Little research has directly addressed the role of gender in perceptions of self vs. partner's contributions to a relationship, despite the fact that partners in heterosexual relationships often disagree about whether their relative contributions result in an equitable relationship [N. W. VanYperen and B. P. Buunk (1990), A Longitudinal Study of Equity and Satisfaction in Intimate Relationships, European Journal of Social Psychology,Vol. 20, pp. 287–309]. The primary purpose of this investigation was to systematically examine the association between gender and the perceived value of several different types of contributions made by each partner to a committed relationship. We considered both the gender of the perceiver and the source of the contributions (self vs. partner). A sample of 212 men and 348 women (most of whom were college students; 87% white) were asked to judge the value of their own and their partner's hypothetical contributions to a marital or long-term cohabiting relationship. The results indicated that men and women generally agreed about the value of the contributions made by themselves and their partners. However, gender differences in the perceived value of many contributions depended on whether the contribution was made by self or partner (e.g., men attributed more worth to their partner's sexual faithfulness than to their own, whereas women believed that both partners should receive equal value for this contribution). These perceptual differences suggest that at times it may be difficult for partners to agree about the equity of their ongoing relationships. Special gratitude goes to Pepper Schwartz for her contributions to an earlier draft of the paper. The authors also wish to thank Elaine Hatfield and Alicia Thompson for their comments on an earlier draft of the paper and Dennis Johnson who contributed to the idea for the study.  相似文献

To determine if a detailed analysis of the language items of the Bayley Scales of Infant Development (BSID) would be useful in detecting language delay, the Bayley Mental Development Index (MDI) and Reynell Developmental Language Scales (RDLS-R) were administered to 137 low-birthweight infants at 2 years of age. In spite of scores in the normal range on the BSID, many of these children had significantly delayed language. However, the children with delayed language could be detected on the basis of detailed analysis of certain language items of the MDI, indicating that these items are more useful than the total MDI score.  相似文献

The role of gender and ethnicity as status variables, i.e., as cues to social standing, personal experiences, and cultural expectations, is discussed and the relevant literature is reviewed. The point is made that gender research typically fails to include race/ethnic concerns, and that studies of ethnic groups often ignore gender issues. Consideration is given to the relative scarcity of research which deals with both gender and race/ethnic issues. The impact of each variable, gender and race, is examined separately, and in combination. Issues of racism and sexism are specifically addressed, and the need for research which utilizes an interaction approach is presented. An overview of the articles presented in this special issue is provided. They are discussed in terms of their ability to confirm the importance of the gender/ethnic interaction.  相似文献

Semantics are given for modal extensions of relevant logics based on the kind of frames introduced in [7]. By means of a simple recipe we may obtain from a class FRM (L) of unreduced frames characterising a (non-modal) logic L, frame-classes FRM (L.M) characterising conjunctively regular modal extensions L.M of L. By displaying an incompleteness phenomenon, it is shown how the recipe fails when reduced frames are under consideration.  相似文献

The present study was aimed at replicating the results of a previous work on sex differences and electrodermal asymmetry from our laboratory (Román,et al. 1987). Skin conductance was bilaterally recorded in a sample of 44 dextral volunteers (22 males and 22 females) during a stimulus-free period, and the performance of two tasks (verbal and spatial). Subjects were grouped into two groups of right-hand and left-hand dominance in their electrodermal responses (EDRs) in accordance with their laterality coefficient scores at rest. During the tasks subjects appeareed clearly differentiated by their lateralization in the magnitude and frequency of EDRs independently of gender: right-hand responders showed higher electrodermal activity on their right hand, while left-hand responders showed higher electrodermal activity on their left hand. Sex differences were not observed within each responsiveness pattern. The orientation of phasic electrodermal changes remained constant throughout the different conditions.  相似文献

In an attempt to replicate several previous studies, a reversal design was used to assess the effects of publicly posted feedback on vehicle speed reduction. The intervention phases consisted of daily posted feedback that supplied drivers with either accurate or inaccurate information regarding the percentage of vehicles exceeding the speed limit on the road. Results from the two feedback conditions indicated no speed reduction in comparison to baseline levels. These results are discussed in light of previous studies that found strong effects for such feedback. Baseline levels of driver compliance and methodological differences may limit the effectiveness of posted feedback in reducing speeding.  相似文献

An application of the foot in the door technique to organ donation   总被引:1,自引:0,他引:1  
The extent to which the size of an initial request related to organ donation could be reduced when using the foot-in-the-door technique was investigated. After being asked to comply with an initial request to complete a questionnaire related to organ donation having either 5, 10, 15, or 20 items or not being asked to complete the questionnaire, subjects indicated their willingness to become an organ donor. In addition to replicating earlier research, the results indicated that the original 20-item questionnaire could be reduced to five items without losing its effectiveness to increase willingness to become an organ donor when compared to the no-request condition. The implications of the foot-in-the-door technique for medical volunteering in general and suggestions for future research are also discussed.  相似文献

Unique developmental crises in old age may lead to social withdrawal that negatively affects the individual and his/her marital and family relationships. Without an awareness of these aging dynamics, the therapist can inadvertently perpetuate these distancing behaviors which can exacerbate marital and family conflict. This paper discusses certain developmental crises which can result in increased isolation for the older adult, and suggests therapeutic interventions to facilitate increased closeness among family members.  相似文献
