In the kibbutz today, there are no ideological or economic barriers to prevent a couple from deciding to divorce. Both husband and wife are assured continued economic security and equal opportunities for co-parenting, thus reducing fears of disruption in the daily contact with the children. In spite of these favorable circumstances, marital breakups in the kibbutz are less frequent than in the larger cities in Israel. In recent years, however, at a time when a stronger and more intensive family life has gained legitimacy within the kibbutz structure, there is a marked tendency toward a rise in the rate of divorce. In this article we analyze the possible causes of the variations in the frequency of divorce within the kibbutz framework.The authors express appreciation to Esther Mivtzari, a psychologist on the staff of the Kibbutz Child and Family Clinic and a member of the religious kibbutz Ein-Tzurim, for assistance in gathering data on divorce in the religious kibbitzum.  相似文献

Homosexuals, bisexuals, and heterosexuals were compared on self-reported love preferences and ideals. In general, the three groups tended to agree on ideal characteristics of love objects, love relationships, and love related beliefs. Nevertheless, the groups differed significantly on preferences and beliefs related to love-object sex, residential proximity, ethnic background, physical intimacy, freedom from feelings of jealousy, sexual fidelity, emotional intimacy, and the importance of religious or legal acknowledgment.An early version of this paper was presented at the Annual Meeting of the National Council on Family Relations, in San Francisco, October 1984, Journal Series No. 2973 of the Hawaii Institute of Tropical Agriculture and Human Resources.  相似文献

In this study of 37 pre-therapy and 23 matched control families who never sought family therapy, father-child welfare affect and mother-child emergency affect were significantly higher in the control families. Control families were found generally to express more Welfare and Emergency emotion. Affective expression between parents did not significantly differentiate the groups.This study has been supported by Grant No. MA-4510 of the Medical Research Council of Canada and was presented at the annual meeting of the Canadian Psychiatric Association, Ottawa, Ontario, Canada, September 1983. The authors wish to express their thanks to Toby Schwartz, Harriet Gold-Kaats, and Terry Tannenbaum-Dascal, who acted as coders and research assistants; Joseph Beltempo, BSc, who helped in the statistical analysis; and James Robbins, PhD, who gave much valuable advice.  相似文献

Respiratory rate, respiration amplitude, and vocal responses were recorded in cats of different ages during classic conditioning. Vocal responses to the conditional stimulus (CS) appeared first in 8-week-old kittens, and became prominent at older ages. An increase in respiration rate occurred after the onset of the CS in cats of all ages. Similarly, the decrease of respiration amplitude was observed at all ages, but only in 8-week-old and older subjects did this response resemble an adult pattern. In 4-week-old kittens the response was characterized by an early and brief peak, suggesting an alpha conditional response (CR). Clear and significant discrimination between a warning and a safety signal was present in both respiratory and vocal responses after the age of 8 weeks.  相似文献

Mixed hyperactive/reading-disabled children, selected from a large sample of hyperactive children, were compared to pure hyperactive children on demographic, behavioral, and neuropsychological measures. Children in the Mixed group were reading-disabled relative to age and IQ; those in the Pure group had achievement scores that were average relative to age and IQ. The Mixed group was significantly older than the Pure group; there were no differences in gender, race, or socioeconomic status. Behaviorally, the groups did not differ significantly on teacher ratings or on psychiatric ratings of aggression. The Mixed group had a significantly higher Performance IQ, whereas the Pure group had a significantly higher Verbal IQ and performed better on measures of cognitive impulsivity. Several other measures failed to distinguish the groups. The data give minimal support to the notion that pure hyperactive and mixed hyperative/reading-disabled children constitute distinct subgroups of Attention Deficit Disorder with Hyperactivity.This research was supported in part by Mental Health Clinical Research Grant MH-30906 and by U. S. Public Health Service Grant MH-18579.  相似文献

The purpose of the present study was to investigate the influence of race (black, white) on the MMPI performance of alcoholic and nonalcoholic inpatients. Subjects were 73 (27 black, 46 white) male alcoholic inpatients and 73 (27 black, 46 white) male nonalcoholic psychiatric inpatients. While black and white alcoholics failed to differ on the MMPI, white alcoholics presented as less disturbed and black alcoholics as less defensive and distressed, compared to their respective nonalcoholic counterparts. Furthermore, only white alcoholics were accurately identified by the MMPI 2-4/4-2 high-point pair combination and only white alcoholics achieved more high-point pairs containing Scale 4 relative to nonalcoholic controls.  相似文献

The present study examined 8-12-year-old children's perceptions of parents' responses to sons and daughters experiencing interpersonal conflicts. In general, the children expected parents to respond in a manner consistent with traditional instrumental-expressive sex-role stereotypes. The implication of these findings for inadequacies in the socialization of interpersonal problem-solving styles in boys and girls is discussed.  相似文献
