学前儿童抑制控制的发展趋势及其对言语理解和数学认知的预测作用

以长春市某幼儿园的122名3~6岁幼儿为被试,采用2(测试任务:无嵌套规则白天黑夜任务,有嵌套规则的白天黑夜任务)×2(测试时间:间隔9个月的第一次测试和第二次测试)×4(年龄分组:3.00~3.75岁组,3.76~4.50岁组,4.51~5.25岁组,5.26~6.00岁组)的三因素混合设计,来分析不同复杂程度的抑制控制在学前阶段的发展趋势,并在控制幼儿年龄和工作记忆水平后,分析不同复杂程度抑制控制对言语理解和数学认知的独立预测作用。结果发现:(1)对3~6岁儿童来说,有嵌套规则的白天黑夜任务的难度水平要显著高于无嵌套规则的白天黑夜任务;(2)较简单的抑制控制(无嵌套规则的白天黑夜任务)在学前阶段的发展速度先快后慢,但较复杂的抑制控制(有嵌套规则的白天黑夜任务)在3~6岁期间持续快速发展;(3)独立于年龄和工作记忆,较复杂的抑制控制能够显著预测幼儿的数学认知和言语理解,但较简单的抑制控制对言语理解和数学认知的预测作用不显著。根据上述结果,在描述学前儿童抑制控制发展趋势时要注意任务难度的设定,而且难度适当的抑制控制任务成绩更能预测幼儿的言语理解和数学认知。     

智力测验分数解释的发展趋势

智力测验分数的解释是智力心理学一个重要的研究领域。智力测验分数解释最基本的一个目的就是为了理解。随着智力理论和智力测验的发展,智力测验分数的解释出现了一些新的特点与趋势即注重智力测验分数解释的理论基础,注重智力测验分数解释的效度丰富化与从有用信息的抽取来解释测验分数的趋向。     

儿童的人际运动同步

人际运动同步是一种“社会胶粘剂”,能促进儿童产生更多的亲社会行为。儿童的人际运动同步能力随着年龄的增长不断提升,其同步表现受到运动方式、节奏刺激类型、同步对象等因素影响。在人际运动同步过程中,时间感知、运动计划和运动执行三大认知因素参与其中,既制约着个体同步能力的发展,也影响个体同步的表现。孤独症作为一种神经发育性障碍,孤独症儿童表现出异常的人际运动同步。未来的研究不仅要探讨孤独症儿童人际运动同步的异常机制,还要更多关注人际运动同步训练在孤独症群体中的实际应用和干预效果。     

信号检测论在测定“人肉搜索”参与者社会认知辨别力中的应用

采用"人肉搜索结果期待问卷"对225位"人肉搜索"参与者进行在线问卷调查,运用UlehlaAdams构建的信号检测模式进行数据分析,以期探讨参与者的社会认知辨别力(Social Cognitive Discriminability,SCD)及其主要影响因素。结果表明:(1)参与者群体具有一定的SCD(d′=0.61±0.44),即对公权信息和私权信息具有一定的区分能力,且反应偏向β适中(1.24±0.39);(2)性别、受教育程度、月收入和上网时长对SCD及各分测量指标的影响均不显著,而不同居住地参与者的SCD差异边缘性显著,且在"自我体验"分测量指标上差异显著;(3)在"搜集信息"和"社会参与"上具有不同活动倾向的参与者,其SCD具有显著差异,且在"自我体验"和"同伴认同"分测量指标上也有显著差异。可见,SCD主要受参与者上网活动倾向的影响。     

Having versus doing: The roles of moral identity internalization and symbolization for prosocial behaviors

Moral identity has been identified as a consistent predictor of prosocial behavior, but the specific relationship and predictive strength of its two dimensions, internalization (“having”) and symbolization (“doing”), are less clear. The current article explores this through two self-report studies. In study 1 (N = 228) a series of hierarchical regression analyses showed that, for three out of four domains of prosocial behavior, symbolization was the only significant predictor, and that its strength differed across outcomes. Building on these results, Study 2 (N = 299) proposed that the observed vs. anonymous nature of prosocial behavior could account for these differences. Unexpectedly, symbolization predicted both public and private behaviors, whereas internalization generally did not. Significant interactions between internalization and symbolization were also observed. These findings are discussed in relation to their theoretical implications and future moral identity research.     

Not all gifts are good: The potential practical costs of motivated gifts

People rely on support from others to accomplish mundane and momentous tasks. When asking for assistance, is it beneficial to incentivize a helper by offering a motivated gift (i.e., a gift with the hope of getting support in return)? Six studies (N > 2,500) examine the frequency and potential costs of motivated gifts. In Study 1, a third of Americans indicated that they had given a motivated gift at least once, while nearly two‐thirds believed they had received one. In Studies 2a–d, most participants who imagined receiving a motivated gift before a favor request reported lower willingness to help and anticipated satisfaction from helping than participants who imagined simply being asked for a favor. Finally, Study 3 replicates these findings with actual help provided among friends in a laboratory setting. Findings suggest that motivated gifts are relatively common but may sometimes undermine the assistance that people hope to receive.     

Honesty‐humility and prosocial behavior: The mediating roles of perspective taking and guilt‐proneness

The prosocial personality trait of honesty‐humility has received extensive attention in the last decade. However, research on the mechanism underlying the relationship between honesty‐humility and prosocial behavior is rather scarce. This study aims to explore the internal mechanism underlying this relationship to draw a complete picture of the honesty‐humility trait. A sample of 458 Chinese young adults was obtained to complete self‐report measures of honesty‐humility, perspective taking, guilt‐proneness, and prosocial behavior. The mediation model revealed that: (1) honesty‐humility positively related to prosocial behavior; (2) perspective taking and guilt‐proneness mediated the relationship between honesty‐humility and prosocial behavior, separately; and (3) the effect of honesty‐humility on prosocial behavior was mediated via perspective taking and then guilt‐proneness. In conclusion, we provide an initial support for the mediating roles of perspective taking and guilt‐proneness in the relationship between honesty‐humility and prosocial behavior. Both theoretical and practical implications for understanding the psychological mechanisms of prosocial behavior are discussed.     

海洛因成瘾者复吸倾向的研究

目的：探讨海洛因成瘾者复吸倾向的影响因素。方法：采用“复吸倾向问卷”对289名戒毒劳教人员进行测评。结果：发现戒毒意愿、将来环境、身心状态、物质替代和社会支持是影响复吸倾向的五个因素。这个结果提示在海洛因成瘾者的康复治疗中应该采用“药物——心理——社会”模式。     

暴力视频游戏对个体亲社会性的影响：一项元分析

暴力视频游戏是一种新兴的娱乐媒介, 是指含有描绘个体试图对其他个体造成伤害等内容的视频游戏。亲社会性是人类区别于动物的重要特征, 包括在人际交往中个体所表现出的利他、助人等一切使他人受益的认知、情感和行为。本文采用元分析的方法整合国内外已有研究, 分析暴力视频游戏对玩家亲社会性影响的主效应, 并重点考察各调节变量在暴力视频游戏与亲社会性的关系中产生的作用。通过文献检索, 纳入符合要求的文献24篇, 包含63个效应值(effect size), 总样本量18554人。研究结果显示：暴力视频游戏与亲社会性总效应值显著, 但相关较弱(r = -0.10)。调节效应分析表明, 暴力视频游戏与亲社会性的关系受到被试性别、被试类型、被试年龄、测量类型与亲社会性测量指标的调节。未来研究可以进一步采用一般攻击模型与一般学习模型等理论模型指导暴力视频游戏对亲社会行为影响研究, 同时优化实证研究中测量亲社会性的实验范式, 并且需要重点考察个体差异对暴力视频游戏与亲社会性关系的影响。
