WOMEN'S PRIME OF LIFE Is It the 50s?   总被引:1,自引:1,他引:0  
The hypothesis is advanced that the early 50s is women's prime of life, an androgynous time of good health combined with autonomy and relational security. In a sample of 700 college alumnae, aged 26–80, who were studied in 1983, women in their early 50s most often described their lives as "first-rate." In a longitudinal sample from the same institution in 1989, women in their early 50s also rated their quality of life as high. Conditions distinguishing the early 50s from earlier and/or later periods of the middle years included more "empty nests," better health, higher income, and more concern for parents. All but the last of these conditions were related to quality of life within each sample of "prime" women. In both samples, "prime" women showed confidence, involvement, security, and breadth of personality. Prime of life is offered as a useful concept in adult development.  相似文献

Family rituals express patterned, repeated, symbolic communication that is ordered, evocative, socially meaningful, and directly impacts upon family functioning. Seasonal celebrations, rites of passage, family traditions, and patterned family interactions serve to organize the family, mediate individual expectations, regulate family subsystems, and facilitate change. Clergy and psychotherapists can use an understanding of family rituals to better understand individuals in their family context, promote change through prescribing rituals, and help clients create new, healing rituals.  相似文献

Alternate 25-item short forms of the Sex-Role Egalitarianism Scale (SRES) were developed and examined for psychometric quality using data from a sample of 608 students. Internal consistency coefficients were .94 and .92 for the two forms, stability coefficients with a three-week test-retest in terval were .88 for each, and the coefficient of equivalence or alternate forms reliability was .87. As expected, females scored significantly more egalitarian than males on both short forms, and results of factor analyses pointed to unidimensional measurement of a single construct for males, females, and the total sample. Additional support for reliability and validity is overviewed. The abbreviated SRES forms appear to provide a psychometrically sound and time-efficient means for assessing egalitarian attitudes.  相似文献

This study was designed to examine the correlates of developmental psychological stress for 36 middle-aged professional men. Based on sex role convergence and role adjustment theories, two sets of predictor variables were hierarchically entered into a multiple regression equation with a third set of variables entered to control for individual stressors. Controlling for individual stressors, midlife stress outcome was found to be influenced only by role adjustment (R2=.3593). The sex role convergence cluster did not account for a significant increase in variance. Controlling for individual stressors, the best univariate predictors of stress outcome associated with the midlife transition were (a) the quality of the parent-adolescent relationship and (b) marital satisfaction.  相似文献

Interpersonal loss and self-mutilation   总被引:1,自引:0,他引:1  
Self-mutilation was hypothesized to increase in frequency during periods of interpersonal loss in a treatment program for seriously disturbed adolescents. The study examined changes in the frequency of acts of self-mutilation, aggression, and running away for 32 teenagers who experienced interpersonal loss when staff members left employment. Data were collected for a 4-year period. Statistical findings indicated that the frequency of self-mutilation increased significantly during the time period of anticipated loss, 2 weeks prior to staff terminations. There was no significant increase in the frequency of self-mutilation immediately following the staff terminations. Also, there was no significant change in the rates of aggression or running away either before or after the loss events. It was concluded that the time of anticipated loss was the period of highest risk for these adolescents in terms of self-mutilative behavior.  相似文献

From Dialog's PsychINFO database the number of studies with 6 species reported in the Psychological Abstracts was calculated for each year from 1967 to 1988. Also, the number of studies with an additional 11 species were calculated for each year from 1973 to 1988. A hand search in the Journal of the Experimental Analysis of Behavior and Learning and Motivation was also conducted to explore trends in studies on 12 species from 1970 to 1987. The numbers of studies on many species (e.g., baboons, bats, chimpanzees, dolphins, gerbils, guinea pigs, gorillas, hamsters, lemurs, mice, pigeons, rats, seals, and snakes) have remained stable. There has, however, been a steady decline in the numbers of studies on selected species (e.g., cats, dogs, and rabbits). Possible reasons for changing trends in studies on selected species include: increased costs, the cognitive emphasis in psychology, and arguably, animal rights activism.  相似文献

Two of W. V. Quine's most familiar doctrines are his endorsement of the distinction between underdetermination and indeterminacy, and his rejection of the distinction between analytic and synthetic truths. The author argues that these two doctrines are incompatible. In terms wholly acceptable to Quine, and based on the underdetermination/indeterminacy distinction, the author draws an exhaustive and exclusive distinction between two kinds of true sentences, and then argues that this corresponds to the traditional analytic/synthetic distinction. In an appendix the author expands on one aspect of the underdetermination/indeterminacy distinction, as construed here, and discusses, in passing, some of Quine's more general views on truth.  相似文献

Guidance and counseling in the schools lack focus and direction. Some attribute this confusion within guidance and counseling to a lack of a philosophical foundation. Little is known about the philosophical assumptions of counselors functioning in secondary schools. In this study, the counselors in the secondary schools of Iowa identified most frequently with the phenomenological orientation. The experience of the counselors was related to their philosophical orientation. Counselors with less experience subscribed to an existential orientation.  相似文献

An adult, with a puppet held at shoulder height on either side (within the infant's visual field), interacted with 3- to-6-month-olds, turning her head intermittently to talk to a puppet. Seventy- three percent of infants' first eye-turns were in the direction of the adult head-turn.  相似文献

Dienes and Berry (1997) argue that there really are two kinds of knowledge, implicit and explicit, that can be characterized through a subjective threshold. We argue that the subjective threshold does not separate two forms of knowledge, but instead two uses of knowledge, for two different purposes. With Neal and Hesketh (1997), we suggest that an understanding of learning will be better served by investigating the processing that occurs under various circumstances than by attempting to isolate learning that occurs with awareness from that which occurs without it.  相似文献
