整合对联结再认和项目再认的促进作用：“只有收益”观点

研究旨在探讨整合如何影响联结再认和项目再认及其加工过程。编码阶段要求被试学习复合词和非复合词, 提取阶段完成联结再认和项目再认测验。结果显示, 复合词比非复合词有更好的联结再认表现, 但在项目再认表现上两者之间没有显著的差异。ERP结果显示, 在联结再认上, 复合词诱发显著的FN400效应(与熟悉性加工有关)和LPC效应(与回想加工有关), 非复合词只诱发显著的LPC效应, 且复合词比非复合词有更大的LPC效应。在项目再认上, 复合词比非复合词诱发更大的FN400效应。总而言之, 整合在促进联结再认的同时并不会损害项目再认的表现, 支持了“只有收益”观点。     

The left digit effect in a complex judgment task: Evaluating hypothetical college applicants

A left digit effect has been broadly observed across judgment and decision-making contexts ranging from product evaluation to medical treatment decisions to number line estimation. For example, $3.00 is judged to be a much greater cost than $2.99, and “801” is estimated strikingly too far to the right of “798” on a number line. Although the consequences of the effects for judgment and decision behavior have been documented, the sources of the effects are not well established. The goal of the current work is to extend investigations of the left digit effect to a new complex judgment activity and to assess whether the magnitude of the effect at the individual level can be predicted from performance on a simpler number skills task on which the left digit effect has also recently been observed. In three experiments (N = 434), adults completed a judgment task in which they rated the strength of hypothetical applicants for college admission and a self-paced number line estimation task. In all experiments, a small or medium left digit effect was found in the college admissions task, and a large effect was found in number line estimation. Individual-level variation was observed, but there was no relationship between the magnitudes of the effects in the two tasks. These findings provide evidence of a left digit effect in a novel multiattribute judgment task but offer no evidence that such performance can be predicted from a simple number skills task such as number line estimation.     

基于长尾效应的儿童创伤后应激障碍转归机制及干预策略

儿童PTSD具有“长尾效应”, 疾病负担重、发展结局存在较大异质性, 但是少有研究对我国儿童PTSD的转归进行系统性研究, 其转归类型、路径尚不明晰, 更缺少促进儿童PTSD复原的干预研究。因此, 本研究拟对儿童及青少年进行追踪调查和准实验研究, 探讨儿童PTSD的发展轨迹及转归类型和机制, 验证基于学校的综合干预服务对促进儿童PTSD恢复的效果, 为儿童PTSD干预及个性化诊疗提供证据。     

创造性思维的酝酿效应

酝酿效应是指当人们遭遇无法解决的难题时, 暂时将其搁置, 转而去完成其他无关任务, 反而有利于原有问题解决的现象。近年来, 研究者对创造性问题解决过程中的酝酿效应及其影响因素进行了广泛的研究, 同时提出了较多理论试图进一步解释酝酿效应。酝酿效应的代表性理论可分为“选择性遗忘理论”、“激活扩散和线索同化理论”、“无意识加工理论”等, 它们从不同角度解释了酝酿效应的机制, 并对其影响因素和有关现象各有预测。对心智游移和睡眠这些特殊形式的酝酿的研究进一步揭示了酝酿效应的机制。认知神经研究表明, 酝酿期的基本认知成分, 即表征重构和激活扩散, 涉及到前额叶、纹状体、海马体等多个脑区的协同合作。未来研究需要以深化理论建设为基础, 利用认知神经方法进一步揭示酝酿效应的机制, 从而更为深刻地认识创造性酝酿的本质。     

物体表征强度对基于动态物体的注意的影响

基于物体的注意已得到许多静态物体实验的证实, 然而, 对注意分配如何受动态物体影响的研究较少, 存在提示物体假设和动态更新假设两种观点。提示物体假设认为基于物体的注意由最初的物体决定, 而动态更新假设则认为由变化之后的物体决定。动态物体的注意研究还发现了即时物体效应, 即注意基于新物体进行。对于物体变化时注意究竟基于旧物体还是新物体, 新旧物体的相对物体表征强度在其中起决定作用; 当提示物体表征较强时表现为提示物体(即旧物体)决定注意分配, 而当即时物体表征较强时表现为即时物体(即新物体)决定注意分配。相对物体表征强度的概念对理解物体动态变化情况下基于物体的注意的分配以及解决相关理论之冲突可能有重要作用。     

“忠臣”还是“逆臣”？员工建设性越轨行为对主管绩效评价的非线性影响机制

整合社会交换和相似吸引理论,探讨了员工建设性越轨行为对主管绩效评价的过犹不及效应的作用机制和边界条件。实证分析结果表明：建设性越轨与主管绩效评价呈倒U形关系,领导感知的LMX在建设性越轨与主管绩效评价之间的倒U形关系中起完全中介作用,领导的建设性变革责任感在建设性越轨与LMX的倒U形关系中起负向调节作用。     

序列依赖效应——一种全新的“历史效应”

自2014年来, 研究者在视觉加工中发现一种全新的历史效应——序列依赖效应(当前刺激加工向先前刺激方向偏移的吸引性加工偏差)。近期研究发现：该效应广泛存在于视觉加工的各个层面(既包括朝向、空间位置、数量等低级特征, 也包括身份、吸引力、美感等高级属性); 其来源极为复杂(包括感觉编码、高级皮层的反馈调节、工作记忆、决策模板、感知与决策的级联等), 反映出不同层次的过往加工痕迹向当前认知的投射。针对该效应的典型特征、影响因素、认知与神经机制, 已涌现大量研究, 同时也存在严重争论, 亟待研究者深入探讨和厘清。     

快慢读者利用语境信息的差异：加工深度的作用

通过主题扫描和阅读理解两种加工深度不同的任务,考察快慢读者预测性效应差异的来源及加工深度在其中发挥的作用。被试在两种任务情境下阅读分别包含高低预测性目标词的96个句子框架,记录其眼动轨迹。结果显示：预测性效应仅在阅读理解任务中出现,快速读者在早期眼动指标上就表现出了预测性效应,慢速读者在晚期眼动指标上才表现出预测性效应。结果表明：加工深度调节快慢读者预测性效应的大小;在自然阅读情境下快慢读者的预测性效应表现符合预测编码框架假设。     

中文阅读中快速读者与慢速读者的词频效应

在熟练的中文阅读中,个体阅读效率越高,词汇加工效率是否越高,目前还缺少直接证据。本研究通过记录快速读者与慢速读者在阅读含有高频或低频目标词句子时的眼动轨迹来考察该问题。结果发现,在第一遍注视时间、回视路径时间和总注视时间上,快速读者对高频词与低频词的注视时间无显著差异,但都短于慢速读者;而慢速读者对低频词的注视时间显著长于高频词。即快速读者的早期词汇识别和后期词汇整合效率都较高,不受词频影响;而慢速读者的整个词汇加工效率较低,受词频影响较大。这些结果表明两组读者的词汇加工模式具有本质差异,符合个体差异性观点与词汇质量假说。     

The stability and causal effects of task‐specific and generalized self‐efficacy in college1

This research investigated the stability and causal effects of task‐specific self‐efficacy and generalized self‐efficacy in college students. In Study 1, task‐specific self‐efficacy and generalized self‐efficacy scales were administered to university students (N = 237) on two occasions, with an interval of 2 months. In Study 2, task‐specific (care‐work) self‐efficacy and generalized self‐efficacy scales were administered to college students who were studying to be care workers (N = 49) on three occasions (before the first care‐work practicum, after the practicum, and 3 months later). The results of both studies indicated that generalized self‐efficacy was more stable than task‐specific self‐efficacy. In Study 1, both generalized self‐efficacy and task‐specific self‐efficacy affected each other in daily life. Study 2 examined the effects of an ego‐engaged experience (the first care‐work practicum) for task‐specific (care‐work) self‐efficacy and generalized self‐efficacy. The results indicated that changes in care‐work self‐efficacy did not affect generalized self‐efficacy.
