Electrocortical and behavioral responses of low, moderate, and high physically active older adults were compared with a younger control group on neutral and incompatible conditions of a flankers task. Compared to younger adults, high and moderate active older adults exhibited increased event-related potentials component P3 amplitude for the incompatible condition at the frontal electrode site. For the neutral condition, only low active older adults exhibited decreased amplitude at the central-parietal site, compared to younger adults. P3 latency revealed the longest latencies for low active older adults, followed by moderate active, high active, and younger adults, respectively. Reaction time (RT) data revealed that younger adults exhibited faster RT compared to all three older groups. Results suggest that physical activity may improve executive control function in older adults by affecting the distribution of P3 amplitude, which has been related to memory and attentional processes, and by decreasing P3 latency, which relates to the speed of cognitive processing.  相似文献

The purpose of this study was to examine evidence for the validity of a stages of change measure of the Transtheoretical Model for exercise behavior. Participants were 152 university students (53.3% women, 71.6% Caucasian, M age = 19.18 years) who completed processes of change, self-efficacy, decisional balance, stages of change, and exercise behavior questionnaires as well as a maximal treadmill test. Participants in the action and maintenance stages had the highest strenuous (PC/C/P < A/M) and moderate (PC/C < A/M) self-reported exercise behavior. Those in the maintenance stage had the highest estimated aerobic fitness (PC/P < MA). The differences between the early stages (PC, C, and P) and the later stages (A and M) as described by the first function were primarily due to the behavioral process of change. The differences between the extreme stages (PC and M) and the middle stages (C, P, and A) were due to the experiential processes of change and the pros of decisional balance. The hypothesized patterns of stage differences were partially supported. Failure to obtain full support may have been due to methodological issues or inherent difficulties in detecting evidence for the validity of stages of change measures.  相似文献

Administrators need intense support in their early years in their jobs to master the demands of the position and to emerge as effective leaders for their schools. This article reports on a leadership coaching program offered by a university to support graduates as they transition to new school leadership roles. First year research results of the Program for New Principals indicate that all of the program participants felt that the coaching program was a positive addition to the induction experience for new administrators. New principals viewed coaching positively and emphasized that it is both a valuable and unique form of professional development. Both coaches and new principals cited personalized support as one of the coaching model's most significant assets. The results should inform the development of a model of leadership coaching for new administrators.  相似文献

A growing body of research documents the positive outcomes of research experiences for undergraduates, including increased persistence in science. Study of undergraduate lab learning experiences has demonstrated that the design of the experience influences the extent to which students report ownership of the project and that project ownership is one of the psychosocial factors involved in student retention in the sciences. To date, methods for measuring project ownership have not been suitable for the collection of larger data sets. The current study aims to rectify this by developing, presenting, and evaluating a new instrument for measuring project ownership. Eighteen scaled items were generated based on prior research and theory related to project ownership and combined with 30 items shown to measure respondents’ emotions about an experience, resulting in the Project Ownership survey (POS). The POS was analyzed to determine its dimensionality, reliability, and validity. The POS had a coefficient alpha of 0.92 and thus has high internal consistency. Known-groups validity was analyzed through the ability of the instrument to differentiate between students who studied in traditional versus research-based laboratory courses. The POS scales as differentiated between the groups and findings paralleled previous results in relation to the characteristics of project ownership.  相似文献

Previous research has suggested that fluency does not influence memory decisions until ages 7–8. In two experiments (n = 96 and = 64, respectively), children, aged 4, 6, and 8 years (Experiments 1 and 2), and adults (Experiment 2) studied a list of pictures. Participants completed a recognition test during which each study item was preceded by a sound providing either a highly predictive or mildly predictive context in order to make some test items more conceptually fluent. Overall, highly predictive items were recognized at a higher rate than mildly predictive items demonstrating an earlier development of the fluency heuristic than previously observed. The study provides insight into how children develop metacognitive expectations and when they start to use them to guide their memory responses.  相似文献

This article explores the findings of a small research study that asked writers to describe a meaningful, personal incident using first narrative and then poetic forms. The poetry raised many anxieties about writing, including the revelations of subjectivity and the risks in sharing such work with a group. To understand some of the complexities of these responses, the researchers thought of writing as an ecology with interdependent systems influencing the writing. Rereading the research texts, they traced some of those systems that affect students' writing and understanding of poetry.  相似文献

Preschool children's social interactions with teachers and peers were observed in the context of moral and prudential events. Twenty groups of children were observed during free play for a total of 164 hours (8 hours per each group). Four types of moral transgressions were observed: physical harm, psychological harm, property loss, and property damage. The majority of the moral transgressions pertained to physical harm and property loss. There were equal frequencies of both moral and prudential physical harm acts; Moral physical harm acts resulted in actual harm; whereas, prudential acts were only potentially harmful. Teachers responded differently to moral and prudential rule violations. Gender differences were noted with regard to instigator, victim teachers' responses, and victims' responses.  相似文献

Privacy has been defined as “the protective buffer within which people can avoid another party’s taking something from them, keeping watch over them, or entering into their lives in a way that is both unwelcome and undesirable”. It is a premise of this paper that such a position needs to be taken very seriously in contemporary society, and particularly in the case of schools, as school personnel have the capacity to engage in practices which show great disregard for individual and family privacy. This is illustrated in the case of primary school education in the Republic of Ireland. Particular attention is paid to assessment, pedagogical and curricular practices that derive from patterns of systematic and mandatory disclosure that are confessional, performative and public.  相似文献
