This paper focuses on prosocial and altruistic behavior in late life. Empirical data on prevalence of helping behaviors among the elderly and the range of motives underlying their helping are reviewed. The authors consider implications of these data for theories of social behavior in late life. Questions are raised regarding the universal applicability of models of social behavior which have been implicit in much of existing research in social gerontology. Data on helping by the elderly are related to dependency and autonomy models of social interaction. Futhermore, the potential for altruistic as opposed to extrinsic motivations for helping among older adults is considered, challenging the exclusive reliance on exchange principles for understanding social interactions by older persons. Empirical evidence of prosocial behavior in late life is placed in the context of life-span developmental theories of personality and a contributory model of late life social behavior is proposed. 相似文献

3 recent studies about the relative effects of family planning and development are reviewed in an effort to point out their limitations and to augment them. A tentative theoretical framework is presented from which the problem of fertility reduction may be viewed. Also presented is an analysis of the "outliers" in 1 of the 3 studies. This analysis involves consideration of macrosocial and contextual aspects of different nations as a supplement to other analyses. Mauldin and Berelson (1978) and Tsui and Bogue (1978) used indicators of social setting and family planning effort to explain declines in, respectively, crude birthrate between 1965 and 1975, and total fertility rates between 1968 and 1975. The 2 studies used nearly identical sets of explanatory variables. With both studies using the same indicators, except for "labor force," it is not surprising that the results were the same. The results were previously obtained by Freedman and Berelson (1976), who also used the Lapham Mauldin index of planning effort along with similar indicators of social setting. Freedman and Berelson found that birthrate declines could be explained better by program effort (which independently explained 17% of the variance in crude birthrate (CBR) declines) than by social setting (which independently accounted for 7% of that variance), and that the 1972 birthrate itself was similarly explained (15% of the variance attributed to program effort alone, 5% to social setting alone). Mauldin and Berelson obtained nearly identical results. In the Tsui and Bogue study, the contribution of the 1968 level of fertility was the dominant influence on the 1975 total fertility rate. The standardized regression coefficient indicated that previous fertility explained 50-60% of subsequent fertility by direct relationship, a figure comparable to the social setting family planning interaction effects (44-58%) in the 2 other studies. Much of this discussion is devoted to an analysis of the "outliers" in the exploratory data analysis done by Sykes for Mauldin and Berelson (1978). The outliers in Sykes' exploratory data analysis were divided along 2 dimensions. The first involves the relationship between predicted and actual reductions in fertility. The 2nd dimension refers to the independent variables used to predict the fertility declines. This analysis involves analysis of contextual variables and an analysis of distributional variables. It is limited by missing data, but the analysis of Freedman and Berelson (1976), Mauldin and Berelson (1978), and Tsui and Bogue (1978) is plagued by missing variables: contextual variables; distributional variables; and unique national, regional, or local circumstances. These can only be adequately revealed by case studies and may be important influences on fertility behavior. Effects of family planning and social setting may be conditioned by contextual variables (e.g., island status as in Taiwan), or unique circumstances (e.g., coercion as in India), and distribution appears to have an effect of its own. 相似文献

Menarche has been considered a marker for examining interindividual differences in biobehavioral development and for separating pubertal development into 2 stages. The purpose of this study was (1) to compare hormone concentrations in pre- and postmenarcheal girls to determine whether they fit a continuous or dichotomous model of pubertal development surrounding menarche; and (2) to address methodological issues of variability in self-reports of menstrual histories and reliability in reporting age at menarche. Girls (N = 52) ages 9 to 14 years were enrolled in a longitudinal study. Blood was drawn for hormone concentrations. Menstrual-cycle information was collected by questionnaire and oral report. Discrepancies in reporting of age at menarche ranged from 0 to 18 months and variability was noted in length of cycle. There was great overlap in hormones between pre- and postmenarcheal categories. Future studies might consider menarche as the culmination of underlying developmental processes rather than as a discrete event. Limitations of each measure of puberty should be considered by investigators conducting biobehavioral studies of adolescents. 相似文献

In Experiment 1, we videotaped elderly and younger adults (n = 69) reporting their memories for a crime video. The seniors were significantly less accurate than the younger adults. In Experiment 2, participants viewed the testimony videotapes and rated the elderly as less credible than the younger adults. In Experiment 3, participant-jurors (n = 302) evaluated transcribed testimonies provided by Experiment 1 participants. The ostensible age of the witnesses was manipulated. Thus, some participants read a senior's testimony believing it was provided by a younger adult and vice versa. Participants were apparently not biased by negative stereotypes of seniors' eyewitness capabilities. 相似文献

Theorists have variously defined what it means to be a good citizen. But how do citizensthemselves views their responsibilities? And is there any relationship between a person's view of citizenship and his or her political participation? This paper uses a combination of methods to explore these issues. A Q method study reveals four citizenship perspectives that provide evidence for striking differences in how people define the participatory responsibilities of a good citizen. An exploratory survey analysis finds that the four citizenship perspectives are significantly related to political behavior, even when socioeconomic status and attitudinal variables related to participation are controlled. While adding to our understanding of participation, these findings also underscore the importance of investigating the conceptualizations of citizens to gain more complete understandings of how political systems work. 相似文献
