Recent research suggests that infants tend to add words to their vocabulary that are semantically related to other known words, though it is not clear why this pattern emerges. In this paper, we explore whether infants leverage their existing vocabulary and semantic knowledge when interpreting novel label–object mappings in real time. We initially identified categorical domains for which individual 24‐month‐old infants have relatively higher and lower levels of knowledge, irrespective of overall vocabulary size. Next, we taught infants novel words in these higher and lower knowledge domains and then asked if their subsequent real‐time recognition of these items varied as a function of their category knowledge. While our participants successfully acquired the novel label–object mappings in our task, there were important differences in the way infants recognized these words in real time. Namely, infants showed more robust recognition of high (vs. low) domain knowledge words. These findings suggest that dense semantic structure facilitates early word learning and real‐time novel word recognition. 相似文献
This study investigated how various risk and protective factors interface with child health and well-being at the population level. Specifically, we examined the association of income, social-contextual variables, and indicators of health-related habits and activities to children’s life satisfaction and perceived overall health. Child data were collected via a self-report survey, the Middle Years Development Instrument, which was administered in three demographically diverse Canadian school districts to 5026 grade 4 students (83 % of the students had complete data and were included in the analyses). Multiple regression and mediation analyses were conducted to examine the joint associations of social relationships with adults and peers, nutrition and sleep habits, and after school sports activities with children’s satisfaction with life and perceived health. Results indicate that peer belonging and relationships with adults at home and school were the strongest predictors of life satisfaction. Furthermore, the (small) association between income and life satisfaction was mediated by social relationship variables. Child reports of perceived health were predicted by peer belonging, adult relationships (home, school, neighborhood), after-school team sports, and nutrition habits. The (small) association between income and health was mediated by social relationships and team sports participation. Findings are discussed in light of previous research on social determinants and socio-economic gradients of children’s health and life satisfaction. 相似文献
Social and geographic displacement is a global phenomenon that precipitates novel stressors and disruptions that intersect with long-standing familial and social roles. Among the displaced are war-torn Iraqi refugee families, who must address these new obstacles in unconventional ways. This study explores how such disruptions have influenced associations between gender and apparent self-worth experienced by Iraqi refugee families upon relocation to the USA. Further, the psychosocial mechanisms requisite of any novel approach to a new social construct are explored and reveal that production in the family is at the core of instability and shifting power dynamics during resettlement, preventing family members from “seeing the life” in the USA that they had envisioned prior to immigration. Over 200 semi-structured qualitative interviews with Iraqi participants and mental health providers were conducted over the course of the study, which demonstrate a plasticity among social roles in the family and community that transcends the notion of a simple role reversal, and illustrate the complex positionalities that families under stress must approximate during such physical and social displacement. 相似文献
Objective. A randomised controlled trial (RCT) was conducted to evaluate a three-hour face-to-face physical activity (PA) intervention in community-dwelling older German adults with four groups: The intervention group (IG) received behaviour change techniques (BCTs) based on the health action process approach plus a views-on-ageing component to increase PA. The second intervention group ‘planning’ (IGpl) contained the same BCTs, only substituted the views-on-ageing component against an additional planning task. An active control group received the same BCTs, however, targeting volunteering instead of PA. A passive control group (PCG) received no intervention.
Design. The RCT comprised 5 time-points over 14 months in N = 310 participants aged 64+.
Main outcome measures. Self-reported as well as accelerometer-assessed PA.
Results. Neither PA measure increased in the IG as compared to the other groups at any point in time. Bayes analyses supported these null-effects.
Conclusion. A possible explanation for this null-finding in line with a recent meta-analysis is that some self-regulatory BCTs may be ineffective or even negatively associated with PA in interventions for older adults as they are assumed to be less acceptable for older adults. This interpretation was supported by observed reluctance to participate in self-regulatory BCTs in the current study. 相似文献
In this article, I consider the harms inflicted upon transgender persons through “misgendering,” that is, such deployments of gender terms that diminish transgender persons' self‐respect, limit the discursive resources at their disposal to define their own gender, and cause them microaggressive psychological harms. Such deployments are morally contestable, that is, they can be challenged on ethical or political grounds. Two characterizations of “woman” proposed in the feminist literature are critiqued from this perspective. When we consider what would happen to transgender women upon the broad implementation of these characterizations within transgender women's social context, we discover that they suffer from two defects: they either exclude at least some transgender women, or else they implicitly foster hierarchies among women, marginalizing transgender women in particular. In conclusion, I claim that the moral contestability of gender‐term deployments acts as a stimulus to regularly consider the provisionality and revisability of our deployments of the term “woman.” 相似文献
