Eye movement behaviour in hand-eye tasks suggests a preference for a “just in time” processing strategy that minimizes the use of working memory. In the present study, a scene comparison task was introduced to determine whether the preference holds when the task is primarily visual and when more complex naturalistic scenes are used as stimuli. In two experiments, participants made same or different judgements in response to simultaneously presented pairs of scenes that were identical or differed by one object. The number of fixations per scene glance and the number of fixations intervening between glances to corresponding objects suggest that frequently one object at a time is encoded and maintained in visual working memory. The same pattern of results was observed in a third experiment using word and object arrays. Overall, the results suggest a strong general bias toward minimal use of visual working memory in complex visual tasks.  相似文献

This paper examines three medical student poems about death to explore how medical students use poetry to understand their encounters with dying patients and to discuss how these poems function as elegies in the context of medical culture.  相似文献

Recognition probes given before or after a series of letters presented at varying rates were used to evaluate perception and memory loss of order and item information. For both order and item information pre- and postprobe functions converged at fast rates of presentation. Performance decrement at fast rates is attributable to perceptual factors and is greater for order than for item information.  相似文献

Significant associations between childhood adversity and adult mental health have been documented in epidemiological and social science research. However, there is a dearth of research examining this relationship among black Americans, as well as into what cultural institutions and practices may help individuals in dealing with childhood adversity. This study suggests that religion may be an important resource for black Americans in the face of early‐life socioeconomic and health disadvantage. Using data from the National Survey of American Life, a nationally representative sample of both African Americans and black Caribbeans (n = 5,191), this study outlines a series of arguments linking childhood adversity, religiosity, and self‐perception among black Americans. The results suggest some support for religious involvement in moderating—or buffering—the harmful effects of childhood adversity on the self‐esteem and mastery among black Americans, specifically religious service attendance and religious coping. In addition, the results reveal that religion may also amplify the deleterious effects of childhood disadvantage on adult mental health. Study limitations are identified and several promising directions for future research are discussed.  相似文献

Limited research has explored how specific elements of physical and social environments influence mental health indicators such as perceived stress, or whether such associations are moderated by gender. This study examined the relationship between selected neighborhood characteristics and perceived stress levels within a primarily low‐income, older, African‐American population in a mid‐sized city in the Southeastern U.S. Residents (n = 394; mean age=55.3 years, 70.9% female, 89.3% African American) from eight historically disadvantaged neighborhoods completed surveys measuring perceptions of neighborhood safety, social cohesion, aesthetics, and stress. Multivariate linear regression models examined the association between each of the three neighborhood characteristics and perceived stress. Greater perceived safety, improved neighborhood aesthetics, and social cohesion were significantly associated with lower perceived stress. These associations were not moderated by gender. These findings suggest that improving social attributes of neighborhoods may have positive impacts on stress and related benefits for population health. Future research should examine how neighborhood characteristics influence stress over time.  相似文献

Greater understanding of how residential stability affects child separation and reunification among homeless families can guide both child welfare and homeless policy and practice. This article draws upon two longitudinal studies examining services and housing for homeless families and their relationship to family and housing stability. Both studies were conducted in the same state at roughly the same time with similar instruments. The first study, examining families’ experiences and outcomes following entry into the homeless service system in three counties in Washington State, found that at 18 months following shelter entry, families that are intact with their children were significantly more likely to be housed in their own housing (46%) than families that were separated from one or more of their children (31%). The second study, a quasiexperimental evaluation of a supportive housing program for homeless families with multiple housing barriers, found that the rates of reunification for Child Protective Services (CPS)‐involved families receiving supportive housing was comparable to that for families entering public housing without services, but significantly higher than the rate of reunification for families entering shelter. Taken together, the findings from both studies contribute to the evidence underscoring the importance of housing assistance to homeless families involved in the child welfare system.  相似文献
