She writes in many-coloured headscarves! A conversation with Shelina Zahra Janmohamed

Shelina Janmohamed, the British Muslim writer and commentator, feels impatient with the stereotypic labels attributed by the West to Asian Muslim women. Through her memoir, Love in a Headscarf, she breaks out all the miserable images of what it is to be a British Asian Muslim woman, addressing issues that range from Asian marriages to Islamic terrorism and the question of the veil.     

Anthropocentric Rhetorical Discourse in Popular Science Writing about Human Evolution

Discourse describing evolution in contemporary popular science writing often posits that humans evolved not from an ape, but from a merely ape-like or generalized primate. Contemporary fossil and genetic evidence, though, have revealed what can accurately be described as an extinct ape species as ancestral to the human lineage. The persistence of ambiguous terms in popular science writing may be interpreted as a form of anthropocentric rhetorical discourse. Nonetheless, while such discourse is often justified in terms of increasing the public understanding of science, it may also mitigate (whether consciously intended or not) religion-based resistance to evolutionary theory.     

Using Community Partnerships to Better Understand the Barriers to Using an Evidence‐Based,Parent‐Mediated Intervention for Autism Spectrum Disorder in a Medicaid System

Service use disparities have been noted to impede under‐resourced families' ability to access high‐quality services for their child with autism spectrum disorder (ASD). These disparities are particularly relevant for parent‐mediated interventions and may suggest a lack of fit between these interventions and the needs of under‐resourced community settings. This study used Roger's Diffusion of Innovations theory to guide community partnerships aimed at understanding the perceived compatibility, complexity, and relative advantage of using an evidence‐based, parent‐mediated intervention (Project ImPACT) within a Medicaid system. Three focus groups were conducted with 16 Medicaid‐eligible parents, and three focus groups were conducted with 16 ASD providers operating within a Medicaid system. Across all groups, parents and providers reported general interest in using Project ImPACT. However, primary themes emerged regarding the need to (a) reduce the complexity of written materials; (b) allow for a more flexible program delivery; (c) ensure a strong parent–therapist alliance; (d) involve the extended family; and (e) help families practice the intervention within their preexisting routines. Results are discussed as they relate to the design and fit of evidence‐based, parent‐mediated interventions for under‐resourced community settings.     

Intra- and inter-subject variation in lower limb coordination during countermovement jumps in children and adults

The purpose of the present study was to investigate the coordination pattern and coordination variability (intra-subject and inter-subject) in children and adults during vertical countermovement jumps. Ten children (mean age: 11.5 ± 1.8 years) and ten adults (mean age: 26.1 ± 4.9 years) participated in the experiment. Lower body 3D-kinematics and kinetics from both legs were obtained during 9 vertical jumps of each subject. Coordination pattern and coordination variability of intra-limb and inter-limb coupling were established by modified vector coding and continuous relative phase. The adult group jumped higher and with less performance variability compared to the children. Group differences were mainly observed in the right–left foot coupling. The intra-subject coordination variability was higher in coupling of proximal segments in children compared to adults. No group differences were observed in inter-subject variability. Based on these results, it was concluded that the same movement solutions were available to both age groups, but the children were less able to consistently utilize the individually chosen coordination pattern. Thus, this ability appears to be developed through normal ontogenesis.     

Visual perceptual and handwriting skills in children with Developmental Coordination Disorder

ObjectiveChildren with Developmental Coordination Disorder demonstrate a lack of automaticity in handwriting as measured by pauses during writing. Deficits in visual perception have been proposed in the literature as underlying mechanisms of handwriting difficulties in children with DCD. The aim of this study was to examine whether correlations exist between measures of visual perception and visual motor integration with measures of the handwriting product and process in children with DCD.MethodThe performance of twenty-eight 8–14 year-old children who met the DSM-5 criteria for DCD was compared with 28 typically developing (TD) age and gender-matched controls. The children completed the Developmental Test of Visual Motor Integration (VMI) and the Test of Visual Perceptual Skills (TVPS). Group comparisons were made, correlations were conducted between the visual perceptual measures and handwriting measures and the sensitivity and specificity examined.ResultsThe DCD group performed below the TD group on the VMI and TVPS. There were no significant correlations between the VMI or TVPS and any of the handwriting measures in the DCD group. In addition, both tests demonstrated low sensitivity.ConclusionClinicians should execute caution in using visual perceptual measures to inform them about handwriting skill in children with DCD.     

道不同不相为谋? 信息相关断裂带对团队学习的影响

传统观点认为,存在断裂带的团队中成员学习行为会受到不利影响,即"道不同不相为谋"。本研究通过聚焦信息相关断裂带,全面剖析内部学习和外部学习等不同团队学习方式,深入考察影响断裂带团队学习的关键情境因素,探讨并论证本文的基本观点——"道不同",可以"相为谋"。基于56个实际工作团队配对样本数据的统计分析结果表明,信息相关断裂带对团队内部学习和外部学习都没有直接作用。团队共同任期和交互记忆系统对信息相关断裂带团队内外部学习起调节作用:团队共同任期越长,信息相关断裂带越有利于团队内部学习及外部学习;交互记忆系统水平越高,信息相关断裂带越有利于团队内部学习及外部学习。     

低阶层者的系统合理化水平更高吗?——基于社会认知视角的考察

系统合理化理论曾提出,低阶层者比高阶层者具有更高的系统合理化水平,即更认可社会体系的合理性、更支持当前社会系统。但这一论断一直存在争议。研究引入社会认知视角,考察低阶层与高阶层者系统合理化水平的差异及其机制。两个分研究得到了共同的结果:(1)低阶层者的系统合理化水平显著低于高阶层者;(2)这一差异是通过贫富归因的中介作用实现的,低阶层者系统合理化水平较低是基于其更少地认为社会贫富差距是由个人内部因素所致;(3)这一中介作用会受到个体控制感水平的调节,当控制感较低时,上述中介作用成立;但当控制感较高时,低阶层会弥合与高阶层贫富归因的差异,中介模型不成立。这些结果支持并发展了系统合理化的认知途径解释和阶层社会认知理论这两个立足于社会认知的理论观点,显示了认知因素在此问题中的重要作用,构建了更整合的阶层—归因—合理化的逻辑,并考虑了其边界因素,对于了解低阶层者的社会心态及其形成机制,包括如何改变此状况,均有一定的现实启示意义。     

儿童汉字练习:纸笔手写与键盘拼音输入的效果比较

在学校情境下,采用纸笔手写和键盘拼音输入练习汉字的实验任务,比较了75名小学六年级儿童在两种练习方式下的汉字学习及复习效果,并进行了保持效果的追踪。结果发现,纸笔手写和键盘拼音输入对儿童的汉字复习具有同等积极作用,在再认选择和回忆书写上效果均相当;对儿童的汉字学习积极作用不一致:在再认选择上两者积极效果相当,但在回忆书写上,手写明显优于拼音输入。另外,经纸笔手写和键盘拼音输入复习和学习的汉字,其记忆保持随时间变化的趋势一致。以上结果说明了对具有书面语言经验的儿童,拼音输入与手写都有助于形成和巩固汉字在心理词典中的义音形联结,但手写动作更有利于汉字从正字法代码向书写动作程序的转换;"提笔忘字"现象可能是正字法遗忘的结果,并非由使用拼音输入法造成。     

Does It Matter Whether One Takes a Test on an iPad or a Desktop Computer?

To investigate possible iPad related mode effect, we tested 403 8th graders in Indiana, Maryland, and New Jersey under three mode conditions through random assignment: a desktop computer, an iPad alone, and an iPad with an external keyboard. All students had used an iPad or computer for six months or longer. The 2-hour test included reading, math, and writing items adapted from released NAEP 8th grade tests. Overall, no significant difference was found on the reading, math, or writing section scores or section response time among the three mode conditions. Further, roughly comparable numbers of students reportedly favored testing using an iPad or a desktop computer, but using a preferred mode did not lead to significantly higher section scores. These findings suggest that there is no noticeable disadvantage associated with taking a test on an iPad than on a desktop computer for experienced users of these two studied devices.
