自尊对主观幸福感的影响：有调节的中介效应

采用问卷法调查了1084名高一至大四的学生,探讨了自尊、主观幸福感、自我怀疑及抑郁的关系。结果发现：自尊在自我怀疑与主观幸福感之间起部分中介作用,这一中介作用的实现受到抑郁的调节,即自尊对主观幸福感的影响是有调节的中介效应。

The Enhancing Effect of Overconfidence on Subsequent Learning Performance: Potential Mediation Effects of Dissatisfaction and Effort

Three studies were conducted to investigate whether individuals whose performance on a learning task fell short of their previous overconfident self‐assessment would apply more effort on a subsequent task to resolve their dissatisfaction and thereby achieve better subsequent performance than individuals who made accurate or underconfident self‐assessments. Specifically, Study 1 and Study 2 used overestimation, and Study 3 used overplacement to predict subsequent performance by measuring students' self‐assessments before the first task, their level of dissatisfaction with their actual performance on that task, the effort they applied in learning, and their performance on the subsequent task. Furthermore, Study 3 divided the participants randomly into a false feedback group (the control group) and a real feedback group (the experimental group). The results showed that when controlling for prior performance, participants who were more overconfident tended to express greater dissatisfaction and increase more effort to achieve their desired outcomes when they perceived a gap between their desired performance and their actual performance. Notably, they achieved better subsequent performance, whereas those in the control group who were overconfident neither applied more effort in subsequent learning nor increased their subsequent performance when they received “unbiased feedback.” The implications of these findings for education are discussed.

工作记忆在时间和空间心理联结中的调节作用*

探讨时间的空间表征是否受到工作记忆的调节。实验将时间比较任务和工作记忆中的延迟匹配范式相结合。结果发现,记忆匹配条件下,刺激的空间位置不影响时间判断,而记忆不匹配条件下,当左侧刺激呈现的时间短,右侧刺激呈现的时间长时,时间判断的反应时更短。结果表明,时间的空间表征具有灵活性,受到工作记忆的调节。     

汉语发展性阅读障碍儿童的不同视野注意能力

以某城市小学三至五年级的学生为研究对象,筛选出发展性阅读障碍和同年龄对照组两组儿童,采用不同视角的刺激探测任务初步探查了汉语发展性阅读障碍儿童的不同视野注意能力及特点。研究使用圆点、数字和汉字三种刺激类型并设置了3°,12°,17°三种视角条件。结果发现,在数字和汉字条件下,汉语发展性阅读障碍儿童对刺激探测的反应时显著长于同年龄对照组儿童,说明在加工复杂刺激时,汉语发展性阅读障碍儿童可能存在知觉加工迟缓的缺陷。但是,汉语发展性阅读障碍儿童并没有表现出扩散的视觉空间注意模式,即更多地注意外侧视野的信息。汉语发展性阅读障碍儿童的视觉空间注意模式与正常儿童相似,表现为随着视角的增加,正确率降低,反应时延长。     

数目和呈现方式对时距估计的影响

采用口头估计的方法,考察刺激的数目和呈现方式对时距估计的影响。以时距估计的平均值、准确性和变异性为指标,结果表明：（1）数目多少影响时距估计的平均值和准确性,数目少引起低估,数目多导致高估,数目多少与时距长度一致时,准确性高。（2）呈现方式影响时距估计的变异性,同时呈现时变异性最大;（3）数目和呈现方式的交互作用显著,固定频率和变化频率呈现时,数目影响时距估计。（4）随着时距的增加,时距估计的平均值由高估向低估,准确性由低向高发展。这表明时距和数目在心理表征上存在连接,数目和呈现方式在不同的时间范围内影响     

有限理性的“占优启发式”和“齐当别”决策模型的作为 ——当Allais悖论杠杆撬动了期望效用理论

人们在做决策时常常要受到时间或知识的限制,有时还要受到其双重限制。关于人们是如何进行风险决策,早期有期望效用理论对其加以解释,但Allais悖论对其标准化地位提出了挑战。Simon的“有限理性”观点提出后,一些研究者开始致力于开发决策的“有限理性”模型。文章讨论并比较了无限理性的期望效用理论被Allais悖论杠杆撬动之后,有限理性的“占优启发式”和“齐当别”决策模型所能做的和所不能做的。两种模型的决策标准、计算策略以及未来研究的展望也一并作了讨论

Neural correlates of infant action processing relate to theory of mind in early childhood

The mechanisms that support infant action processing are thought to be involved in the development of later social cognition. While a growing body of research demonstrates longitudinal links between action processing and explicit theory of mind (TOM), it remains unclear why this link emerges in some measures of action encoding and not others. In this paper, we recruit neural measures as a unique lens into which aspects of human infant action processing (i.e., action encoding and action execution; age 7 months) are related to preschool TOM (age 3 years; n = 31). We test whether individual differences in recruiting the sensorimotor system or attention processes during action encoding predict individual differences in TOM. Results indicate that reduced occipital alpha during action encoding predicts TOM at age 3. This finding converges with behavioral work and suggests that attentional processes involved in action encoding may support TOM. We also test whether neural processing during action execution draws on the proto‐substrates of effortful control (EC). Results indicate that frontal alpha oscillatory activity during action execution predicted EC at age 3—providing strong novel evidence that infant brain activity is longitudinally linked to EC. Further, we demonstrate that EC mediates the link between the frontal alpha response and TOM. This indirect effect is specific in terms of direction, neural response, and behavior. Together, these findings converge with behavioral research and demonstrate that domain general processes show strong links to early infant action processing and TOM.     

The biochemistry of memory: The 26year journey of a 'new and specific hypothesis'

This Special Issue of Neurobiology of Learning and Memory dedicated to Dr. Richard Thompson to celebrate his 80th birthday and his numerous contributions to the field of learning and memory gave us the opportunity to revisit the hypothesis we proposed more than 25years ago regarding the biochemistry of learning and memory. This review summarizes our early 1980s hypothesis and then describes how it was tested and modified over the years following its introduction. We then discuss the current status of the hypothesis and provide some examples of how it has led to unexpected insights into the memory problems that accompany a broad range of neuropsychiatric disorders.
