Emotional Valence Precedes Semantic Maturation of Words: A Longitudinal Computational Study of Early Verbal Emotional Anchoring

We present a longitudinal computational study on the connection between emotional and amodal word representations from a developmental perspective. In this study, children's and adult word representations were generated using the latent semantic analysis (LSA) vector space model and Word Maturity methodology. Some children's word representations were used to set a mapping function between amodal and emotional word representations with a neural network model using ratings from 9-year-old children. The neural network was trained and validated in the child semantic space. Then, the resulting neural network was tested with adult word representations using ratings from an adult data set. Samples of 1210 and 5315 words were used in the child and the adult semantic spaces, respectively. Results suggested that the emotional valence of words can be predicted from amodal vector representations even at the child stage, and accurate emotional propagation was found in the adult word vector representations. In this way, different propagative processes were observed in the adult semantic space. These findings highlight a potential mechanism for early verbal emotional anchoring. Moreover, different multiple linear regression and mixed-effect models revealed moderation effects for the performance of the longitudinal computational model. First, words with early maturation and subsequent semantic definition promoted emotional propagation. Second, an interaction effect between age of acquisition and abstractness was found to explain model performance. The theoretical and methodological implications are discussed.     

排名列表项目展示方式对于项目评价的极化效应

排名列表是帮助消费者快速识别品牌或产品优劣的手段。研究基于空间隐喻理论, 探究排名列表的不同展示方式(垂直vs水平)对消费者列表项目评价的极化影响及作用机制。通过5个实验发现: 消费者对于垂直排名列表相比水平排名列表中的项目具有更大的评价极化效应, 并且验证了项目感知差异在上述关系中的中介作用, 即垂直排名列表的评价极化效应是由个体较高的排名列表项目感知差异所驱动的。此外, 当属性可评估性较低时, 才会出现不同列表项目的评价极化效应; 相反, 当排名列表项目属性可评估性较高时, 该评价极化效应消失。     

Spontaneous inferential processing while reading interleaved expository texts enables learners to discover the underlying regularities

Recent studies on text sequencing found learning advantages of interleaving over blocking in terms of high‐level inferences. We conducted a 2 × 2 × 2 mixed factorial experiment with college students (n = 117) by manipulating text sequence (interleaved vs. blocked) and self‐questioning activity while reading (spontaneous vs. prompted) between subjects and testing delay (immediately vs. 1‐week delay) within subjects. Results revealed that students are spontaneously engaged in self‐questioning and inferential processing while reading an interleaved text. Students who were spontaneously engaged while reading an interleaved text outperformed their counterparts in all other conditions in the immediate and delayed test on comparative reasoning, inductive reasoning, and memorization of factual details. The learning advantages were mediated by inductive inferences made while reading an interleaved text. Results support the discriminative contrast view that readers are encouraged to discover the underlying regularities when differences and similarities among categories are accentuated by their juxtaposition.     

群际态度与群际信念:耦合还是分离?

群际态度是人们对于某一群体的喜欢或不喜欢,包括外显群际态度和内隐群际态度,它是一个群体对另一群体正负连续体的评价。群际信念是人们对某一群体特性的刻板印象。以往研究认为,群际态度和群际信念是耦合关系,相互影响,相倚存在。但群际态度和群际信念也存在分离性证据,即存在矛盾性和非统一性。为何形成耦合或者分离,文化定型论、群际态度补偿机制(低地位群体的创造策略、高地位群体的慷慨策略),以及认知差别等都成为调节性平衡点。探讨群际态度和群际信念的分离性关系和作用机制对于干预和消弭群际边界与群际冲突,缓和群际关系具有深远影响,可以支持其独立路径予以针对性干预方案。     

How to nudge drivers to reduce speed: The case of the left-digit effect

To decrease the negative consequences of a road crash, even a small reduction in driving speeds can make a significant difference. We examined the possible application of the left-digit effect as a nudge to reduce road speed. In the marketing field, this effect is based on reporting price tags that are characterized by a low leftmost number and a high rightmost number (e.g., a price tag of €14.99 rather than €15.00). We applied the same strategy to improve road safety. Participants were college students (43.75% female, mean age = 24.06 years in Study 1; 50% female, mean age = 23.53 years in Study 2) who were asked to drive in a simulator on a route that had both usual unmodified road signs (e.g., 50 km/h) and the same road signs increased or decreased by one unit (e.g., 49, 51 km/h). We compared the average median speeds in road segments with unmodified road signs with those in road segments with the corresponding modified signs. The average median speeds in the presence of a sign modified by the reduction of 1 km/h were significantly lower compared with the median average speeds recorded with unmodified signs. We showed that the application of psychological insights can reduce driving speeds and therefore increase road safety.     

工作记忆中的积极效应：情绪效价与任务相关性的影响

积极效应指相比于年轻人, 老年人更倾向于优先加工积极情绪刺激而非消极情绪刺激。近年来工作记忆的研究发现积极效应会受到情绪效价与任务相关性的影响：情绪效价作为任务相关属性的研究支持工作记忆中存在积极效应, 具体表现为老年人对积极情绪刺激记忆的增强, 以及对消极情绪刺激记忆的减弱; 情绪效价作为工作记忆任务无关属性的研究相对较少, 且未发现一致的积极效应, 提示情绪效价及任务相关性均为影响工作记忆积极效应的关键因素。脑成像的研究初步表明, 工作记忆中情绪加工上的年龄效应与背侧执行系统和腹侧情绪系统的随龄功能变化有关。社会情绪选择理论与双竞争模型对工作记忆中的积极效应具备较大的解释力, 而动态整合理论尚缺乏实证研究支持。未来研究可进一步探究老年人工作记忆不同阶段情绪加工的特点, 澄清不同情绪材料内在编码过程上的差异对积极效应发生机制的潜在影响, 探讨情绪效价及任务相关性影响工作记忆积极效应的关键神经环路, 并揭示情绪工作记忆训练提升老年人认知功能与情绪体验的内在机制及其潜在应用价值。     

知觉模糊度影响学习的延迟效应

基于迁移适当加工理论,采用连续识别任务范式,通过操纵字词和图片的模糊度来考察知觉模糊非流畅的延迟效应。结果发现：（1）模糊不流畅的材料学习判断值更低;（2） 知觉模糊程度对即时的再认成绩没有影响,但在延迟再认测试中流畅性较低的模糊材料成绩更好。该结果表明实验操纵方式所引发的编码过程和记忆测试所需的检索过程性质上相匹配,而且延迟测试时,知觉非流畅可以促进学习,说明该效应存在边界。     

直升机教养的内涵、影响和后效

直升机教养是父母对始成年期青少年普遍采用的一种教养方式,它是指父母给孩子过度的支持,较多地控制其行为,并不能给予孩子适合其年龄的自主权的教养方式。本文从直升机教养的概念辨析、影响因素和作用后效方面进行了系统梳理和整合分析,未来研究需要扩展研究对象和内容、精细探讨直升机教养的作用机制、重视我国始成年人的直升机教养,深入考察直升机教养与健康成长的因果关系。     

消极元刻板印象激活对老年人认知表现的影响

本研究以59名老年人为研究对象,采用N-back认知任务探讨在不同难度的认知负荷任务中老年人消极元刻板印象激活的认知效应。结果发现：1、消极元刻板印象激活组的正确率显著低于未激活组;高认知负荷任务组的正确率显著低于低认知负荷任务组。2、消极元刻板印象激活组的反应时显著长于未激活组;高认知负荷任务组的反应时显著长于低认知负荷任务组;组别与任务难度之间交互作用达到边缘显著,在低认知负荷任务中,消极元刻板印象激活组和未激活组的反应时差异不显著,在高认知负荷任务中,消极元刻板印象激活组的反应时显著长于未激活组。上述结果表明,老年人消极元刻板印象的激活导致了负面的认知效应。
