Learning without consciously knowing: Evidence from event-related potentials in sequence learning

This paper investigated how implicit and explicit knowledge is reflected in event-related potentials (ERPs) in sequence learning. ERPs were recorded during a serial reaction time task. The results showed that there were greater RT benefits for standard compared with deviant stimuli later than early on, indicating sequence learning. After training, more standard triplets were generated under inclusion than exclusion tests and more standard triplets under exclusion than chance level, indicating that participants acquired both explicit and implicit knowledge. However, deviant targets elicited enhanced N2 and P3 components for targets with explicit knowledge but a larger N2 effect for targets with implicit knowledge, revealing that implicit knowledge expresses itself in relatively early components (N2) and explicit knowledge in additional P3 components. The results help resolve current debate about the neural substrates supporting implicit and explicit learning.     

The Best Friend and Friendship Group Influence on Adolescent Nonsuicidal Self-injury

This study examined associations of peer socialization and selection, over time, with nonsuicidal self-injury (NSSI) among 5,787 (54.2 % females) Chinese community adolescents. Both effects were tested using two aspects of adolescents’ friendship networks: the best friend and the friendship group. Participants completed questionnaires assessing NSSI, depressive symptoms and maladaptive impulsive behaviors at two waves of time over a 6-month period. Results showed that even after controlling for the effects of depressive symptoms and maladaptive impulsive behaviors, the best friends’ engagement in NSSI still significantly predicted adolescents’ own engagement in NSSI. Adolescents’ friendship groups’ NSSI status also significantly predicted their own NSSI status and frequency. Additionally, adolescents with NSSI tended to join peer groups with other members also engaging in NSSI.     

A Framework for Summative Evaluation in Informal Science Education

ABSTRACT

Summative evaluation plays a critical role in documenting the impacts of informal science education (ISE), potentially contributing to the ISE knowledge base and informing ongoing improvements in practice and decision-making. In response to the growing demand for capacity-building in ISE evaluation, this article presents a framework for summative evaluation based on an extensive review of literature and research-based refinements. The framework synthesizes key elements of high-quality summative evaluation into three dimensions: (a) Intervention Rationale, (b) Methodological Rigor and Appropriateness, and (c) Evaluation Uses. Judgment of the value of the intervention (e.g., program, exhibition) should draw upon all three dimensions.     

A China–New Zealand comparison of forgiveness

The present study examined the practice of forgiveness among participants from China (N = 172) and New Zealand (N = 91). We tested a theoretical model describing the relationships between collectivism, individualism, and forgiveness. Participants from China were more collectivistic and less individualistic than were participants from New Zealand. Overall, participants from New Zealand were more forgiving than were participants from China. Collectivism was positively related to decisional forgiveness in Chinese participants. Decisional forgiveness independently predicted conciliatory behaviour among participants from China, but this was not the case for participants from New Zealand. Thus, the hypothesized model received qualified support.     

汉族、基诺族及布朗族7～9岁儿童心理旋转能力的比较研究

该研究探讨了我国7～9岁汉族、基诺族、布朗族儿童的“心理旋转”能力,了解不同民族的文化背景、年龄及性别差异是否对“心理旋转”产生影响。结果表明：汉族儿童的结果与基诺族及布朗族儿童结果存在明显差异,7～9岁儿童的心理旋转能力随着年龄增长而发展。未见男女性别上存在“心理旋转”能力上的差异。     

中学生厌学心理及其干预与学习效率的相关研究

本研究旨在考察两个问题：1．心理咨询是否是改变中学生厌学心理的有效途径,如果是,它能够在多大程度上改变厌学心理;2．厌学心理的改善能否有效提高中学生学习效率。本实验用问卷调查法从183名中学生中筛选出有厌学心理的学生24名。运用个体心理咨询、团体心理咨询等手段对这24名学生进行为期4个月干预、结果表明：心理咨询能够有效且明显地改善厌学心理。但要完全消除厌学心理则还需要辅以其他干预手段;随着学生厌学心理的改善,其学习效率也相应有了明显的提高。     

相互作用的认知子系统理论述评

该介绍和分析了“相互作用的认知子系统”理论的基本观点,即信息的意义分为具体的、低层次的意义和一般的、高层次的意义;编码形式的转换遵循着特定的规则;不同信息的存储具有各自独立的记忆存储系统：高层次的意义对情绪产生具有直接作用。同时阐述了该理论对抑郁性情绪障碍的研究,并指出了该研究对治疗情绪障碍的意义及存在的问题。     

低色温低强度背景光照射下液晶显示颜色编码的实验研究

采用一台有源矩阵彩色液晶显示器作为主要实验装置,对低色温、低强度背景光照射下液晶显示颜色编码范围及其与色标大小的关系进行了研究。实验结果表明:(1)液晶显示器上色标大小对绝对辨认效果有显著影响,随着色标的增大,辨认错误率随之下降,但下降率则随色标的增大而递减。(2)在色温为3100K的低强度背景光照射下,液晶显示的颜色编码范围因色标大小不同而存在显著差异,当色标面积减小到1×1mm2至2×2mm2时,编码色数目仅限于3-4种。     

内外部线索对学习判断的影响

该研究针对Koriat和Dunlosky实验研究结果的不同,通过两个实验,进一步考察内外部线索对学习判断（judgment of learning,简称为JOL）的影响。被试为山东师大本科生63名。内部线索词对的语义联系,两种外部线索分别是呈现时间和呈现顺序。本研究结果表明：（1）无论在交替呈现还是区组呈现条件下,内部线索对JOL和回忆都产生了显著影响;（2）呈现顺序和呈现时间可能是两种不同类型的外部线索;（3）不同的内外部线索对JOL有不同的交互作用;（4）实验二中无意义词对先呈现组的JOL大于有意义词对先呈现组的JOL,这说明JOL可能存在“锚定效应”。     

Group boundary permeability moderates the effect of a dependency meta‐stereotype on help‐seeking behaviour

Previous studies have found that when low‐status group members are aware that their in‐group is stereotyped as dependent by a specific out‐group (i.e. a dependency meta‐stereotype is salient), they are reluctant to seek help from the high‐status out‐group to avoid confirming the negative meta‐stereotype. However, it is unclear whether low‐status group members would seek more help in the context of a salient dependency meta‐stereotype when there is low (vs. high) group boundary permeability. Therefore, we conducted two experiments to examine the moderating effect of permeability on meta‐stereotype confirmation with a real group. In study 1, we manipulated the salience of the dependency meta‐stereotype, measured participants' perceived permeability and examined their help‐seeking behaviour in a real‐world task. Participants who perceived low permeability sought more help when the meta‐stereotype was salient (vs. not salient), whereas participants who perceived high permeability sought the same amount of help across conditions. In study 2, we manipulated the permeability levels and measured the dependency meta‐stereotype. Participants who endorsed a high‐dependency meta‐stereotype sought more help than participants who endorsed a low‐dependency meta‐stereotype; this effect was particularly strong in the low‐permeability condition. The implications of these results for social mobility and intergroup helping are discussed.
