Does movement proficiency impact on exergaming performance?

There is growing interest in the use of consumer level exergames in movement skill acquisition. The purpose of this study was to investigate the relationship between movement proficiency and performance in virtual exergaming. Twenty seven children, aged 10–15 years participated in an experiment completing the Movement Assessment Battery for Children 2 (MABC-2) and a series of XBOX360 Kinect Sports exergaming tasks. Significant correlations were observed between MABC-2 aiming and catching percentile and exergame javelin and target kick, where the more proficient movers tended to perform better in the exergame. Statistically significant correlations were observed between MABC-2 balance percentile and exergaming sprint and target kick performance. In this study children who scored better in real life gross motor movement tasks performed better in most related exergaming activities. This suggests current exergaming technology has advanced to a point where body movement unencumbered by a physical or remote game device tether can extract movements resembling real life tasks, translate them into game play and reward proficient movers with higher in-game performance. It is possible that benefit gained in an exergaming environment by more proficient movers was a result of either their more proficient movement, or a greater ability to adapt to the exergame.     

The effect of instruction to synchronize over step frequency while walking with auditory cues on a treadmill

Walking to a pacing stimulus has proven useful in motor rehabilitation, and it has been suggested that spontaneous synchronization could be preferable to intentional synchronization. But it is still unclear if the paced walking effect can occur spontaneously, or if intentionality plays a role. The aim of this work is to analyze the effect of sound pacing on gait with and without instruction to synchronize, and with different rhythmic auditory cues, while walking on a treadmill.Firstly, the baseline step frequency while walking on a treadmill was determined for all participants, followed by experimental sessions with both music and footstep sound cues. Participants were split into two groups, with one being instructed to synchronize their gait to the auditory stimuli, and the other being simply told to walk. Individual auditory cues were generated for each participant: for each trial, cues were provided at the participant’s baseline walking frequency, at 5% and 10% above baseline, and at 5% and 10% below baseline.This study’s major finding was the role of intention on synchronization, given that only the instructed group synchronized their gait with the auditory cues. No differences were found between the effects of step or music stimuli on step frequency.In conclusion, without intention or cues that direct the individual’s attention, spontaneous gait synchronization does not occur during treadmill walking.     

Personalization in Mother–Child Emotion Talk Across Three Contexts

An unexplored aspect of contextual variation in emotion talk is the extent to which the emotions mothers and children discuss relate to the child, mother, or another self. To establish the extent to which mothers and children personalize the emotions they discuss, we examined the emotion talk of 40 American mother–child dyads in three conversational contexts: reminiscing, book reading, and play. We found that both mothers and children talked about emotions directly relevant to the child mostly in the reminiscing context and about emotions relating to another self mostly in the book context. Interestingly, the discussion of personalized emotions did not significantly differ between the book and play contexts, but did for the independent emotions. The discussion of mothers' own emotions occurred with almost the same frequency in all three contexts. In addition, within‐context analyses revealed that while mothers discussed the child's and their own emotions in the book and play contexts at about the same rate, children focused on their own emotions significantly more than on mothers' emotions in all three contexts. We contextualize the significance of the results in light of intervention programmes and future research. Copyright © 2013 John Wiley & Sons, Ltd.     

汉字笔画像素数省略对中文句子阅读影响的眼动研究

在前人笔画省略实验的基础上,采用“像素省略”这一更精确的变量操纵来探讨笔画省略对汉字识别的影响。实验采用2（像素省略方式：省前、略后）×3（像素省略水平：15%、30%、50%）被试内设计,分析整句阅读的眼动轨迹。结果显示,像素省略水平越高对阅读的干扰越大,省前条件下对阅读的干扰显著大于略后条件。结果进一步证实了汉字书写顺序对汉字识别的影响,先书写的笔画比后书写的笔画对汉字的识别起到更大的作用,即笔画顺序效应。     

Why theatre-based research works? Psychological theories from behind the curtain

While many scholars have demonstrated the effectiveness of theatre-based knowledge mobilization, fewer studies have examined its psychological dimensions. This article examines some psychological theories that may account for the success behind theatre-based knowledge mobilization. Drawing from the Canadian Experience Project, a study about the labor market challenges of skilled immigrant workers, we show how theatre-based research dissemination efforts attempt to achieve optimal stress by using aesthetic distance processes. We maintain that this psychological capacity to attune to audience members, especially evident in forum theatre, makes theatre a particularly effective means for knowledge mobilization.     

Investigating How Test-Takers Change Their Strategies to Handle Difficulty in Taking a Reading Comprehension Test: Implications for Score Validation

This article investigates how test-takers change their strategies to handle increased test difficulty. An adult sample reported their test-taking strategies immediately after completing the tasks in a reading test. Data were analyzed using structural equation modeling specifying a measurement-invariant, ability-moderated, latent transition analysis in Mplus (Muthén & Asparouhov, 2011). It was found that almost half of the test-takers (47%) changed their strategies when encountering increased task-difficulty. The changes were characterized by augmenting comprehending-meaning strategies with score-maximizing and test-wiseness strategies. Moreover, test-takers' ability was the driving influence that facilitated and/or buffered the changes. The test outcomes, when reviewed in light of adjusted test-taking strategies, demonstrated a form of process-based validity evidence.

小学一年级阅读流畅性对二、三年级阅读理解的预测

采用追踪研究考察了124名小学一年级儿童的阅读流畅性对其二、三年级阅读理解的影响。结果发现,在控制了性别、家庭社会经济地位、推理能力、汉字识别、口语词汇及多种阅读相关认知技能之后,儿童一年级时的字词流畅性可以预期其二、三年级时的阅读理解水平,句子流畅性对二年级时阅读理解的变异有独特解释作用,但对三年级时阅读理解的变异没有显著的解释作用。相对于句子流畅性,字词流畅性在小学低年级阶段对阅读理解的贡献更大。     

Recurrence of phonetic responding

This study determined if previously reinforced academic responding recurred when alternative responses were differentially reinforced and subsequently placed on extinction, and whether the magnitude of resurgence was related to the rate of differential reinforcement for the alternative behavior. Three kindergarten students read Greek letters aloud as arbitrary consonant–vowel blends. Resurgence was reliably demonstrated within and across participants, and the magnitude of resurgence was related to the prior rate of differential reinforcement of alternative behavior.
