The capability to remember and execute intentions in the future – termed prospective memory (PM) – may be of special significance for older adults to enable successful completion of important activities of daily living. Despite the importance of this cognitive function, mixed findings have been obtained regarding age-related decline in PM, and, currently, there is limited understanding of potential contributing mechanisms. In the current study, older (N=41) and younger adults (N=47) underwent task-functional MRI during performance of PM conditions that encouraged either spontaneous retrieval (Focal) or sustained attentional monitoring (Non-focal) to detect PM targets. Older adults exhibited a reduction in PM-related sustained activity within the anterior prefrontal cortex (aPFC) and associated dorsal frontoparietal cognitive control network, due to an increase in non-specific sustained activation in (no-PM) control blocks (i.e., an age-related compensatory shift). Transient PM-trial specific activity was observed in both age groups within a ventral parietal memory network that included the precuneus. However, within a left posterior inferior parietal node of this network, transient PM-related activity was selectively reduced in older adults during the non-focal condition. These age differences in sustained and transient brain activity statistically mediated age-related declines in PM performance, and were potentially linked via age-related changes in functional connectivity between the aPFC and precuneus. Together, they support an account consistent with the Dual Mechanisms of Control framework, in which age-related PM declines are due to neural mechanisms that support proactive cognitive control processes, such as sustained attentional monitoring, while leaving reactive control mechanisms relatively spared. 相似文献

Research on the importance of complete mental health has led to increased focus on students' subjective well-being (i.e., happiness and life satisfaction) coupled with the traditional attention to psychopathology. Although screeners for psychopathology abound, the present project is novel in applying best practices in universal screening to grade level-wide assessment of children's life satisfaction, followed by implementation of a positive psychology intervention for students identified through the screener. In this case study of 375 third- to fifth-grade students in one elementary school, 93.6% participated in the screening, 11.2% qualified for supplemental services based on screening cutoff scores, and 4.8% took part in the targeted intervention to improve subjective well-being. Repeated measures analysis of mean scores revealed the intervention increased children's life satisfaction, lending support for the value of universal screeners in the process of service delivery. Implications for practice regarding universal screening and intervention for life satisfaction are discussed. 相似文献

Previously depressed individuals experience disturbances in affect. Affective disturbances may be related to visual mental imagery, given that imagery-based processing of emotional stimuli causes stronger affective responses than verbal processing in experimental laboratory studies. However, the role of imagery-based processing in everyday life is unknown. This study assessed mental imagery in the daily life of previously and never depressed individuals. Higher levels of visual mental imagery was hypothesised to be associated with more affective reactivity to both negatively and positively valenced mental representations.This study was the first to explore mental imagery in daily life using experience sampling methodology. Previously depressed (n?=?10) and matched never depressed (n?=?11) individuals participated in this study. Momentary affect and imagery-based processing were assessed using the “Imagine your mood” smartphone application. Participants recorded on average 136 momentary reports over a period of 8 weeks.The expected association between visual mental imagery and affective reactivity was not found. Unexpectedly, in both previously and never depressed individuals, higher levels of imagery-based processing of mental representations in daily life were significantly associated with better momentary mood and more positive affect, regardless of valence.The causality of effects remains to be examined in future studies. 相似文献

The present study explored the experience and understanding of gender for gay and queer men who perform drag. It is part of a 20-year program of research focused on how LGBTQ gender identities arise, why they coalesce, and how they are enacted within their social contexts. Interviewers on this topic involving 18 participants were subjected to a grounded theory analysis. Drag genders were tied to common experiences of overcoming social messages that maligned femininity within men, an appreciation of performance arts, and a desire to use social power to confront issues of sexism, genderism, and/or heterosexism. At the same time, participants reported differences in experiencing gender as binary or fluid and in whether they experienced their gender as shifting when engaged in performance. The study contributes to the program of research on LGBTQ genders by examining how drag gender is both essential and constructed, and how it resist sets of oppressive values and is eroticized. It examines how gendered communication functions when performed for audiences and how the social position of these men is both elevated and stigmatized within LGBTQ community. Drag gender’s multiple meanings are credited to its position between gay and transgender politics within this socially transformative moment in time. 相似文献

Living in a disadvantaged neighborhood is associated with heightened risk for poor school readiness and health outcomes in early childhood, and the home environment is thought to be a primary mechanism by which neighborhood context impacts preschoolers. This study examined the effects of neighborhood concentrated disadvantage and neighborhood residential instability on the home physical environment and home learning environment for preschoolers in economically disadvantaged families (N = 187). Using structural equation modeling, mothers' perceived neighborhood disorder and depressive symptoms were examined as mechanisms by which neighborhood context “comes through the door.” Mothers' neighborhood social embeddedness was also explored as a protective factor. Results showed that concentrated disadvantage was negatively associated with the quality of the home physical environment, and residential instability was negatively associated with the quality of the home learning environment. Concentrated disadvantage had an indirect effect on the home learning environment through mothers' perceived neighborhood disorder and depressive symptoms. The effects of concentrated disadvantage on the home environment were buffered by mothers' neighborhood social embeddedness. Study findings advance understanding of socioeconomic‐ and place‐based disparities in developmental outcomes and identify potential targets for interventions aimed at lessening effects of neighborhood disadvantage on families with young children. 相似文献

Postnatal deprivation is associated with neurocognitive delay/dysfunction. Although “catch up” in global cognition following adoption has been reported, this study examined the incidence of specific absolute impairment in adopted children with intact global cognitive functioning. Eighty-five children (38 males, mean age = 112.8, SD = 30.3 months; range 61–209 months) raised from birth in orphanages underwent comprehensive neuropsychological evaluation. Fifty-four were deemed globally intact (IQ > 85). Of those deemed globally intact, 46% evidenced absolute impairment in at least one domain of functioning. Duration of stay in the orphanage was directly associated with incidence of impairment and number of domains affected. A substantial proportion of participants evidenced persistent, absolute impairment in one or more domains of neurocognitive function despite integrity of basic intellectual functions. 相似文献

In the early twentieth century, Hilda Diana Oakeley (1867–1950) set out a new kind of British idealism. Oakeley is an idealist in the sense that she holds mind to actively contribute to the features of experience, but she also accepts that there is a world independent of mind. One of her central contributions to the idealist tradition is her thesis that minds construct our experiences using memory. This paper explores the theses underlying her idealism, and shows how they are intricately connected to the wider debates of her period. I go on to explain how the parts of Oakeley's idealism are connected to further areas of her thought – specifically, her views on history and her growing block theory of time – to provide a sense of Oakeley's philosophy as a system. As there is no existing literature on Oakeley, this paper aims to open a path for further scholarship. 相似文献
