高中生羞怯与学业适应的关系:学业求助的中介作用

本研究采用中学生羞怯量表、学业求助量表及学业适应量表对青岛两所普通中学625名高中生进行调查,分析高中生羞怯、学业求助与学业适应之间的关系,并探讨学业求助是否在高中生羞怯与学业适应之间起中介作用。结果发现:(1)羞怯可以显著预测高中生的学业适应;(2)学业求助态度在羞怯与学业适应间起部分中介作用;(3)羞怯部分通过学业求助态度经学业求助行为的多重中介作用影响学业适应。     

组织政治氛围对员工疏离感的影响：自我决定动机的中介作用

验证组织政治氛围对员工疏离感的作用,探讨自我决定动机在二者间的中介作用。研究采用一般政治行为知觉量表、工作内外动机量表和工作疏离感量表对226名企事业单位的员工进行问卷调查。研究表明,组织政治氛围对员工疏离感的个人疏离和社会疏离均具有显著的预测作用;自我决定动机在组织政治氛围与员工的个人疏离感之间起部分中介的作用,但在组织政治氛围与员工的社会疏离感之间的中介作用不显著。这说明我国员工的个人疏离感一部分来自于组织政治氛围对员自我决定动机的削弱,而社会疏离感主要来自于组织政治氛围的直接影响。     

Mothers' Ideal Positive Affect Predicts their Socialization of Children's Positive Affect

Parents generally want their children to be happy, but little is known about particular types of positive affect (PA) that parents want their children to experience. Tsai's (2007) affect valuation theory offers a useful framework to understand how parents' emotional goals may shape the socialization of particular types of PA (e.g., excitement vs. relaxation). Participants were 96 mothers and their 7- to 12-year-old children. Results indicated that mothers endorsed similar levels of ideal PA (IPA) for low-, moderate-, and high-arousal PA for both themselves and for their child, suggesting that mothers desire the same type of PA for their children as they want for themselves. In support of the study's main hypothesis, mothers' IPA for their children predicted specific socialization responses that would encourage that type of PA (e.g., mothers' high-arousal IPA predicted greater encouragement of their child to celebrate, whereas mothers' low-arousal IPA predicted encouragement of affection). The findings extend affect valuation theory and emotion socialization research by indicating that parents' emotional goals (i.e., IPA) for their children may contribute to their socialization of children's PA.     

贫困损害儿童执行功能的作用机制

贫困儿童往往表现出较差的执行功能,贫困的长期危害甚至持续到成人期。为揭示贫困与儿童执行功能弱化之间的作用机制,已有研究分别从行为、生理和脑层面开展了探索。本文沿着行为-生理-脑的内在联系与思路,系统地梳理了有关单一风险、累积风险、剥夺性风险、适应负荷以及前额叶结构和功能等内在机制的最新研究。最后提出未来研究可以关注贫困对儿童执行功能某些成分的塑造、聚焦剥夺性风险因素的作用机制、开展适应负荷生理机制和相关脑区激活的认知神经机制等方面的研究,以构建行为-生理-脑的整合框架,进一步拓展未来研究领域。     

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.

     

The Light = Healthy Intuition

This research documents a “light = healthy” intuition, such that consumers perceive foods that weigh less are healthier than their heavier counterparts with the same serving size. Subsequently, consumers consume a larger quantity of lighter-weight foods. The intuition is based on a coactivation of two meanings of the word “light”: light in physical weight and light in calorie content. An implicit attitude test finds support for this association between physical weight and food healthiness. ​Subsequently, physically lighter foods are perceived to be healthier because they are assumed to contain fewer calories. In line with the proposed coactivation mechanism, the intuition is bidirectional, where consumers also expect healthier foods to weigh less. Consequently, they discredit health claims issued for heavier foods. Finally, it was found that activating a competing intuition is effective at debiasing the “light = healthy” intuition.     

注意和记忆对孤独症儿童词汇发展滞后的影响

孤独症语言障碍的表现之一是词汇发展滞后, 可能与其注意和记忆损伤有关。当前研究结果表明, 孤独症儿童在学习词汇时难以利用社会注意提供的有效信息, 且其注意易受到无关刺激干扰, 这可能导致其形成的物体-词汇的联结不稳定, 影响其进一步将这种联结整合到心理词典并保存在记忆中。未来研究应探究联合注意影响孤独症儿童词汇学习的发展轨迹和机制, 儿童的词汇知识对其词汇记忆的影响, 并关注自然场景中孤独症儿童的词汇学习过程和个体差异。

言语记忆对视觉选择的影响:基于维度的自动注意引导

两个实验分别考察外显和内隐言语记忆中的特征维度信息对基于维度的视觉选择性注意的自动引导作用。实验一要求被试在言语工作记忆(外显言语记忆)保持阶段完成一个视觉注意任务,结果发现了显著的一致性效应,即记忆任务相关维度和注意任务相关维度不一致条件下的注意任务反应时要显著慢于两者一致条件下的反应时;实验二采用go/no-go任务以考察内隐言语记忆对视觉选择的影响,结果也发现了类似的一致性效应。这些结果表明外显和内隐言语记忆中的抽象维度信息自动引导注意选择视场中与之匹配的视觉维度,而不管该维度是否为当前注意任务的相关维度。
