Everyday function is compromised by mild cognitive changes in aging. These changes predict risk for future decline and dementia but remain poorly characterized, largely due to a scarcity of sensitive, objective measures.Twenty-seven younger adults and 25 non-demented older adults completed the Naturalistic Action Test (NAT), a performance-based measure of everyday action involving simple and complex tasks. Performance was coded for overt errors and subtle inefficiencies. Participants also completed self-report functional measures and cognitive tests. Mixed ANOVAs revealed that older adults made more subtle NAT errors with high task demands; groups did not differ in overt errors. Correlations did not reveal significant relations between self-report and NAT errors, but NAT performance was correlated with learning and recall.The NAT provides a promising tool for detecting subtle age-related changes and examining decline across levels of impairment. Self-report may lack sensitivity to subtle changes, and episodic memory changes underlie early functional disruption. 相似文献

Literature has shown that the use of reflective practice is one way to assist students to understand and adjust to the expectations demanded by higher education. However, the implementation of reflective practice within the classroom can be challenging especially more so for the science, technology, engineering and mathematics discipline. It is often the case that reflective exercises are incorporated into the classrooms without further thought beyond the assignment of a reflective journal and students are asked to reflect without being taught how. This paper reviews existing models of reflection and discusses its application to the field of computing education particularly in the design of class activities to train students to reflect. Existing literature on how reflective activities are incorporated into assessments and classroom activities for different purposes are also reviewed to determine factors that contribute to its successful implementation in the classroom. 相似文献

We examined how psychic distance moderates the association of South Korean chief executive officers’ (CEOs’) knowledge and quality management with their predisposition to invest in African technology and innovation markets. Participants were current and prospective South Korean African business investment senior managers (n = 64; 20 females; mean years in management = 19.4) or not (n = 187; 97 females, mean years in management = 15.9). Hierarchical regression analysis was used to analyse the relationships. Only quality management was significantly related to technology commercialisation capabilities and innovation performance among managers with African investment experience. However, both quality and knowledge management were significantly related to the outcomes among managers without African investment experience. The effect of psychic distance might be explained by risk averseness, in that those without experience of African investment might be with more risk avoidant than those with such experience. 相似文献

Research shows that R&D's use of sales’ market intelligence positively influences innovation performance. However, little is known about whether this effect hinges on salespersons’ engagement towards and perceptions of market intelligence activities (MIA). Moreover, research remains incomplete regarding the drivers of salespersons’ MIA engagement. Using dyadic data from 359 salespersons and 239 R&D managers in a multi-level model based on the job demands-resources theory, we demonstrate that the positive effect of R&D's use of sales’ market intelligence on innovation performance is especially pronounced when salespersons’ market intelligence generation is high and role ambiguity is low. We also show that although salespersons’ self-set MIA goals are a strong driver of their MIA engagement, not assigning salespersons MIA goals may be a double-edged sword: in the short run, salespersons might engage in MIA voluntarily. However, in the long run, they could incur psychological costs in terms of role ambiguity and conflict, preventing them from engaging in MIA. 相似文献

ObjectivesContextual factors can influence the way sports officials apply unambiguous rules. The aim of this study was to better understand the leg-before-wicket (LBW) decision-making behaviour of elite cricket umpires and determine whether their behaviour changes according to the format of the game in which they are adjudicating.MethodsLBW decisions (n = 5578) from actual elite level cricket matches in Australia between 2009 and 2016 were analysed using a signal detection paradigm. Umpire sensitivity (A) and response bias (B) were compared to chance performance in three formats of the game: Four-day, One-day, and T20. Mixed effects models assessed sensitivity and response bias differences between match types.ResultsUmpires were able to differentiate between “out” and “not out” appeals to a high standard but were conservative and had a bias to respond “not out” in all formats of the game. Umpires were less accurate in the shorter formats of the game, particularly T20 cricket and were also significantly more conservative in T20 compared to Four-day Matches.ConclusionsCricket umpires are conservative and are highly accurate LBW decision makers. However, differences in their judgments were associated with different match formats. The unique task goals and contextual pressures afforded by the shorter formats of the game, particularly T20, may account for the observed performance differences we see here. 相似文献

The purpose of this research was to measure the frequency and variety of number activities occurring in the homes of pre-school and kindergarten children and to determine if there was a relationship between those activities and the children's mathematical performance. In two studies, parents were interviewed over the telephone and asked how often their child or they and their child had engaged in each of 33 number-related activities over the last week. Both studies found considerable variability in the frequency and type of number activities that children participated in at home. There was a positive correlation between the frequency of number activities that parents reported for their children and parental participation in the same activities. In addition, in study 2, parental reports of children's number activities at home were predictive of children's performance on a standardized test of early mathematical ability. 相似文献

Transplant candidates completed the Every Day Problems test (EPT), a performance-based measure of instrumental activities of daily living (IADL), and the Katz self-report scale of IADL functioning. Caregivers estimated the candidate's IADL capacity using the Katz scale. A healthy community group and patients with cardiac disease not undergoing transplant evaluation and their caregivers served as controls. Discrepancies between the EPT and Katz scales were generated. Results showed that the total number of discrepancies was significantly higher among the two patient groups as compared to controls. Three or more discrepancies (a total of 7 IADL domains were assessed) occurred in 40–52% of the participants and their caregivers in the two patient groups. Similarly, the total number of discrepancies between the Katz scale of the participant and their caregiver was significantly higher among the two patient groups as compared to controls, with only 33–44% showing perfect agreement in the patient groups as compared to 97% among controls. Despite a high prevalence of discrepancies in both patient groups, results did not support the hypothesis that transplant candidates tend systematically to overestimate their ability level on self-report IADL measures. 相似文献
