remark even when they were unable to recall the specific remark. The results demonstrate the role of the interpersonal dimension in the processing of language in context.  相似文献

Explanations of the tendency to put long, complex constituents at the ends of sentences (end-weight) usually take the listener's perspective, claiming it facilitates parsing. I argue for a speaker-oriented explanation of end-weight, based on how it facilitates utterance planning. Parsing is facilitated when as much tree structure as possible can be determined early in the string, but production is easiest when options for how to continue are kept open. That is, listeners should prefer early commitment and speakers should prefer late commitment. Corpus data show that different verbs exhibit different rates of word-order variation that are systematically related to differences in subcategorization possibilities in just the way predicted by a strategy of late commitment. Thus, a speaker-based account of lexical preferences in word ordering does a better job of explaining variation in weight effects than a listener-based account.  相似文献

This paper briefly describes the history of the professional interaction between psychoanalysts and analytical psychologists in the United States. There has been little public contact between the two groups since the personal feud between Freud and Jung has beer carried forth to the present generation of analysts. The relationship between Otto Rank and Freud and his circle demonstrated many of the same dynamics that were activated between Freud and Jung, who had broken off their relationship ten years earlier; this paper highlights the similarities between Jung's, then Rank's, exile from the psychoanalytic group, Jung's interest in spiritual matters, including his interest in the nature of religious experience, and his questionable dealing with the Nazis during the 1930s have been the stated reason for the taboo set against Jung's writings. Presently there seems to be a growing realization that there are large areas of mutual interest, and both the similarities and differences between the schools need further exploration.  相似文献

Abstract. Science and revelation have been presented as two books with the same “author,” their reconciliation being called “concordism.” Teilhard opposed concordism, insisting that supposed “revelations” be treated as scientific hypotheses to be verified or not in experience. Applying his criterion for truth (Does it bring “coherence and fecundity” to the phenomena?) to Christian revelation, he told of finding “an explosion of dazzling flashes.” So Teilhard spoke of the hypothesis as the supreme spiritual act wherein the dust of experience takes on form and is kindled at the fire of knowledge.  相似文献

This paper presents, discusses and evaluates empirical studies concerned with Christian prayer. These studies are classified within four main areas. The first area concerns what is known about the practice of prayer from empirical surveys and demonstrates that a much higher proportion of people pray privately than attend public places of worship. The second area concerns what is known about changing patterns of prayer during childhood and adolescence and argues that these changes need to be interpreted within the context of both developmental and social psychology. The third area concerns the subjective effects of prayer, beginning with Galton's early observations concerning the comparative longevity of the clergy (who are regarded as praying people) and including more recent studies of the psychological correlates of self-reported prayer, like personal well-being and purpose in life. It is concluded that, while such studies may demonstrate the beneficial nature of prayer, they cannot demonstrate the causal efficacy of prayer. The fourth area concerns the objective effects of prayer, beginning with Galton's early observations concerning the absence of comparative longevity among royalty (who are regarded as prayed for people) and including more recent studies of the growth correlates of prayer for pot plants. It is concluded that such studies currently provide contradictory evidence. It is recommended that further research in the field needs both to observe the strict criteria of objective empirical research and to be alert to theological nuances regarding the actual claims made for the efficacy of prayer within the community of believers.  相似文献
