文本阅读过程中信息的协调性整合

采用移动窗口阅读技术探讨文本阅读中信息的协调性整合问题。被试为华南师范大学本科生120名。实验材料按照主 人公特征与其目标句行为的关系总体上分为一致与恢复一致两个版本,每个版本都有两个目标句,出现在不同位置。实验1主 要探讨阅读过程中背景信息的激活与协调性整合的性质与特点,实验2主要探讨阅读过程工作记忆中前后信息的协调性整合 问题。采用相关样本t检验分别对两个目标句的阅读时间进行统计分析,结果发现,无论是通过共振激活的背景信息,还是保留 在工作记忆的文本信息,如果与新进入的文本信息有局部的不协调,那么就会产生协调性整合,整合的结果不仅维持了文本的连 贯,而且将相关的信息建构成整体的信息块     

Perceived Risks and Benefits in a Text Message Study of Substance Abuse and Sexual Behavior

To inform ethical procedures for human subjects research using mobile health (mHealth), we examined perceived risks and benefits of study participation among emerging adults (N = 54) with drug use who completed text message assessments of substance use and sexual behaviors. Most participants reported comfort with participation and some reported perceived benefits, such as improved relationships. Perceived risks were infrequently reported, including negative emotions and legal or financial concerns. In conclusion, participants from a vulnerable population reported few perceived harms of participation in longitudinal mHealth assessments of sensitive behaviors. Researchers should continue characterizing participants’ perspectives on ethical aspects of mHealth research.     

Emotionally arousing pictures increase blood glucose levels and enhance recall

Arousal enhances memory in human participants and this enhancing effect is likely due to the release of peripheral epinephrine. As epinephrine does not readily enter the brain, one way that peripheral epinephrine may enhance memory is by increasing circulating blood glucose levels. The present study investigated the possibility that emotionally arousing color pictures would improve memory and elevate blood glucose levels in human participants. Blood glucose levels were measured before, 15 min, and 30 min after male university students viewed 60 emotionally arousing or relatively neutral pictures. Participants viewed each picture for 6 s and then had 10 s to rate the arousal (emotional intensity) and valence (pleasantness) of each picture. A free-recall memory test was given 30 min after the last picture was viewed. Although the emotionally arousing and neutral picture sets were given comparable valence ratings, participants who viewed the emotionally arousing pictures rated the pictures as being more arousing, recalled more pictures, and had higher blood glucose levels after viewing the pictures than did participants who viewed the neutral pictures. These findings indicate that emotionally arousing pictures increase blood glucose levels and enhance memory, and that this effect is not due to differences in the degree of pleasantness of the stimuli. These findings support the possibility that increases in circulating blood glucose levels in response to emotional arousal may be part of the biological mechanism that allows emotional arousal to enhance memory.     

认知重评对负性效价的抑制促进条件性恐惧消退

认知重评能有效降低个体对情感刺激的负性情绪体验, 但指导性认知重评在恐惧记忆治疗中效果存在争议。本文将认知重评范式与辨别式条件恐惧反应范式结合, 以效价和US预期值为指标, 探讨指导性认知重评训练对恐惧情绪习得和消退的影响效果。以低认知重评能力个体为被试, 在实验前24 h进行指导性认知重评训练。条件性恐惧任务为期2天, 第一天完成条件性恐惧的习得和消退任务, 第二天完成条件性恐惧的再消退任务。结果显示, 经过重评训练后个体在条件性恐惧任务中的恐惧情绪效价显著较低, 说明认知重评有效降低低认知重评能力个体在急性应激状态下的负性情绪体验。所有被试均成功完成辨别式条件性恐惧的习得和消退任务, 因此重评训练并不削弱个体对危险或者安全信息的辨别能力。但在条件性恐惧的消退过程中, 认知重评指导训练加快了恐惧消退, 且24 h后测得的条件性恐惧程度显著较低, 说明指导性重评提高了条件性恐惧记忆的消退效率, 并减弱了条件性恐惧的消退返回。     

Drawing conclusions: Instructing witnesses to draw what happened to them

We reviewed the child and the adult literature on the impact of witnesses drawing what happened on the number of details recalled and the accuracy of the reported details. Most experiments reported a beneficial effect of drawing what happened (or drawing the scene) on the number of details reported primarily in free recall and sometimes also in cued recall. The consensus across studies was that drawing protocols did not negatively impact the accuracy of reported details (when accuracy was attainable) unless suggestive details were drawn. These results were largely consistent regardless of interviewer expertise or protocol used. Draw-and-tell instructions should be considered by forensic investigators for the following reasons: (1) the beneficial effect on number of details recalled with no detriment to accuracy, (2) the added benefit for children who need additional interviewer support, and (3) the ease at which the instruction can be implemented with minimal expertise or training. However, more ecologically valid research is needed to establish the efficacy of drawing (1) in forensic interviews, (2) in the presence of misinformation, (3) across instances of repeated event memory, and (4) across sequential interviews.     

无关言语对汉字短时记忆系列回忆的影响*

采用视觉呈现字表和听觉呈现无关言语方式,探讨在字表项目保持期间阻止被试复述情况下,不同呈现位置的无关言语对汉字短时记忆系列回忆的影响。在字表保持期间,采用计算任务进行分心作业。实验结果发现：(1)无关言语对汉字短时记忆系列回忆成绩存在显著影响;(2)在字表保持期间阻止被试进行复述消除了字表呈现期间呈现无关言语对回忆成绩产生的干扰效应;(3)汉字短时记忆系列回忆成绩表现出系列位置效应。实验结果没有完全支持客体情节记忆模型。     

重复获益效应对文本阅读加工的影响

通过三个实验分析比较同一篇文本前后两次阅读过程中每个句子的阅读时间,探讨汉语文本阅读中的重复获益效应。结果发现（1）汉语文本阅读中存在重复获益效应,并且被试倾向于对没有标题的文章命名;（2）产生重复获益效应的重要因素是在阅读过程中建立良好的情境模型;（3）当前后两篇文本的情境内容高度相关时,主要是情节重复效应影响文本阅读,当情境内容低相关时,抽象重复效应将影响文本的阅读。     

文章标记对高一学生阅读理解的影响

采用测验法,以64名高中一年级学生为被试,探讨文章标记对不同阅读水平学生的回忆成绩和问题解决的影响.结果表明:(1)不同阅读水平读者回忆成绩上的文章标记效应不显著;(2)文章标记对于不同阅读水平学生的问题解决都具有显著的影响作用;(3)不同阅读水平读者的回忆和问题解决成绩存在显著差异.     

Does self-acceptance captured by life narratives and self-report predict mental health? A longitudinal multi-method approach

We aimed to investigate the validity of different self-acceptance measures to predict mental health. Self-acceptance and negative life events, assessed via self-report and rated from life narratives (N = 149), served as predictors of mental health at baseline (T1) and four years later (T2). Path models showed distinguishable, complementary effects of self-reports and other-ratings. A moderate congruence of self- and other-ratings of self-acceptance was observed. Exploratory analyses revealed an association of self-acceptance with emotional words in life narratives. Controlling for negative life events, a positive link and a moderating effect of self-acceptance on mental health at T1, but no prediction of mental health at T2, were found. The study connects research on personality and narratives from a methodological and health psychological perspective.
