Influence of the large–small split effect on strategy choice in complex subtraction

Two main theories have been used to explain the arithmetic split effect: decision‐making process theory and strategy choice theory. Using the inequality paradigm, previous studies have confirmed that individuals tend to adopt a plausibility‐checking strategy and a whole‐calculation strategy to solve large and small split problems in complex addition arithmetic, respectively. This supports strategy choice theory, but it is unknown whether this theory also explains performance in solving different split problems in complex subtraction arithmetic. This study used small, intermediate and large split sizes, with each split condition being further divided into problems requiring and not requiring borrowing. The reaction times (RTs) for large and intermediate splits were significantly shorter than those for small splits, while accuracy was significantly higher for large and middle splits than for small splits, reflecting no speed–accuracy trade‐off. Further, RTs and accuracy differed significantly between the borrow and no‐borrow conditions only for small splits. This study indicates that strategy choice theory is suitable to explain the split effect in complex subtraction arithmetic. That is, individuals tend to choose the plausibility‐checking strategy or the whole‐calculation strategy according to the split size.     

Evidence of a Flynn Effect in Children's Human Figure Drawings (1902–1968)

The Flynn effect is the long-term trend for scores on tests of cognitive ability to increase across cohorts. Several samples of children's human figure drawings, published in 1902, 1926, 1963, and 1968, are examined for evidence of a Flynn effect. Results show that larger percentages of children draw more complete human figures over the course of the 20th century.     

利他行为的内隐启动研究

通过视觉与组词任务启动范式的两个实验考察了利他人物形象与利他词语对利他行为的内隐启动效应。结果发现,完成利他人物形象视觉启动(实验1)与完成利他组词任务启动(实验2)的实验组被试,在独裁者分配任务中分配给他人的钱数显著多于控制组被试。研究结果表明:利他人物形象视觉和利他语义组词都可以使个体的利他行为被显著直接无意识启动,即内隐启动。研究对设计能更好地启动人们的利他行为的一般情境有重要的启示。     

启动任务中语言经验对藏-汉双语者主导语的影响

采用语义启动任务及藏语与汉语语义相关词和无关词对,探究语言经验能否改变熟练藏-汉双语者的母语主导优势和双语语义表征方式。结果表明,1)无论启动词为藏语还是汉语,藏-汉双语者对汉语L2目标词的加工速度和正确率均显著好于藏语L1,存在语义启动效应; 而在藏语目标词条件下则未发现显著的语义启动效应; 2)藏语到汉语的语义启动效应大于汉语到藏语的启动效应。结果表明,藏-汉双语者的汉语经验对藏语词的表征有影响,但汉语还不能完全替代母语藏语为主导语,结果在一定程度上支持Kroll的RHM模型和Green的ICM模型。     

Redundancy gain for categorical targets depends on display configuration and duration

Redundancy gain is an improvement in speeded target detection when the number of targets associated with a single response is increased within a single display. The effect has been clearly demonstrated with specific targets, but it is not clear if it occurs in categorization tasks with non-identical targets. The current study tested the effect of target redundancy on speed and accuracy in a go/no-go categorization task. Targets were digits tilted 45° to the left, and were displayed in unilateral, bilateral, or central displays for either 1500?ms or 100?ms. Redundancy gain only occurred for brief targets displayed bilaterally in the upper visual field. The results indicate that redundancy gain is possible for categorization tasks with some bilateral configurations, supporting a role for interhemispheric processing in redundancy gain. Additionally, the results may indicate that processing strategies mask redundancy gain when participants can view targets for a long period of time.     

授权型领导行为对员工任务绩效的非线性影响机制

授权型领导契合了组织扁平化的时代背景,受到理论界与实践界的追捧。但授权型领导与任务绩效的关系存在矛盾性研究结论。基于自主性成本论,提出授权型领导通过自我决定感的曲线路径间接对任务绩效产生影响。通过对478对上下级配对数据的分析发现：授权型领导与任务绩效存在倒U型关系;授权型领导正向影响员工自我决定感;员工自我决定感与任务绩效存在倒U型关系;授权型领导通过自我决定感的曲线路径间接对任务绩效产生影响。     

非工作时间使用通信技术处理工作的“双刃剑”效应及心理机制

在当前的互联网时代下,个体“在非工作时间使用通信技术处理工作”的现象已经非常普遍,并因其对个体日常工作生活适应可能产生的深远影响而受到研究者的广泛关注。基于对该领域已有研究文献的全面回顾,本文着重探讨了非工作时间使用通信工具处理对个体工作生活适应的“双刃剑”效应及效应发生的心理机制,并对该领域未来的研究方向进行了针对性的展望。     

时间赋义对数字空间表征的影响：来自数字线估计任务的证据

数字线估计任务的大量研究以纯数字为研究对象而忽视了赋义数字。本研究以Siegler等的数字线估计任务为原型,探讨在对数字时间赋义条件下小学二、四和六年级儿童的数字表征形式是否发生变化。结果表明,小学二年级是0-1000范围内数字表征从对数形式转换为线性形式的转折点,对数字赋予时间含义后,三个年级均出现了赋义效应。在线性模型和对数模型中时间赋义的作用相反,时间赋义表现出抑线升对（抑制线性模型提升对数模型解释力）的效果。

大学生反刍思维对消极情感和积极情感的影响——以孤独感和情绪智力为例

以331名大学生为被试,采用反刍思维量表、孤独感量表和情绪智力量表,考察了三者之间的关系,以说明反刍思维既可以对个体情绪产生消极影响,也可以对其产生积极影响。结果表明,在中国大学生群体中,反刍思维的反省维度得分高于抑郁相关和沉思维度得分;反刍思维总分及三个维度都可以正向预测孤独感;反刍思维的抑郁相关维度负向预测情绪智力水平,反省维度正向预测情绪智力;情绪智力分别在反刍思维、抑郁相关和沉思三个变量与孤独感之间的关系中起着调节作用,可以缓解三个变量对孤独感的预测作用。
