形象度对图标内隐记忆和外显记忆的影响

记忆心理学领域大量研究证实了内隐记忆和外显记忆的ERP分离,且内隐记忆相比外显记忆在记忆容量、保持时间及稳定性上均有优势。实验记录了15名被试在内隐记忆任务与外显记忆任务中形象图标和抽象图标的行为及ERP数据。结果表明:内隐记忆中,形象图标的行为和300～500ms顶区差异波的启动量均显著高于抽象图标。外显记忆中,形象图标的外显记忆正确率显著高于抽象图标,而反应时无显著差异; 300～500ms额区的差异波,形象图标显著负向于抽象图标,而500～800ms顶区的晚成分差异波两者无显著差异。研究结果表明,形象图标在浅加工下进行无意识记忆具有明显的优势。形象图标与抽象图标在图形化界面语言的使用中一直存在争论,通过实验在行为指标与脑电生理指标上提供了量化证据。     

MA and Togetherness (Ittaikan) in the Narratives of Dancers and Spectators: Sharing an Uncertain Space

The Japanese concept/character MA (間), commonly translated as “gap, interval, or the in between,” partakes in many forms of Japanese arts and daily-life practices. In this article, we report the results of a qualitative research on the meaning or experience of MA and its relation with the feeling of togetherness in the context of contemporary dance improvisation. We interviewed performers and spectators (all professional dancers) while they watched the videotaped and reduced stick-figure versions of short dance improvisations created in a laboratory installed with motion-capture sensors. Based on the individual narratives, and inspired by Japanese and occidental aesthetic writings, we elaborate a specific understanding of MA as attending to the event's preacceleration, and how this experience causally relates to the feeling of togetherness (一体感, ittaikan). We propose that MA, understood not extensionally (as an empty space or a silent gap), but intentionally/internally as a certain quality of attention or perceptual mode, is fertile ground for serendipity. MA as an interpersonal ethical construct suggests a transsubjective difference as a foundation for a collective coming together.     

A consumer-grade LCD monitor for precise visual stimulation

Because they were used for decades to present visual stimuli in psychophysical and psychophysiological studies, cathode ray tubes (CRTs) used to be the gold standard for stimulus presentation in vision research. Recently, as CRTs have become increasingly rare in the market, researchers have started using various types of liquid-crystal display (LCD) monitors as a replacement for CRTs. However, LCDs are typically not cost-effective when used in vision research and often cannot reach the full capacity of a high refresh rate. In this study we measured the temporal and spatial characteristics of a consumer-grade LCD, and the results suggested that a consumer-grade LCD can successfully meet all the technical demands in vision research. The tested LCD, working in a flash style like that of CRTs, demonstrated perfect consistency for initial latencies across locations, yet showed poor spatial uniformity and sluggishness in reaching the requested luminance within the first frame. After these drawbacks were addressed through software corrections, the candidate monitor showed performance comparable or superior to that of CRTs in terms of both spatial and temporal homogeneity. The proposed solution can be used as a replacement for CRTs in vision research.

征兵用数字搜索测验的研制

基于信息加工速度理论自编征兵用数字搜索测验,使用该测验对全国15735名应征青年及190名新兵进行了测量,3个月新兵营训练结束时由228上级对1900名士兵的智力相关工作绩效情况进行了调查,通过对上述数据的分析确定了测验方法及划界分数,并进行了信、效度检验。结果表明:缺失不同数字对题目难度有影响;划界分数为197秒正确应答27题以上;该测验的内部一致性α系数为0.864;预测符合率为95.7%。     

汉字认知倒置效应的行为学研究

通过比较被试对相同刺激在不同诱导条件和不同特征变化条件下的认知的异同,探索倒置效应对认知的影响及机理.结果发现:当呈现的刺激被诱导为汉字认知时,仅在结构变化条件下出现倒置效应;而同样的刺激被诱导为字母组合被加工时,在结构和细节变化时均不会出现倒置效应.研究结果揭示了激活诱导效应对认知的重要影响,支持了专家假说对倒置效应的解释,进一步说明了结构和整体加工对专家系统的重要意义.     

孝文化与中国人人格形成的深层机制

作为中国文化的重要特征,孝文化提供了一整套系统的文本、言说和行为准则,不仅影响到中国社会的历史面貌和现实状况等宏观领域,而且也影响到人格形成等微观领域。该文从文化的辩证角度分析了孝文化长期存在的合理性,对孝文化的内涵和消极效应进行了心理学解读,并简要分析了孝文化与中国人具体人格特征之间的关联。正是通过具体的教养方式和亲子关系,孝文化完成了其对人格的塑造作用。
