A distinct type of phenomenon that has not been previously noted as such is named and described. Men who present a two-woman phenomenon retain a commitment to wife and marriage while loving another woman. Conflict arises only when one of the women has to be relinquished. It is postulated that many men with this pattern of loving have experienced a traumatic childhood and an oedipal conflict which defensively involved two maternal objects in fantasy or reality. One mother was hated, the other loved. This dynamic is one possible determinant leading to the two-woman phenomenon.  相似文献

Investigating the specific of psychic performance disorders in epileptics structural aspects in addition to quantitative performance differences are considerable. We compared psychometrically obtained performance structures of epileptic children and adults and of parallelised healthy control persons. It became evident, that the performance differentiation hypothesis is to corroborate also in epileptic patients. The psychic performance structure of epileptics is characterized by a lower differentiation level of the basis functions underlining the performances. Our factor analytic investigations emphasize the importance of deceleration of psychic/psychomotoric speed in epileptics as primary basic disorder.  相似文献

Intrathecal methotrexate-overdosage in the meningosis therapy leads to CNS damages dependent on dose. It was given a own case report and a literature review with clinical symptoms and the therapy in this complication. Neuropathologic findings included demyelinisation und necrosis of the white matter.  相似文献

In this study we investigated the immediate and continued impact on women of a major stressful event, the outcome of pregnancy, and the mitigating effect of self-esteem and intimacy with their spouse on their reactions. Few other studies have investigated initial reactions to crisis events. Ninety-nine Israeli women who experienced either normal delivery or pregnancy complications were interviewed at the time of the event and 3 months later. High self-esteem was found to limit feelings of depression at both times. Intimacy with spouse limited depression at the event, but not at follow-up. High self-esteem was seen as always being exploitable by women who possessed it, whereas the benefit of intimacy with spouse was seen as being dependent on situational demands and environmental constraints. Cross-cultural implications were presented.  相似文献

Recipient's mood, relationship type, and helping   总被引:6,自引:0,他引:6  
We conducted two studies to examine how a potential helper is affected by having a communal orientation toward a relationship with a potential recipient and by the potential recipient's sadness. We hypothesized that (a) having a communal orientation would increase helping and that (b) people high in communal orientation, but not others, would respond to a potential recipient's sadness by increasing helping. These hypotheses were tested in two studies. In Study 1, individual differences in communal orientation toward relationships were measured by using a new communal orientation scale reported for the first time in this article. In Study 2, manipulations were used to lead subjects to desire either a communal or an exchange relationship with another person. In both studies, subjects were exposed to a sad person or to a person in a neutral mood whom they were given a chance to help. As hypothesized, in both studies communally oriented subjects helped the other significantly more than did others. Also as hypothesized, in both studies communally oriented subjects but not others, increased helping in response to the other person's sadness although this effect reached statistical significance only in the second study.  相似文献

Two studies are reported on a new Anger Control Inventory based on a cognitive-behavioral person-situation interaction model. In Study 1, the inventory responses of 118 clinical subjects and 190 normal subjects were correlated with an anger problem criterion based on observable signs. Factor analyses were conducted to clarify the construct base of the inventory. In Study 2, comparisons were made between the inventory responses of 100 spouse batterers and 96 normal subjects. Significant differences between the pretreatment and posttreatment scores of 65 batterers given treatment in anger control were obtained on the inventory scales, which were found to be correlated with the problem criterion and discriminating between the clinical and normal groups. The construct validity and clinical utility of the Anger Control Inventory are discussed.  相似文献

Qualitative studies have noted that individuals with "borderline" psychopathology exhibit extreme thought disorder on unstructured tests, yet manifest relatively normal performance on more structured tests of cognitive performance. The present study provides empirical support for this clinical observation. Borderline syndrome patients, defined by DSM-III criteria for borderline personality disorder and/or schizotypal personality disorder, demonstrated significantly greater thought disorder on the Rorschach, as measured by Johnston and Holzman's (1979) Thought Disorder Index (TDI), than did nonpsychiatric controls and were indistinguishable from patients with schizophrenic disorder of relatively recent onset. Borderline patients did not differ from controls on a structured test of cognitive slippage. Further examination of the role of structure in the assessment and treatment of borderline syndrome disorders seems warranted.  相似文献
