药物产品责任的伦理研究

对药物产品责任的监管与立法必须与药物的特殊性相吻合。在药物的产品责任伦理上,社会公益至上是首要的;药物的产品责任伦理应该以安全性为基础,又必须对这种安全性的相对性予以确认,来确立对药物风险和危害的监管与控制,探讨了建设我国药物产品责任伦理与法制的举措。     

不同自我评价方式对高中生写作的影响

本研究考察了三种不同的自我评价方式对高中二年级学生写作活动的影响。结果表明,自我评价对写作成绩有一定改善,但短期内对一般性的学习动机与效能感无显著影响。写作结果自我评价方式有助于写作结果自我评价准确性的提高,单独的写作过程自我评价方式短期内对写作活动无显著促进作用,写作结果与写作过程的综合自我评价方式显著改善了写作活动。     

学习不良儿童对情绪表达规则的认知特点

采用儿童对情绪表达规则的认知访谈故事,比较了学习不良儿童和一般儿童对情绪表达规则认知的发展特点。结果发现,学习不良儿童表情调节知识水平显著低于一般儿童,性别差异不显著,组别与年级交互作用不显著,表明两组儿童发展趋势类似,发展水平不同;学习不良儿童报告出较少的社会定向目标,自我保护目标得分与一般儿童差异不显著;学习不良儿童缺少根据不同人际关系类型灵活运用情绪表达规则的知识,而且较少把情绪表达规则的使用和目标联系起来     

高中二年级学生双字词阅读知觉广度的眼动研究

采用“呈现随眼动变化技术”对12名高中二年级学生的双字词阅读知觉广度进行了眼动研究。结果发现：（1）高中二年级学生的双字词阅读知觉广度具有不对称性。（2）高中二年级学生的双字词阅读知觉广度为注视点左侧一个双字词到右侧两个双字词的空间。     

精细阐述与先行信息激活水平的动态变化

该研究运用窗口阅读及命名探测技术,对即时与延迟状态下合适与不合适背景信息的激活模式进行了探讨。被试阅读含有精细阐述错误信息的语篇,并对合适或不合适的探测词进行命名反应。结果发现,虽然即时条件下,受精细阐述的不合适探测词激活水平高于合适探测词,但当延迟时间为1500ms时,原有的激活模式发生了逆转。这种激活模式的变化主要是由于合适的背景信息随时程延长激活水平得到提升所致。     

篇章阅读中先行信息通达的若干影响因素

采用实时窗口阅读技术,探讨在篇章阅读理解中,当读者在建构先行信息已能考虑其合适与不合适这一条件下,先行信息与当前信息的关系及距离如何影响对先行信息的通达。实验一采用以句子为单位的自控阅读,通过再认探测技术,结果发现,被试在加工含回指词的目标句时,回指词的不合适先行词也会得以通达。实验二以词汇为单位呈现阅读材料,通过命名探测技术,结果发现,与当前回指词关系合适的先行词会得到更快的通达,而先行词与当前回指词距离的远近不会影响先行词的激活水平。     

Measuring misinformation in repeat trial pick 1 of 2 tests

An extension is described to a product testing model to account for misinformation among subjects. A misinformed subject is one who associates the taste of product A with product B and vice-versa; thus, the subject would tend to perform incorrectly on pick 1 of 2 tests. A likelihood ratio test for the presence of misinformation is described. The model is applied to a data set, and misinformation is found to exist. Biases due to model misspecificationand other implications for product testing are discussed.The first author is currently on leave from Carnegie Mellon University.     

Redundancy gain for categorical targets depends on display configuration and duration

Redundancy gain is an improvement in speeded target detection when the number of targets associated with a single response is increased within a single display. The effect has been clearly demonstrated with specific targets, but it is not clear if it occurs in categorization tasks with non-identical targets. The current study tested the effect of target redundancy on speed and accuracy in a go/no-go categorization task. Targets were digits tilted 45° to the left, and were displayed in unilateral, bilateral, or central displays for either 1500?ms or 100?ms. Redundancy gain only occurred for brief targets displayed bilaterally in the upper visual field. The results indicate that redundancy gain is possible for categorization tasks with some bilateral configurations, supporting a role for interhemispheric processing in redundancy gain. Additionally, the results may indicate that processing strategies mask redundancy gain when participants can view targets for a long period of time.     

Peering into the opaque mind

Abstract

Carolyn Saarni’s pioneering research showed that young children learn how to hide their feelings—to conceal disappointment with a smile or to conceal amusement with a neutral expression. By 6 years of age, children understand the implications of such concealment. They can distinguish between: (i) an individual’s true but hidden emotion; (ii) the emotion that the individual overtly expresses; and (iii) the emotion that other people might mistakenly attribute to the individual. Effectively, young children grasp that the mind is opaque. Its contents can remain hidden from others. We examine two issues raised by this important conceptual insight. First, we ask how it emerges in young children—what experiences lead them to acknowledge the mind’s opacity? Second, in light of Saarni’s emphasis on the impact of cultural beliefs and practices, we discuss anthropological evidence that in certain cultures the mind’s opacity is regarded as a social desideratum so that enquiries into, or speculations about, a person’s private mental states are regarded as inappropriate. We consider the understanding of hidden emotion that children will acquire if they grow up in such a culture. We propose—paradoxically—that they will readily differentiate between what is actually felt and what is overtly expressed. We conclude by reviewing recent cross-cultural evidence lending initial support to that prediction.     

睡眠剥夺与购物后悔：来自大规模个体层面数据的证据

睡眠剥夺正在成为人们面临的一种普遍问题,但是已有研究很少将睡眠剥夺与消费者行为联系起来。本文采用真实购物情境下的大规模消费者个体层面数据(N=1625472),通过建立计量经济学模型来研究睡眠剥夺与购物后悔的关系。结果表明,睡眠剥夺显著地增加了消费者的购物后悔倾向,具体在行为上表现为增加了商品的退货概率和加快了商品的退货速度。此外,商品的价格正向调节了睡眠剥夺对购物后悔的影响,而促销优惠金额的比例则负向调节了睡眠剥夺对购物后悔的影响。
