不同年龄倒班与正常班医护人员睡眠质量和睡眠规律性的比较

应用自行设计的睡眠调查表对443名20—45岁医护人员的睡眠质量和睡眠规律性作了调查。睡眠质量问卷包括睡眠一般评价、是否失眠及服药、入睡是否顺利、睡眠期间觉醒情况、梦记忆情况和觉醒期间精力情况六个项目。 调查结果发现倒班组与正常班组睡眠质量的差异表现在总分和几乎所有的项目上,倒班组值夜班后睡眠质量和睡眠规律性均很差;倒班组和正常班组睡眠质量均随年龄和工龄的增长而下降,因此倒班对睡眠的影响随年龄和倒班工龄的增长而加剧。本研究还发现,过去多年倒班、近三年前转为正常班的工作人员的睡眠有所恢复。     

对阅读理解监控及其发展的直接测量

Area activation: a computational model of saccadic selectivity in visual search

The Area Activation Model (Pomplun, Reingold, Shen, & Williams, 2000) is a computational model predicting the statistical distribution of saccadic endpoints in visual search tasks. Its basic assumption is that saccades in visual search tend to foveate display areas that provide a maximum amount of task‐relevant information for processing during the subsequent fixation. In the present study, a counterintuitive prediction by the model is empirically tested, namely that saccadic selectivity towards stimulus features depends on the spatial arrangement of search items. We find good correspondence between simulated and empirically observed selectivity patterns, providing strong support for the Area Activation Model.     

内隐序列学习表征方式的实验研究

采用Lewicki等人创造的“矩阵扫描”任务,对内隐序列学习的表征方式进行了研究。结果发现：规则试验的反应时显著低于随机试验,说明被试能够内隐地掌握复杂规则,没有证据表明这与“运动”频率的大小和序列样例的记忆有关;此外,序列结构也是影响内隐序列学习的因素之一。     

动词隐含因果性和重读对代词加工的影响

采用听觉动窗法和跨通道探测技术,设计3个实验考察了汉语口语句子理解中,动词隐含因果性和重读对代词加工的影响及其时间进程。其中的自变量为动词类型和韵律特征;探测实验中增加探测词类型变量。结果发现：动词隐含因果性影响代词的指认方向;当代词不重读时,动词隐含因果关系在遇到代词后立即影响代词可能先行词的激活水平。代词重读影响“因为”分句的阅读时间,且在代词后立即影响主语型动词语句中代词的加工     

任务转换条件下对特征的并行搜索

采用双任务范式,以两个实验探讨了任务设置与刺激特征的匹配程度对特征搜索方式的影响。要求被试首先辨认数字序列中包含的字母,随后完成特征搜索任务。在实验一中特征搜索任务是检测同时呈现的多个灰色圆点(干扰子）中是否有红色圆点(目标）出现。在实验二中,以多种不同颜色的圆点代替实验一中的灰色干扰子。结果发现：在特征搜索主要由自下而上的信息或自上而下的信息引导的两种条件下,任务设置与刺激特征的匹配程度均不影响特征搜索方式,特征搜索仍以并行方式进行。据上述结果笔者推测,在任务设置与刺激特征不匹配的条件下,视觉加工系统首先调整任务设置使二者相匹配,随后进行高效率的并行搜索,而非在二者不匹配的条件下进行低效率的系列搜索。     

自控速度的平滑滚动引导式和RSVP的文本阅读

考察了在自控速度条件下 ,显示窗口、起始速度和文本显示方式等因素对视频显示终端 (videodisplayter minals,VDT)汉语文本阅读工效的影响。结果发现 :(1)在阅读正确率上 ,VDT文本的平滑滚动引导式优于快速系列视觉呈现 (rapidserialvisualpresentation ,RSVP)方式 ;(2 )阅读速度和阅读理解成绩相互代偿 ,若注重理解正确率 ,宜采用 15 0字 /分的起始速度 ;若兼顾阅读速度 ,宜采用 75 0字 /分的起始速度 ;(3)起始速度、显示窗口和文本显示方式三者共同影响了阅读绩效 ;(4 )机控速度方式的阅读效率优于自控速度方式。     

"Robovie, you'll have to go into the closet now": children's social and moral relationships with a humanoid robot

Children will increasingly come of age with personified robots and potentially form social and even moral relationships with them. What will such relationships look like? To address this question, 90 children (9-, 12-, and 15-year-olds) initially interacted with a humanoid robot, Robovie, in 15-min sessions. Each session ended when an experimenter interrupted Robovie's turn at a game and, against Robovie's stated objections, put Robovie into a closet. Each child was then engaged in a 50-min structural-developmental interview. Results showed that during the interaction sessions, all of the children engaged in physical and verbal social behaviors with Robovie. The interview data showed that the majority of children believed that Robovie had mental states (e.g., was intelligent and had feelings) and was a social being (e.g., could be a friend, offer comfort, and be trusted with secrets). In terms of Robovie's moral standing, children believed that Robovie deserved fair treatment and should not be harmed psychologically but did not believe that Robovie was entitled to its own liberty (Robovie could be bought and sold) or civil rights (in terms of voting rights and deserving compensation for work performed). Developmentally, while more than half the 15-year-olds conceptualized Robovie as a mental, social, and partly moral other, they did so to a lesser degree than the 9- and 12-year-olds. Discussion focuses on how (a) children's social and moral relationships with future personified robots may well be substantial and meaningful and (b) personified robots of the future may emerge as a unique ontological category.     

If you can't grab it,it won't grab you: The effect of restricting the dominant hand on target evaluations

This research examines whether and how holding one object influences evaluations of another. Across four studies, we find that occupying the dominant (vs. non-dominant) hand leads to lower evaluations of the target object; further, process data suggests that this effect occurs because dominant hand restriction impairs the ease with which the perceiver simulates holding the target. Boundary conditions that document effect attenuation and reversal are also consistent with this premise. Collectively, the studies offer support for a circular chain of influence between the perception and action systems.     

学校资源与早期青少年心理社会适应的关系：一项潜在转变分析

以1012名初一学生为被试进行3年的追踪研究, 采用潜在剖面分析与潜在转变分析考察了早期青少年心理社会适应的亚组分化与转变情况, 以及学校资源与性别在青少年发展适应中的作用。结果发现：(1)初一时青少年的心理社会适应分化成2个亚组：适应良好组与内化问题组, 初二与初三时青少年分化成4个适应亚组：适应良好组、内化问题组、外化问题组和同伴拒绝组; (2)从初二到初三, 适应良好组和内化问题组的青少年保持了较高的稳定性, 同伴拒绝组和外化问题组的青少年向适应良好组转变的概率最高; (3)拥有更多学校资源的青少年更可能处于或保留在适应良好组, 同时在初二时拥有更多学校资源的外化问题组和同伴拒绝组的青少年在初三时更可能向适应良好组转变; (4)初二时女生更大概率地进入内化问题组。研究结果有助于深化对早期青少年心理社会适应发展模式多样性的理解, 并提示教育人员有必要对青少年适应状况进行全面筛查和动态监测, 以便针对适应亚组和性别特点制定更为复杂的预防和干预方案。
