亲子和同伴依恋对初中生心理素质发展的影响:个人中心分析视角

本研究旨在考察初中生心理素质的发展轨迹以及亲子和同伴依恋对其的影响。三所中学的442名初一学生和501名初二学生参加了三轮追踪调查,初测平均年龄M =12.83,SD =0.74。结果发现,初一学生,心理素质发展轨迹可分为中-降组（79%）和高-升组（21%）两个亚群组;且初一上父子依恋或母子依恋水平越高,心理素质发展轨迹为高-升组的概率大于中-降组。初二学生,心理素质发展轨迹可分为低-稳组（84%）和高-升组（16%）两个亚群组;且初二上父子依恋水平越高,心理素质发展轨迹为高-升组的概率大于低-稳组。结果表明初中生心理素质发展轨迹可以分为不同的亚群组类型,父子依恋和母子依恋对初中生心理素质发展有积极作用,这些发现对于初中生心理素质的培养具有一定的指导意义。     

多变量追踪研究的模型整合与拓展：考察往复式影响与增长趋势

追踪研究当中, 交叉滞后模型可以探究多变量之间往复式影响, 潜增长模型可以探究个体增长趋势。对两类模型进行整合, 例如同时关注往复式影响与个体增长趋势, 同时可以定义测量误差、随机截距等变异成分, 衍生出随机截距交叉滞后模型、特质-状态-误差模型、自回归潜增长模型、结构化残差潜增长模型等。以交叉滞后模型和潜增长模型分别作为基础模型, 从个体间/个体内变异分解的角度对上述各类模型梳理, 整合出此类模型的分析框架, 并拓展建立“因子结构化潜增长模型(factor latent curve model with structured reciprocals)”作为统合框架。通过实证研究(早期儿童的追踪研究-幼儿园版, ECLS-K), 建立21049名儿童的阅读和数学能力的往复式影响与增长趋势。研究发现, 分离了稳定特质的模型拟合最优。研究也对模型建模思路和模型选择提供了建议。     

Social cognitive predictors of academic persistence and performance in engineering: Applicability across gender and race/ethnicity

We examined the utility of social cognitive variables in the longitudinal prediction of academic persistence and success of engineering students. The participants, 908 students enrolled in engineering majors at two state universities, completed measures of academic support, self-efficacy, outcome expectations, interests, satisfaction, positive affect, and intended persistence at the end of each of their first four semesters. In the current study, students' first and second semester responses were used to predict persistence and grade performance in engineering by the end of six semesters. Path analytic findings indicated that second-semester persistence intentions, satisfaction with the major, self-efficacy, and social support each produced direct paths to persistence. Objective ability (mathematics SAT scores), outcome expectations, and interests were linked to persistence indirectly via their relations to other variables in the model. In addition, self-efficacy and objective ability jointly predicted grade performance. Results were stable across gender and racial/ethnic groups. Implications for research and practice on academic adjustment in engineering are considered.     

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。     

Actions and outcomes: two aspects of agency

Agency can be construed as both the manner in which autonomous individuals embark on particular courses of action (or inaction), and the relationship between such agents and the outcomes of the courses of action on which they embark. A promising strategy for understanding both senses of agency consists in the combination of a modal logic of agency and branching time semantics. Such is the strategy behind stit theory, the theory of agentive action developed by Nuel Belnap and others. However, stit theoretic evaluations of the agentive relationship between agents and outcomes that are uncertain—due to either the presence of indeterminism, or the possible intervention of other agents—yield counterintuitive results. This paper develops a pair of alternative operators (the “act” operators) for modeling agency with respect to uncertain outcomes. Unlike the stit-theoretic model, the act-theoretic model of agency with respect to a particular state of affairs does not require that the state of affairs be realized in every possible history. If the state of affairs in fact obtains in the actual history, and its obtaining was dependent on the agent’s pursuing a particular course of action, then the agent is deemed agentive under act theory.     

The Indetermination of Reason and the Roleof the Will in Aquinas's Accountof Human Freedom

Thomas Aquinas argues that human choices are made by the will and reason working together. It is easy to misinterpret his argument and suppose that the reason alone works out what should be done while the will simply ratifies this. Instead Aquinas believes that in practical matters the reason is often undetermined since it arrives at many simultaneous conclusions. This is the often unacknowledged heart of Aquinas's account of freedom. All these simultaneous rational conclusions derive from the objective circumstances of the world; each one could give rise to a different rationally justified course of action; yet only one can be acted upon. The reason cannot decide between them. It is the will that accepts and affirms one of these conclusions and gives force to the reasonableness of one course of action. This is why a choice is always rational and personally willed – which is what makes it free. The indetermination of reason is what allows the future to be open-ended for the deliberating agent; it allows past and present to be interpreted in different ways, each of which has its own coherence and rationality. In this way Aquinas's account of human freedom avoids both an irrational voluntarism and a deterministic intellectualism
