The efficacy of lithium carbonate as a treatment for manic-depressive illness has stimulated a reevaluation of the syndrome. In this paper, the authors review the obstacles to timely diagnosis of manic-depressive illness in the adolescent. Three cases are presented demonstrating the usefulness of a unitary concept in which manic-depressive illness is understood and appreciated as having a physiologic basis, manifesting its effects in the total body system. The heterofore diverse and confusing psychological and behavioral symptoms of manic depressive illness in adolescents become intelligible when regarded as secondary phenomena: the psychic experience of the process as filtered through the psychological constitution of the individual adolescent.Supported in part by a grant from Mr. and Mrs. A. Frank Rothschild, Sr.Received her postgraduate training in psychiatry at P&PI.  相似文献

This study generated adolescent women's perception of their identity in relation to family members spanning three generations and related these perceived relationships to their sex-role orientation. Subjects were 20 firstborn university women from intact families. The methodology used multiple sources of information, including open-ended interviewing procedures, rating scales, and standard research measures of sex-role identity. Significantly more constructs empirically differentiated family by generation than by sex. Congruence of young women with both the parent and grandparent generation, relative number of masculine stereotypes produced, and personality traits of males and females were significantly influenced by the presence of a brother in the sibling generation. There was no relationship between family constellation and sex-role orientation. Feminine women were significantly more congruent with other females in their family than androgynous women. There was a linear trend for androgynous women to be increasingly individuated across the generations.Received her Ph.D. from Yale University.

Similarity of ego identity status, assessed by Marcia's four-category classification system, was related to interpersonal attraction. Using male and female college students as subjects, this study found that (1) while all judges preferred targets who had or who are undergoing a crisis to those who have not had a crisis, (2) diffuse judges preferred targets with no commitments to those with commitments, and (3) judges with commitments preferred a foreclosure target more than judges without commitments. Differential evaluations of the targets' intelligence, knowledge of current events, adjustment, and morality were also found. Results are discussed both in terms of previous research positively relating personality similarity to attraction and Erikson's theory of the relationship between ego identity development and intimacy in interpersonal relations.  相似文献

Two studies were undertaken to examine parental influences on autonomy and identity development. In Study 1, 262 adolescents in seventh and eleventh grades were given Kurtines's autonomy measure, Simmons's identity measure, and Elder's questions regarding the adolescents' perceptions of their parents' autocratic, democratic, or permissive parenting styles. Study 2 was a replication with 168 subjects. Across both studies it was found that sex-role socialization is more influential for automony development than is either level of parental power or age. Both age and father's use of democracy were the most influential variables on identity development.Received Ph.D. from the University of Minnesota.
