Metacognitive Experiences and Human Judgment: The Case of Hindsight Bias and Its Debiasing

ABSTRACT— Theories of judgment have emphasized the influence of what comes to mind—the content of people's thoughts. But recent research shows that metacognitive experiences accompanying thinking, like a sense of the ease or difficulty with which information comes to mind, qualify the conclusions that people derive from thought content. The case of hindsight bias and attempts to remove that bias (debiasing) illustrate this. After an event outcome is known, people display hindsight bias by exaggerating its inevitability, believing they "knew it all along." The magnitude of hindsight bias varies with the ease or difficulty that known or alternative outcomes come to mind; the usually observed hindsight bias may even reverse when outcomes are difficult to bring to mind or increase when alternatives are difficult to bring to mind. Implications of metacognitive experiences can extend to other biases and their debiasing, as well as to how people make sense of the past more generally.     

系列项目时间和空间信息学习的分组效应研究

运用顺序回忆方法考察分组对系列项目时间和空间信息学习的影响。包括两个实验,实验一考察简化时间上的分组,或事先告知被试分组规则的情况下,分组是否会有助于时间顺序信息的学习。结果发现,这两个操作对时间顺序信息学习的促进作用不显著。实验二考察了垂直维度上不同形式的分组对空间位置信息学习的影响。结果发现,不同的分组方式对空间位置信息学习所起的作用不同。本研究支持了时间和空间两类顺序信息学习的内在过程不同,不应该用同一理论机制进行解释。     

视觉加工速度、瞬间信息整合特征与汉语学习困难

采用因素实验设计,通过与正常学生与听力损伤学生对比实验研究,探讨汉语学习困难学生视觉加工速度和视觉瞬间信息整合的特征。结果表明:(1)汉语学习困难学生存在基本视觉加工速度不足以及汉语语言文字视觉加工的特异性困难;(2)汉语学习困难学生需要更长时间整合瞬间视觉信息,从而影响了其加工的速度;(3)适当延长视觉刺激整合的时间,可以有效提高其视觉加工的效率。这些结果对改善学生的汉语学习困难具有一定的指导意义。     

语义启动效应的脑机制研究综述

文章主要介绍了语义启动的过程及其脑机制的研究进展。启动效应是内隐记忆的研究焦点,而语义启动是通过刺激的语义特征来研究启动效应的。语义启动的脑机制研究一般是通过脑损伤、脑成像和ERPs等方法实现的。研究表明,大脑的广泛区域都参与着语义启动过程,尤其是脑前区和大脑的左半球。     

Waiting impulsivity: a distinctive feature of ADHD neuropsychology?

Impulsivity is a core feature of attention-deficit hyperactivity disorder (ADHD). It has been conceptualized in a number of different ways. In the current article, we examine how the new concept of “waiting impulsivity”, which refers to premature responding before a scheduled target appears, adds to our understanding of impulsivity in ADHD. Sixty children (8–12 years old; 30 ADHD; 30 typically developing controls) completed the 4-choice serial reaction time task, a measure of waiting impulsivity, alongside tasks measuring inhibitory control and temporal discounting and questionnaires measuring behavioral disorder symptoms, delay aversion, and various aspects of impulsivity. A multiple logistic regression model was used to explore the contribution of the primary task outcomes to predict group membership. Children with ADHD displayed more waiting impulsivity and less inhibitory control; they did not differ in temporal discounting. There was no correlation between waiting impulsivity and inhibitory control. Waiting impulsivity was correlated with parent-reported ratings of hyperactivity/impulsivity, inattention, oppositional defiant disorder (ODD), and conduct disorder (CD) and with self-reported delay aversion ratings. Only waiting impulsivity was a significant predictor of ADHD status. In conclusion, waiting impulsivity is distinct from inhibitory control deficits and predicts ADHD status independently of it. Future research needs to examine the relationship with delay aversion and ODD/CD more thoroughly.     

Planning for Multiple Shopping Goals in the Marketplace

Four online grocery‐shopping experiments and one field study using video‐tracking technology at a grocery store document how shoppers’ motivation evolves from the beginning to the end of their shopping trips. We uncover unique motivational patterns as shoppers achieve multiple subgoals (i.e., choose multiple grocery items) to complete their trips: a monotonic decrease in motivation for shoppers with a shopping list versus a curvilinear trend (i.e., decrease then increase) in motivation for shoppers without a list. In addition, we demonstrate how to reverse the observed patterns for shoppers with a list by changing their reference points for tracking progress. The discovery of the moderating role of shopping‐list usage adds to the bubbling dialogue in goal pursuit and shopper psychology research concerning how consumer motivation follows either a monotonic trend (e.g., a goal gradient effect) or a nonmonotonic trend (e.g., the stuck‐in‐the‐middle effect). Importantly, we demonstrate how the stuck‐in‐the‐middle theory, which applies to single‐goal pursuits, can apply more broadly to the domain of grocery shopping, which consists of the generation and completion of multiple subgoals.     

助推目标实现：时间标记的动力效应

时间标记是指日常生活中所有突出的独特性事件。个体在经历当下的时间标记或期待未来的时间标记时, 其追求目标的动机水平得到提高, 并表现出更多的目标相关行为, 即时间标记具有一种动力效应。时间标记可能增加了个体对不同时间自我之间的分离感, 继而通过自我效能感、保持一致的自我形象、损失规避及缩小差距等心理过程提高追求目标的动机。未来研究应进一步探讨时间标记在动力效应中的角色定位及动力效应的持续时间、探究时间标记动力效应的普适性、检验可能的心理机制并在实践领域开展时间标记助推行为决策的应用研究。     

Revisiting interreligious relations: The convergence of global context and ecclesial developments

Following the important work of the 1980s and 1990s by the US churches and ecumenical bodies in developing interfaith statements and policies, significant events in both the US and international arenas were coincidental and motivational for US Christians to reconsider their interreligious engagement in a new context. This article examines the major contextual factors, as well as ecumenical developments with particular attention to the United Church of Christ and the National Council of Churches, which also will consider new statements in 2019.     

语言理解中语义整合的神经机制

语义整合是语言阅读理解中非常重要的环节。随着认知神经科学技术的广泛应用,当前关于语义整合的研究取得了长足进步,各种模型层出不穷。但是不同模型对于语义整合的功能定位及其内在机制却存在较大的争议。本文首先介绍当前关于语义整合的主要模型,然后对当前不同理论模型之间关于语义整合的界定,以及语义整合的功能定位是在额下回还是颞叶的争论进行了分析。我们认为,关于语义整合的实质、语义整合的功能网络将是未来研究的主要方向,相关的研究对于语言理解理论的发展将具有重要的启示。     

Decidable Cases of First-order Temporal Logic with Functions

We consider the decision problem for cases of first-order temporal logic with function symbols and without equality. The monadic monodic fragment with flexible functions can be decided with EXPSPACE-complete complexity. A single rigid function is sufficient to make the logic not recursively enumerable. However, the monadic monodic fragment with rigid functions, where no two distinct terms have variables bound by the same quantifier, is decidable and EXPSPACE-complete. Presented by Robert Goldblatt
