对相容和不相容析取关系下析取句与条件句之间推理的比较

研究析取句和条件句之间的推理能检验推理心理学中的主要理论解释。一个实验考察了析取句和条件句中两个基本成分之间的关系(相容析取与不相容析取)和推理方向(由析取句推条件句与由条件句推析取句)对析取句与其等值的条件句之间推理的影响。结果发现,推理方向的影响取决于条件句和析取句中基本成分间的关系,在不相容析取关系下的推理成绩好于在相容析取关系下的推理成绩。现有的推理理论不能解释被试的整体反应模式,作者提出的特殊知识启发式与一般的句法意义对比启发式的竞争能统一解释被试的主导反应模式。     

消极家庭表征与青少年网络人际关系成瘾：归属感需求和社交敏感的中介作用

本研究基于情绪不安全感理论,采用问卷法对湖北省两个城市的两所中学共4476名学生进行调查,探究了消极家庭表征和青少年网络人际关系成瘾的关系,并进一步考察了归属感需求和社交敏感的链式中介作用。结果显示:(1)青少年消极家庭表征能显著正向预测其网络人际关系成瘾;(2)归属感需求和社交敏感在消极家庭表征与网络人际关系成瘾的关系中均起显著的中介作用;(3)归属感需求和社交敏感在消极家庭表征和网络人际关系成瘾的关系中起链式中介作用。本研究为开发针对性的青少年网络人际关系成瘾的预防和干预方案提供了理论基础。     

社会不平等如何影响低地位者的系统合理信念

系统合理信念反映了人们的系统支持态度,即对社会系统公正性、合理性、正当性的感知,以及相应的支持和维护社会系统的态度。以往关于社会不平等与低地位者系统合理信念的关系形成了两种对立的理论观点。一方面,社会认同理论等自利取向的理论认为,严重的不平等不利于低地位者维护自我及内群体利益,因此会损害其系统合理信念;另一方面,系统合理化理论却提出,在不平等更极端（而非平等）的社会中,人们（甚至是低地位者）反而更可能合理化不平等,表现出更高的系统合理信念。实证研究中,两种观点分别得到了一些研究的支持,但同时也面临很多质疑。 面对上述分歧,本文提出了一个整合性的解释框架,即“社会不平等影响低地位者系统合理信念的双路径模型”。该模型认为,自利取向理论与系统合理化理论其实并不矛盾,而是共同解释了不平等与低地位者系统合理信念关系的“全貌”。因此,理论争议的焦点不在于不平等究竟增强还是减弱低地位者的系统合理信念,而在于分析不平等增强或减弱低地位者系统合理信念的不同条件（即认知基础）及其内在机制（即动机基础）。 第一,在认知基础方面,不同于以往研究仅关注不平等“量”的程度及其与系统合理信念的线性关系,该模型认为还应关注不平等“质”的差异及其不同效应,即关注低地位者对不平等的认知过程。一方面,严重的不平等损害低地位者个人或群体的现实利益,构成一种现实威胁;另一方面,严重不平等的社会现状与人们关于社会系统公正性、合理性的信念相冲突,构成一种象征威胁。 第二,在动机基础方面,低地位者的自利动机与系统合理化动机分别使其反对或维护不平等现状,且两种动机彼此冲突;不同于以往研究采用对立视角考察两种动机,或是过于强调二者之一的作用;该模型认为,两种动机是并存的,相互之间并非全或无的关系。因此有必要厘清二者发挥作用的条件,即什么影响二者孰强孰弱,又是什么决定了何者发挥主导作用。 第三,区分不平等“质”的差异是厘清自利动机与系统合理化动机如何发挥作用的关键。换言之,不同动机为低地位者反对或维护不平等现状提供了动力,而何种动机发挥主导作用则取决于低地位者如何对不平等进行认知。具体而言,当凸显不平等在个体或群体水平的现实威胁时,更可能激活低地位者的自利动机（进而抑制其系统合理化动机）,继而损害其系统合理信念;而当凸显不平等在系统水平的象征威胁时,更可能激活其系统合理化动机（进而抑制其自利动机）,继而增强其系统合理信念。 “双路径模型”通过分析不平等影响低地位者系统合理信念的不同认知基础,进而厘清不同动机的作用,将以往研究中看似矛盾的结论整合于一,为理解不平等对低地位者系统合理信念的影响、解释两种理论的“分歧”提供了一种整合框架,需要未来研究进一步检验和发展。     

免费师范生职业认同感与生命意义的关系

该研究采用师范生职业认同感量表和生命态度剖面图(LAP)中的"生命意义的追寻与肯定"分量表,对258名一至三年级的免费师范生进行问卷调查,探讨免费师范生职业认同感与生命意义的关系。结果表明,免费师范生职业认同感及其各因子均与生命意义及其各因子呈显著正相关;高中低不同职业认同感组的生命意义及其各因子的组别效应显著;免费师范生职业认同感的职业效能、职业意愿与期望、职业价值三因子是生命意义的显著预测变量。     

自我损耗对工作记忆的影响及其克服

实验1考察了自我损耗对工作记忆的影响。40名6年级小学生被随机分配到实验组和控制组,分别完成损耗任务和非损耗任务。结果发现,与控制组相比,实验组被试的工作记忆容量明显降低。实验2考察积极情绪能否克服自我损耗对工作记忆的负面影响。40名6年级小学生参加了实验。在完成损耗任务后,采用自传式回忆的方法诱发实验组的积极情绪。结果发现,诱发被试的积极情绪体验,能够克服自我损耗对于工作记忆的消极影响。     

Processing biological gender and number information during Chinese pronoun resolution: ERP evidence for functional differentiation

There have been a number of behavioral and neural studies on the processing of syntactic gender and number agreement information, marked by different morpho-syntactic features during sentence comprehension. By using the event-related potential (ERP) technique, the present study investigated whether the processing of semantic gender information and the processing of notional number information can be differentiated and to what extent they might interact during Chinese pronoun resolution. The pronoun (with singular form in Experiment 1 and with plural form in Experiment 2) in a sentence matched its antecedent or mismatched it with respect to either biological gender or notional number or both. While the number mismatch elicited a P600 effect starting from 550 ms (for singular pronoun) or 400 ms (for plural pronoun) post-onset of the pronoun, the gender mismatch elicited an earlier (for singular) and larger (for both singular and plural) P600 effect. More importantly, the double mismatch produced a P600 effect identical to the effect elicited by the single gender mismatch. These results demonstrate that biological gender information and notional number information are processed differentially and have different processing priorities during Chinese pronoun resolution.     

On the automaticity of contingent capture: disruption caused by the attentional blink

Converging evidence has shown that onset capture can be completely eliminated by the demands of a concurrent task and during the attentional blink. In the present study, we investigated contingent capture during the attentional blink. We found that contingent capture was attenuated, or even completely eliminated, during the “blink” time of the attentional blink. These results indicate that contingent capture requires limited attentional resources.

Is risk-taking propensity associated with unethical behaviors? An experimental study

Are risk-takers more likely to engage in unethical behaviors? We examined the relationship between risk-taking propensity and cheating in two experimental studies. In Study 1, we examined the relationship between subjects’ risk-taking propensity and their actual self-serving dishonesty using a gambling-like task. The results suggested that risk-taking propensity, measured using a behavioral approach, was positively correlated with actual self-serving dishonest behavior. In Study 2, we measured participants’ performances using a matrices test and found that the positive correlation still held. We found that participants with high risk-taking propensity reported a lower perceived probability of being detected, which might drive their dishonest behavior.     

Estimating Latent Variable Interactions With Nonnormal Observed Data: A Comparison of Four Approaches

A Monte Carlo simulation was conducted to investigate the robustness of 4 latent variable interaction modeling approaches (Constrained Product Indicator [CPI], Generalized Appended Product Indicator [GAPI], Unconstrained Product Indicator [UPI], and Latent Moderated Structural Equations [LMS]) under high degrees of nonnormality of the observed exogenous variables. Results showed that the CPI and LMS approaches yielded biased estimates of the interaction effect when the exogenous variables were highly nonnormal. When the violation of nonnormality was not severe (normal; symmetric with excess kurtosis < 1), the LMS approach yielded the most efficient estimates of the latent interaction effect with the highest statistical power. In highly nonnormal conditions, the GAPI and UPI approaches with maximum likelihood (ML) estimation yielded unbiased latent interaction effect estimates, with acceptable actual Type I error rates for both the Wald and likelihood ratio tests of interaction effect at N ≥ 500. An empirical example illustrated the use of the 4 approaches in testing a latent variable interaction between academic self-efficacy and positive family role models in the prediction of academic performance.
