Fine motor skill proficiency in typically developing children: On or off the maturation track?

Fine motor skill proficiency is an essential component of numerous daily living activities such as dressing, feeding or playing. Poor fine motor skills can lead to difficulties in academic achievement, increased anxiety and poor self-esteem. Recent findings have shown that children’s gross motor skill proficiency tends to fall below established developmental norms. A question remains: do fine motor skill proficiency levels also fall below developmental norms? The aim of this study was to examine the current level of fine motor skill in Irish children. Children (N = 253) from 2nd, 4th and 6th grades (mean age = 7.12, 9.11 and 11.02 respectively) completed the Fine Motor Composite of the Bruininks Oseretsky Test of Motor Proficiency 2nd Edition (BOT-2). Analysis revealed that only 2nd grade children met the expected level of fine motor skill proficiency. It was also found that despite children’s raw scores improving with age, children’s fine motor skill proficiency was not progressing at the expected rate given by normative data. This leads us to question the role and impact of modern society on fine motor skills development over the past number of decades.     

Short-term and long-term relationships between reflection and performance in teams: evidence from a four-wave longitudinal study

Previous theory and research suggest that team reflection is beneficial for team performance. We argue that results remain inconclusive because prior studies have not accounted for the dynamic nature of this relationship. This paper addresses this research gap by examining time-specific relationships among variables and the intra-team variability of changes across time. In a four-wave longitudinal field study with 97 teams (N = 453 team members) performing a business simulation task, short-term (i.e., autoregressive, cross-lagged effects) and long-term (i.e., latent trajectories) relationships between team reflection and performance were explored. We found evidence that reflection had negative autoregressive effects and that there were direct positive short-term relationships between reflection and performance. Reflection trajectories were seen to decline across time and performance trajectories to increase across time. In addition, teams with either low initial reflection or low initial performance showed higher increases in reflection across time, whilst higher increase in reflection was negatively related to change in performance. Findings are discussed with respect to how they extend the previous literature and what directions they suggest for future research.     

经验取样法——一种收集“真实”数据的新方法

经验取样法是一种有效的密集纵向研究数据收集方法。该方法的优点正逐渐被广大研究者所认同,国外运用经验取样法取得的研究成果越来越多,而国内学者对经验取样法的研究尚处于探索阶段,运用此方法的实证研究更是凤毛麟角。通过对《应用心理学期刊》(Journal of Applied Psychology)最近5年(2010~2014年)发表的26篇采用经验取样法的实证研究论文的内容分析,发现这些文章全面体现了经验取样法的特点、研究内容、样本量、激励方式、数据收集和操作过程等该方法的操作要素。对其进行总结不仅有利于对经验取样法在组织行为学中的应用状况进行总结,而且也能促进这一方法在未来的组织行为学和人力资源管理中的发展和应用。     

场景知觉中的眼动分析指标:基于注视和眼跳视角

眼动范式是场景知觉研究的重要方法之一,可以通过对场景知觉过程中眼动变化的实时记录,真实地反映场景信息加工的内在心理机制;然而,人们的心理活动是极其复杂的,与之相应的眼动指标也具有多样性和复杂性。对眼动指标的分析,有不同的分析维度,比如整体和局部、时间和空间等。本文回顾了已有的眼动指标分类,并尝试从注视和眼跳的视角对场景知觉过程中的眼动指标进行分类。在此基础上,从界定标准、心理学意义、研究应用等方面对相应的眼动指标进行分析和介绍,最后提出了眼动指标分析和应用可能存在的问题,以及未来研究可能拓展的领域。     

无关信息对注意控制的影响

本研究采用眼动技术,通过两个实验探讨不同加工水平的任务无关信息对注意控制中不同成分的影响。结果表明,无关信息对注意警戒和定向的影响更为明显,不论是在知觉水平（运动方向）上,还是在概念水平（语义）上,无关信息均产生阻碍效果;但语义信息比知觉水平信息的干扰作用出现的更晚。无关信息对执行过程的影响与无关信息性质有关,同类别无关信息作用更加明显。     

SWIFT-Ⅱ：阅读中眼跳发生的动力学模型

文章阐述了SWIFT模型的最新进展—SWIFT-Ⅱ模型的基本观点。SWIFT-Ⅱ模型能够在更为详细的水平上分析模型的模拟结果,也较好地解释了词长和词频效应、注视时间的分布、回视、再注视、初次登陆位置等眼动现象。最后对SWIFT-Ⅱ模型与E-ZReader模型进行了比较。     

Aggressive behavior among girls and boys during middle childhood: predictors and sequelae of trajectory group membership

Using longitudinal data spanning early elementary through middle school, aggression behavior trajectory groups were identified for boys and girls. Early elementary school predictors of trajectory group membership were examined as well as whether trajectory group predicted physical aggression, covert delinquency, and substance use in 9th grade. Semiparametric group modeling identified aggression behavior trajectory groups. We identified four aggression trajectory groups for both genders described as “not involved,” “low,” “moderate,” and “high.” Attention problems, family conflict, and low school commitment and attachment were predictors of membership in higher aggression groups for both boys and girls. Low family involvement and low parental education predicted membership in higher aggression groups for boys; while depression, low‐income status, and having a single parent predicted higher aggression group membership for girls. For both boys and girls, few risk predictors distinguished between the moderate and high aggression trajectories except that low school commitment and having a teen mother were significant predictors of being in the high group for girls, and low parental education and income were significant predictors of being in the high group for boys. Membership in the higher aggression trajectory groups predicted involvement in violent behaviors, covert delinquency, and substance use in 9th grade. Findings suggest that children who display an early trajectory of high levels of aggressive behavior are more likely to continue involvement in later problem behaviors. Second‐grade predictors suggest commonality of risk across genders and provide evidence of modifiable targets for preventive interventions. Aggr. Behav. 32:1–15. 2006. © 2006 Wiley‐Liss, Inc.     

内隐序列学习表征机制探究：眼动证据

内隐序列学习的表征机制是内隐学习研究领域的基本问题, 还存在争议。采用眼动追踪技术, 通过3个实验探讨内隐序列学习的表征机制。结果发现, 知觉序列混合眼跳和反应序列混合眼跳条件下发生序列学习; 朝向眼跳和反向眼跳条件下发生序列学习; 有、无分心反向眼跳下发生序列学习, 两者序列学习量差异不显著。整个研究表明, 内隐序列学习的表征依赖于序列信息。     

国内追踪数据分析方法研究与模型发展

群组发展模型——干预研究的新方法

群组发展模型(group-based trajectory model,GBTM)是一种用于研究群体异质性的新方法,旨在识别群体内遵循不同发展轨迹的亚组,并描绘亚组成员特征。这一模型为干预研究提供了新的研究视角,群组发展模型不仅可以探讨干预是否引起分组比例变化,也关注干预对个体的发展轨迹的影响,并评估干预对不同轨迹组的效果差异。
