Exploring the interplay between sport modality and cognitive function in open- and closed-skill athletes

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.     

Controlling the flight on double-handed foiling catamarans: The role of shared equipment on the crew members' mutual modes of regulation

The purpose of this study was to contribute to the understanding of the role of shared sport equipment in the collective coordination of a team. It was conducted within an enactive approach of human cognition by mobilizing the methodological tools and methods of the Course of Action framework. Six crew members of hydrofoil sailing catamarans participated in this study. Data collection consisted in video-recording training sessions followed by individual self-confrontation interviews. A qualitative analysis of the data allowed typical modes of regulation of the flight to be characterized from each crew member's perspective. Three main modes of regulation were identified. All of them involved either salient perception of the boat's movements, or actions directed to regulating the boat’s movement. In the discussion, we propose a distinction between three types of collective sport situations, regarding the role of the material environment of athletes in their coordination. This distinction opens new perspectives both for future research on team coordination, and for pedagogical and training implications.     

The importance of reflection and evaluation processes in daily training sessions for progression toward elite level swimming performance

Self-regulated learning (SRL) involves self-directed metacognitive subprocesses and motivational beliefs that facilitate more effective and efficient learning. We investigated whether youth swimmers who are on track to becoming elite swimmers apply SRL subprocesses more frequently in their daily training sessions compared with swimmers who are not on this track. Insights into swimmers’ use of training-centered SRL could advance understanding about underlying individual characteristics that contribute to optimal engagement in daily training and, consequently, progression toward elite level swimming performance. We collected data on training-centered SRL subprocesses (evaluation, planning, reflection, speaking up, effort and self-efficacy) and performance data for 157 youth swimmers aged 12–21 years (73 males and 84 females). The results of a multivariate analysis of covariance revealed significantly higher scores for reflection processes during training for high-performing swimmers but lower scores for effort compared with lower-performing swimmers (p < 0.05). A closer examination of the high-performing group showed that those demonstrating greater improvement during a season scored significantly higher for evaluation processes after training compared with those evidencing less improvement during a season (p < 0.05). Significant between-group differences in SRL subprocesses remained after adjusting for differences in weekly training hours. Youth swimmers on track to becoming elite swimmers are characterized by more frequent use of reflection processes during training and evaluation processes after training, which suggests that these swimmers’ learning and training processes are more effective and efficient. Ultimately, this could contribute to a higher quality of daily training, which may result in greater improvements during a season, higher performance levels, and a greater chance of reaching the level of elite swimming performance.     

先前知识经验对远距离水平映射规则内隐学习的限制

先前研究发现远距离规则能够被内隐地习得和迁移,表明内隐学习获得的知识是底层的抽象规则,那么这一抽象规则的习得和迁移是否会受到先前知识经验的限制?研究采用汉语声调的远距离水平映射规则为材料,通过创设不符合平仄知识经验的任意声调水平映射规则,在控制组块和重复结构等表面特征的条件下,探讨先前知识经验是否限制了远距离水平映射规则的内隐学习和迁移。结果发现相对于符合平仄知识经验的汉语声调水平映射规则,被试不能够内隐地习得和迁移任意声调的水平映射规则,表明先前知识经验在远距离水平映射规则内隐学习过程中发挥着重要作用。     

统计学习与双语认知的关系

统计学习是提取环境输入潜在规则的一种认知机制,其与语言的关联已得到证实。双语认知是学界关注的热点之一。统计学习与双语认知的关系如何?文章先介绍统计学习认知机制及其与语言的关系,然后从“统计学习能力可否预测二语学习表现”、“统计学习训练能否促进二语学习”和“双语经验能否提高统计学习能力”三个维度述评相关文献,并指出未来可从输入特征、个体差异和神经科学角度进一步探讨统计学习与双语认知的关系。     

Dorsolateral prefrontal cortex mediates working memory processes in motor skill learning

Neuroimaging studies have shown that the dorsolateral prefrontal cortex (DLPFC) is recruited during motor skill learning, which suggests the involvement of the DLPFC in working memory (WM) processes, such as selection and integration of motor representations temporarily stored in WM. However, direct evidence linking activation of the DLPFC to WM storage and manipulation during motor skill learning in real-time is rare. In this study, we conducted two experiments to investigate the causal role of DLPFC activity in WM storage and manipulation during motor skill learning under low and high WM-demand conditions. Participants received continuous theta burst stimulation (cTBS) and sham stimulation (crossover design) over the left DLPFC (experiment 1) or right DLPFC (experiment 2). Before and after stimulation, participants in both experiments performed a sequential finger-tapping (SFT) task containing repeated sequence (low-WM demand) and non-repeated sequence (high-WM demand) conditions which are used to study WM processes. The number of correct sequences (NoCS) and reproduction error rate were analyzed. Learning gains in NoCS improved significantly with the practice for both sequence types in the presence of either stimulation type. Compared to sham stimulation, cTBS over the left DLPFC resulted in significantly reduced learning gains in NoCS for non-repeated sequences. These results suggest that the left DLPFC contributes to WM manipulation during motor skill learning.     

来自屏幕的纽带：视频聊天与儿童发展

随着近几年视频聊天的兴起, 越来越多的研究者开始探索视频聊天对儿童发展的影响。相较于传统通讯技术, 视频聊天具备了视听结合与即时互动的特征; 但同时, 作为数字媒体, 视频聊天仍然保持了传统屏幕媒体二维性的特征。汇总以往视频聊天与儿童学习的实证研究发现, 与录制视频教学比较, 视频聊天在婴幼儿词汇学习(d = 0.33)和动作学习(d = 0.90)上的教学效果更佳; 同时, 视频聊天也能够使婴幼儿在教学过程中保持较高的注意水平(d = 0.90)。视频聊天对儿童远距离亲子关系和同伴关系上均有一定的促进作用。视频聊天也可以作为一种辅助治疗手段应用于特殊儿童的干预中。未来研究仍需关注扩大视频聊天学习中儿童被试的年龄范围、共同观看者的不同支持行为对儿童视频聊天学习的效果产生的影响。
