This review considers Margaret Miles’s recent book, offering some criticisms of specific points but overall admiring the lucidity and passion Miles brings to her reading of Augustine.  相似文献

This study focused on the negative reactions of older women with osteoarthritis to the receipt of instrumental support (i.e., physical assistance) from their husbands and the effects of such negative reactions on the women's psychological well-being and self-care. Applying a person-environment fit model, the authors predicted that women's negative reactions to spousal support would be determined by the fit between this support and the personal centrality (importance) of being functionally independent. Consistent with this prediction, women who received high levels of support from the husband and for whom being functionally independent was not highly central reacted less negatively to this support. More negative reactions to spousal support were related to greater concurrent depressive symptomatology and fewer self-care behaviors. In addition, negative reactions were predictive of the women's increased depressive symptomatology and decreased life satisfaction. Findings illustrate a useful theoretical approach to the examination of support from family caregivers.  相似文献

The relationships of epidemiological (objective) risk indices, perceived disease characteristics, and cognitive heuristics to women's perceived susceptibility to breast cancer, heart disease, and osteoporosis in a community sample of 312 women ages 40-86 were examined. Epidemiological indices accounted for a small to moderate proportion of the variance in perceived susceptibility. Psychological factors (perceived similarity to women who contract the target disease and perceived disease prevalence) predicted perceived susceptibility above and beyond medical risk factors. Opposite to actual risk, age correlated negatively with perceived susceptibility to all 3 diseases. Exploratory analyses suggested that perceived similarity, perceived prevalence, and absent/exempt beliefs might mediate this relationship. Confirmatory factor analyses verified that measures of absolute and direct comparative risk assess the same underlying construct of perceived susceptibility.  相似文献

The relation between heart-rate deceleration and the expression of positive affect in infancy is examined by testing the hypothesis that intensity of orienting (as indexed by heart-rate deceleration) is predictive of intensity of positive affect (smile size and duration). A social-stimulation procedure was utilized to elicit smiles in 41 3-month-old infants. The first smile elicited was coded for smile size and duration, and the preceding heart-rate deceleration was coded for magnitude, duration, and slope of deceleration. Slope and duration of heart-rate deceleration proved to be reliable predictors of smile size, but none of the heart-rate measures correlated with smile duration. Results suggest that the steeper and more rapid the deceleration, the larger the ensuing smile. Possible mechanisms for this finding are discussed.  相似文献
