反应抑制的训练:内容、效果与机制

近期的研究发现,个体的反应抑制能力具有一定的可塑性。研究者多采用双盲随机对照实验设计,训练的对象包括儿童、成人和特殊群体,研究者通过Go/Nogo、Stop-signal等任务进行为期1周至3周,45至7200试次不等的抑制控制能力训练,并结合行为、脑电以及脑成像等技术对训练效果进行评估,研究结果发现,接受了抑制控制训练的个体其抑制能力得到提升,并伴随脑神经活动的变化。另外,研究者发现,抑制控制能力的训练效果还可以迁移至个体日常生活中的表现。但是,也有些研究并未发现抑制控制训练的效果。训练任务的设置,评估任务的选择以及被试反应策略的差异等因素可能会影响训练的效果。抑制控制训练引发行为与大脑活动的变化可能是由于训练导致了个体建立了自上而下有意识的抑制控制模式和自下而上的自动抑制模式。反应抑制和冲突抑制可塑性的比较,儿童与老年人抑制功能的训练以及训练效果的追踪研究将成为该领域日后研究的重点问题。     

熟悉性和兼容性对复合社会范畴刻板印象表征的影响

通过对启动任务范式的改进,运用3个实验全面考察了复合社会范畴本身的熟悉性和兼容性对复合社会范畴刻板印象中抽象表征和样例表征策略运用的影响。实验1分别以熟悉的、不熟悉且在刻板印象上不兼容的复合范畴为研究对象,研究发现对熟悉的复合范畴采用抽象表征,而对不熟悉且在刻板印象上不兼容的复合范畴的表征采用样例表征;实验2以熟悉且在刻板印象上不兼容的复合范畴为研究对象,研究发现对于熟悉但构成范畴不兼容的复合范畴的表征也采用样例表征;实验3采用相同的实验范式,在描述和定义两种启动任务中设置子范畴间兼容的刻板特质词和不兼容的刻板特质词,选择与实验2相同的复合范畴"男中学教师"为目标群体,更加严密地证实和整合了实验1与实验2的研究结论。3个实验的结果说明复合范畴刻板印象的表征关键取决于兼容性,一旦复合社会范畴的构成范畴在刻板印象上不兼容,那么对于这一复合社会范畴刻板印象的表征采用样例表征。当构成复合范畴的两个子范畴之间兼容时,熟悉性成为刻板印象运用抽象表征还是样例表征的影响因素,无论是对内群体的刻板印象还是外群体的刻板印象,对熟悉的刻板特质词的表征运用抽象表征。     

The Relationship Between Racial Identity Status Attitudes and Acculturation Among Chinese and Korean Americans: A Criterion Profile Analysis

This study tested the relationship between racial identity and acculturation among 223 Asian Americans self‐identifying as Chinese American or Korean American. Findings showed within‐group variations among the study participants with regard to their racial identity status attitudes and acculturation. Using criterion profile analysis, the authors found 2 distinctive criterion profiles of racial identity status attitudes that significantly related to higher levels of acculturation among Chinese American and Korean American participants. Implications for multicultural counseling, racial identity, and acculturation research are discussed. Este estudio puso a prueba la relación entre identidad racial y aculturación entre 223 individuos asiático‐americanos que se identifican a sí mismos como chino‐americanos o coreano‐americanos. Los resultados mostraron variaciones dentro del miso grupo entre los participantes del estudio en cuanto a su aculturación y sus actitudes hacia el estatus de su identidad racial. Usando un análisis de perfil de criterio, los autores encontraron 2 perfiles de criterio distintivos para las actitudes hacia el estatus de identidad racial que estaban relacionados significativamente con niveles más altos de aculturación entre los participantes chino‐americanos y coreano‐americanos. Se discuten las implicaciones para investigaciones sobre consejería multicultural, identidad racial y aculturación.     

全球生命伦理学

探讨生命伦理学的起源,并阐述了不同理论支持者的观点,发现无论准确的生命伦理学历史起源是什么,目前生命伦理学已经变成了一种真正的全球现象。它在全世界具有重要的意义,因为人类不仅仅是欧洲人或亚洲人,也是世界公民和一个全球道德共同体的成员。生命伦理学对任何地方、任何人都是重要的,并不是因为它是"拿来"的,而是因为它提供了一个普遍的框架去解释和管理正在经历的变化,这个变化包括了目前所有的国家和文化。然而,这个框架的解释和应用必须依据本土环境。因此,现代生命伦理学具有全球性和本土特征的特点。     

论对精神障碍患者的医学保护性住院治疗——评《精神卫生法》第三十一条

《精神卫生法》将强制住院类型分为医学保护性住院和保安性住院。针对严重精神病患者,若已经发生伤害自身的行为或有伤害自身的危险,可以对其实施医学保护性住院治疗,但其具有限制人身自由的属性。而《精神卫生法》第三十一条却将医学保护性住院治疗的同意权单独授予监护人,患者出院也需要监护人的同意。此规定缺乏正当性,侵害了患者的正当权利。而这一规定存在的原因有多种,如医疗父权主义思想的影响,将精神障碍当然地视为无民事行为能力等。     

Burger or yogurt? Indulgent consumption in impression management contexts

We conducted three studies to investigate indulgent choice in settings with and without impression management by public–private manipulation with evaluation. Study 1 showed that the participants were less indulgent under public scrutiny due to the employment of impression management. Study 2 focused on the impression management context to test the moderate effect of self‐consciousness in two impression managed contexts. Study 3 focused on context without impression management to test the moderate effects of self‐awareness on choices. We found that depending on differences in primed personality, individuals tended to make choices other than those they favoured privately when anticipating that others might form impressions of them based on the decisions made. The findings of all three studies support our basic prediction that people are less indulgent under impression management and suggest that people tend to manage their impression by eating healthier (less indulgently) in public.

Factors Moderating Children's Adjustment to Parental Separation: Findings From a Community Study in England

Research findings show that there is marked variability in children's response to parental separation, but few studies identify the sources of this variation. This prospective longitudinal study examines the factors modifying children's adjustment to parental separation in a community sample of 5,635 families in England. Children's behavioral/emotional problems were assessed when children were aged 47 and 81 months; marital quality, maternal depression, socioeconomic circumstances, and demographic variables were assessed prior to the separation from maternal report. Results indicated that 346 mothers separated from their partners in the 3-year period. Preseparation differences were found for measures of family process and parent risk factors, with effect sizes ranging from small to trivial. Parental separation was associated with a significant but modest increase in behavioral/emotional problems, independent of marital quality, maternal depression, socioeconomic circumstances, and demographic variables. Moderation analyses showed that children of cohabiting parents had a greater increase in adjustment problems following parental separation than children of married parents. Further research elucidating the factors that moderate children's adjustment to parental separation is needed to improve our understanding of who may most likely benefit from preventive interventions.     

Gaze allocation in a dynamic situation: effects of social status and speaking

Human visual attention operates in a context that is complex, social and dynamic. To explore this, we recorded people taking part in a group decision-making task and then showed video clips of these situations to new participants while tracking their eye movements. Observers spent the majority of time looking at the people in the videos, and in particular at their eyes and faces. The social status of the people in the clips had been rated by their peers in the group task, and this status hierarchy strongly predicted where eye-tracker participants looked: high-status individuals were gazed at much more often, and for longer, than low-status individuals, even over short, 20-s videos. Fixation was temporally coupled to the person who was talking at any one time, but this did not account for the effect of social status on attention. These results are consistent with a gaze system that is attuned to the presence of other individuals, to their social status within a group, and to the information most useful for social interaction.
