不同攻击/受欺负类别儿童的同伴交往自我知觉

以474名小学三、四、五、六年级的儿童为被试,考察了不同攻击-受欺负类型儿童自我知觉的社会能力以及自我提名的朋友与双向互选朋友数量、同伴积极提名、消极提名的关系。结果表明,各攻击/受欺负组别在自我提名的朋友数量上无显著差异,但在自我知觉的社会能力、双向互选朋友数及同伴积极提名、消极提名上均存在显著差异。在自我知觉的社会能力方面,单纯攻击组最高,攻击-受欺负组最低。在双向互选朋友以及同伴积极提名方面,未参与组最高,其余依次为单纯攻击组、单纯受欺负组和攻击-受欺负组。     

攻击型受欺儿童的社会行为与心理调节

本文通过对488名上海市小学四五六年级学生,采用同伴提名、教师评定、自我评定以及假设情境测验等方法,确定了攻击型受欺者,并考察了性别差异、社会行为特点、心理调节等方面。研究发现,在中国的文化背景下可以通过同伴提名的方法来确定攻击型受欺者,在性别上同样存在明显差异;攻击型受欺儿童明显具有同伴拒绝、缺乏自信心、有孤独感等社会行为特征;攻击型受欺者在社会认知上存在心理失调,表现在社会归因和应对风格上;同伴友谊是影响同伴受欺状况的重要因素。     

中小学生欺负/受欺负的普遍性与基本特点

利用修订的Olweus欺负问卷对 92 0 5名城乡儿童进行了测查 ,考察初中和小学阶段儿童欺负 /受欺负问题的普遍性及基本特点。结果发现 :中小学生中存在着较严重的欺负问题 ,近 1/ 5被调查的儿童卷入欺负 /受欺负问题 ;总体上小学和初中阶段学生欺负 /受欺负问题的发生率随年级的升高而下降 ,但欺负他人在初中阶段具有稳定性 ;直接言语欺负是最为普遍的欺负方式 ;在欺负 /受欺负的比率、对待欺负态度和欺负类型上均存在性别差异。     

从儿童赌博任务看热执行功能的发展

为考察热执行功能的发展,本研究通过儿童赌博任务检测了60名3～4岁儿童(男女各半)的情感决策。实验结果表明,3岁和4岁儿童在此任务上存在显著的年龄差异,4岁组在各试验组的分数呈上升趋势,他们在试验组2、尤其在试验组4和5中选择有利纸牌的次数显著多于3岁儿童,这反映出情感决策在3～4岁期间发展迅速。此外,儿童在此任务上的成绩存在很多可变性,可能掩盖了性别差异,因而,尽管男孩在最后两个试验组的成绩优于女孩,但性别差异在统计上并不显著。     

不同类型罪犯在爱荷华赌博任务中的决策功能缺陷

采用爱荷华赌博任务(Behcara等人1994年版本)测量了8类共222名在监男性罪犯以及32名普通男性的决策功能, 并运用前景效用学习模型分析了不同类型罪犯在情感决策中的心理功能缺陷。罪犯组选择牌1的比例与控制组没有显著差异, 选择牌2的比例显著高于控制组, 选择牌3和牌4的比例显著低于控制组。暴力犯和涉黑犯对收益和损失都不敏感, 对过去的预期效用折扣很快; 吸毒犯(已戒除)、涉毒犯、盗窃犯和抢劫犯对奖赏加工正常, 对惩罚不敏感; 经济犯选择一致性最低; 性罪犯选择一致性最高。结果表明不同类型罪犯在爱荷华赌博任务中都具有决策功能缺陷, 但他们的决策功能缺陷由不同的心理功能缺陷所致。     

受欺负对初中生主动性和反应性攻击的影响：道德推脱和性别的作用

本研究采用追踪研究设计,探讨受欺负与初中生主动性和反应性攻击之间的关系,道德推脱的中介作用以及性别的调节作用。研究对2533名八年级学生(初测年龄为13.95±0.60,51.32%男生)开展了间隔半年的两次测查。结果表明：(1)T1受欺负显著正向预测T2主动性攻击和反应性攻击;(2)T2道德推脱在T1受欺负和T2主动性、反应性攻击之间均起到部分中介作用;(3)主动性攻击的中介模型还受性别的调节,在女生中T1受欺负对T2道德推脱的预测作用更强,在男生中T2道德推脱对T2主动性攻击的预测作用更强。本研究的结果提示,相关教育工作者需要关注受欺负青少年的道德推脱水平,对这些青少年的道德认知进行有效干预,从而阻断受欺负和攻击行为之间的关联。     

奖惩对注意缺陷多动障儿童情感决策的影响

采用简化版儿童赌博任务,其中操纵了奖励和惩罚的强度,探察两种亚型(注意缺陷型和混合型)ADHD儿童的情感决策能力,同时采集儿童在任务中的皮肤电活动以探析ADHD儿童在情感决策中的生理机制.结果发现,在不同的奖惩强度下,ADHD儿童情感决策模式不同,在即刻奖励条件下,ADHD儿童情感决策的能力明显弱于正常对照组儿童,倾向于不利选择,所产生的预测性皮电振幅也明显低于正常对照组;在即刻惩罚条件下,ADHD儿童的情感决策能力未见异常.两种亚型ADHD儿童的表现模式相似.上述结果证明,ADHD儿童仅存在对奖励的异常敏感性,并确实影响了其决策能力,而其回避惩罚的能力正常.两种亚型ADHD儿童存在的问题相似.

愿望采择发展水平对幼儿情感决策的影响

选取148名4岁儿童, 运用实验法考察了幼儿的愿望采择发展水平对其情感决策的影响。结果表明: (1) 幼儿的愿望采择水平对其情感决策具有显著影响。情境中他人愿望信息充足时, 幼儿会采择他人愿望并以此为线索为他人决策, 但对线索的利用程度受其愿望采择水平的制约。(2) 在无关于他人愿望信息提示的条件下, 4岁儿童为他人与为自己的情感决策不存在显著差异。(3) 4岁儿童能够采择他人的单一愿望, 但其冲突愿望采择能力还不成熟。

Sometimes it does hurt to ask: The constructive role of articulating impressions

Decisions can sometimes have a constructive role, so that the act of, for example, choosing one option over another creates a preference for that option (e.g., , ,  and ). In this work we explore the constructive role of just articulating an impression, for a presented visual stimulus, as opposed to making a choice (specifically, the judgments we employ are affective evaluations). Using quantum probability theory, we outline a cognitive model formalizing such a constructive process. We predict a simple interaction, in relation to how a second image is evaluated, following the presentation of a first image, depending on whether there is a rating for the first image or not. The interaction predicted by the quantum model was confirmed across three experiments and a variety of control manipulations. The advantages of using quantum probability theory to model the present results, compared with existing models of sequence order effects in judgment (e.g., Hogarth & Einhorn, 1992) or other theories of constructive processes when a choice is made (e.g.,  and ) are discussed.     

Young children's affective decision-making in a gambling task: Does difficulty in learning the gain/loss schedule matter?

This research investigated the development of affective decision-making (ADM) during early childhood, in particular role of difficulty in learning a gain/loss schedule. In Experiment 1, we administrated the Children's Gambling Task (CGT) to 60 Chinese children aged 3 and 4, replicating the results obtained by Kerr and Zelazo [Kerr, A., & Zelazo, P. D. (2004). Development of “hot” executive function: The Children's Gambling Task. Brain and Cognition, 55, 148–157]. In Experiment 2, the CGT was modified to make it easier for young children to learn the gain/loss schedule by increasing delayed loss frequency and magnitude in the disadvantageous deck, and a larger sample (181 children aged 3–5) was assessed. Age-differences between 3- and 4-year-olds, rather than 4- and 5-year-olds, showed that ADM develops rapidly between 3 and 4 years. The reduction of the difficulty in learning the gain/loss schedule provides the basis for an account of the development of young children's AMD.     

Cyberbullying: Challenges and opportunities for a research program—A response to Olweus (2012)

Olweus raises some important issues, but I argue that he underestimates the impact of cyberbullying on a research programme that he has done so much to promote. Cyberbullying has a number of distinctive features that differentiate it from traditional bullying. Cyberbullying provides a new challenge to the hard core (definitional criteria separating bullying from aggression). It also provides opportunities, in terms of a broader disciplinary base, greater permeability of age and context barriers, and new theoretical possibilities.     

The developmental pathways leading to pattern recognition, joint attention, language and cognition

According to the functional/emotional hypothesis, the core capacities necessary for cognitive and language development, such as pattern recognition, joint attention, and intention reading, are downstream effects of more basic processes having to do with early patterns of affect signalling. In this paper, we present preliminary research that tests the functional/emotional hypothesis. The data set consists of profiles of the emotional functioning of infants and young children at ages 0-3, 4-5, 6-9, 10-14, 15-18, 19-24, 25-30, and 31-42 months. Data were collected on a representative population of 1640 children across the US. Results of this preliminary research point to expected correlations between the development of affective signalling and pattern recognition, joint attention, and intention reading. However, we acknowledge that this is only the first step in providing supportive evidence for the functional/emotional hypothesis. Further research is needed to establish causal connections between affective signalling and the core capacities necessary for cognitive and language development.     

公平行为的认知神经机制

大量研究采用最后通牒博弈发现人们愿意牺牲自身利益来维护公平,普遍具有不公平厌恶倾向。本文基于行为博弈任务对个体处于不同角色时的公平行为,从神经学层面做出新的解释,并对现存理论模型做了梳理。脑成像的研究发现,公平行为的相关脑区主要有负责情绪加工的脑岛和与认知控制相关的背外侧前额叶,内侧眶额皮层。前脑岛激活越大,个体拒绝不公平方案的可能性越大,而腹外侧前额叶可以调节前脑岛的活动,使个体采取更理性的方式,接受不公平分配方案。另外,睾酮素和催产素作为神经调节的激素,可以对公平行为起到调节作用,睾酮素通过抑制内侧眶额皮层的激活,增加对不公平方案的拒绝率,相反,催产素可以降低个体对于不公平方案的拒绝率,并增加个体的公平行为。
