创造性认知重评在情绪调节中的迁移效应及其神经基础

认知重评在负性情绪调节中发挥着重要的作用。针对传统认知重评重构程度不够高、调节效果不明显的问题, 研究团队在先前的工作中提出了一种使消极情绪“转负为正”的高效情绪调节方法, 即创造性认知重评, 这种调节策略伴随着大脑海马的新颖联结形成和杏仁核的积极情绪唤醒。然而这些工作采用“指导式”的重评更像是对重评解读的“理解”而非主动的情绪调节; 鉴于主动情绪调节的产生难度较大, 造成创造性认知重评在实际应用上的两难困境。基于此, 本项目拟指导受试者进行创造性认知重评的学习, 通过学习将这种策略迁移并且应用到生活中的负性情绪调节事件中。具体研究内容包括：(1)行为学上, 探索创造性认知重评在大学生群体和青少年群体负性情绪调节中的迁移效应; (2)影像学上, 探索创造性认知重评迁移前后在脑认知表征模式上的变化。本项目是对已有工作基础的延伸和拓展, 为验证和推动创造性认知重评成为一种可学、可用、高效的情绪调节策略奠定理论基础。     

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.     

The effect of achievement goals on enjoyment, effort, satisfaction and performance

This study examined the effect of achievement goals and achievement emotions on sport satisfaction, performance and effort among competitive athletes. Participants were 200 athletes. Structural equation modeling was used to test the indirect effect of mastery-approach goals on satisfaction with sport experience and performance, the direct effect of mastery-approach goals on enjoyment and effort, the direct effect of performance-approach and performance-avoidance goals on performance, and the direct effect of mastery-avoidance goals on effort. Results showed a positive direct effect of mastery-approach goals on enjoyment and an indirect effect, through enjoyment, on satisfaction, performance, and effort. We did not find support for the hypothesized effect of performance-approach or performance-avoidance goals on performance. The applied implications of endorsing mastery-approach goals are discussed.     

The sunk cost effect with pigeons: some determinants of decisions about persistence

The sunk cost effect occurs when an individual persists following an initial investment, even when persisting is costly in the long run. The current study used a laboratory model of the sunk cost effect. Two response alternatives were available: Pigeons could persist by responding on a schedule key with mixed ratio requirements, or escape by responding on a second key. In Experiment 1, mean response requirements for persistence and escape were varied across conditions. Pigeons persisted (committing the sunk cost error) when persisting increased the mean response requirement only slightly but not when persisting was sufficiently nonoptimal. Experiment 2 explored more systematically combinations of ratios and probabilities assigned to the schedule key. Persistence varied with the ratio of the mean global response requirements for persistence and escape. In Experiment 3, transitions between ratios were signaled. This reduced nonoptimal persistence, and produced some instances of a reverse sunk cost error--escaping when persistence was optimal. In Experiment 4, it was optimal to escape after the second-smallest ratio ever presented. Pigeons escaped at approximately the optimal juncture, especially in conditions with added signals. Overall, this series of experiments suggests that the sunk cost error may arise in part because persistence is the default behavioral strategy in situations where the contingencies for escape and persistence are insufficiently disparate and/or it is relatively difficult to discriminate when to escape. The study also demonstrates the utility of animal models of complex decision making situations.     

Explaining Own and Others' Behavior in a Controversial Issue: Animal Experimentation

Abstract

The authors investigated how 2 groups with different attitudes toward animal experimentation–researchers who conducted animal experiments and members of animal welfare organizations who protested against animal experiments–made attributions for the behavior of the opposing group. The 2 groups showed an actor-observer effect, mentioning more internal causes for the opponents' behavior and more external causes for their own behavior. Both groups were able to take the other's perspective, resulting in a reversed actor-observer effect. The less involved participants followed the pattern of ratings of the group whose attitudes corresponded to their own. In particular, the participants with a negative attitude toward animal experimentation rated researchers' behavior as more internally caused than did those with a positive attitude. The results illustrated how the participants formed and defended attitudes in a social context.
