We explored the phenomenon of the transition to adulthood, focusing on how young people cope with various developmental tasks in relation to their expectations, future projects, fears and indecision in two Italian regional areas characterized by different trends in youth employability, higher educational attainment and family formation process. We measured self-perceived adulthood, self-reported satisfaction, independence, perceived support regarding personal relationships and practical and economical issues, personal projections and future life’s choices. We also explored the perception of self-fulfillment for the future concerning personal goals in life, such as in the spheres of work, studies and economic autonomy together with expectations for the quality of personal relationships. One hundred and sixty nonworking university students (M age = 22.6; SD = 2.77; range = 19–35) from the Universities of Turin and Palermo took part in this study. Sub-groups differed on self-perceived adulthood, self-reported satisfaction, independence, perceived support and self-fulfillment. Psychological and economic independence from the family of origin was most perceived by the participants from Turin who reported a higher degree of satisfaction regarding their choice of studies and their future perspective of self-fulfillment at work. Young people from Palermo highlighted personal relationships as an important source of perceived support.  相似文献

A key tenet of feature integration theory and of related theories such as guided search (GS) is that the binding of basic features requires attention. This would seem to predict that conjunctions of features of objects that have not been attended should not influence search. However, Found (1998) reported that an irrelevant feature (size) improved the efficiency of search for a Color × Orientation conjunction if it was correlated with the other two features across the display, as compared to the case in which size was not correlated with color and orientation features. We examined this issue with somewhat different stimuli. We used triple conjunctions of color, orientation, and shape (e.g., search for a red, vertical, oval-shaped item). This allowed us to manipulate the number of features that each distractor shared with the target (sharing) and it allowed us to vary the total number of distractor types (and, thus, the number of groups of identical items: grouping). We found that these triple conjunction searches were generally very efficient—producing very shallow Reaction Time × Set Size slopes, consistent with strong guidance by basic features. Nevertheless, both of the variables, sharing and grouping, modulated performance. These influences were not predicted by previous accounts of GS; however, both can be accommodated in a GS framework. Alternatively, it is possible, though not necessary, to see these effects as evidence for “preattentive binding” of conjunctions.  相似文献

This article describes a study of 136 female intimate partner violence victims living in poverty in Nicaragua. The paper aimed to analyze the relationship between experiencing stressful life events (SLE) and perceived social support with suicide attempts, and to evaluate the differences in the SLE experienced by female suicide attempters versus non‐attempters. The results showed the existence of a high level of SLE among the interviewees, and that women who have attempted suicide have experienced substantially more of these events. Experiences of violence and less social support were especially related to suicide attempts among the interviewees.  相似文献

Belief in life after death offers potential comfort in the face of inevitable death. However, afterlife belief likely requires not only an awareness of death but also body–self dualism—the perception that the self (e.g., the mind) is distinct from the physical, undeniably mortal, body. In turn, we hypothesized that mortality salience (MS) should heighten afterlife belief only when dualism is facilitated. Study 1 found that MS increased belief for people high, relative to low, in trait mind–body dualism. In Study 2, MS only increased belief when people first wrote about their thoughts and personality, which a pilot study confirmed facilitated dualistic belief, relative to thinking about the physical self. Study 3 used the brain–computer interface technology to induce a dualistic experience: MS increased belief when participants accurately “typed” without the use of their external body (i.e., no hands). Together, these findings support the position that mortality awareness and body–self dualism constitute a “why” and “how” of afterlife belief. Copyright © 2015 John Wiley & Sons, Ltd.  相似文献

Social integration is fundamental to health and well‐being. However, few studies have explored how neighborhood contexts pattern types and levels of social integration that individuals experience. We examined how neighborhood poverty structures two dimensions of social integration: integration with neighbors and social integration more generally. Using data from the United States Third National Health and Nutrition Examination Survey, we linked study participants to percent poverty in their neighborhood of residence (N = 16,040). Social integration was assessed using a modified Social Network Index and neighborhood integration based on yearly visits with neighbors. We fit multivariate logistic regression models that accounted for the complex survey design. Living in high poverty neighborhoods was associated with lower social integration but higher visits with neighbors. Neighborhood poverty distinctly patterns social integration, demonstrating that contexts shape the extent and quality of social relationships.  相似文献

This special section addresses a gap area of resilience and LGBT well‐being. Although comprehensive global diversity regarding LGBT resilience was challenging to find, the special section includes representation from outside the US (Israel and Hong Kong), ethnic/racially diverse domestic populations, immigration, and one population for which LGBT identities might be considered marginalized—Christians in the US. The full range of LGBT identities are represented in the issue along with persons identifying as queer or questioning, although transgendered people were less well represented than lesbian, gay or bisexual identities.  相似文献
