COVID-19防控的责任伦理考量

在积极应对疫情防控引发的法律及现实问题的同时,应该更加关注其责任伦理问题。如个人自由与公共责任冲突的问题,特殊从业者与职业责任冲突的问题,政府公权力的行使主体与个人知情同意的冲突问题。针对上述问题,基于责任伦理原则,提出培养个人责任伦理意识,形成群体认知共识、制定特殊人员免责条款,约束集体无意识的责任迷失、政府明确社会组织主体行使公权力的权利及限度等具体对策完善COVID-19防控机制,以保护人民的生命健康权益,促进当前及未来社会的稳定发展。

     

Ignorance May Be Bliss, But Thought Suppression Promotes Superficial Cognitive Processing

This study examined the impact of thought suppression on the quality of cognitive processing and self-reported mood. While completing a stream-of-consciousness task about two topics sequentially, participants were either instructed to suppress negative thoughts or were given no suppression instructions. Computer-based content analyses indicated that thought suppression led to significantly less causal reasoning and discrepancy seeking. However, the suppression of negative thoughts also resulted in a more positive mood. Results suggest that thought suppression can improve mood but it comes with the cognitive cost of superficial processing.     

学生学业成绩和教师控制知觉对教师差别行为的影响

采用整群抽样法,选取651名六年级小学生及其所属班级的21名班主任为被试,考察学生学业成绩和教师控制知觉对教师差别行为的影响及作用机制,探讨教师控制知觉的中介作用及其学生性别差异。结果显示:(1)女生报告获得教师更多积极行为,男生报告获得教师更多消极行为;(2)在控制了学生性别与学校地区以后,学生学业成绩仍能有效预测教师差别行为中的机会特权、情感支持和指导控制等行为,教师控制知觉能够有效预测机会特权、指导控制、情感支持和负性反馈等行为;(3)教师控制知觉在学生学业成绩与教师差别行为之间起中介作用;(4)教师控制知觉的中介模型存在学生性别差异,男生群体为完全中介作用,女生群体为部分中介作用。     

父母心理控制和儿童消极情绪性对学前儿童问题行为的共同作用:“素质-压力”还是“差别易感性”

本研究以226名学前儿童和其父母为研究对象,从儿童气质-家庭环境交互作用的视角,采用父母报告的方法收集数据,考察了父母心理控制及儿童消极情绪性对儿童问题行为的共同作用。结果发现：在预测外化问题时,父亲和母亲心理控制的主效应均显著,同时父亲心理控制与儿童消极情绪性的交互作用也显著。显著性区域分析发现,高消极情绪性的学前儿童更易受高父亲心理控制的不利影响,也更易受低父亲心理控制的有利影响,该结果支持差别易感性模型;在预测内化问题时,父亲和母亲心理控制的主效应及其与儿童消极情绪性的交互作用均不显著,说明无论是对高消极情绪性还是低消极情绪性儿童,父母心理控制对其内化问题的影响相对较弱。     

小学生近似数量系统敏锐度的发展趋势及其与数学能力的关系：抑制控制的中介作用

采用测量法和问卷法考察了172名小学生近似数量系统敏锐度的发展,以及抑制控制在近似数量系统敏锐度与数学能力关系中的中介效应。结果表明：(1)随着年龄增长,小学生的近似数量系统敏锐度逐渐提高;(2)近似数量系统敏锐度(负相关序列中的韦伯系数)和抑制控制均能显著正向预测小学生的数学能力;(3)抑制控制在小学生近似数量系统敏锐度(负相关序列中的韦伯系数)与数学能力的关系中起部分中介作用。     

自我客体化对女大学生限制性饮食行为的影响：一个有调节的中介模型

为探讨自我客体化对女大学生限制性饮食行为的影响及其内在作用机制,采用自我客体化量表、体像比较量表、限制性饮食量表和意志控制量表对487名女大学生进行调查。结果表明：（1）自我客体化、社交网站体像比较和限制性饮食两两之间均存在显著的正相关;意志控制与自我客体化、社交网站体像比较以及限制性饮食均呈显著的负相关;（2）社交网站体像比较在自我客体化对限制性饮食的影响中起中介作用;（3）自我客体化对限制性饮食影响的直接效应以及社交网站体像比较中介效应的后半路径均受到意志控制的调节,即在低意志控制群体中,这两种效应都更为显著。     

Common mechanisms of executive attention underlie executive function and effortful control in children

Executive Function (EF) and Effortful Control (EC) have traditionally been viewed as distinct constructs related to cognition and temperament during development. More recently, EF and EC have been implicated in top‐down self‐regulation ‐ the goal‐directed control of cognition, emotion, and behavior. We propose that executive attention, a limited‐capacity attentional resource subserving goal‐directed cognition and behavior, is the common cognitive mechanism underlying the self‐regulatory capacities captured by EF and EC. We addressed three related questions: (a) Do behavioral ratings of EF and EC represent the same self‐regulation construct? (b) Is this self‐regulation construct explained by a common executive attention factor as measured by performance on cognitive tasks? and (c) Does the executive attention factor explain additional variance in attention deficit hyperactivity disorder (ADHD) problems to behavioral ratings of self‐regulation? Measures of performance on complex span, general intelligence, and response inhibition tasks were obtained from 136 preadolescent children (M = 11 years, 10 months, SD = 8 months), along with self‐ and parent‐reported EC, and parent‐reported EF, and ADHD problems. Results from structural equation modeling demonstrated that behavioral ratings of EF and EC measured the same self‐regulation construct. Cognitive tasks measured a common executive attention factor that significantly explained 30% of the variance in behavioral ratings of self‐regulation. Executive attention failed to significantly explain additional variance in ADHD problems beyond that explained by behavioral ratings of self‐regulation. These findings raise questions about the utility of task‐based cognitive measures in research and clinical assessment of self‐regulation and psychopathology in developmental samples.     

冲突控制是领域一般性的还是领域特殊性的?

本研究采用整合交叉范式整合了Stroop任务和Simon任务,在双重认知控制的框架下探讨冲突控制是领域一般性的还是领域特殊性的问题。结果发现:序列一致性效应只出现在任务内,不出现于任务间,显示对冲突的反应性控制具有领域特殊性;比例一致性效应不仅出现在同种任务中,而且扩展到不同任务中,显示对冲突的主动性控制具有领域一般性。本研究结果对于理解认知控制的本质和机制具有重要意义。     

Ipsilesional Arm Aiming Movements After Stroke: Influence of the Degree of Contralesional Impairment

The authors examined the effects of the degree of impairment of the contralesional upper limb and the side of the hemispheric damage on ipsilesional upper limb performance in chronic stroke individuals. Right- and left-side stroke resulting in mild-to-severe impairment and healthy participants took part in simple and choice reaction time tasks involving aiming movements. The stroke individuals performed the aiming movements with the ipsilesional upper limb using a digitizing tablet to ipsi- or contralateral targets presented in a monitor. The global performance of the group with severe right hemispheric damage was worse than that of the other groups, indicating that the side of hemispheric damage and degree of motor impairment can adversely affect aiming movement performance.     

Inhibition difficulties in preterm children: Developmental delay or persistent deficit?

Among executive functions (EFs), research has highlighted specific inhibition difficulties in preterm children. The present paper reviews and classifies the studies that assessed response inhibition and interference control abilities in preterm children and adolescents aged 3 to 16 years. Most behavioral studies agree on a developmental delay at early school age in inhibition abilities and a catch-up before adolescence, with lesser response inhibition difficulties at pre-adolescence. However, persisting interference control difficulties have been reported into early adulthood. These results are discussed, along with functional magnetic resonance imaging (fMRI) findings. Finally, this paper outlines methodological issues that need to be overcome in order to define the developmental trajectory of inhibition abilities in the preterm population.
