视觉刺激探测的警觉性注意特征初探

采用"预警提示-目标探测"范式,对视觉刺激探测的警觉性注意特征进行初步探索。实验一表明,随着预备到目标刺激的时间间隔(interstimulus interval,ISI)变化,固定位置上探测目标刺激的速度也随之变化,并且对大概率刺激的探测更快,表现出了警觉性注意的稳定性和选择性特征。实验二进一步考察了目标刺激在不同ISI和不同空间位置的情况,除发现与实验一相似的结果以外,被试探测目标刺激的速度随注意视角增大而下降,表现出了警觉性注意的集中性特征。     

“有”、“无”之辨——《老子》第一章再读解

<正>《老子》第一章是老子"道"论的总纲,也可视为整部《老子》的眼目。"道"("恒道")由此而定其所导,"名"("恒名")由此而明其所谓;老子之属意,于此可窥其大略。自《韩非子》以至于汉魏以降,《老子》注疏之众不可胜数,而诸注之意境则大都可从其对于第一章的诠释判别高下。今以帛书《老子》为底本,参酌世传碑、刻、注本,于前贤思绎之未尽处对《老子》第一章再作申解,以期寻取"众眇"所通而我心所契的玄理之门。或有未当,方家正焉。     

基本药物制度对首诊制的影响及对策研究

基本药物制度实施后,药品价格降低,医保报销比例增加,有利于吸引患者到社区医疗机构就诊,促进了首诊制发展,但由于基本药物种类有限,居民用药习惯以及财政补偿不到位等都影响了基层卫生机构的功能发挥,不利于首诊制的发展.基本药物制度在实施中要不断完善,最终达到与首诊制共同发展的双赢局面.     

低治愈率患者医疗损害救济研究

低治愈率患者受到医疗损害后,难以依照传统因果关系理论证明其最终损害与医疗过失行为间存在因果关系,故无法得到赔偿.在我国现行法律框架内,可转换最终损害概念,借鉴国外“期待权理论”处理相关问题.但“生存可能性”是统计学结论,若具体患者生存可能性实际并未降低,被告的侵权损害责任不能成立.     

More Than Two Choices: The Influence of Context on the Framing Effect

The framing effect demonstrates that two options with different risk levels affect people??s risk preferences, even if both options are logically equivalent. However, in reality we are almost always confronted with more than two choices, rather than a single manipulated message. In this paper, we simultaneously manipulate the framing effect and the context effect, including the attraction effect and the compromise effect, to examine the influence of context on framing. The results of two studies show that context influences the original choice preference arising from the framing effect. Moreover, the framing effect is reduced when context effects are introduced to the original choice set.     

Effects of validity screening items on adolescent survey data

In 2 studies, we examined the use of validity screening items in adolescent survey data. In each study, adolescent respondents were asked whether they were telling the truth and paying attention in answering survey questions. In Study 1 (N = 7,801), the prevalence rates of student risk behaviors were significantly lower after inappropriate (invalid) responders were screened out of the sample. In addition, confirmatory and multigroup factor analyses demonstrated significant differences between the factor structures of school climate scales with valid versus invalid responders. In Study 2, student perceptions of school climate were correlated with teacher perceptions in 291 schools. A bootstrap resampling procedure compared the correlations obtained with valid versus invalid responding students in each school and found that valid responders had more positive views of school conditions and produced higher correlations with teacher perceptions. These findings support the value of validity screening items in improving the quality of adolescent survey data.     

Ontogeny of classical and operant learning behaviors in zebrafish

The performance of developing zebrafish in both classical and operant conditioning assays was tested with a particular focus on the emergence of these learning behaviors during development. Strategically positioned visual cues paired with electroshocks were used in two fully automated assays to investigate both learning paradigms. These allow the evaluation of the behavioral performance of zebrafish continuously throughout development, from larva to adult. We found that learning improves throughout development, starts reliably around week 3, and reaches adult performance levels at week 6. Adult fish quickly learned to perform perfectly, and the expression of the learned behavior is manifestly controlled by vision. The memory is behaviorally expressed in adults for at least 6 h and retrievable for at least 12 h.     

Confucian dynamism work values and team performance: A multiple‐level analysis

In this study we clarified the multiple‐level effects of Confucian‐related work values, including self‐discipline and interpersonal ethics, on the performance of individuals and the team. Empirical data of 70 work teams with 472 team members from Taiwanese enterprises were collected to test our hypotheses. Results showed that, at the group level, shared team values of interpersonal ethics were positively related to team performance through the partial mediation of team cooperation. For cross‐level effect, shared team values of interpersonal ethics and individual member's self‐discipline values were both positively related to individual performance. The implications of Confucian dynamism work values on contemporary organizational management and indigenous Chinese team theories were provided.     

Academic achievement in Norwegian secondary schools: the impact of violence during childhood

Using data from a national survey (N = 6,979) of young people in their last year in Norwegian secondary schools in 2007 (aged 18 and 19), this paper examines the effect of experience of violence including sexual abuse during childhood (before the age of 13) on the later academic achievement of young people. This investigation includes three types of violence: non-physical, physical and sexual, and two types of victimisation: being abused and witness to abuse. First we investigate the relationship between the experience of various violent acts before the age of 13 and young people??s later academic achievement. Second, applying the structural equation modelling technique, we take into account the effect of background factors such as parents?? educational attainment and gender, and the effect of mediating factors such as social capital and educational motivation on the academic achievement of the young victims. The results show that exposure to violence during childhood not only directly influences young people??s educational outcomes but also exerts indirect influences on their achievement through its impact on young victims?? social relations and psychological health.     

The preference for potential

When people seek to impress others, they often do so by highlighting individual achievements. Despite the intuitive appeal of this strategy, we demonstrate that people often prefer potential rather than achievement when evaluating others. Indeed, compared with references to achievement (e.g., "this person has won an award for his work"), references to potential (e.g., "this person could win an award for his work") appear to stimulate greater interest and processing, which can translate into more favorable reactions. This tendency creates a phenomenon whereby the potential to be good at something can be preferred over actually being good at that very same thing. We document this preference for potential in laboratory and field experiments, using targets ranging from athletes to comedians to graduate school applicants and measures ranging from salary allocations to online ad clicks to admission decisions.
