Joseph Margolis on Pragmatism

This paper begins with a memoir of the author’s interactions with Joseph Margolis that delineates both Margolis’s importance as a teacher and their disagreements on aspects of American philosophy. It then turns to Margolis’s discussions of pragmatism as a philosophical movement, with an emphasis on his understanding of John Dewey. The paper considers, third, Margolis’s account of the decline and rebirth of pragmatism, the latter process attributed largely to the work of Richard Rorty. The paper concludes with an examination of what it sees as Margolis’s most valuable work: his explorations of the nature of the self and of human society.     

Synchrony in mother-infant vocal interactions revealed through timed event sequences

This report extends a previous cross-cultural study of synchrony in mother-infant vocal interactions (Bornstein et al., 2015) to immigrant samples. Immigrant dyads from three cultures of origin (Japan, South Korea, South America) living in the same culture of destination (the United States) were compared to nonmigrant dyads in those same cultures of origin and to nonmigrant European American dyads living in the same culture of destination (the United States). This article highlights an underutilized analysis to assess synchrony in mother-infant interaction and extends cross-cultural research on mother-infant vocal interaction. Timing of onsets and offsets of maternal speech to infants and infant nondistress vocalizations were coded separately from 50-min recorded naturalistic observations of mothers and infants. Odds ratios were computed to analyze synchrony in mother-infant vocal interactions. Synchrony was analyzed in three ways -- contingency of timed event sequences, mean differences in contingency by acculturation level and within dyads, and coordination of responsiveness within dyads. Immigrant mothers were contingently responsive to their infants’ vocalizations, but only Korean immigrant infants were contingently responsive to their mothers’ vocalizations. For the Japanese and South American comparisons, immigrant mothers were more contingently responsive than their infants (but not robustly so for South American immigrants). For the Korean comparison, mean differences in contingent responsiveness were found among acculturation groups (culture of origin, immigrant, culture of destination), but not between mothers and infants. Immigrant dyads’ mean levels of responsiveness did not differ. Immigrant mothers’ and infants’ levels of responsiveness were coordinated. Strengths and flexibility of the timed event sequential analytic approach to assessing synchrony in mother-infant interactions are discussed, particularly for culturally diverse samples.     

主观声旁家族对汉语儿童汉字命名的影响

研究选取三年级、五年级和七年级学生,采用两个汉字命名实验,考察主观声旁家族对汉字命名的影响。实验一操纵主观声旁家族大小,发现三年级儿童没有表现出家族效应;五年级儿童表现出边缘显著的家族抑制效应,即对大家族的字命名更慢;七年级儿童表现出显著的家族抑制效应。实验二操纵了目标字是否有高频家族成员字（higher frequency neighbors,HFNs）这个变量,发现儿童普遍都表现出HFNs抑制效应,即对有高频家族成员字的目标字命名更慢。以上结果表明随着年级增长,主观声旁家族对儿童命名的影响逐渐增强,且高年级儿童已表现出家族抑制效应,这一表现与普遍出现的HFNs抑制效应有关。     

儿童空间观点采择的自动性及其发展

使用空间观点采择任务,探究7~11岁儿童的空间观点采择的自动性和发展趋势。结果发现：（1）在他人任务中,正确率随着角度的增长而减小;（2）在自我任务中,相比于空间关系不一致时,一致时的正确率更高,且反向的一致性效应出现在150°~180°间。本研究结果显示：本项空间观点采择任务对儿童有效;7~9岁的儿童可以自动进行空间转换;11岁的儿童可以自动进行需要判断左右位置的空间观点采择。本研究首次证明,11岁是儿童自动进行需要判断左右位置的空间观点采择的相对年龄转折点。     

Adults' difficulties in identifying concealment among children interviewed with the putative confession instructions

The putative confession (PC) instructions (“[suspect] told me everything that happened and wants you to tell the truth”) increases children's honesty. However, research has shown that children who maintain secrecy despite the PC are more convincing. We examined whether (a) the PC undermines adults' deception detection abilities or (b) children who conceal despite the PC are better deceivers. Adults evaluated truthful and deceptive children interviewed with the PC where the PC portion of the interview was either present or absent. Adults' deception detection was no worse when the PC was present; in fact, it was slightly better. Rather than negatively affecting adults' ability to detect deception, the PC selects an unusually convincing group of concealers.     

友伴人际品格对儿童人际品格的影响:友伴数量的调节作用及儿童群体差异

友伴是儿童发展的重要影响源。本研究从儿童积极发展的视角探讨友伴人际品格（仁慈和公正）对儿童人际品格的影响及友伴数量在其中的调节作用,并检验了儿童的群体（学段、性别、是否独生）差异状况。研究采用班级同伴提名法及儿童品格调查问卷对1555名4~9年级儿童及其互提名友伴展开调查。结果发现：（1）友伴仁慈和公正显著预测所有儿童群体的仁慈和公正;（2）儿童的友伴数量更多时,友伴公正对其公正的预测作用更显著;该调节效应仅体现在初中生和男生群体上。研究结果表明,儿童与具有积极品格特征的友伴交往对其积极品格的发展至关重要,且对于特定群体（如初中生、男生）,与越多具有积极品质的友伴交往,其受到的积极影响越大。     

父母协同教养与学前儿童社会行为的关系:亲子关系和同胞关系的链式中介作用

以河南省某市四所幼儿园大、中、小班共196名学前儿童及其父母和教师为研究对象,基于家庭系统理论,采用父、母填写的父母感知协同教养量表和亲子关系量表、母亲填写的儿童早期同胞关系质量问卷和幼儿教师报告的儿童行为量表探讨亲子关系、同胞关系在父母感知协同教养与学前儿童社会行为之间的中介作用。结果发现：（1）母子冲突和母子亲密分别在母亲感知协同教养与同胞冲突和同胞温暖间起部分中介作用;父子冲突和父子亲密分别在父亲感知协同教养与同胞冲突和同胞温暖间起完全中介作用;（2）父/母子冲突和同胞冲突在母亲感知协同教养和儿童攻击行为间起链式中介作用;父子冲突和同胞冲突在父亲感知协同教养和儿童攻击行为间起链式中介作用。     

States of curiosity and interest enhance memory differently in adolescents and in children

Curiosity – broadly defined as the desire to acquire new information – enhances learning and memory in adults. In addition, interest in the information (i.e., when the information is processed) can also facilitate later memory. To date, it is not known how states of pre‐information curiosity and post‐information interest enhance memory in childhood and adolescence. We used a trivia paradigm in which children and adolescents (N = 60, 10–14 years) encoded trivia questions and answers associated with high or low curiosity. States of high pre‐answer curiosity enhanced later memory for trivia answers in both children and adolescents. However, higher positive post‐answer interest enhanced memory for trivia answers beyond the effects of curiosity more strongly in adolescents than in children. These results suggest that curiosity and interest have positive effects on learning and memory in childhood and adolescence, but might need to be harnessed in differential ways across child development to optimize learning.     

孤独症儿童动作发展障碍的神经机制

动作发展障碍(Developmental motor disorders)是孤独症谱系障碍的常见特征。通过系统回顾孤独症儿童动作发展障碍的神经科学研究, 发现γ-氨基丁酸和5-羟色胺浓度的改变及γ-氨基丁酸相关蛋白和Shank蛋白的表达异常不仅会损害中枢神经系统的发育, 而且还能导致突触兴奋性与抑制性失衡, 进而改变孤独症儿童小脑和大脑皮层运动区的功能连接。孤独症儿童小脑、基底神经节和胼胝体结构的改变对全脑的连通性产生了负面影响。神经生化机制和脑结构的异常共同导致了脑功能的异常, 最终造成孤独症儿童的动作发展障碍。此外, 动作发展障碍与孤独症核心症状共同的神经基础主要包括镜像神经元系统紊乱, 丘脑、基底神经节和小脑异常以及SLC7A5和PTEN 基因突变。未来研究需要关注与运动密切相关的其他神经递质, 如乙酰胆碱和多巴胺; 探索动作发展障碍神经网络的动态机制及其形成; 剖析该障碍的神经机制和自闭症核心症状神经机制的相互作用。     

幼儿在联合行动中共同表征能力的发展

为探究幼儿联合行动共同表征能力的发展,实验1通过比较186名3~5岁幼儿在相同任务和不同任务的表现,发现4岁和5岁幼儿在不同任务中的表现比相同任务差;实验2进一步验证幼儿在不同任务中较差的表现源于对自我和同伴的共同表征。结论：3岁幼儿无法在联合任务中同时表征自我和同伴,没有表现出明显的共同表征能力,4岁以上幼儿开始具备稳定的共同表征能力,能够在联合任务中同时表征自己和同伴,由此对自己的行为表现造成干扰。
