相干逻辑的情境论解释

相干逻辑的情境论解释属于相干逻辑的直观语义。情境论以集合论的方式处理信息,用＂邻界＂的概念拓宽了可能世界语义学。情境论不仅以直观的方式解释了相干逻辑,还在相干逻辑如何解决蕴涵怪论,如何进一步修正逻辑上具有重要作用,理当受到现代逻辑学家更多的关注。     

Strategic and automatic effects of visual working memory on attention in visual search

Previous research indicates that visual attention can be automatically captured by sensory inputs that match the contents of visual working memory. However, Woodman and Luck (2007) showed that information in working memory can be used flexibly as a template for either selection or rejection according to task demands. We report two experiments that extend their work. Participants performed a visual search task while maintaining items in visual working memory. Memory items were presented for either a short or long exposure duration immediately prior to the search task. Memory was tested by a change-detection task immediately afterwards. On a random half of trials items in memory matched either one distractor in the search task (Experiment 1) or three (Experiment 2). The main result was that matching distractors speeded or slowed target detection depending on whether memory items were presented for a long or short duration. These effects were more in evidence with three matching distractors than one. We conclude that the influence of visual working memory on visual search is indeed flexible but is not solely a function of task demands. Our results suggest that attentional capture by perceptual inputs matching information in visual working memory involves a fast automatic process that can be overridden by a slower top-down process of attentional avoidance.     

Scientists’ Argumentative Reasoning

Reasoning, defined as the production and evaluation of reasons, is a central process in science. The dominant view of reasoning, both in the psychology of reasoning and in the psychology of science, is of a mechanism with an asocial function: bettering the beliefs of the lone reasoner. Many observations, however, are difficult to reconcile with this view of reasoning; in particular, reasoning systematically searches for reasons that support the reasoner’s initial beliefs, and it only evaluates these reasons cursorily. By contrast, reasoners are well able to evaluate others’ reasons: accepting strong arguments and rejecting weak ones. The argumentative theory of reasoning accounts for these traits of reasoning by postulating that the evolved function of reasoning is to argue: to find arguments to convince others and to change one’s mind when confronted with good arguments. Scientific reasoning, however, is often described as being at odds with such an argumentative mechanisms: scientists are supposed to reason objectively on their own, and to be pigheaded when their theories are challenged, even by good arguments. In this article, we review evidence showing that scientists, when reasoning, are subject to the same biases as are lay people while being able to change their mind when confronted with good arguments. We conclude that the argumentative theory of reasoning explains well key features of scientists’ reasoning and that differences in the way scientists and laypeople reason result from the institutional framework of science.     

Feeling Better About Self After Receiving Negative Feedback: When the Sense That Ability Can Be Improved Is Activated

Past studies suggest that managers and educators often consider negative feedback as a motivator for individuals to think about their shortcomings and improve their work, but delivering negative feedback does not always achieve desired results. The present study, based on incremental theory, employed an intervention method to activate the belief that a particular ability could be improved after negative feedback. Three experiments tested the intervention effect on negative self-relevant emotion. Study 1 indicated conveying suggestions for improving ability reduced negative self-relevant emotion after negative feedback. Study 2 tested whether activating the sense of possible improvement in the ability could reduce negative self-relevant emotion. Results indicated activating the belief that ability could be improved reduced negative self-relevant emotion after failure, but delivering emotion management information alone did not yield the same effect. Study 3 extended the results by affirming the effort participants made in doing the test, and found the affirmation reduced negative self-relevant emotion. Collectively, the findings indicated focusing on the belief that the ability could be improved in the future can reduce negative self-relevant emotion after negative feedback.     

Dyadic Cross-Sectional Associations Between Negative Mood,Marital Idealization,and Relationship Quality

This study aimed to evaluate (a) dyadic associations between relationship quality (RQ) and both depressive and anxious mood (DM and AM), (b) reciprocity hypotheses of negative mood within dyadic interactions, and (c) mediational role of marital idealization between negative mood and relationship quality. Actor-partner interdependence models (APIMs) were performed using data from a sample of 198 dyads. Our results showed that (a) these two facets of negative mood did not have the same weight on RQ and that they had a gender-specific effects pattern, and (b) there was no support for the mood transmission hypothesis. Men's DM displayed direct and indirect (via marital idealization) actor as well as partner effects on RQ, whereas women's DM displayed only a direct actor effect on RQ. There were no significant direct actor effects of AM on RQ, meaning that this link is fully mediated by marital idealization. However, only women's AM showed such indirect effects on RQ.     

情绪效价的记忆增强效应:存储或提取优势?

情绪效价和情绪唤醒是描述情绪的两个维度。情绪增强记忆效应表明情绪唤醒事件的记忆往往优于非情绪唤醒事件的记忆,但关于积极情绪记忆和消极情绪记忆哪个在记忆中处于优势仍存在争论。实验以情绪词对和中性词对为实验材料。实验一探讨积极情绪词语或消极情绪词语的记忆优势; 实验二探讨积极情绪环境或消极情绪环境中中性词语的记忆优势。在两种实验条件下,积极情绪下的自由回忆都优于消极情绪下的自由回忆; 多项加工树的存储—提取模型使用实验自由回忆和线索回忆的结果将记忆的存储和提取优势分离开来,结果表明:积极情绪事件记忆优势发生在存储阶段,而积极情绪环境记忆优势发生在存储和提取阶段; 积极情绪事件记忆偏向支持“刺激后编码增强假设”,积极情绪环境记忆偏向支持“唤醒—偏向竞争假设”。     

Psychiatric Distress and Suicidal Tendencies in Adult Cancer Survivors: Verifying the Validity of the Brief Symptom Inventory-18 for Identifying Suicidal Ideation in the Hospitalized Population of Mainland China

The Brief Symptom Inventory-18 (BSI-18) is widely used to assess psychiatric distress but has not been verified in the Chinese population. From March to April 2019, 293 hospitalized cancer patients, aged 20–87, completed the cross-sectional survey with demographics questionnaire, BSI-18, and PHQ-9. We analyzed the single suicide-related item of PHQ-9 with the full score clinical outpoint for BSI-18 and PHQ-9 using SPSS 22.0 and R 2.15, including Pearson's χ² test and ROC curve analyses. A Pearson's χ² test was carried out to compare the three different methods with the gold screening criteria. The p-value was correspondingly to .006, .066, .838. When the PHQ-9?≥?10 criteria for the BSI-18, receiver operating characteristic analysis revealed that AUC values were 0.839, optimal cut-off points for both BSI-18?≥?50, the sensitivity of 85.8%, and 62.5%, respectively. The BSI-18 is suitable for a screening tool for psychological distress and could also be used in clinical settings for preliminary screening of hospitalized cancer patients.

     

几何图形类比推理的ERP研究

该研究以几何图形作为实验材料,测定14名硕士研究生在完成两种类比推理任务（大小变化和颜色变化）和其基线任务时的事件相关电位（ERP）,探讨类比推理过程的脑内时程动态变化。研究发现,两种推理任务所诱发的波形基本一致,而推理任务与其基线任务之间的ERP波形存在显著差异,两种基线任务之间的ERP波形也存在显著差异;类比推理的加工过程是有阶段性的,即编码潍断、映射、得出结论,研究结果进一步支持了Sternberg的成分理论;推断和映射这两个类比推理所特有的加工阶段都有其对应的脑机制,图式推断阶段主要激活的是前额皮层和双侧的顶叶皮层,类比映射和调整阶段主要激活的是左半球的颞叶、额叶和中央顶。
