Development of Recognition of Face Parts from Unfamiliar Faces

The present study examined developmental changes in the ability to recognize face parts. In Experiment 1, participants were familiarized with whole faces and given a recognition test with old and new eyes, noses, mouths, inner faces, outer faces, or whole faces. Adults were above chance in their recognition of the eye and mouth regions. However, children did not naturally encode and recognize face parts independently of the entire face. In addition, all age groups showed comparable inner and outer face recognition, except for 8‐ to 9‐year‐olds who showed a recognition advantage for outer faces. In Experiment 2, when participants were familiarized with eyes, noses, or mouths and tested with eyes, noses, or mouths, respectively, all ages showed above‐chance recognition of eyes and mouths. Thirteen‐ to 14‐year‐olds were adult‐like in their recognition of the eye region, but mouth recognition continued to develop beyond 14 years of age. Nose recognition was above chance among 13‐ to 14‐year‐olds, but recognition scores remained low even in adulthood. The present findings reveal unique developmental trajectories in the use of isolated facial regions in face recognition and suggest that featural cues (as a class) have a different ontogenetic course relative to holistic and configural cues.

情绪加工老龄化机制：表情的自动加工和控制加工视角

情绪加工老龄化已经成为老龄化研究的新热点, 但其内在机制仍然缺乏统一的解释。本研究以自动加工和控制加工为切入点, 综合行为实验、ERP和fMRI实验技术, 开展表情加工的老龄化研究, 从情绪与认知交互的角度进一步揭示情绪加工老龄化的内在机制。具体内容包括表情自动加工和控制加工的年龄差异及其神经机制, 表情自动加工与认知控制的相互作用, 以及个体差异在情绪加工老龄化中的作用等。本研究将加深对情绪加工老龄化的理解, 为相关理论模型的验证、修正和完善提供实证依据。     

The Detection of Prosocial Lying by Children

The purpose of the present study was to explore the detection of prosocial lying in children. Six‐ to 11‐year‐olds and adults were videotaped telling the truth or a lie about the desirability of an object, sometimes being asked a follow‐up question (i.e., elaborative trials) and other times not (i.e., regular trials). A different group of adults and children then judged the veracity of the individuals' statements in the video clips. Adults and children performed significantly better than chance at detecting lies in the youngest age group, and children's detection performance was unrelated to their age. Child lie detectors, unlike the adults, were also able to discriminate between adults' truthful and untruthful statements in the regular trials, but misidentified adults' truthful responses as lies. They appeared to be more trusting of other children. Copyright © 2016 John Wiley & Sons, Ltd.     

视觉长时记忆激活度对促进视觉短时记忆的影响

短时记忆与长时记忆的关系是记忆领域研究的重要内容。基于此, 研究者们就视觉长时记忆是否能促进视觉短时记忆的问题展开了大量研究, 但所得出的结论并不一致。通过不同程度的学习形成不同激活度的视觉长时记忆, 考察对几何图形的视觉长时记忆是否能对变化检测中的短时记忆起到促进作用。结果发现, 低激活水平的视觉长时记忆不能促进视觉短时记忆, 而事先存在且高度激活的视觉长时记忆对视觉短时记忆却具有促进作用; 同时, 随着视觉长时记忆激活水平的提高, 刺激间间隔的效应值也逐渐减小。本研究说明, 视觉长时记忆能否促进视觉短时记忆取决于视觉长时记忆的激活水平, 高激活的视觉长时记忆对阻止视觉短时记忆痕迹的迅速消退具有重要意义。     

Evaluation of the rate of problem behavior maintained by different reinforcers across preference assessments

The rates of problem behavior maintained by different reinforcers were evaluated across 3 preference assessment formats (i.e., paired stimulus, multiple-stimulus without replacement, and free operant). The experimenter administered each assessment format 5 times in a random order for 7 children with developmental disabilities whose problem behavior was maintained by attention, tangible items, or escape. Results demonstrated different effects related to the occurrence of problem behavior, suggesting an interaction between function of problem behavior and assessment format. Implications for practitioners are discussed with respect to assessing preferences of individuals with developmental disabilities who exhibit problem behavior.     

DRD2基因TaqIA多态性与同伴侵害对青少年早期抑郁的交互作用

本研究运用问卷法与DNA分型技术,对1063名青少年(初次测评年龄为12.32±0.47岁,50.3%女生)进行间隔2年的追踪调查,考察DRD2基因TaqIA多态性与同伴身体侵害和关系侵害对青少年早期抑郁的交互作用及其性别差异。结果发现,TaqIA多态性与身体侵害、关系侵害均对男青少年抑郁存在显著的交互作用。在携带A2A2基因型的男生中,身体侵害和关系侵害可以显著正向预测其抑郁水平,而在携带A1等位基因的男生中,同伴侵害对抑郁无预测作用。此外,TaqIA多态性与身体侵害、关系侵害对女生抑郁均无显著交互作用。研究结果提示,同伴侵害是一种重要的候选环境指标,与TaqIA多态性交互影响青少年早期抑郁,并且性别在这一基因×环境交互作用中起到重要的调节效应。     

MAOA基因rs6323多态性与同伴关系对男青少年早期抑郁的影响

以683名男青少年为被试(初次测评时M = 13.35岁; SD = 0.51), 综合运用传统回归分析和新兴显著性区域检验, 考察了MAOA基因rs6323多态性与同伴关系对青少年早期抑郁的交互作用及其表现形式。结果表明：当同伴接纳水平较低时, G等位基因携带者的抑郁水平表现出高于T等位基因携带者的趋势, 当同伴接纳水平较高时, G型基因携带者的抑郁水平显著低于T等位基因携带者; 同伴接纳可以显著预测G等位基因携带者的抑郁, 但对T等位基因携带者的抑郁无显著预测作用; rs6323多态性与同伴拒绝的交互作用亦不显著。研究结果提示, 同伴关系对MAOA基因与男青少年早期抑郁的关联起调节作用, 且其作用形式部分支持不同易感性模型观点。     

货币·金融危机·新自由主义——关于现代化与当代资本主义的访谈

The current global financial crisis is essentially a credit crisis of currencies. The divorce of the U.S. dollar from Gold Specie Standard makes its issuance under the control of the U.S. government and even risk losing control. When the U.S. dollar becomes the world currency,the U.S government would be able to influence and even control the central banks of other countries through issuing U.S. dollars. However,it may also lead to the credit crisis if there is no sufficient wealth to establish a solid found...     

小学语文教学中改善学生情绪调节困难状况的实验研究

采用实验组、控制组前后测实验设计,选取42名小学四年级学生,以语文学科教学为依托,运用教学实验方法探索语文教学中改善学生情绪调节困难状况之渗透方式的有效性。结果表明:学科渗透可以在一定程度上改善学生情绪调节困难状况、促进心理素质发展,特别是对中、高程度情绪调节困难学生的改善更为显著;实验组语文学业成绩比控制组有所提高,但并未达到显著性水平。说明学科渗透可以作为学生心理素质教育实施的有效途径之一。     

流动儿童的未来取向及与学业卷入的关系

采用问卷法,选取755名初中生(其中流动儿童562名)作为被试,对未来取向及其与学业卷入的关系进行考察。结果表明:(1)打工子弟学校流动儿童的未来取向与公立学校流动儿童、城市儿童差异较大,具体表现为,打工子弟学校流动儿童的受教育领域未来目标显著较少,未来职业目标较多;未来计划得分显著较低;未来评价方面,打工子弟学校的流动儿童具有较少的内部归因,乐观性也较弱;(2)打工子弟学校的流动儿童未来取向主要表现出了年级差异,初一年级受教育目标显著高于初二年级,而未来职业内部归因显著低于初二年级;公立学校流动儿童则表现出了性别差异,男生在各领域上的外部归因和乐观性均显著高于女生;(3)教育计划和乐观性对流动儿童的行为卷入得分有显著的正向预测作用,教育的外部归因和未来的职业计划有着显著的负向预测作用;流动儿童的未来受教育计划、教育目标和乐观性以及职业的内部归因对其心理卷入有显著的正向预测作用。
