大脑电刺激在听觉语言加工研究中的应用

大脑电刺激是历史悠久但近年来才广泛应用在人类被试上的实验技术。通过对颅内刺激位点进行电刺激, 并分析引发的暂时性行为功能变化和记录位点的电位活动, 大脑电刺激技术可以揭示认知加工过程中脑区内的功能作用与脑区间的有效连接。通过对听觉语言加工过程相关的丘脑、听觉皮层、高级语言皮层进行电刺激, 现有研究发现了各个脑区的不同功能特点以及不同脑区间的信息传递机制, 为进一步探索听觉语言加工的神经机制提供了新的视角。     

THE EXPERIENCE CYCLE AND THE SEXUAL RESPONSE CYCLE: CONCEPTUALIZATION AND APPLICATION TO SEXUAL DYSFUNCTIONS

Abstract

The sexual response cycle as a heuristic for understanding sexual responding has emerged from sexuality literature. Another cyclic heuristic, the experience cycle, has been developed in Personal Construct Psychology (PCP) literature to conceptualize how persons anticipate, encounter, and then evaluate experiences in terms of validation/invalidation and potential need for construct system change. The present article maps these two cycles onto each other to offer a PCP framework for understanding sexual responding, sexual dysfunctions, and therapy targeting sexual function.     

Experiencing malevolent voices is associated with attentional dysfunction in psychotic patients

Inattention in people with schizophrenia is common. However, there has been little research on the association between inattention and auditory hallucinations. The aim of the study was to investigate how inattention is affected by beliefs about voices as benevolent and malevolent and perceived control of voices. A total of 31 patients who experienced auditory hallucinations and who met the criteria for schizophrenia or other psychosis completed the attention subscale of the Scale for the Assessment of Negative Symptoms (SANS) and the Connors’ Continuous Performance Test II (CCPT‐II). The revised Beliefs About Voices Questionnaire (BAVQ‐R) was used to assess malevolent and benevolent beliefs about voices, and severity of auditory hallucinations (the Psychotic Symptom Rating Scales; PSYRATS) was used to assess perceived control of voices and frequency of voices. Levels of depression (the Beck Depression Inventory; BDI), anxiety (the Beck Anxiety Inventory; BAI), severity of overall psychiatric symptoms (the Brief Psychiatric Rating Scale; BPRS), and severity of negative symptoms (SANS) were assessed to control for their potential confounding effects. The relations between the variables were explored with correlations and multiple hierarchical regression analyses. The results indicated that more malevolent, but not more benevolent, beliefs about voices predicted lower levels of attention, independently of general psychiatric symptoms and various other psychotic symptoms such as frequency of and perceived control of voices. These findings suggest an important relationship between malevolent beliefs about voices and levels of inattention. The possible impact of changing beliefs about voices to improve attentional functioning is discussed.     

错误后减慢理论模型述评

错误后减慢是指错误后正确反应与正确后正确反应相比反应时显著延长的现象.目前研究者已经发现错误后减慢、错误后正确率提高以及错误后干扰效应减少三种错误调控行为,其中错误后减慢是最稳定的错误后行为表现.早期研究主要从冲突监控理论、激活抑制假说、强化学习理论和失匹配理论等角度解释该现象,近年来,研究者又提出了注意朝向理论和评估适应假说.对于该领域未来的研究可以从错误类型、无意识加工、个体差异、新的分析技术的运用方面考虑,以便全面揭示错误后减慢现象的本质.     

集体主义与贿赂

贿赂是指财物由行贿者向受贿者转移, 公共权力由受贿者向行贿者的暂时转移, 并涉及到为私利而滥用公共权力的过程。研究者认为集体主义是影响贿赂的文化心理根源, 而实证研究发现集体主义与贿赂的关系受到两个方面因素的影响。一方面贿赂的研究视角影响集体主义与贿赂的关系。研究一致证明集体主义促进贿赂行为意向。然而虽然大部分研究表明集体主义与贿赂感知和贿赂态度正相关, 但仍有少量不一致结果。另一方面集体主义类型也影响着集体主义和贿赂的关系。前人关于集体主义对贿赂的作用机制仍以理论探讨为主, 实证研究主要以道德卷入和计划行为理论为基础。未来可以从澄清不同贿赂研究视角的区别与联系、区分不同类型集体主义与贿赂的关系以及关注集体主义对贿赂的作用机制这三个角度进行深入探索。     

Impulsivity,communication, and marital satisfaction in newlywed couples

The authors used a vulnerability–stress–adaptation framework to examine how and why impulsivity affects communication and marital satisfaction in a sample of 100 newlywed couples. We specifically examined the links between impulsivity and perceptions of conflict communication patterns and their associations with marital satisfaction. Using an actor–partner interdependence framework, the results demonstrated that impulsivity was negatively associated with one's own and partner's marital satisfaction. Impulsivity was also negatively associated with constructive communication and positively associated with destructive communication. Furthermore, mediation analyses showed that communication patterns mediated the impulsivity–satisfaction link. Taken together, these findings suggest that impulsivity is likely to lead to lower marital satisfaction, partly through its effect on communication between partners.     

阈下奖励调节认知控制的权衡

本研究采用奖励版的AX-CPT任务, 通过控制奖励线索和反馈的呈现方式, 设置出基线、阈上奖励、阈下奖励三种条件, 考察习得的奖励联结和奖励动机能否以潜意识的方式影响认知任务的表现和认知控制的权衡。结果显示：奖励线索只在阈上呈现时提高AX序列的任务表现; 与基线条件相比, 阈上和阈下奖励条件下认知控制的权衡均偏向主动性控制, 且这种偏向在两者间无显著差异。这表明习得的阈下奖励线索可以调节认知控制的权衡, 使被试像阈上奖励时那样偏向主动性控制。     

中国人三重自我建构加工中的相对优先性:来自ERP的证据

借助事件相关电位技术,采用启动范式的变式探讨了中国人三重自我建构的加工特点。结果发现,具体哪种自我建构占据加工优势取决于具体的加工阶段:早期加工阶段集体自我占加工优势;晚期加工阶段个体自我占加工优势;而在N2成分上,三种自我建构加工优势相当。该结果在一定程度上支持了情境性假设,拓展了三重自我建构理论的研究,为该领域的理论争论提供了新的认知神经科学证据。     

教师组织公平感与组织公民行为:工作倦怠的中介作用

采用问卷调查法,检验教师组织公平感与组织公民行为之间关系以及教师工作倦怠在二者之间的作用。通过对来自重庆和湖南郴州共32所中小学1325名教师的调查数据进行层次回归分析、中介效应检验和优势分析,结果显示:学校组织程序公平是教师组织公民行为的显著正向预测变量;教师工作倦怠是教师组织公民行为的显著负向预测变量;教师工作倦怠在教师组织公平感与其组织公民行为关系之间有显著的中介作用,其中热情枯竭和成就丧失的中介效应更为显著。
