Counterexample Search in Diagram-Based Geometric Reasoning

Topological relations such as inside, outside, or intersection are ubiquitous to our spatial thinking. Here, we examined how people reason deductively with topological relations between points, lines, and circles in geometric diagrams. We hypothesized in particular that a counterexample search generally underlies this type of reasoning. We first verified that educated adults without specific math training were able to produce correct diagrammatic representations contained in the premisses of an inference. Our first experiment then revealed that subjects who correctly judged an inference as invalid almost always produced a counterexample to support their answer. Noticeably, even if the counterexample always bore a certain level of similarity to the initial diagram, we observed that an object was more likely to be varied between the two drawings if it was present in the conclusion of the inference. Experiments 2 and 3 then directly probed counterexample search. While participants were asked to evaluate a conclusion on the basis of a given diagram and some premisses, we modulated the difficulty of reaching a counterexample from the diagram. Our results indicate that both decreasing the counterexample density and increasing the counterexample distance impaired reasoning performance. Taken together, our results suggest that a search procedure for counterexamples, which proceeds object-wise, could underlie diagram-based geometric reasoning. Transposing points, lines, and circles to our spatial environment, the present study may ultimately provide insights on how humans reason about topological relations between positions, paths, and regions.     

父母协同教养与学前儿童社会行为的关系:亲子关系和同胞关系的链式中介作用

以河南省某市四所幼儿园大、中、小班共196名学前儿童及其父母和教师为研究对象,基于家庭系统理论,采用父、母填写的父母感知协同教养量表和亲子关系量表、母亲填写的儿童早期同胞关系质量问卷和幼儿教师报告的儿童行为量表探讨亲子关系、同胞关系在父母感知协同教养与学前儿童社会行为之间的中介作用。结果发现：（1）母子冲突和母子亲密分别在母亲感知协同教养与同胞冲突和同胞温暖间起部分中介作用;父子冲突和父子亲密分别在父亲感知协同教养与同胞冲突和同胞温暖间起完全中介作用;（2）父/母子冲突和同胞冲突在母亲感知协同教养和儿童攻击行为间起链式中介作用;父子冲突和同胞冲突在父亲感知协同教养和儿童攻击行为间起链式中介作用。     

初中生亲子关系与抑郁:自尊和情绪弹性的中介作用

基于生态系统理论和认知易感性模型,本研究拟探讨初中生亲子关系对抑郁的影响及作用机制,采用问卷法对813名初中生进行调查。结果表明：（1）亲子关系、自尊、情绪弹性与抑郁之间呈两两显著相关,且亲子关系能显著负向预测抑郁;（2）自尊和情绪弹性在亲子关系与抑郁之间起显著的中介作用,具体包括三条路径：一是自尊的单独中介作用;二是情绪弹性的单独中介作用;三是自尊和情绪弹性的序列中介作用。本研究揭示了初中生亲子关系通过内在心理因素对抑郁水平产生影响的作用机制,为进一步提升初中生的心理健康提供了指导性建议。     

Alcohol use and dating violence among college students

IntroductionNumerous studies have focused on the association of dating violence (DV) and alcohol use. However, little research has as yet assessed their co-occurrence in short timeframes.ObjectiveThis study aims to investigate alcohol use in the two hours preceding DV and in the two hours following DV.MethodCollege students (n = 649, 71% females, mean age = 19.8) reported their experience of DV and their hazardous drinking on self-administered questionnaires. They also reported their alcohol use in the two hours preceding – as well as following – a specific DV event (i.e. insult between dating partners).ResultsChi-square tests outline that alcohol use in the two hours preceding an insult is associated with alcohol use in the two hours following an insult. Regressions show that higher scores of hazardous drinking puts students at risk of insulting or being insulted in a context of alcohol use.ConclusionThe findings can contribute to DV prevention programs among college students.     

亲子间科技干扰与青少年网络人际关系成瘾：有调节的中介模型

对1353名高中生进行问卷调查,探究亲子间科技干扰与青少年网络人际关系成瘾之间的关系,相对剥夺感的中介作用及内在觉知的调节作用,结果表明：（1）亲子间科技干扰正向预测青少年网络人际关系成瘾;（2）相对剥夺感是亲子间科技干扰与网络人际关系成瘾之间的中介变量;（3）亲子间科技干扰与网络人际关系成瘾的间接效应前半段受到内在觉知的调节。因此,亲子间科技干扰和网络人际关系成瘾之间存在有调节的中介效应。     

Exposure to intergroup conspiracy theories promotes prejudice which spreads across groups

This research experimentally examined the effects of exposure to intergroup conspiracy theories on prejudice and discrimination. Study 1 (N = 166) demonstrated that exposure to conspiracy theories concerning immigrants to Britain from the European Union (vs. anti-conspiracy material or a control) exacerbated prejudice towards this group. Study 2 (N = 173) found the same effect in a different intergroup context – exposure to conspiracy theories about Jewish people (vs. anti-conspiracy material or a control) increased prejudice towards this group and reduced participants’ willingness to vote for a Jewish political candidate. Finally, Study 3 (N = 114) demonstrated that exposure to conspiracy theories about Jewish people not only increased prejudice towards this group but was indirectly associated with increased prejudice towards a number of secondary outgroups (e.g., Asians, Arabs, Americans, Irish, Australians). The current research suggests that conspiracy theories may have potentially damaging and widespread consequences for intergroup relations.     

Between Literature and Psychology: Konishi Masutaro (1862–1940) in the History of Russo–Japanese Scientific Connections

The aim of this paper is to describe some episodes from the life of Konishi Masutaro (1862–1940), a Japanese scholar and psychologist who obtained his theological and psychological education in Russia and who played a role in the development of psychological science in Russia. Masutaro is mostly known as a translator of Lev (Leo) Tolstoy, and the psychological side of his biography is not well studied. Masutaro's life and work in Russia occurred in the context of great political and cultural changes. He was one of the first authors who translated fragments from Eastern philosophy (works by Laozi and Confucius) into the Russian language. Personal and scientific details of the life of this educated scholar are also given in the present paper.     

Inherited and Environmental Moderators of Mother-Child Behavioral Contingency and Contingent Negativity at 27 Months

Previous research has shown that as depressive symptomology increases, mothers tend to show withdrawn or harsh interaction patterns with their children, and the quality of these interaction patterns have subsequently been linked to child behavior problems. However, little research has examined bidirectional influences between mothers and their children, and how these moment-to-moment contingencies differ based on heritable and environmental characteristics. We used data from the Early Growth and Development Study a prospective adoption study to examine how adoptive mothers’ depressive symptoms and children’s heritable tendencies for negative affectivity interact to predict the quality of mother-child interactions at child age 27-months. Results detected two distinct dyadic interaction patterns. The first was a withdrawn interaction style and was observed in children with a high heritable tendency for negative affect. In that style, mother and child interactions were not contingent upon each other, suggesting a lack of joint engagement. The second was a volatile interaction style, observed in children with a low heritable tendency for negative affect. In these cases, mother and child interactions were highly contingent but negative. Our findings demonstrate essential differences in how dyadic interaction patterns vary according to level of depressive symptomology and heritable tendency for negative affect.     

Predictors of Client Attrition in a University-Based Community Counseling Clinic

The purpose of this study was to investigate how symptom distress, social role, interpersonal relationships, gender, age, number of supports, and education level predict client attrition in a community sample. Using binary logistic regression and cross-sectional data, the authors examined the predictive impact of 8 variables on adult client attrition in a university-based community counseling clinic. Results indicated that education level, interpersonal relationships, and number of supports significantly predicted attrition. In this sample, gender, age, symptom distress, social role, and race did not significantly predict attrition. Implications for clinical assessment and counseling practice are discussed.
