Reactive and proactive aggression: Similarities and differences

The purpose of the current study was to elaborate the nomological net surrounding the constructs of reactive (RA) and proactive aggression (PA). Typically examined in the context of children, the current study utilized a sample of 211 young adults to examine the relations between reactive and proactive aggression and measures of general personality and social information processing, as well as maladaptive behavioral correlates such as crime, substance use, and riskier sex. Both raw and residualized scores were examined. Using raw scores, the primary differences between RA and PA were related to Neuroticism (i.e., RA more strongly related) and externalizing behaviors (i.e., PA more strongly). The authors comment on the similarity of findings when using raw scores and the divergence of findings using residualized scores and argue for a cautious interpretation of differences based on residualized scores. The authors conclude that the role of Neuroticism warrants further exploration as a means for understanding the heterogeneity of aggressive behavior.     

简化的联合再认范式中情绪对错误记忆影响的年龄差异

以康奈尔情绪DRM词表为主要实验材料, 使用简化的联合再认范式(DRM范式的变式), 结合多项式加工树建模的统计手段, 对34名年轻人(23 ± 2岁)和28名老年人(68 ± 5岁)的再认记忆进行比较, 以考察不同年龄组中情绪效价对错误记忆的作用机制。结果发现材料的情绪效价对错误记忆的影响存在显著年龄差异：(1) 积极情绪能够有效降低老年人的错误记忆, 其作用机制为积极情绪增强了老年人的字面痕迹而减弱了要点痕迹提取; (2) 消极情绪能够有效地降低年轻人的错误记忆, 其作用机制为消极情绪使年轻人反应偏向降低, 但不影响其记忆痕迹的提取。结果表明, 简化的联合再认范式下, 情绪效价对错误记忆的效应存在明显的年龄差异：老年人表现出积极情绪降低错误记忆的积极偏向; 年轻人表现出消极情绪降低错误记忆的消极偏向; 情绪效应对错误记忆的认知机制存在年龄差异。     

工作记忆对知觉类别学习的影响:问题与构想

人们学习将感知到的客体按照不同的标准或规则分类存储,即类别学习。而工作记忆作为多种认知加工的基础,对类别学习具有重要作用。基于已有研究,分别梳理了言语工作记忆和视空工作记忆对基于规则和信息整合类别结构的影响。目前,执行功能是否影响内隐类别学习系统、工作记忆负荷对内隐外显类别学习系统的影响是否一致还存在争议。此外,工作记忆影响知觉类别学习的认知加工阶段尚不清晰。未来的研究还需明确工作记忆负荷对内隐和外显类别学习的影响,进一步验证工作记忆影响类别学习的认知加工阶段假设的合理性。     

时间距离对于验证性信息加工的影响

研究基于解释水平理论考察时间距离对于验证性信息加工的影响, 即在个体和组织决策情境中, 人们倾向于偏好选择和高估与自身观点和决策相一致的信息, 而不是非一致性信息。通过4个情境决策实验, 研究结果一致表明近期决策会提高信息搜寻和评估中的验证偏差, 而远期决策会降低它们的验证偏差, 知觉到的决策确定性在其中起到部分中介作用(实验1b)。解释水平(实验2)和期许性/可行性表征(实验3)分别在时间距离对验证性信息加工的影响中起到调节作用, 结果依次表明在低解释水平(高可行性-低期许性特征)条件下, 时间距离与验证性信息加工的负相关关系会得到显著增强, 而在高解释水平(高期许性-低可行性特征)条件下, 时间距离与验证性信息加工的负相关关系会得到显著降低。     

Sound symbolic naming of novel objects is a graded function

Although linguistic traditions of the last century assumed that there is no link between sound and meaning (i.e., arbitrariness), recent research has established a nonarbitrary relation between sound and meaning (i.e., sound symbolism). For example, some sounds (e.g., /u/ as in took) suggest bigness whereas others (e.g., /i/ as in tiny) suggest smallness. We tested whether sound symbolism only marks contrasts (e.g., small versus big things) or whether it marks object properties in a graded manner (e.g., small, medium, and large things). In two experiments, participants viewed novel objects (i.e., greebles) of varying size and chose the most appropriate name for each object from a list of visually or auditorily presented nonwords that varied incrementally in the number of “large” and “small” phonemes. For instance, “wodolo” contains all large-sounding phonemes, whereas “kitete” contains all small-sounding phonemes. Participants' choices revealed a graded relationship between sound and size: The size of the object linearly predicted the number of large-sounding phonemes in its preferred name. That is, small, medium, and large objects elicited names with increasing numbers of large-sounding phonemes. The results are discussed in relation to cross-modal processing, gesture, and vocal pitch.     

Face recognition as a predictor of social cognitive ability: Effects of emotion and race on face processing

The human face conveys important social signals when people interact in social contexts. The current study investigated the relationship between face recognition and emotional intelligence, and how societal factors of emotion and race influence people's face recognition. Participants’ recognition accuracy, reaction time, sensitivity, and response bias were measured to examine their face‐processing ability. Fifty Caucasian undergraduates (38 females, 12 males; average age = 21.76 years) participated in a face recognition task in which they discriminated previously presented target faces from novel distractor faces. A positive correlation between participants’ emotional intelligence scores and their performance on the face recognition task was observed, suggesting that face recognition ability was associated with emotional or social intelligence. Additionally, Caucasian participants recognized happy faces better than angry or neutral faces. It was also observed that people recognized Asian faces better than Caucasian ones, which appears to be contradictory to the classic other‐race effect. The present study suggests that some societal factors could influence face processing, and face recognition ability could in turn predict social intelligence.     

中央凹加工负荷与副中央凹信息在汉语阅读眼跳目标选择中的作用

研究探讨汉语读者选择眼跳目标时, 中央凹注视词的加工负荷是否影响副中央凹获取信息量, 进而调节随后的眼跳长度。采用眼动追踪技术, 操纵了中央凹注视词的词频(高频、低频)和副中央凹词的笔画数(多笔画、少笔画)。结果发现：从中央凹词到副中央凹少笔画词的眼跳长度显著地长于到多笔画词的, 且这种笔画数效应并不受中央凹加工负荷的调节; 从高频中央凹词到副中央凹词的眼跳长度显著地长于低频词的。在本实验条件下结果提示：中央凹加工负荷在眼跳目标选择中的作用不是通过调节副中央凹获取信息量的多少来实现的。     

面孔空想性错视及其神经机制

面孔空想性错视, 是指在不存在面孔的物体或抽象图案上看到面孔, 例如在月球表面看到面孔。它受到自下而上信息与自上而下加工的共同影响。近年来, 研究者通过行为实验、事件相关电位技术以及脑成像技术对不同的空想性错视影响因素进行研究。结果发现, 面孔空想性错视的产生取决于刺激是否包含类似面孔结构, 内部面孔模板是否能与当前刺激匹配, 以及有无面孔相关背景。同时也受到个体差异与情绪状态影响。脑成像研究发现, 在发生空想性错视时, 来自额叶区与枕叶视觉区的信息会在FFA进行整合。未来研究可以致力于探索面孔空想性错视中个体差异的行为与神经机制, 以及不同类型的自上而下调节之间的相互影响及其神经机制。
