Positive and negative implications of two types of college-age narcissism on psychosocial functioning at midlife were studied in a longitudinal sample of women. Both types were scored with self-report measures when the women were, on the average, age 21. Throughout the first half of their adult life, high scorers on covert narcissism presented themselves as lacking in confidence and having low morale; high scorers on overt narcissism described themselves as wanting admiration, being independent, and being forceful. Positive outcomes associated with covert narcissism included the development of insight and of a differentiated sense of the self and, in the case of overt narcissism, entailed an involvement in high-status and creative work careers. At midlife, high scorers on covert narcissism experienced negative affect and feelings of being neglected, whereas high scorers on overt narcissism experienced family conflict and problems with impulse control. The personality characteristics associated with both types of narcissism remained stable from the early 20s to early 50s. 相似文献

This paper examines those children receiving mental health services in Puerto Rico, their demographic and psychosocial characteristics, and describes service providers and nature of facilities. The survey was done on a probability sample of children ages 4 through 16 across the island of Puerto Rico (N=777). Need for services was clinically defined as presence of a DSM-III diagnosis and functional impairment. The overall rate of service utilization for Puerto Rican children was 6% (26.2% of definite cases and 5.1% of probable cases). In most cases services were provided by psychologists and/or social workers, and they were mainly provided in schools and general medical facilities. In over 60% of the children assessed as cases, who did not receive services, the reason, given by the parent was that they considered the problem not serious. Factors associated with service utilization were measures of psychopathology, teacher's perceived need, and parental rates of criticism and hostility. These findings suggest that there is a need for more research on the motivating factors for service use (impairment and parental criticism). Teachers could benefit from receiving special training to help them readily recognize behavioral problems in children, communicate them to parents and set up services alternatives. 相似文献

对幼儿从电视中伴随学习单词的可能性及其影响因素进行了初步的探讨。40名小班幼儿和46名大班幼儿参加了实验,他们在接近自然的状态下观看有字幕的动画片。结果发现:幼儿在无任何指导的情况下观看有字幕的动画片,能伴随学习到汉字,这表明,电视对幼儿的词汇发展有着积极的影响;不同性别的儿童都能同等程度地从电视中伴随学习到单词;词义的伴随学习受幼儿原有的词汇水平和幼儿对目标词熟悉程度的影响;词音的伴随学习只发生在词汇水平较高的幼儿当中,并且随着幼儿对目标词熟悉程度的增加而增加;词音和词义的伴随学习存在频度效应。 相似文献

在汉语中,副词是一种比较独特的词类,它没有具体形象的物体可作为理解支柱,因而儿童对它的掌握较晚。在各类副词中,5、6岁儿童对范围副词的理解最佳,时间副词次之,程度副词最差。三者的差异均有非常显著性意义。即使在每一类副词中,由于儿童概念发展的不均衡性,掌握的顺序也有先后。 相似文献

Two studies using novel extensions of the conditioned head-turning method examined contributions of rhythmic and distributional properties of syllable strings to 8-month-old infants' speech segmentation. The two techniques introduced exploit fundamental, but complementary, properties of representational units. The first involved assessment of discriminative response maintenance when simple training stimuli were embedded in more complex speech contexts; the second involved measurement of infants' latencies in detecting extraneous signals superimposed on speech stimuli. A complex pattern of results is predicted if infants succeed in grouping syllables into higher-order units. Across the two studies, the predicted pattern of results emerged, indicating that rhythmic properties of speech play an important role in guiding infants toward potential linguistically relevant units and simultaneously demonstrating that the techniques proposed here provide valid, converging measures of infants' auditory representational units. 相似文献

小学儿童奖赏公平性的认知发展 总被引:2,自引:0,他引:2
采用信息加工研究途径并假设故事情境探索小学儿童对奖赏公平性的社会认知发展,并将儿童的发展与成人作对比。研究结果表明,7,9岁儿童容易将"均等"与"公平"混淆,还没形成一个稳定的分配模式,而12岁儿童已能运用"努力"、"成果"、"能力"等规则较为稳定地作出公平奖赏决定或评价,但还没达到对更高层次的社会准则的理解和掌握。儿童这一发展制约于他们的信息加工能力以及获得有关社会价值观的社会化过程。 相似文献

I offer some reminiscences occasioned by the death of Daniel Levinson, a modern pioneer in the study of the human life cycle. I clarify three controversial aspects of Levinson's theory—its universality, the role of critical life events, and the place of relationships—as well as briefly foreshadow findings from his forthcoming book on women. I show that relationships to people, enterprises, and social institutions are the stuff out of which the individual life structure—Levinson's central concept—is formed. Levinson's dream was of a society in which the developmental needs of adults were better understood and met so that they could more generatively fill their roles in the institutions upon which the young depend. He thought this essential to the evolution of a society that would be both more competent and more humane. In this dream, which was a product of his own difficult mid-life transition and a measure of the success he achieved in integrating its polarities, Levinson united a warm, scientific interest in others with an affectionate curiosity about nature. 相似文献

Attachment and temperament have each been thought to contribute to personality development; however, few empirical studies have examined the relations between the two. Thus, the purpose of this study was to investigate, in young adulthood, the relations among attachment, temperament, and two aspects of ego development, namely,overall ego development and ego development with respect tointimacy. One hundred and seven college students served as participants. Sixty one percent classified themselves as securely attached and 39% as insecurely attached. A factor analysis of the Emotionality-Activity-Sociability (EAS) Temperament Survey for Adults yielded a primary factor (labeled negative emotionality) that accounted for 41% of the variance. A regression analysis then revealed that both attachment status and temperament predicted overall ego development; however, only attachment status predicted ego development with respect to intimacy. Implications and directions for future research are discussed. 相似文献

A lack of studies which evaluate system change by tracking client outcomes is noted in the children's mental health area. This deficit may be a result of the inability of researchers to define outcomes and to draw conclusions about which measures reflect the efficacy of services and service delivery systems. This paper reviews five social validation surveys which examined children's mental health outcome measures. Based on the results of the five surveys, a model of critical behaviors and events is presented. This model will assist evaluators and researchers in understanding which critical events and behaviors should be measured to assess the impact of community-based mental health services for children. 相似文献
