Children's understanding of the quantities represented by number words (i.e., cardinality) is a surprisingly protracted but foundational step in their learning of formal mathematics. The development of cardinal knowledge is related to one or two core, inherent systems – the approximate number system (ANS) and the object tracking system (OTS) – but whether these systems act alone, in concert, or antagonistically is debated. Longitudinal assessments of 198 preschool children on OTS, ANS, and cardinality tasks enabled testing of two single‐mechanism (ANS‐only and OTS‐only) and two dual‐mechanism models, controlling for intelligence, executive functions, preliteracy skills, and demographic factors. Measures of both OTS and ANS predicted cardinal knowledge in concert early in the school year, inconsistent with single‐mechanism models. The ANS but not the OTS predicted cardinal knowledge later in the school year as well the acquisition of the cardinal principle, a critical shift in cardinal understanding. The results support a Merge model, whereby both systems initially contribute to children's early mapping of number words to cardinal value, but the role of the OTS diminishes over time while that of the ANS continues to support cardinal knowledge as children come to understand the counting principles. 相似文献
Objective: Exercise behaviour change involves multiple experiences with success and failure. The Model of Action Phases (MAP) offers a dynamic account of how success and failure influence both immediate evaluations and future decisions and actions. However, predictions from the MAP have not been formally tested.
Design: A longitudinal daily diary study was used to examine how post-behaviour evaluations of exercise success and failure influence subsequent exercise intentions and behaviour. Participants (N = 104) set exercise goals, and then kept a daily online exercise diary for four weeks.
Main outcome measures: Participants self-reported exercise behaviour, affective response to exercise, self-evaluations after success or failure at following through on intentions to exercise, and intentions to exercise in the next week.
Results: Multilevel modelling revealed significant within- and between-participant relationships among post-behaviour evaluations, intentions and subsequent behaviour. Findings supported MAP-derived predictions about how success and failure at exercise are associated with feelings about exercise and the self, and inform subsequent exercise intentions and behaviour.
Conclusion: Positive post-behaviour evaluations of success or failure may stabilise positive intentions and aid maintenance of exercise behaviour. Implications of these MAP-based findings for intervention design are discussed. 相似文献
ABSTRACTThe population of Muslims living in the Republic of Ireland has increased significantly in recent years. Despite Muslims being one of the fastest growing minorities in the country, there is a paucity of research on the educational choices of Muslim parents. This study draws on ethnographic fieldwork conducted between 2013 and 2014. Based on semi-structured interviews, this article focuses on the views of Muslim parents and teachers from two Muslim state-funded primary schools in Ireland. The interviews revealed that, for most parents, the schools’ Islamic ethos was an underlying motivation for enrolling their children at Muslim schools. The findings also demonstrate the negative reasons of their choices, such as the lack of accommodation and the feelings of isolation they and their children experienced in non-Muslim schools, which further heightens the perception that Muslim schools in Ireland act as safe environments that protect the cultural and religious identities of Muslim children. The article concludes with some considerations for future research. 相似文献
The present study explored self-perceptions and meta-stereotypes along two dimensions, individuation and sociability, within a sample of Asian American and European American students. For both ethnic groups, meta-stereotypes in dimensions of individuation and sociability appear to be exaggerated forms of self-perceptions along these dimensions. Both Asian and European Americans distinguish between self-perceptions of sociability and individuation, showing that sociability and individuation are two independent constructs. Asian Americans, however, perceived that others who expect a certain level of sociability from their ethnic group would also expect the same level of individuation. Implications of these findings for the perpetuation of Asian stereotypes are discussed. 相似文献
Researchers and practitioners have long regarded procrastination as a self-handicapping and dysfunctional behavior. In the present study, the authors proposed that not all procrastination behaviors either are harmful or lead to negative consequences. Specifically, the authors differentiated two types of procrastinators: passive procrastinators versus active procrastinators. Passive procrastinators are procrastinators in the traditional sense. They are paralyzed by their indecision to act and fail to complete tasks on time. In contrast, active procrastinators are a "positive" type of procrastinator. They prefer to work under pressure, and they make deliberate decisions to procrastinate. The present results showed that although active procrastinators procrastinate to the same degree as passive procrastinators, they are more similar to nonprocrastinators than to passive procrastinators in terms of purposive use of time, control of time, self-efficacy belief, coping styles, and outcomes including academic performance. The present findings offer a more sophisticated understanding of procrastination behavior and indicate a need to reevaluate its implications for outcomes of individuals. 相似文献
Based on a model on spumed helpers’ reactions, a spurning scale for nurses was constructed with items to assess the extent
to which practicing nurses experience recurrent rejection of their help by patients and colleagues. Three approaches were
employed to examine the validity of the scale: the relationship of the spurning scores with job satisfaction and turnover
scores; the relationships of the spurning scores with burnout scores; and the relationships of the spurning scores with scores
indicative of stress arising from interactions with one's patients, colleagues, and supervisor. Practicing nurses in Hong
Kong (N = 212) who were enrolled in a refresher program of studies responded to a questionnaire containing the variables of
interest. The results offered promising evidence for the validity of the scale. 相似文献
