This is a study of psychosocial outcomes of adolescents born to teenage mothers. Adolescents' problem behaviors, psychological well-being, social support, school variables, and sexual behaviors are compared across three groups—those born to mothers 17 or younger, mothers 18–19 years old, and mothers 20 or older. Analyses from two samples of African American adolescents from Maryland (n = 205) and Michigan (n = 570) are reported. The results from both samples indicate that mother's age at birth is unrelated to adolescents' psychosocial outcomes. These two studies add to the limited number of analyses that examine adolescent outcomes for children of teen mothers. The results suggest that efforts to understand social structural determinants of healthy and problematic adolescent development may be more informative than examining the effects of mother's age. They also suggest that teen pregnancy prevention programs may be more effective if they are part of a larger prevention strategy that incorporates social structural change efforts and not only a focus on individual level change. 相似文献

During summer, female meadow voles (Microtus pennsylvanicus) maintain territories and males do not engage in paternal care. As day length shortens, territories dissolve and males nest with females and young. Because paternal behavior has never been studied in free-living meadow voles during colder months or in the laboratory under short photoperiods, the authors examined whether males housed in short day (SD) lengths exhibited more frequent or better quality paternal behavior than males housed in long day (LD) lengths. Sexually and parentally inexperienced (naive) SD males exhibited proportionally more and qualitatively better paternal care than naive LD males. SD males were more responsive than LD males to classic social cues associated with prepartum aggression inhibition and paternal onset. SD sires also displayed qualitatively better paternal behavior than LD sires. These data suggest that meadow vole paternal state is regulated by specific social and environmental cues that may contain reliable information about ecological conditions that favor paternal care. 相似文献

One extreme or the other or perhaps the golden mean? Issues of spatial resolution in face processing
The findings of some of the key studies that have examined the contribution of different bands of spatial information, specified
in terms of cycles per face, to face recognition, and identification are reviewed. Based on findings from studies of low-,
high-, and band-pass filtering, it is concluded that neither low facial scales nor high facial scales are optimal. Instead,
a center range of facial scales, approximately 8-16 cycles per face, appears to make the greatest contribution to the recognition
process. A study of identification of band-pass filtered faces is reported that reinforces the view derived from the literature.
This indicated that a band with a harmonic mean of 11.1 cycles per face provided the most efficient recognition, with speed
and accuracy declining at lower and higher bands. 相似文献

Four studies tested the prediction that positive affect (PA) would relate more strongly to meaning in life (MIL) as a function of perceived time limitations. In Study 1 (N = 360), adults completed measures of PA and MIL. As predicted, PA related more strongly to MIL for older, compared to younger, participants. In Studies 2 and 3, adults (N = 514) indicated their current position in their life span, and rated their MIL. PA, whether naturally occurring (Study 2) or induced (Study 3), was a stronger predictor of MIL for individuals who perceived themselves as having a limited amount of time left to live. Finally, in Study 4 (N = 98) students completed a measure of PA, MIL, and future time perspective (FTP). Results showed that PA was more strongly linked to MIL for those who believed they had fewer opportunities left to pursue their goals. Overall, these findings suggest that the experience of PA becomes increasingly associated with the experience of MIL as the perception of future time becomes limited. The contribution of age related processes to judgments of well-being are discussed. 相似文献

The post-high school transition period is believed to be associated with considerable changes in social networks, yet longitudinal studies documenting these changes are scarce. To address this gap, the current research explored 3 relevant issues. First, changes in participants' relationship characteristics during the transition from high school were examined. Second, the roles of personality traits as antecedents of these changes were studied. Third, the association between change in relationship characteristics and personality during the transition was explored. A sample of over 2,000 German emerging adults, surveyed before leaving school and then 2 years after the transition from high school, was assessed on personality traits and a multidimensional assessment of the quality of their relationships. Findings indicated that participants experienced mostly positive changes in relationship quality during the transition from high school and that antecedent personality at school was an important predictor of the nature of this change. Finally, change in relationship quality was found to be associated with personality change during the post-school transition. Findings indicated that personality traits may influence transition success and that change in relationships during this transition may influence personality development. The implications of the research for post-school transition success are discussed. 相似文献

The current experiment investigated real three-dimensional (3D) objects with regard to performance on a mental rotation task and whether the appearance of sex differences may be mediated by experiences with spatially related activities. 40 men and 40 women were presented with alternating timed trials consisting of real-3D objects or two-dimensional illustrations of 3D objects. Sex differences in spatially related activities did not significantly influence the finding that men outperformed women on mental rotation of either stimulus type. However, on measures related to spatial activities, self-reported proficiency using maps correlated positively with performance only on trials with illustrations whereas self-reported proficiency using GPS correlated negatively with performance regardless of stimulus dimensionality. Findings may be interpreted as suggesting that rotating real-3D objects utilizes distinct but overlapping spatial skills compared to rotating two-dimensional representations of 3D objects, and real-3D objects can enhance mental rotation performance. 相似文献

This article calls for international comparative research on the professionalisation of Religious Education (RE). To this end, it provides a rationale for focusing upon the concept of professionalisation and a theoretical justification for international comparative research, particularly identifying its significance in terms of the development of RE in England and Germany. The article outlines a methodology for exploring the concepts of professional knowledge, professional self-organisation and politics and professional development. The proposed methodology involves a systematic analysis of primary documentary sources including: (1) academic and professional journal articles and textbooks; (2) the archives of relevant institutions and organisations; and (3) external evidence, such as inspection and research reports. An analytical case study of two leading journals in each national context, Religion in Education in England and Der Evangelische Erzieher in Germany, in the immediate post-war era is appended to illustrate the benefits of implementing such a methodology across national boundaries. 相似文献
