All 51 jurisdictions in the United States require physicians to report suspected child abuse. In most jurisdictions, reporting requirements override both confidentiality and privilege associated with the physician-patient relationship. The authors review the literature relevant to the conflict between privacy and reporting abuse and report the results of a national survey of therapists at sex offender treatment units. They discuss ethical problems experienced under these statutes by therapists who attempt to provide treatment for sex offenders, and by therapists who are required to report past instances of child abuse even when there is no evidence of ongoing abuse. 相似文献

Two hundred and sixty three young adult college students responded to openended questions assessing their specific intentions, motives, and plans for having children. The most commonly stated motives for childbearing reflected a strong interest in establishing an identity and social network. Financial, marital, and emotional stability were identified as important factors influencing the timing of parenthood. Several significant sex differences were found for both motives and the timing of parenthood. These findings are discussed in terms of changing social norms regarding parenthood and changing sex role expectations.Portions of this research were presented at the Eastern Regional Psychological Association Convention in New York, April 1986. This research was funded by a grant from Trenton State College, Committee for Faculty and Institutional Research and Sabbatical Leave. 相似文献

Data on 94 women gathered during four field trips to a village located in the Malnad area of Karnataka form the basis of this examination of changes in Havik Brahmin marriage patterns over a 20-year period. Four case studies of marriages and two case studies of single women illustrate social change, particularly the influence of increased education, marriage age, and marriage choice. These case studies illustrate that, with an increase in marriage age and an increase in educational level, women have increased independence as daughters, brides, wives, and mothers. Concurrent with this is a decreased emphasis on ritual. Women have become assertive as they have perceived options. The socialization of women into learned helplessness and absolute dependence on men is in the past. Where women were perceived and perceived themselves as forever childlike, they now have grown to maturity. Men have to acknowledge women's educational achievements, especially when sisters achieve more than their brothers. With the recognition of feminine achievement has come increased independence for women. Mothers who have been bitter about their own limitations have encouraged daughters to achieve. With a change from an ascribed status of men as superior to achieved status based on merit has come increased opportunities for women. 相似文献

The file drawer problem refers to a publication bias for positive results, leading to studies which support the null hypothesis being relegated to the file drawer. The assumption is that researchers are unable to publish studies with nonsignificant findings. A survey of investigators studying the menstrual cycle showed this assumption to be unwarranted. Much of the research did not lend itself to a hypothesis-testing model. A more important contribution to the likelihood of publication was research productivity, and researchers whose first study was published were more likely to have continued their work. 相似文献

Perceived control (PC) is defined as thebelief that one can determine one’s own internal states and behavior, influence one’s environment, and/or bring about desired outcomes.
Two important dimensions of PC are delineated: (1) whether the object of control is located in the past or the future and
(2) whether the object of control is over outcome, behavior, or process. A variety of constructs and measures of PC (e.g.,
efficacy, attribution, and locus of control) are discussed in relation to these dimensions and selected studies are reviewed.
The issues, controversies, and limits of the research on perceived control and health are addressed in terms of the antecedents
and consequences of perceived control. Investigations should clearly conceptualize the object of perceived control, use measures
that match the conceptualization, and when attempting to manipulate control, directly measure perceived control. The relation
between PC and health outcomes is complex, and different aspects of PC may interact to affect health outcomes. 相似文献

Studies of speech perception first revealed a surprising discontinuity in the way in which stimulus values on a physical continuum are perceived. Data which demonstrate the effect in nonspeech modes have challenged the contention that categorical perception is a hallmark of the speech mode, but the psychophysical models that have been proposed have not resolved the issues raised by empirical findings. This study provides data from judgments of four sensory continua, two visual and two tactual-kinesthetic, which show that the adaptation level for a set of stimuli serves as a category boundary whether stimuli on the continuum differ by linear or logarithmic increments. For all sensory continua studied, discrimination of stimuli belonging to different perceptual categories was more accurate than discrimination of stimuli belonging to the same perceptual category. Moreover, shifts in the adaptation level produced shifts in the location of the category boundary. The concept of Adaptation-level Based Categorization (ABC) provides a unified account of judgmental processes in categorical perception without recourse to post hoc constructs such as implicit anchors or external referents. 相似文献

Previous research has failed to demonstrate unambiguously the relative stability across time and consistency across tasks of individual differences in categorization, or categorization breadth The present study of categorizing behavior in college students assesses breadth at each of four points in time over a six-week period Results are consistent with an interpretation of breadth as a highly stable individual difference variable, but one that is constrained by the nature of the stimulus sets employed High stability coefficients were observed for each of two redundant tasks In contrast, cross-task consistency indices were generally low Personality correlates of breadth were similarly weak and inconsistent Several variables are suggested that may attenuate the generality of categorization breadth The existence of multiple styles of categorization is discussed 相似文献

Subjects seem to react to a word faster than they react to a letter within a word. One interpretation is that words are processed holistically; another is that all visual stimuli are processed in terms of components, but that more stimulus information is available for use when the targets are words than when they are letters within words. The results of three experiments indicate that the word or pattern-level advantage occurs even when the stimulus information in the two situations is equated, but if the perceptual arrays cannot be unitized (e.g., consonant sequences), a pattern-level advantage does not occur. In addition, the experiments provide substantial evidence to indicate that if letter arrays cannot be unitized, then they are processed on a componentby-component basis, rather than holistically. Finally, the appropriate definition ofholistic processing is considered. 相似文献
