This study examines the relationship of life stress, daily hassles, and perceived self-efficacy to adjustment in a community sample of 32 men and 32 women between ages 65 and 75. In a structured interview, negative life change events, daily hassles, self-efficacy, depression, psychosomatic symptoms, and negative well being were assessed. Both negative life events and daily hassles were related to psychological distress and physical symptoms for men, and hassles were associated with psychological distress and physical symptoms for women. An inverse relationship between self-efficacy and maladjustment was also found. Hassles showed the most powerful relationship to distress.  相似文献

Adults are better at recognizing familiar faces from the internal facial features (eyes, nose, mouth) than from the external facial features (hair, face outline). However, previous research suggests that this “internal advantage” does not appear until relatively late in childhood, and some studies suggest that children rely on external features to recognize all faces, whether familiar or not. We use a matching task to examine face processing in 7-8- and 10-11-year-old children. We use a design in which all face stimuli can be used as familiar items (for participants who are classmates) and unfamiliar items (for participants from a different school). Using this design, we find an internal feature advantage for matching familiar faces, for both groups of children. The same children were then shown the external and internal features of their classmates and were asked to name or otherwise identify them. Again, both age groups identified more of their classmates correctly from the internal than the external features. This is the first time an internal advantage has been reported in this age group. Results suggest that children as young as 7 process faces in the same way as do adults, and that once procedural difficulties are overcome, the standard effects of familiarity are observed.  相似文献

Despite this virtue's history as an instrument of women's oppression, modesty, at its most basic, means voluntary restraint of one's power, undertaken for the sake of others. It is a mechanism that modifies unequal power relationships and encourages greater compassion and fairness. I use a Christian perspective with influences from Jewish and Muslim sources to examine modesty. The modest person, I argue, must be in relationship with others, must be honestly aware of her impacts on others, must be sensitive to those impacts, compassionate toward others, and willing to hold back for others' sakes. Moreover, modesty is not only a virtue that pertains to sexuality and clothing, but it also can promote virtuous environmental behavior, particularly as it leads to awareness of, and sensitivity to, the effects of everyday behaviors on vulnerable others.  相似文献
