Are humans rational? Exploring factors influencing impulse buying intention and continuous impulse buying intention

This study investigates the effects of consumers' impulsivity traits, option framing, product type, and cash refund promotion on consumers' online impulse buying intention. This study follows two stages to investigate factors influencing impulse buying intention and continuous impulse buying intention. In Stage 1, this study investigates the influence of impulsivity traits (high/low), option framing (+OF/−OF), and product type (hedonic product/utilitarian product) in online shopping on impulse buying intention. In Stage 2, this study explores factors moderating the continuous impulse buying intention. Cash refund promotion (high/low) serves as the moderator. The experiment results demonstrated that subjects with high impulsivity traits, “subtractive option framing (−OF), and hedonic products” are more likely to engage in impulse buying intention. In addition, cash refund promotion at a higher level increases consumers' continuous impulse buying intention. The findings provide guidance for designing appropriate online promotion situation to induce consumers' impulse buying intention that favors online retailers.

情绪对职业价值观的影响——意义建构的中介作用

为了考察情绪对于职业价值观的影响,本研究采用情绪量表、意义建构量表、职业价值观量表以及社交媒体依赖程度量表等,对938名员工数据进行检验,结果表明:(1)情绪对于职业价值观具有显著的正向影响;(2)意义建构在情绪与职业价值观之间起完全中介作用;(3)社交媒体依赖程度负向调节了情感与意义建构之间的关系。情绪通过意义建构的中介作用对职业价值观产生影响,并且社交依赖在路径的前半段起调节作用。探究情绪与职业价值观关系,对于科学树立合理的职业价值观具有重要意义。     

Out of mind,out of sight? Investigating abnormal face scanning in autism spectrum disorder using gaze‐contingent paradigm

Diminished social motivation is hypothesized to explain abnormal face scanning pattern in individuals with autism spectrum disorder (ASD), especially reduced eye‐looking time in ASDs than typically developing (TD) people. Here, we tested an alternative explanation that children with ASD may use a compensatory strategy to avoid direct eye contact by processing the eyes through peripheral vision. We compared the face scanning patterns of children with and without ASD in two conditions: in the clear condition, the face was completely visible; in the blur condition, by using the gaze‐contingent paradigm, the whole face was blurred except for a small region being fixated at, thus children could not rely on the peripheral information to process the eyes. We found that children with ASD fixated less on the eyes than TD children in both conditions. Temporal‐course analyses further revealed the possible motivation‐based guidance of attention to process the eyes in the TD group but not in the ASD group. Additionally, we found that children with ASD scanned faces more randomly and less strategically than TD children. These results have ruled out the alternative hypothesis that the abnormal face scanning pattern in ASDs was due to their compensatory strategy to process eyes through peripheral vision, furthering our understanding of the mechanisms underlying their abnormal face scanning.     

基于脑结构像的精神分裂症机器学习分类

将机器学习应用于精神疾患的临床和基础研究是近年来的趋势。研究者将机器学习应用于精神分裂症患者及高危人群的T1加权像和弥散张量成像的脑影像数据中, 为了解疾病的生理病理学机制提供帮助。回顾以往研究发现额叶及颞叶的脑结构特征具有较高的区分能力, 行为数据和脑影像数据结合的分类效果优于单模态数据。现阶段研究存在样本量不足和泛化能力欠缺的局限, 未来研究应注意扩大样本量、制定标准化的分类方法, 从而进一步探究机器学习在精神疾患中的作用。     

Racial Colorblindness and Confidence in and Likelihood of Action to Address Prejudice

In this study, we examined the association between racial colorblindness and inaction to address prejudice. Conceptualized as a type of legitimizing ideology that maintains societal inequality, we hypothesized that colorblindness would be associated with less confidence in and lower likelihood of engaging in action to address prejudice. Our study examined the role of affective variables in explaining the link between colorblindness and inaction, as well as explored potential racial group differences. We used multigroup structural equation modeling analysis to test for measurement and structural invariance of our hypothesized model across White, Asian American, and Underrepresented racial minority (i.e., African American, Latinx American, Hawaiian/Pacific Islander, Native American, and Multiracial students from Underrepresented groups) college students. In Study 1 (n = 1,125), we found that greater colorblindness was indirectly associated with less confidence in action through affective variables (e.g., intergroup empathy, and positive and negative emotions during intergroup interactions). In Study 2 (n = 1,356), we found that greater colorblindness was indirectly related to less likelihood of action through intergroup empathy. In both studies, we demonstrated measurement and structural invariance across racial groups, indicating that our hypothesized model functioned similarly across White, Underrepresented, and Asian American students. Our findings have implications for future research and practice to challenge colorblindness and to promote engagement in actions to reduce prejudice.     

期望与绩效的关系:调节定向的调节作用

经典动机理论认为高期望能提高绩效水平,本研究结合调节定向理论进一步回答这种效应"何时"存在或"如何"产生的问题。研究1通过测量期望水平、并用任务框架操作调节定向,检验了情景启动的调节定向对期望与行为间关系的影响;研究2采取更严格的被试内设计通过任务难度操作期望,考察了作为个体长期差异的调节定向的作用。结果表明:①调节定向调节成功期望与绩效之间的关系:对于促进定向,成功期望与绩效正相关;对于预防定向,期望与绩效相关不显著。②动机可以部分解释调节定向与期望的交互作用机制:高水平的成功期望会提高促进定向个体的动机强度,进而产生高的绩效结果;其对预防定向个体的动机强度的影响不显著。     

抑郁症患者的自传体记忆特征及其应用自传体记忆测验的元分析

研究目的在于探讨抑郁症患者自传体记忆的特征以及自传体记忆测验(the autobiographical memory test, AMT)在该领域的应用情况。通过文献检索, 搜集了18篇应用AMT作为测评工具的抑郁症自传体记忆研究, 抑郁症患者566人, 正常对照组457人。元分析研究发现, 和正常对照组比较, 抑郁症组的具体性记忆减少, 概括化记忆增多, 反应迟缓。目前对这种现象的解释主要有功能性回避模型、认知执行受损模型和沉思模型; 年龄、抑郁情绪以及AMT测试程序对测试结果有明显影响; 发表偏倚和敏感性分析显示存在发表偏倚, 但稳定性较好。AMT在抑郁症研究存在灵敏度不足等局限, 作者从AMT程序、研究设计等方面提出了改善建议。     

对话：医学人人文中的普世关怀与公共理性

对话主张,我们不妨暂时放弃最高限度的理想化方式（终极关怀）,转而寻求宽容、宽泛前提下的公共理性,医学不仅是科学的,更是人文的。而要推动技术教育至上背景下生长的一代青年学子完成这样一次沉重的转向,有两门学科不可绕过,一门是科学史,另一门是科学哲学。     

不同类别学习方式的对比研究

55名被试被随机分配到两个组,分别通过分类学习与推理学习来学习两个类别,之后,两组被试对新的测试项目进行典型性评定,考察类别学习方式对类别表征的影响。研究结果表明,分类学习者仅仅依据项目的诊断性程度来评定,而推理学习者主要依据项目的典型性程度来评定。所以,诊断性信息在分类学习者的类别表征中占有重要位置,典型性信息在推理学习者的类别表征中占有重要位置,即分类学习与推理学习导致的类别表征不同。
