Little is known about the relationship between parent and child anxiety sensitivity (AS), particularly in nonclinical samples. The present study examined this association in 207 healthy parent-child pairs including 244 children (mean age = 12.3 years, 103 girls) and 226 parent figures (175 mothers). Sequential multiple linear regression revealed that parent AS was significantly associated with child AS in girls, but not in boys. Parent AS accounted for 9% of incremental variance in child AS, after controlling for child age, parent depression, and parent anxiety. Analyses of parent AS dimensions indicated that the social concerns dimension accounted for 14% of incremental variance in child AS in girls only. Parent anxiety and depression showed no association with child AS, once parent AS was taken into account. The findings indicate that parent AS, especially AS social concerns, demonstrates a significant relationship with child AS in this nonclinical sample of girls.  相似文献

In 2 experiments we assessed younger and older adults' ability to remember contextual information about an event. Each experiment examined memory for 3 different types of contextual information: (a) perceptual information (e.g., location of an item); (b) conceptual, nonemotional information (e.g., quality of an item); and (c) conceptual, emotional information (e.g., safety of an item). Consistent with a large literature on aging and source memory, younger adults outperformed older adults when the contextual information was perceptual in nature and when it was conceptual, but not emotional. Age differences in source memory were eliminated, however, when participants recalled emotional source information. These findings suggest that emotional information differentially engages older adults, possibly evoking enhanced elaborations and associations. The data are also consistent with a growing literature, suggesting that emotional processing remains stable with age (e.g., Carstensen & Turk-Charles, 1994, 1998; Isaacowitz, Charles, & Carstensen, 2000).  相似文献

National bioethics commissions have struggled to develop ethically warranted methods for conducting their deliberations. The National Bioethics Advisory Commission in its report on stem cell research adopted an approach to public deliberation indebted to Rawls in that it sought common ground consistent with shared values and beliefs at the foundation of a well-ordered democracy. In contrast, although the research cloning and stem cell reports of the President's Council on Bioethics reveal that it broached two different methods of public deliberation--balancing goods and following an overarching moral principle--it adopted neither. Thereupon its primer mover, Leon Kass, influenced particularly by the approach of Leo Strauss, sought to develop a method of public deliberation guided by tradition and practical wisdom. When this failed, the Council fell back on a method that took account of shared fundamental values of a free democracy--a method remarkable akin to that employed by the National Bioethics Advisory Commission. Respect for diverse reasonable conceptions of the good in a democratic polity requires national bioethics commissions to seek and incorporate that which is valuable in opposing positions.  相似文献

This article aligns the symbolism of the long (/i/) and short (/I/) e sounds in English with the two dimensions of emotional space-Pleasantness and Activation. On the basis of this alignment, the four quadrants of emotional space are labelled Cheerful (high /i/, high /I/), Cheerless (low /i/, low /I/), Tough (low /i/, high /I/), and Tender (high /i/, low /I/). In four phases, data from over 50 samples (mainly, poetry, song lyrics, and names) were plotted and compared in terms of their use of the two e sounds. Significant and meaningful differences among samples were discovered in all phases. The placement of samples in quadrants was additionally informative. Data samples including many long e sounds (/i/) tended to be more Pleasant and those including many short e sounds (/I/) tended to be more Active.  相似文献

Two studies of Puerto Rican youths' development on the U.S. mainland examined the consequences of perceived racial/ethnic discrimination on mental health. In Study I, children were found to have a low likelihood of perceiving discrimination, whereas in Study 2, nearly half of the adolescent sample reported perceiving racial/ethnic discrimination. Although both groups scored high on multiple indicators of mental health, perceiving discrimination and worrying about discrimination were negatively associated with some dimensions of self-esteem and positively associated with depression and stress. Adolescents were aware of negative stereotypes about Puerto Ricans, and nearly half of them related discriminatory instances. Results suggest that both perceiving discrimination and anxiety regarding discrimination can serve as risk factors for the mental health of this population.  相似文献

The role of interference in memory span   总被引:10,自引:0,他引:10  
In two experiments, we investigated the possibility that susceptibility to proactive interference (PI) affects performance on memory span measures. We tested both younger and older adults (older adults were tested because of the suggestion that they are differentially susceptible to PI). We used two different span measures and manipulated testing procedures to reduce PI for these tasks. For older adults, span estimates increased with each PI-reducing manipulation; for younger adults, scores increased when multiple PI manipulations were combined or when PI-reducing manipulations were used in paradigms in which within-task PI was especially high. The findings suggest that PI critically influences span performance. We consider the possibility that interference-proneness may influence cognitive behaviors previously thought to be governed by capacity.  相似文献

The authors surveyed 86 pregnant women (73%White, 8% Asian, 7% African American, 6% Hispanic, and1% Native American) to examine individual andorganizational factors associated with organizationalcommitment and planned timing of their maternity leavesand return to work after childbirth. Women whoseorganizations offered guaranteed jobs after childbirthplanned to work later into their pregnancies and toreturn to work sooner after childbirth. Women whoperceived supportive work-family cultures were morecommitted to their organizations and planned to returnmore quickly after childbirth than women who perceived less supportive cultures. Also, women with lesstraditional attitudes toward parenting planned to worklater into their pregnancies and return to work soonerafter childbirth.  相似文献

The Roho, or Holy, Spirit churches of Nyanza Province in Western Kenya spring from a charismatic Christian movement that emerged among the Luo during the colonial era. This article uses life narratives of active Roho participants to counter-balance existing historical literature which draws heavily on colonial records. Oral sources call into question the ‘top-down’ paradigm of schism that has dominated the discussion of African independent Christianity and emphasize the role of women in the evolution and expansion of the Roho church. This article also traces the gradual transformation of women’s involvement from the early years when—incorporating indigenous patterns of female spirit mediumship—women acted as soldiers and pastors to the present condition of Western-style institution and limited leadership opportunities for women.  相似文献
