There is a growing body of research on the modifiability of executive functions in different stages of life. Previous studies demonstrate robust training effects but limited transfer in younger and particularly in older adults. The aim of the present study was to investigate whether a theoretically derived intervention for executive functioning, addressing several basic processes (updating, shifting, and inhibition), can induce transfer effects in early and late adulthood. Fifty-nine healthy adults, 29 young and 30 older adults, were randomly assigned to either training or no-contact control groups. The training groups received 15 sessions of executive process training for about 45 min/session during 5 weeks. A test battery including a criterion task and near, intermediate, and far transfer tasks was administered before and after training. Results showed pronounced age-equivalent gains on the criterion task. Near transfer was seen to non-trained updating and inhibition tasks for the young and older trained participants. However, only the young adults showed intermediate transfer to two complex working memory tasks. No far transfer effects were seen for either age group. These findings provide additional evidence for age-related constraints in the ability to generalize acquired executive skills, and specifically show that training of multiple executive processes is not sufficient to foster transfer beyond the very near in older adults. 相似文献

本研究以300个三至六年级双亲家庭中的儿童和母亲为研究对象,采用儿童版和家长版教养方式问卷、父母与同伴依恋问卷、流调中心抑郁量表,通过响应面分析法探讨了母子感知到的教养方式差异与儿童抑郁的关系,并使用标准分差法计算感知差异,通过结构方程模型分析了母子依恋是否在其中起到中介作用。研究发现:(1)母亲感知到的权威型、独裁型教养方式显著高于儿童感知,而纵容型教养方式则显著低于儿童;(2)权威型教养方式的母子感知差异正向线性预测儿童抑郁,独裁型教养方式的母子感知差异负向线性预测儿童抑郁,纵容型教养方式的感知差异对儿童抑郁没有显著预测作用;(3)母子依恋质量在权威型教养方式的母子感知差异和儿童抑郁之间起完全中介作用,但在独裁型教养方式的母子感知差异对儿童抑郁的预测中没有起到中介作用。 相似文献

To provide a better understanding of individual driver’s driving style classification in a traditional and a CV environment, spatiotemporal characteristics of vehicle trajectories on a road tunnel were extracted through a driving simulator-based experiment. Speed, acceleration, and rate of acceleration changes are selected as clustering indexes. The dynamic time warping and k-means clustering were adopted to classify participants into different risk level groups. To assess the driver behavior benefits in a CV environment, an indicator BI (behavior indicator, BI) was defined based on the standard deviation of speed, the standard deviation of acceleration, and the standard deviation of the rate of acceleration change. Then, the index BI of each driver was calculated. Furthermore, this paper explored driving style classification, not in terms of traditional driving environment, but rather the transition patterns from a traditional driving environment to a CV environment. The results revealed that inside a long tunnel, 80 % of drivers benefited from a CV environment. Moreover, drivers might need training before using a CV system, especially female drivers who have low driving mileage. In addition, the results showed that the driving style of 69 % of the drivers’ transferred from a high risk-level to a low risk-level when driving in a CV environment. The study results can be expected to improve driving training education programs and also to provide a valuable reference for developing individual in-vehicle human-machine interface projects and other proactive safety countermeasures. 相似文献

The degree to which each sport modality relies on cognitive visual skills is hitherto under-researched. This study sought to further understanding of the relationship between sport modality and visual search ability, visual working memory, and reasoning. Ninety-five participants took part in the present study. In order to assess visual search ability, we employed the Visual Search Task. Visual working memory was assessed through the Corsi Block Tapping – Backwards Task. Reasoning abilities were assessed through the Cognitive Reflection Task. Results indicate that visual search skills appear to benefit to a higher extent from open-skill sports when compared to closed-skill sports. It is important to emphasize, however, that this result was associated with a small effect size. Moreover, the present findings indicate that closed-skill athletes do not differ in terms of visual search abilities, working memory, and reasoning abilities when compared to control individuals. 相似文献

Effects of motivation on cognition and performance have been found empirically in different fields. However, the relationship between motivation and performance seems complex and multi-faceted. While seemingly inconsistent or incompatible studies and theories of different disciplinary origins exist in this regard, we show that many of them can potentially be synthesized. Simulations within a unifying computational cognitive architecture account for empirical phenomena from different studies, which demonstrate that a mechanistic (computational) account can potentially unify the interpretations of these studies, largely based on utility calculation from intrinsic motives, and allow for further, more detailed explorations. 相似文献

In this paper we present a computational modeling account of an active self in artificial agents. In particular we focus on how an agent can be equipped with a sense of control and how it arises in autonomous situated action and, in turn, influences action control. We argue that this requires laying out an embodied cognitive model that combines bottom-up processes (sensorimotor learning and fine-grained adaptation of control) with top-down processes (cognitive processes for strategy selection and decision-making). We present such a conceptual computational architecture based on principles of predictive processing and free energy minimization. Using this general model, we describe how a sense of control can form across the levels of a control hierarchy and how this can support action control in an unpredictable environment. We present an implementation of this model as well as first evaluations in a simulated task scenario, in which an autonomous agent has to cope with un-/predictable situations and experiences corresponding sense of control. We explore different model parameter settings that lead to different ways of combining low-level and high-level action control. The results show the importance of appropriately weighting information in situations where the need for low/high-level action control varies and they demonstrate how the sense of control can facilitate this. 相似文献

The third wave of the National Congregations Study (NCS‐III) was conducted in 2012. The 2012 General Social Survey asked respondents who attend religious services to name their religious congregation, producing a nationally representative cross‐section of congregations from across the religious spectrum. Data about these congregations were collected via a 50‐minute interview with one key informant from 1,331 congregations. Information was gathered about multiple aspects of congregations’ social composition, structure, activities, and programming. Approximately two‐thirds of the NCS‐III questionnaire replicates items from 1998 or 2006–2007 NCS waves. Each congregation was geocoded, and selected data from the 2010 U.S. Census or American Community Survey have been appended. We describe NCS‐III methodology and use the cumulative NCS dataset (containing 4,071 cases) to describe five trends: more ethnic diversity, greater acceptance of gays and lesbians, increasingly informal worship styles, declining size (but not from the perspective of the average attendee), and declining denominational affiliation. 相似文献

It is helpful to teach students of religion and theology that it's not just the teachings and practices of a religion that are important, but the way in which these beliefs and practices are handled that's critical, whether in a liberal or a conservative way. Recent work in Cognitive Linguistics has helped pastors and religion teachers introduce this other dimension of their subject in new ways. 相似文献
