Incidental learning of trust from eye-gaze: Effects of race and facial trustworthiness

Humans rapidly make inferences about individuals’ trustworthiness on the basis of their facial features and perceived group membership. We examine whether incidental learning about trust from shifts in gaze direction is influenced by these facial features. To do so, we examined two types of face category: the race of the face and the initial trustworthiness of the face based on physical appearance. We find that cueing of attention by eye-gaze is unaffected by race or initial levels of trust, whereas incidental learning of trust from gaze behaviour is selectively influenced. That is, learning of trust is reduced for other-race faces, as predicted by reduced abilities to identify members of other races (Experiment 1). In contrast, converging findings from an independently gathered set of data showed that the initial trustworthiness of faces did not influence learning of trust (Experiment 2). These results show that learning about the behaviour of other-race faces is poorer than for own-race faces, but that this cannot be explained by differences in the perceived trustworthiness of different groups.     

The effect of perspective-taking on reasoning about strong and weak belief-relevant arguments

This study investigated whether perspective-taking reduces belief bias independently of argument strength. Belief bias occurs when individuals evaluate belief-consistent arguments more favourably than belief-inconsistent arguments. Undergraduates (n = 93) read arguments that varied with respect to belief-consistency (i.e., belief-consistent or belief-inconsistent) and strength (i.e., strong or weak) about the topic of climate change. After participants read each argument, those in the perspective-taking condition rated the argument's strength from a perspective of a climate scientist and then from their own perspectives, whereas those in the no perspective-taking condition only rated the arguments from their own perspectives. Perspective-taking eliminated belief bias for weak arguments, but not for strong arguments. Theoretical and practical implications of the results are discussed, and directions for future research are provided.     

A pilot study examining the effects of priming headache illness schema on attentional engagement towards pain relief medication,in those with high and low medication treatment beliefs

Few studies have assessed the underlying theoretical components of the Common Sense Model. Past studies have found, through implicit priming, that coping strategies are embedded within illness schema. Our aim was to evaluate the effect priming ‘headache’ illness schema upon attentional engagement to pain relief medication and to examine the interaction with illness treatment beliefs. Attentional engagement to the pain relief medication (‘Paracetamol’) was assessed using a 2 (primed vs. control) × 2 (strong belief in medication efficacy vs. weak belief in medication efficacy) design. During a grammatical decision task (identifying verbs/non-verbs), participants were randomised to receive a headache prime or a control. Response latency to the target word, ‘Paracetamol’ was the dependent variable. ‘Paracetamol’ treatment beliefs were determined using the brief illness perception questionnaire. Sixty-three participants completed the experiment. There was a significant interaction between illness-primed vs. control and high vs. low treatment efficacy of Paracetamol (p < .001), suggesting an attentional disengagement effect to the coping strategy in illness-primed participants whom held stronger treatment beliefs regarding the efficacy of Paracetamol. In summary, implicit illness schema activation may simultaneously activate embedded coping strategies, which appears to be moderated by specific illness beliefs.     

Why are negative behaviours likely to be immediately invoked traits? The effects of valence and frequency on spontaneous trait inferences

People make trait inferences immediately when observing others’ behaviours. Previous studies reported that this spontaneous trait inference (STI) occurs more strongly from negative behaviours than from positive behaviours. However, what is responsible for this negativity bias in STI is unclear. In this study, two experiments investigated the effects of valence (an event's affective positivity or negativity) and frequency (how frequently the behaviour is observed in everyday life) on the occurrence of STI using an adapted version of a savings‐in‐relearning paradigm. Experiment 1 revealed that only valence affected the frequent occurrence of STI. In addition, the instructions to suppress impression formation or to focus attention on an actor's face made no difference to the results. In Experiment 2, the negativity bias in STIs was shown a week after exposure to the behavioural stimuli. These results suggest that the negativity bias in STIs occurs robustly, and the negative valence of observed behaviour is mostly responsible for the negativity bias in STI. The importance of immediate categorization of negative stimuli is discussed in terms of ecological priority.

羞怯儿童对模糊情绪面孔的知觉偏差

采用类别知觉情绪识别范式,考察高、低羞怯儿童对快乐-愤怒和快乐-悲伤模糊情绪面孔的知觉偏差和知觉敏感性。结果发现：（1）相对于低羞怯儿童,高羞怯儿童倾向于将快乐-愤怒模糊情绪面孔知觉为愤怒,将快乐-悲伤模糊情绪面孔知觉为悲伤;（2）两组儿童在快乐-愤怒、快乐-悲伤模糊情绪面孔类别界线处的斜率差异均不显著。研究表明高羞怯儿童具有敌意归因偏向和更高的悲伤共情反应,而对快乐-愤怒和快乐-悲伤表情的类别转变不敏感。     

New Methods for Comparing Groups

Abstract— A commonly used method for comparing groups of individuals is the analysis of variance (ANOVA) F test. When the assumptions underlying the derivation of this test are true, its power, meaning its probability of detecting true differences among the groups, competes well with all other methods that might be used. But when these assumptions are false, its power can be relatively low. Many new statistical methods have been proposed—ones that are aimed at achieving about the same amount of power when the assumptions of the F test are true but which have the potential of high power in situations where the F test performs poorly. A brief summary of some relevant issues and recent developments is provided. Some related issues are discussed and implications for future research are described.     

状态自恋与攻击行为——知觉到的威胁、愤怒情绪和敌意归因偏差的多重中介作用

采用2(自恋故事vs.中性故事)×2(威胁情境vs.表扬情境)的被试间设计对162名大学生的状态自恋与攻击行为的关系及其机制进行考察。结果发现:(1)与中性故事组相比,自恋故事能够显著激活被试的状态自恋水平;(2)与表扬情境相比,威胁情境中自恋激活组个体的攻击意向显著高于中性故事组,说明状态自恋激活能够显著增加个体的攻击行为;(3)状态自恋通过知觉到的威胁、愤怒情绪和敌意归因偏差间接预测攻击行为;(4)从总体上来说,知觉到的威胁既可显著直接预测攻击行为,也可通过愤怒情绪间接预测攻击行为。对自恋激活组,状态自恋可以通过影响愤怒情绪和敌意归因偏差间接影响攻击行为;对中性控制组来说,这种关系则不存在。本研究结果证实,状态自恋的激活能够显著增加个体面对消极反馈时攻击行为产生的认知情绪机制。     

视角在自我评价早期阶段的调节作用

在自我评价过程中存在着自我积极偏差。已有研究表明,采用第三人称视角进行反射性自我评价可以减少自我积极偏差,这种调节作用主要表现在自我评价的后期,而评价早期是否就受到视角采择的调节尚不清楚。为了探讨视角采择在自我评价早期对积极偏差的调节作用,采集并分析了被试以第一人称和第三人称视角分别对积极、消极特质形容词进行自我描述判断时的脑电时域、频域数据。结果发现,在第三人称视角下,加工消极词比积极词在额叶区域诱发了更大的P2 (120-200ms)波幅,在左侧内侧前额叶有更显著的激活;在Theta (3-6Hz)、以及Gamma (30-45Hz)节律上有显著高的能量增加,而Alpha (8-13Hz)节律则有显著高的能量降低。说明在自我评价的早期,人们更容易注意到以第三人称为视角的自我相关消极信息,即通过他人视角采择对自我积极偏差的调节在自我评价的早期阶段就已经发生了。
