Loss context enhances preferences for generosity but reduces preferences for honesty: Evidence from a combined behavioural-computational approach

The current literature has revealed mixed evidence on whether loss (vs. gain) context promotes or curtails human prosociality. The current study (N=96) aimed to address this issue by examining whether gain/loss context has distinct effects on different prosocial preferences combining computational modelling with Dictator Game and Message Game. These interactive games allow for dissociating preferences for generosity and honesty, which have been respectively associated with intuitive and deliberative systems. Our behavioural and computational modelling results indicate that loss context enhances concerns for generosity but reduces concerns for honesty. These findings support an account under the framework of dual process model asserting that loss facilitates intuitive responses during social decision-making, regardless of whether they are prosocial or proself. The current findings reconcile previous debates on the relationship between loss-gain context and human prosociality and shed light on the design of institutions to promote human prosocial behaviours.     

词素位置概率在中文阅读中的作用：词汇判断和眼动研究

中文词切分的认知机制一直是心理语言学关注的焦点问题之一,研究发现中文读者可使用词素位置概率等语言学线索帮助词切分,而首、尾词素位置概率的重要程度以往研究观点并不一致。本研究通过词汇判断和眼动实验,考察中文读者对首、尾词素位置概率的利用情况。实验1a和1b采用词汇判断任务,考察在不同词频条件下词首与词尾词素位置概率对词汇识别的影响。在错误率和反应时指标上,高频词条件下词首与词尾词素位置概率效应不显著;低频词条件下词首词素位置概率效应显著,词尾词素位置概率效应不显著。实验2a和2b采用句子阅读任务,考察在自然阅读情境中被试对词素位置概率的运用。在凝视时间、回视路径时间和总注视时间指标上,低频词条件下词首词素位置概率效应显著,词尾词素位置概率效应不显著。高频词条件下词首与词尾词素位置概率效应均不显著。词汇判断和眼动证据共同表明,词素位置概率信息是中文读者重要的语言词切分线索,且与词尾词素位置概率相比,词首词素位置概率在词汇切分与识别过程中发挥的作用更大。同时,词素位置概率线索的运用会受到词频的影响,研究结果支持复合词加工的混合通达表征模型。

Object representation and predictive action in infancy

Previous research has shown that 6‐month‐old infants extrapolate object motion on linear paths when they act predictively on fully visible moving objects but not when they observe partly occluded moving objects. The present research probed whether differences in the tasks presented to infants or in the visibility of the objects account for these findings, by investigating infants’ predictive head tracking of a visible object that moves behind a small occluder. Six‐month‐old infants were presented with an object that moved repeatedly on linear or nonlinear paths, with an occluder covering the place where all the paths intersected. The first time infants viewed an object’s motion, their head movements did not anticipate either linear or nonlinear motion, but they quickly learned to anticipate linear motion on successive trials. Infants also learned to anticipate nonlinear motion, but this learning was slower and less consistent. Learning in all cases concerned the trajectory of the object, not the specific locations at which the object appeared. These findings suggest that infants form object representations that are weakly biased toward inertial motion and that are influenced by learning. The findings accord with the thesis that a single system of representation underlies both predictive action and perception of object motion, and that occlusion reduces the precision of object representations.     

电击信号应激对大鼠体液免疫及内分泌功能的影响

研究了足电击及以电击装置为信号刺激所诱发的情绪应激对大鼠原发性体液免疫反应及内分泌的影响。 结果表明每天１０分钟,共６天的足电击对大鼠抗特异性抗原ＯＶＡ的原发性体液免疫反应无明显作用,而此电击作 用结合每天１０分钟,共８天的情绪应激则可显著降低大鼠体液免疫反应及脾脏指数。同时该应激可显著提高大鼠 血儿茶酚胶和皮质酮水平。该研究证明了情绪应激对大鼠体液免疫功能的调节作用,并对交感神经系统和下丘脑－ 垂体－肾上腺（ＨＰＡ）轴在其中所起的作用进行了初步探讨。     

一张壁虎皮

我工作的地方在太行山东麓浊漳河的北岸,村庄建在山崖之上,背靠鹰嘴岩,脚临漳河水。村前一条笔直的马路,是河南、河北、山西三省交汇地界。马路的外边,有一株千年古柏,枝繁叶茂,翠绿幽深,亭亭如盖。临河仰视,石岩古柏,云雾蒸腾,半天之上,村庄隐隐,车水马龙;倚树俯瞰,绿草如茵,漳河如黛,磐石如林,峰回路转,流水涓涓。村庄原是普通山庄,古柏给村庄带来了文化的意韵,这村庄便有了历史和来头,引来不少无病呻吟的文人墨客。2002年,上海一家采风杂志社刊登出千年古柏摇曳风姿,又配了一篇典故介绍,说古柏如何效法槐荫树,为村庄里的董永们牵线作媒;…     

《国语》名称演变探源

《国语》本为先秦时期“事语”类文献的汇编,自西汉末刘歆始视其为《春秋》之“外传”,后人又多因之,称其为《春秋外传国语》、《春秋外传》、《春秋国语》,亦有简称《外传》,或直呼为《春秋》者。目录分类上《国语》亦多入经部“春秋类”当中,直至《四库全书》方黜《国语》出经部,而入于史部“杂史类”。本文搜集诸史材料,引述前贤之论,对《国语》名称之来源、演变及其缘由略作浅析。     

道德之一元论与多元论：缘起、内涵与论争

一元论与多元论之争是道德心理学领域近些年最为活跃的理论交锋之一。道德一元论认为所有外在的道德现象与内在的道德结构都可以用一种因素来解释。道德多元论则认为道德不能只用单一因素来解释,而是存在多个不同质的道德维度,且具有文化敏感性。对应道德理论和道德基础理论是这场争议的典型代表。双方就伤害的解释力、道德失声现象、模块化道德与洁净维度独立性等方面展开论争。未来研究应从三个具体方面进一步探索道德之一元论与多元论难题,进而保持道德心理学领域的理论活力。

Investigating behavior inhibition in obsessive-compulsive disorder: Evidence from eye movements

We investigated the role of inhibition failure in Obsessive Compulsive Disorder (OCD) through an eye tracking experiment. Twenty-five subjects with OCD were recruited, as well as 25 with Generalized Anxiety Disorder (GAD) and 25 healthy controls. A 3 (group: OCD group, GAD group and control group) × 2 (target eccentricity: far and near) × 2 (saccade task: prosaccade and antisaccade) mixed design was used, with all participants completing two sets of tasks involving both prosaccade (eye movement towards a target) and antisaccade (eye movement away from a target). The main outcome was the eye movement index, including the saccade latency (the time interval from the onset of the target screen to the first saccade) and the error rate of saccade direction. The antisaccade latency and antisaccade error rates for OCDs were much higher than those for GADs and healthy controls. OCDs had longer latency and error rates for antisaccades than for prosaccades, and for far-eccentricity rather than near-eccentricity stimuli. These results suggest that OCDs experience difficulty with behavior inhibition, and that they have higher visual sensitivity to peripheral stimuli. In particular, they show greatest difficulty in inhibiting behavior directed towards peripheral stimuli.
