Mark P. Jensen 《Sex roles》1987,17(5-6):253-267
The observation that men are usually more supportive of war than women had led several authors to suggest that masculinity plays a causal role in the decision to make war and stockpile nuclear arms. In order to examine the relationship between sex role orientation and attitudes towards war and nuclear weapons, gender and measures of sex role orientation were used to predict three attitudes about nuclear weapons and the use of military force. Two specific and two classes of hypotheses regarding the possible relationships among these variables were tested: masculinity, femininity, Masculinity × Femininity interaction, and Gender × Sex Role Orientation hypotheses. The results provided limited support only for the femininity hypothesis—that attitudes toward war are associated with feminine traits. However, neither masculinity nor femininity was found to be the only mediators of the gender/war attitude relationship, indicating that sex role orientation (and especially masculinity) should be given less emphasis when trying to explain the relationship between gender and attitudes toward war.The author gratefully acknowledges the helpful comments of Douglas Kenrick, Nancy Russo, and an anonymous reviewer on a earlier version of this paper. 相似文献

The marriage role expectations of female university students enrolled in an introductory marriage and family course at the University of Kentucky in 1961 (N=72), 1972 (N=58), 1978 (N=115), and 1984 (N=81) were compared. The 1972 group was found to be significantly more egalitarian than the 1961 group in overall marriage role expectations and on all subscales except authority. The 1978 and 1984 groups were significantly more egalitarian than the 1961 group on overall marriage role expectations and on all seven of the subscales: authority, homemaking, child care, personal characteristics, social participation, education, and employment and support. The 1978 group was significantly more egalitarian than the 1972 group only on authority and homemaking, with no significant differences on the other five subscales or on overall role expectation score. The 1984 group was significantly more egalitarian than the 1972 group only on authority, homemaking, and child care, and was slightly (not satistically significant) more traditional on personal characteristics and social participation. There were no significant differences between the 1978 and 1984 groups on overall expectation or on any of the subscales. In fact, the 1984 group was slightly more traditional on homemaking, personal characteristics, social participation, employment and support, and overall expectations. The data from this study showed the greatest gain in egalitarian trends to be between 1961 and 1972, with a continuation of the trends at a somewhat slower rate of change between 1972 and 1978, and a discontinuation of the trend toward more egalitarian expectations between 1978 and 1984.The data were collected in February 1961, January 1972, September 1978, and September 1984. Special acknowledgement and appreciation are expressed to Jessie Ringo (retired), University of Kentucky, for making the 1961 data available for this study. 相似文献
