Tempo discrimination in infants

An habituation/dishabituation paradigm demonstrates that 2- and 4-month-old infants are able to discriminate auditory sequences that vary slightly in tempo. Discriminations were only observed for intermediate tempi (600 ms but not 100, 300, 1500 ms IOI), suggesting that infants have the same optimal tempo range as adults.     

The Antinomies of Collective Political Trauma: A Pre-Theory

Prime Minister Yitzhak Rabin's assassination has less of a lasting impact on the Israeli public's political values, beliefs and attitudes than might have been anticipated from the magnitude of the event and intensity of the immediate responses. Why did the assassination have such a short-lived effect? This article considers the puzzle as a specific case of the broader phenomenon of collective political trauma and its consequences for values, beliefs and attitudes held by the mass public toward issues that it associates with the traumatic event. The article offers six deductively inferred hypotheses that describe, explain and link affective, cognitive and behavioral aspects of collectively experienced trauma. These hypotheses form a pre-theory explaining the perseverence of core political cognitions, even in the face of a considerable challenge to their validity and relevance.     

Linear Analogue Self-Assessment and Procrustean Measurement: A Critical Review of Visual Analogue Scaling in Pain Assessment

Visual analogue scales (VASs) are one of the most widely used self-report measures of clinical pain. This article reviews the empirical literature on linear analogue self-assessment (LASA) and critically examines the features that appear to have made it such an attractive measurement option in pain assessment. It is concluded that analogue scaling does not withstand critical scrutiny as a primary measure of either pain intensity or pain affect and that, in most circumstances, the overall clinical utility of VASs is inferior to that of more structured pain indices.     

时序信息的加工:自动还是控制

从长时记忆的角度出发,以故事的形式为实验材料,对时序信息的加工方式和通道效应进行了研究。结果表明,时序信息的加工存在视听通道效应,通道效应的机制源于记忆,且与加工方式有关。时序信息三个属性的加工方式不同：顺序属性倾向于自动加工;位置属性,就视觉信息来说倾问于自动加工,听觉在有顺序标码情况下倾向于自动加工、而在无顺序标码情况下则是一控制加工过程;间隔特性是一个控制加工过程。     

儿童运动视觉表象操作水平的发展及影响因素

采用计算机软件控制实验,以暴露运动一段行程后进入遮蔽的光点为刺激物,光点以三种不同运动速度、三种不同运动行距组合呈现,要求儿童判断光点到达目标位置时按键反应。结果表明：5—19岁儿童运动视觉表象操作水平的发展存在5一8岁、11—14岁两个加速期;客体运动速度对运动视觉表象操作绩效有显著影响,5、8、11岁组快速较中速下．5．8岁组中速较慢速下操作准确性均有显著降低;客体运动行距对运动视觉表象操作绩效也有显著的影响．5、8、11岁组右目标位置下较中目标位置下操作准确性显著降低;性别对运动视觉表象操作水平无显著影响。

Precuing the Target Location in Visual Searching by a Chimpanzee (Pan troglodytes): Effects of Precue Validity

A chimpanzee ( Pan troglodytes ) performed a visual search task using a modified matching-to-sample procedure in which a sample stimulus was followed by the search display, which contained one stimulus identical to the sample (target) and several uniform stimuli different from the sample (distractors). On cued trials, while the subject was observing the sample, a white square (precue) appeared at the location where the target was to be presented (valid trials), or elsewhere (invalid trials). The validity of the precue (correspondence between the cued and the target locations) was changed from 0% to 100% across conditions. Cost-benefit analyses were performed on the difference between valid and noncued trials (benefit) and between invalid and noncued trials (cost). Under the high-validity conditions, the response times were shorter when the cued location corresponded to the target location than when the precue did not appear. When the cued location did not correspond to the target location, on the other hand, the subject took longer to select the target than on noncued trials. When the validity of the precue was relatively low, however, cost of the invalid trials disappeared, while benefit of the valid trials remained. These results confirmed the two-process (automatic and attentional) theory of priming in human information processing; the advance information had the same effects on a chimpanzee's visual search performance as on humans'.     

Risk perception and the location of a repository for spent nuclear fuel

This study investigates lay people's reactions to a repository for nuclear waste. Risk perception is seen as a complex concept, comprising both affective and cognitive components. Attitude towards nuclear power and trust in experts and authorities had a substantial impact on risk perception, while personal knowledge about nuclear waste disposal had no effect. Thus, the more positive one's attitude towards nuclear power is and the more trust one has in experts and authorities, the lower one's risk perception is. Also, reactions were expected to vary with distance between the home district and the location of a repository. These variations differed in nature for people with alternative levels of risk judgement. The distance between the home and a repository affected approval of the proposed site. Distance between home and repository also had an effect on risk feelings and somewhat less on beliefs about consequences. Estimated total risk was directly mediated by beliefs about consequences, but even more so by risk feelings. With regard to risk, one can conclude that it is important to make a distinction between an emotional and a cognitive component of risk perception.     

5-11岁儿童元知觉发展的实验研究

本项研究旨在探索 5 -1 1岁儿童元认知发展的规律 ,2 80名昆明市及路南县汉、撒尼族儿童参与了三项知觉实验 ,实验结果表明 :1儿童随年龄的增长 ,有关知觉组织策略的知识及自我监察的能力也逐渐发展 ,表现为系统观察、选取有效策略及计划性的增强。 2儿童对信息的加工不断深入 ,从表浅的加工过渡到详尽的加工 ,不仅要求补充必要的信息 ,而且主动搜索隐蔽的线索以促进识辨。3儿童自我评价从笼统、含糊逐渐向客观、全面发展。4路南儿童元知觉的发展晚于昆明儿童两年 ,但在路南的汉族儿童和撒尼族儿童之间不存在显著差异 ,说明文化教育对儿童元知觉发展的重要影响。     

动词语义和句子语法对代词加工的影响

考察了动词语义和句子语法对代词加工的影响．结果表明,动词语义是影响代词理解的一个因素;相同语法功能假设尚需进一步验证,研究者还提出代词理解受社会文化因素影响的假设。
