Carrot eaters or moving heads: inductive inference is better supported by salient features than by category labels

How do words affect generalization, and how do these effects change during development? One theory posits that even early in development, linguistic labels function as category markers and thus are different from the features of the stimuli they represent. Another theory holds that early in development, labels are akin to other features, but that they may become category markers in the course of development. We addressed this issue in two experiments with 4- to 5-year-olds and adults. In both experiments, participants performed a categorization task (in which they predicted a category label) and an induction task (in which they predicted a missing feature). In the latter task, the category label was pitted against a highly salient feature, such that reliance on the label and reliance on the salient feature would result in different patterns of responses. Results indicated that children relied on the salient feature when performing induction, whereas many adults relied on the category label. These results suggest that early in development, labels are no more than features, but that they may become category markers in the course of development.     

空气污染的不良效应及理论模型:环境心理学的视角

空气污染的不良效应不仅限于生理健康损害,还涉及认知功能、情绪和行为等多方面的消极影响。针对空气污染不良效应的形成机制,以往研究提出了环境应激模型和社会-环境交互模型,这些理论模型强调空气污染的不良效应不仅涉及污染的直接暴露程度,也取决于个体的身心状况以及他对空气污染的主观评价。基于以往研究的不足,尤其是环境心理学介入空气污染研究的可行性,未来研究可着眼于改进空气污染的心理学研究方法,开展空气污染的环境应激和风险感知研究。     

Spillover Effects of Emotional Labor in Customer Service Encounters Toward Coworker Harming: A Resource Depletion Perspective

This research examines how the implications of emotional labor can transfer from customer encounters to coworker interactions using temporally lagged data from a sample of frontline service employees. The results show that surface acting in customer service encounters is positively, and deep acting is negatively, related to ego depletion. Employees’ ego depletion, in turn, is positively associated with their interpersonally harmful behavior toward coworkers. Hence, ego depletion appears as a mediating variable that translates the implications of distinct emotional labor strategies into coworker harming. Moreover, emotion regulation self‐efficacy moderates the role of surface acting. The positive indirect relationship between surface acting and coworker harming, via ego depletion, is buffered among employees with higher emotion regulation self‐efficacy. These findings shed new light on the complex and far‐reaching consequences of emotional labor. We demonstrate the relevance of emotional labor to third parties not directly involved in customer service encounters and highlight important mediators and boundary conditions of these indirect relations.     

The effect of working memory load on the SNARC effect: Maybe tasks have a word to say

We investigated the effect of working memory load on the SNARC (spatial–numerical association of response codes) effect under different number judgment tasks (parity judgment and magnitude comparison), using a novel dual task. Instead of exerting load over the whole block of number judgment trials, in this dual task, number judgment trials were inserted into each interstimulus interval of an n-back task, which served as the working memory load. We varied both load type (verbal and spatial) and amount (1-load, 2-load, and 3-load). The results indicated that the SNARC effect disappeared even under the 1-load condition for a parity judgment, regardless of the type of load. However, during the magnitude comparison task, the SNARC effect increased with increasing load amounts under spatial load conditions; under verbal load conditions, the SNARC effect decreased with increasing amounts of load, and disappeared during the 3-load task. The difference between the parity and magnitude tasks was not attributable to the interval stimuli or task switching. These findings confirm that different spatial–numerical associations for comparing numerical magnitudes and judgments of parity have different needs with respect to working memory resources.     

情绪刺激在虚假记忆产生中的作用:来自ERP与眼动的联合证据

摘 要 为探索情绪刺激如何影响虚假记忆及其在分离虚假记忆与真实记忆神经活动中的作用,以IAPS图片为标准情绪刺激,19名大学生为被试,使用DRM实验范式,从行为、眼动和ERP三个方面进行了联合分析。结果发现,情绪的唤醒度和效价都能促使虚假记忆的产生,只是唤醒度影响时程更早。眼动和ERP的联合分析还发现了在情绪刺激下虚假记忆与真实记忆在神经活动层面上存在差异：早期虚假再认图片比真实再认图片需要更深的加工来实现对目标的识别;晚期虚假再认需要更多的信息搜索、比较等加工来完成其决策行为。     

注意瞬脱神经机制的研究

在很短的时间间隔内连续呈现两个目标刺激时,被试对第二个目标刺激的正确报告率显著下降,这种现象就是注意瞬脱.该文简述了注意瞬脱的概念、容量有限性等方面,尤其详细介绍了注意瞬脱神经机制研究的新进展,并对今后的研究提出展望.     

两种类型数学困难儿童的执行水平

使用Crack the Code任务考察单纯型与混合型数学困难小学儿童的执行水平,结果发现:单纯型数学困难儿童在对认知资源要求较高的任务上的执行水平显著低于数学优良生,但在认知要求较低的任务上二者之间没有显著差异;混合型数学困难儿童执行水平最低,在两个难度水平执行任务上的表现均显著差于数学优良生、单纯型数学困难儿童.小学儿童执行水平年级差异似乎主要表现在认知负荷较高的任务上,1年级学生与3、5年级学生的执行水平存在显著差异.     

简单与复杂物理问题解决及状态元认知

本研究采用认知作业分析及问卷法,研究了中学生简单与复杂物理问题解决的表征机制及状态元认知结构。结果显示：(1)物理问题解决是对问题的表征状态不断转换的过程,其受认知主体信息的提取、转换、整合能力及状态元认知的影响;(2)中学生物理问题解决中的状态元认知主要由他的自我效能感、自我监测、策略系统三种成分构成;(3)复杂问题解决的关链是正确提取范畴性知识以形成对问题的深层表征。     

不同任务情境对幼儿心理理论表现的影响

本研究通过在三种不同实验条件下,系统比较60名幼儿在错误信念认识和表征变化任务上的表现。研究表明：ToM能力的表现模式可能随测验程序或被试样本的变化而变化;年龄小的幼儿在任务上的表现更可能受实验条件的影响;不同条件下幼儿关于自己的表征变化和他人的错误信念的认识均没有显著性差异。
