熟悉性:基于知觉还是语义流畅性加工

该文运用任务分离法和Remember/Know程序,分别以图形和汉词为材料,研究集中注意和重度分散注意条件下内隐记忆和熟悉性的关系,以揭示外显记忆中熟悉性的属性,结果发现:(1)知觉性内隐记忆在集巾注意和蕈度分散注意下差异不显著,再认中的熟悉性在这两种注意水平下差异显著;(2)概念性内隐记忆、线索回忆中的熟悉性在两种注意水平下差异均显著.据此熟悉性和知觉性内隐记忆相分离,与概念性内隐记忆未出现分离,从而可以推测外显记忆中的熟悉性主要受语义流畅性加工调节.     

The Interactive Effects of Impulsivity and Negative Emotions on Adolescent Nonsuicidal Self‐injury: A Latent Growth Curve Analysis

This study employed latent growth curve analysis to evaluate the interactive effects of two specific facets of impulsivity (i.e., negative urgency [NU] and premeditation [PRE]) and negative emotions (NE) on the developmental trajectory of nonsuicidal self‐injury (NSSI) among 3,453 (57% females) Chinese community adolescents. Participants completed questionnaires assessing NSSI, NU, PRE, and NE (i.e., depression, anxiety, and stress) at three waves of time. The initial levels of NE and NU significantly predicted the initial level of NSSI. Changes in NE and NU significantly predicted change in NSSI. Moreover, the initial levels of NU and PRE significantly moderated the relationship between the initial levels of NE and NSSI, such that among individuals with higher NU or less PRE, the three NE were associated with a higher level of NSSI. Additionally, among individuals with a faster increase in NU, depression and anxiety were associated with a faster increase in NSSI. These findings suggest that adolescents with trait impulsivity, especially in the form of NU, are more vulnerable to the engagement in NSSI.     

客体投影方式对空间问题解决和再认的影响

通过设置四种实验条件,旨在阐明空间问题解决和再认的水平是如何受到客体不同投影方式的影响。除进一步支持了正投影问题的解决是以一个具有三维结构特性的心理表征为基础而并非是对二维正投影信息进行了充分识别的观点外,研究结果还表明：（１）这个具有客体三维结构特性的心理表征是建构于对正投影问题解决而非轴测投影图的再认过程中;（２）正投影问题解决的复杂性显著地高于轴测投影图问题解决而且一个建构于正投影问题解决中     

表象运动推断加工子系统特性的实验研究

通过检测２０名飞行员和１０名老年被试及其控制组的表象运动推断加工水平,结果表明：（１）除较易任务上的反应时与其控制组构成显著差异外,飞行员在表象运动推断的加工速度和正确方面均未表现出较大的优势;（２）与较易水平上的任务相比,老年组在较难水平上表象运动推断加工的速度和正确性方面均未同青年组构成显著差异;（３）与青年组被试相比,老年 在加工耗时量方面受加工量增大的影响较大,且在反应正确性方面与青年线相     

知识验证信念对于多文本阅读理解的影响机制:阅读策略的中介效应和主题知识的调节效应

为厘清知识验证信念对于多文本阅读理解的影响机制,本研究构建了有调节的中介模型。采用知识验证信念量表、主题知识问卷和阅读策略量表,对于173名大学生进行调查,并要求其在多文本阅读理解之后进行开放问题回答。结果显示：精致化策略和信息收集策略在知识验证信念对于多文本阅读理解的影响中起部分中介作用;知识验证信念对于精致化策略的预测作用受到主题知识的调节。该结果不但展示了知识验证信念对于多文本阅读理解的间接影响机制,也提示了主题知识的作用在于提供了选择复杂策略的自由。     

初中二年级学生学习困难、人际关系、自我接纳对心理健康的影响

以134名初中二年级学生为被试,采用协方差结构模型对学习困滩、人际关系、自我接纳与心理健康的关系进行研究.结果表明:(1)学习困难对心理健康有显著的负面影响;自我接纳对心理健康有显著的正面影响.(2)学习困难对亲子关系和师生关系有显著负面影响.(3)亲子关系对自我接纳有显著的正面影响.     

工作记忆和风险取向类型对情感决策的影响

本研究采用爱荷华赌博任务(Iowa Gambling Task,IGT)范式,探究工作记忆在情感决策过程中的作用,以及风险取向类型与工作记忆的作用机制。以88名大学生为被试,采用自变量2(风险取向类型:风险偏好/风险规避)×2(工作记忆负荷:无负荷/有负荷)的混合实验设计。结果发现,高工作记忆负荷会降低被试的IGT成绩;工作记忆负荷和风险取向类型存在交互作用,即对于风险偏好型被试,工作记忆负荷对IGT损失敏感性的干扰并不明显,但对于风险规避型被试,高工作记忆负荷时的IGT损失敏感性比低工作记忆负荷时的更差。这些结果表明工作记忆和风险取向均会影响个体的情感决策。     

Social Trust: Fairness Matters More Than Homogeneity

This article explores whether homogeneity or fairness better explains generalized interpersonal trust across countries. Although some research suggests that ethnic diversity and income heterogeneity have a negative impact on social trust, I argue that cross‐national variations in social trust are better explained by fairness: fair procedural rules (democracy), fair administration of rules (freedom from corruption), and fair income distribution (relatively equal but also unskewed). This expectation is confirmed by a multilevel analysis of data from the World Values Surveys and European Values Study covering 170,000 individuals in 80 countries.     

Components representation of negative numbers: evidence from auditory stimuli detection and number classification tasks

Past research suggested that negative numbers could be represented in terms of their components in the visual modality. The present study examined the processing of negative numbers in the auditory modality and whether it is affected by context. Experiment 1 employed a stimuli detection task where only negative numbers were presented binaurally. Experiment 2 employed the same task, but both positive and negative numbers were mixed as cues. A reverse attentional spatial-numerical association of response codes (SNARC) effect for negative numbers was obtained in these two experiments. Experiment 3 employed a number classification task where only negative numbers were presented binaurally. Experiment 4 employed the same task, but both positive and negative numbers were mixed. A reverse SNARC effect for negative numbers was obtained in these two experiments. These findings suggest that negative numbers in the auditory modality are generated from the set of positive numbers, thus supporting a components representation.     

反刍思维的脑功能网络机制

反刍思维是指个体在经历了消极生活事件后不由自主地反复思考该事件的产生原因、经过和结果, 表现出负性自我参照加工、消极情绪性以及持续性的特点。采用脑功能网络分析方法, 研究者发现反刍思维的上述三个特点分别与默认网络内部的异常活动模式、突显网络功能连接的改变以及注意相关网络之间的异常耦合有关。未来研究应进一步明确反刍思维与相关脑网络活动之间的因果关系, 探究反刍思维脑功能网络的结构基础, 同时也应关注反刍思维及其脑网络的老龄化特征, 并致力于探索有效干预反刍思维的神经调控技术。
