Phenomena of language teaching and learning in the course of verbal interactions between one mother and her daughter were analyzed. The daughter was between 18 and 27 months old during the recordings, and her utterance length ranged from 1,5 to 4,0 morphemes. Twenty hours of interactions were analyzed and the emphasis was placed upon sequential aspects and mathemagenic features of the conversations. It was demonstrated that the mother performs much analytic, synthetic, abstracting, and word-class-defining work during these verbal interactions. These maternal instructional activities seem to lead not only to the child's learning of language rules but also to her employment of the abstracting, analytical, and synthetic methodology. It is concluded that the main explanatory focus has to be on the mother in the attempts to explain language transmission and acquisition. Basic similarities to other instructional/skill training situations are suggested. Neither extraordinary complex cognitive nor innate linguistic capacities need to be assumed to explain the phenomena in question. 相似文献

A group of 211 first-to fourth-grade children who had experienced one or more recent stressful life events were compared to a demographically matched sample of 211 children who had not experienced such events on measures of school adjustment problems and competencies. Stressful life events were found to be associated with the presence of more serious school adjustment problems and fewer competencies. Those associations were strongest for children who had experienced multiple recent stressful events. The importance of preventive interventions for this at-risk group was emphasized and future research steps in the area were considered. 相似文献

Preweanling (21 days old) and adult (60-80 days old) rats were exposed to ethanol odor either paired with the early stages of apomorphine-induced toxicosis, paired with the recovery from toxicosis, or unpaired with the induction of distress. Twenty four hours later, ethanol preferences were measured in a spatial olfactory test (ethanol vs lemon odor) or a drinking test (5.6% v/v ethanol vs 0.25% w/v citric acid solutions). During the olfactory test both young and adult rats expressed substantial ethanol odor aversions when previously exposed to this odor paired with toxicosis. However, changes in ethanol intake became apparent only in preweanling subjects. Preweanlings which received the ethanol odor paired with illness drank significantly less of the ethanol solution relative to controls, while subjects experiencing the odor paired with recovery from distress significantly increased their consumption of the ethanol solution. These prior aversive and appetitive olfactory experiences had no effect upon ethanol intake in adult rats. These results implicate both an ontogenetic and a sensorial factor in the regulation of ethanol intake. 相似文献

The suppression of corticosterone synthesis with metyrapone (25 mg/kg) reduced the hyperactivity and altered the exploratory activity of hippocampally lesioned animals (HPC) in the open field to the level of cortical and sham controls (Experiment 1). In a second experiment, corticosterone (600 micrograms/kg) pretreatment 2 h, but not 1 h, before metyrapone partially restored the hyperactivity of HPC animals that had been decreased by the corticosteroid-suppressant drug. Alterations in exploratory behavior induced by metyrapone were also prevented by corticosterone pretreatment. The results suggest that the suppression of corticosterone in hippocampally lesioned animals produces a normalization of behavior that can be prevented by pretreatment with corticosterone. 相似文献

Male rats isolated for 60 days in adulthood spent less time investigating odors of females and urine-marked less over these odors than did males kept in groups of three. Isolated males did not differ from grouped males in their responses to odors of unfamiliar males or their own odors. After social experience the isolated males showed an increase in urine-marking but no change in odor preferences. Individual housing therefore appears to alter olfactory communication in the same way that it does other social behaviors and these changes may be mediated by the same mechanisms. 相似文献

In the present investigation, we integrated self-theories (specifically, theories of cognitive consistency and self-esteem) with attribution theory. Our intent was to clarify the effects of different levels of self-esteem and performance satisfaction on causal internalization of academic performance. Subjects were 162 university students who attributed causality for their individual performances on a midterm examination. Attributions to four internal and four external causal sources were analyzed with a 2 × 2 (Self-Concept × Performance Satisfaction) MANOVA and with follow-up univariate F ratios. Most of the findings support the predictions based on self-esteem theory; i.e., satisfaction with performance, rather than consistency of performance with self-esteem, served as the primary influence on internalization of causality, with students internalizing satisfying outcomes more than dissatisfying outcomes. Cognitive-consistency theory and B. Weiner's (1979, Journal of Educational Psychology, 71, 3–25) attribution proposal regarding maintenance of a stable self-concept also received support, as attributions to the internal and stable causal sources of ability and general effort were a function of an interaction of self-esteem and performance satisfaction. Hence, neither self-theory adequately anticipated the effects of self-esteem and performance satisfaction on causal internalization. Rather, a consolidation of theories is needed to explain the results. 相似文献

This article reviews cognitive-behavioral assessment principles and procedures. The functions of such assessments are noted, and issues and advances in cognitive assessment are discussed. The need for integrated cognitive, behavioral, and affective assessments is then explored. Finally, conceptual methodological, and clinical issues in the integration of assessments and study of reciprocal determinants are presented.Preparation of this paper was supported in part by a General Research Board Faculty Research Award from the University of Maryland. The author would like to thank Steve Graham, Donald Meichenbaum, Barbara Keogh, and Bernice Wong for their feedback during the preparation of this paper. 相似文献

It is argued that stable, individual differences in helping behavior have not generally been observed in previous research because of the type of helping studied. This paper advocates the study of planned helping behavior as opposed to spontaneous helping behavior. The results of three studies are reported. In Study 1, an instrument designed to measure level of involvement in planned helping activities was developed. Scores on this instrument were found to be stable over a 7-month period. Further analysis revealed two major types of planned helping: (a) formal, organizational helping and (b) informal helping between friends and family. Study 2 examined a variety of intrapsychic and demographic correlates of formal and informal planned helping. Study 3 found support for the hypothesis that people in helping professions have higher levels of involvement in everyday planned helping than do people in nonhelping occupations. It is concluded that the study of planned helping, although posing methodological difficulties, is a necessary adjunct to experimental research. 相似文献
