多目标追踪中基于运动信息的分组效应

本研究旨在探讨运动信息对多目标追踪的影响, 具体为考察多目标追踪中是否存在基于运动信息的分组效应, 以及不同类型表面特征(颜色和形状)对这一效应的影响。实验1发现多目标追踪中存在基于运动信息的分组效应, 并且这一分组效应是自动化的。实验2和实验3分别在不同颜色和不同形状组合条件下考察了基于运动信息的分组效应的稳定性, 结果都表明不同表面特征的组合不会干扰基于运动信息的分组效应的形成, 但其效应量都因表面特征的出现而缩减。整体而言, 多目标追踪中存在基于运动信息的自动化分组效应, 并且这一效应是格式塔法则中共同命运律的具体表现, 能稳定存在于不同表面特征组合之间。     

抑制控制训练对手机依赖大学生的干预效果

依照手机成瘾倾向量表得分及手机使用时间记录从548名被试中筛选出60名手机依赖大学生,将其随机分配到抑制控制训练组和非训练组进行实验。预期通过抑制控制训练提升手机依赖大学生抑制控制能力,降低其手机依赖水平。结果发现：训练组被试在接受为期8周的抑制控制训练任务后,手机依赖总分、手机使用时间和非训练组相比显著降低,抑制控制能力显著提升。结果表明抑制控制训练对手机依赖大学生的干预效果明显。     

Building blocks of idea generation and implementation in teams: A meta-analysis of team design and team creativity and innovation

Although organizations increasingly rely on teams to innovate, little systematic knowledge exists about how to design teams to do so. Building on the model of collaborative creativity and innovation and synthesizing findings from published and unpublished studies, this meta-analysis examines the role of team design on team creativity and innovation. We used random-effects meta-analysis to cumulate the correlations between different features of team design and team creativity or team innovation from 134 field studies representing 11,353 teams and 35 studies representing 2,485 student teams. We found that team tenure is curvilinearly related, autonomy-supportive leadership, task interdependence, and goal interdependence are positively related, and demographic diversity and team size are unrelated to team creativity and innovation. Examining meta-analytic path models, we found that task interdependence and supportive leadership positively relate to team creativity and innovation via team collaboration and team potency. In accounting for the literature, we found a dearth of studies examining team processes, some types of diversity such as racial diversity, and the role of team member turnover. We conclude by providing directions for future research and practical guidance about increasing team creativity and innovation through team design.     

老年人情景记忆更新的改变：竞争记忆的回溯性干扰

记忆更新是获取新知识的一种重要能力。大量研究显示老年人情景记忆受损,但鲜有研究探讨老年人情景记忆更新模式的改变。研究在匹配了老年人和年轻人编码程度的前提下,探讨情景记忆更新的老化效应及其潜在的认知机制。我们对AB-AC记忆更新范式进行了创新,同时考察了在项目改变和位置改变条件下的老化效应,并在测试阶段纳入诱饵选项,进一步排除编码程度带来的影响。研究结果显示年轻人能对A-B和A-C记忆分离存储,而老年人更多地受到回溯性记忆干扰,即在A-B测试中出现C的闯入,并且该干扰效应显著地大于诱饵刺激带来的影响。研究结果表明,在年轻人和老年人编码程度匹配的情况下,年轻人的记忆更新通过记忆分化来实现,而老年人更多地受到竞争记忆的回溯性干扰。     

认知冲突协调问题与心智的架构

心智架构或认知架构是指一个功能相对完整的认知系统的基本组织结构。经典认知科学的理论或模型大多采纳了某种类似于冯·诺依曼式计算机体系结构的心智架构,即认知系统由一些各司其职的心理模块与一个负责整合与协调的中枢部门所构成。进化心理学的众量模块性论题对经典认知科学的心智架构观提出了严厉挑战,并引发了许多争议。本文提出认知冲突协调问题是任何一个足够复杂的认知系统均需要处理的基本问题,并以此来审视关于心智架构的论战,指出此问题对众量模块性论题构成了严重的困难。     

大学生主动拖延水平与成就STROOP干扰效应

此研究检验了主动拖延行为与成就动机词语间的STROOP干扰效应。选取150名大学生作为被试。通过中文修订版的主动拖延量表问卷筛选出30名被试完成修正的STROOP任务。结果发现,主动拖延水平高的被试在所有类型词语中的反应都比主动拖延水平低的被试快,在成就动机词语上面差异更为显著,主动拖延水平高的被试表现出了明显的STROOP干扰,即对于成就动机词的反应时明显较慢。     

Emerging Practices of Counseling and Psychotherapy in China: Ethical Dilemmas in Dual Relationships

A qualitative study was conducted with 48 Chinese counselors and psychotherapists who were interviewed in 2006 and an independent sample of 50 participants who responded to a survey in 2014. This study aims to explore how the new emerging expansion of mental health practice is related to issues and challenges of dual role relationship and how the well-engrained values and social characteristics of Chinese culture influences perceptions and resolution of ethical dilemmas. The participants identified similar dual relationships in 2006 and 2014: (a) Incidental boundary crossings, a sexual or romantic relationship, a dual social relationship, and a professional dual relationship were the most frequently reported types of dual relationships encountered by Chinese practitioners, and (b) the socioeconomic and cultural context and the development trajectory of counseling and psychotherapy in China play a significant role in shaping practitioners’ behaviors. The comparison of the data in 2006 and 2014 indicated that practitioners in psychotherapy and counseling have an improved awareness and understanding of ethical issues, evidenced by the decreasing cases of romantic and sexual relationships and increasing cases of social dual relationships influenced by the interrelatedness of traditional Chinese culture.     

Consolidating behavioral and neurophysiologic findings to explain the influence of contextual interference during motor sequence learning

Motor sequence learning under high levels of contextual interference (CI) disrupts initial performance but supports delayed test and transfer performance when compared to learning under low CI. Integrating findings from early behavioral work and more recent experimental efforts that incorporated neurophysiologic measures led to a novel account of the role of CI during motor sequence learning. This account focuses on important contributions from two neural regions—the dorsal premotor area and the SMA complex—that are recruited earlier and more extensively during the planning of a motor sequence in a high CI context. It is proposed that activation of these regions is critical to early adaptation of sequence structure amenable to long-term storage. Moreover, greater CI enhances access to newly acquired motor sequence knowledge through (1) the emergence of temporary functional connectivity between neural sites previously described as crucial to successful long-term performance of sequential behaviors, and (2) heightened excitability of M1—a key constituent of the temporary coupled neural circuits, and the primary candidate for storage of motor memory.     

Impact of material vs. experiential purchase types on happiness: The moderating role of self‐discrepancy

Most literature suggests that consumers are happier when they spend their money on experience, rather than material purchases, on the premise that consumers may evaluate material possessions largely on the basis of their functional utility and ability to fulfill basic human needs; experiential consumption reportedly fulfills mainly psychological needs. The present research addresses material purchases that fulfill not only functional but also psychological needs (e.g., status purchase). The results reveal that consumers with high self‐discrepancy are more apt to derive happiness from material status purchases than those with low self‐discrepancy (Experiments 1 and 2); this effect is mediated by the motives for goal pursuit (Experiment 3), as triggered by the desire to narrow the gap between the actual self and an ideal self.
