Negative mood disrupts self- and reward-biases in perceptual matching

There are established effects of self- and reward-biases even on simple perceptual matching tasks [Sui, J., He, X., &; Humphreys, G. W. (2012). Perceptual effects of social salience: Evidence from self-prioritization effects on perceptual matching. Journal of Experimental Psychology, Human Perception and Performance, 38, 1105–1117]; however we know little about whether these biases can be modulated by particular interventions, and whether the biases then change in the same way. Here we assessed how the biases alter under conditions designed to induce negative mood. We had participants read a list of self-related negative or neutral mood statements [Velten, E. (1968). A laboratory task for induction of mood states. Behavior Research and Therapy, 6, 473–482] and also listen for 10?min to a passage of negative or neutral music, prior to carrying out perceptual matching with shapes associated to personal labels (self or stranger) or reward (£12 or £1). Responses to the self- and high-reward-associated shapes were selectively slower and less sensitive (d′) following the negative mood induction procedures, and the decrease in mood correlated with decreases in the reaction time bias across “high saliency” (self and high-reward) stimuli. We suggest that negative mood may decrease self- and reward-biases through reducing attention to salient external stimuli.     

内隐联想测验中他人重要性对自我心理表征的影响

联合采用联想匹配任务和内隐联想测验（IAT）任务，考察了自我—他人分类中的他人重要性对自我—高奖赏相似性的影响。研究将中性的几何图形与自我、不同重要性的他人（实验一为陌生人，实验二为朋友）建立联结，并将自我（暂时建立联结的图形）高奖赏联合任务与自我低奖赏联合任务下的反应差异（即IAT值）作为自我—高奖赏相似性的指标，结果表明：（1）联想匹配任务中自我和朋友以及自我和陌生人之间都存在显著的自我优势效应；（2）IAT任务中，自我和高奖赏只在他人为朋友的自我—他人分类判断时才具有相似性，而他人为陌生人时二者不具有相似性。这说明他人重要性改变了自我的心理表征。

The differential outcomes procedure can overcome self-bias in perceptual matching

There are biases in perceptual matching between shapes and labels referring to familiar others, compared with when the labels refer to unfamiliar people. We assessed whether these biases could be affected by differential feedback (using the differential outcomes procedure [DOP]) compared with when feedback is provided using a nondifferential outcomes procedure (NOP). Participants formed associations between simple geometric shapes and labels referring to people the participant did or did not know (self, best friend, other). Subsequently, the task was to match a label to one of two shapes shown on a trial. When feedback for correct responses was given following the NOP condition, matches were faster to known people (self and friend) compared with those to an unknown person (stranger). However, this advantage for known personal relations was eliminated when participants were given feedback for correct responses following the DOP condition. The data are consistent with prior work showing that the DOP can facilitate the learning of taxing associations (for the stranger stimuli relative to the familiar self and friend stimuli). In addition, the results suggest that the facilitated perceptual matching for stimuli associated to individuals known personally may reflect better individuation of the association between the shape stimulus and the label, a process enhanced by using a DOP for associations with unfamiliar people.     

The automatic and the expected self: separating self- and familiarity biases effects by manipulating stimulus probability

Attentional control over prepotent responses has previously been shown by manipulating the probability with which stimuli appear. Here, we examined whether prepotent responses to self-associated stimuli can be modulated by their frequency of occurrence. Participants were instructed to associate geometric shapes with the self, their mother, or a stranger before having to judge whether the sequential shape–label pairs matched or mismatched the instruction. The probability of the different shape–label pairs was varied. There was a robust advantage to self-related stimuli in all cases. Reducing the proportion of matched self pairs did not weaken performance with self-related stimuli, whereas reducing the frequency of either matched mother or stranger pairs hurt performance, relative to when the different match trials were equiprobable. In addition, while mother and stranger pairs jointly benefitted when they both occurred frequently, there were benefits only to self pairs when the frequency of self trials increased along with either mother or stranger trials. The results suggest that biases favoring self-related stimuli occur automatically, even when self-related stimuli have a low probability of occurrence, and that expectations to frequent, self-related stimuli operate in a relatively exclusive manner, minimizing biases to high-probability stimuli related to other people. In contrast, biases to high-familiarity stimuli (mother pairs) can be reduced when the items occur infrequently and they do not dominate expectations over other high-frequency stimuli.     

惩罚对学习时间分配中决策与绩效的影响*

学习时间分配中的学习决策及其如何影响后续学习绩效是学习心理研究的重要领域。但对惩罚学习条件下,学习者是如何调整学习策略的,以及这种调整与后续学习绩效之间的关系尚不明确。本研究发现,奖励和惩罚条件下,参与者都会更多地选择高分的项目进行学习。在学习时间分配上,奖励组和惩罚组都倾向于将时间更多地分配到困难和高分的项目。但惩罚条件下参与者对低分项目的选择比例显著低于奖励条件,这表明惩罚影响学习者的学习策略。而且惩罚条件也影响低分且容易项目的学习效率。有趣的是,奖励和惩罚虽然对学习策略产生影响,却对学习绩效影响不显著,这表明在不同的学习条件下,不同的学习策略可以获得相似的学习成绩。     

Some effects of task relevance and friendship on helping: You don't always help the one you like

It was hypothesized that being outperformed on a task that is relevant to one's self-definition is threatening to self-esteem, and that this threat is greater when one is outperformed by a friend rather than by a stranger. When another's performance threatens self-esteem, persons will be less likely to help the other by making the task easy. To test these hypotheses, 52 friendship pairs participated with strangers in a word identification task described either as a measure of important skills (high relevance) or as a game (low relevance). Participants chose clues for both a friend and a stranger to use in identifying target words. As predicted, they gave harder clues under high-relevance than under low-relevance conditions. Moreover, they gave harder clues to strangers than to friends under low-relevance conditions, but gave harder clues to friends than to strangers under high-relevance conditions.     

奖赏历史对自上而下注意控制的调节：促进还是干扰？

奖赏能够影响注意控制,但是关于奖赏历史对注意控制的影响还处于争论之中。本研究以大学生为被试,采用点探测范式,操作了奖赏历史和奖赏额度,考察了奖赏历史对自上而下注意控制的调节作用。实验一结果发现,有奖赏-无奖赏条件下前后阶段反应时无显著差异,无奖赏-有奖赏条件下有奖赏阶段的反应时显著短于无奖赏阶段。实验二操作了奖赏额度,结果与实验一一致。整个研究表明,奖赏历史促进自上而下注意控制,先前奖赏对随后自上而下注意控制产生持续促进效应。     

All Negative Moods Are Not Equal: Motivational Influences of Anxiety and Sadness on Decision Making

Affective states of the same valence may have distinct, yet predictable, influences on decision processes. Results from three experiments show that, in gambling decisions, as well as in job-selection decisions, sad individuals are biased in favor of high-risk/high-reward options, whereas anxious individuals are biased in favor of low-risk/low-reward options. We argue that these biases occur because anxiety and sadness convey distinct types of information to the decision-maker and prime different goals. While anxiety primes an implicit goal of uncertainty reduction, sadness primes an implicit goal of reward replacement. We offer that these motivational influences operate through an active process of feeling monitoring, whereby anxious or sad individuals think about the options and ask themselves, “What would I feel better about …?”     

Self-bias modulates saccadic control

We present novel data on the role of attention in eliciting enhanced processing of stimuli associated with self. Participants were required to make pro- or anti-saccades according to whether learned shape–label pairings matched or mismatched. When stimuli matched participants were required to make an anti-saccade, and when the stimuli mismatched a pro-saccade was required. We found that anti-saccades were difficult to make to stimuli associated with self when compared to stimuli associated with a friend and a stranger. In contrast, anti-saccades to friend-stimuli were easier to make than anti-saccades to stranger-stimuli. In addition, a correct anti-saccade to a self-associated stimulus disrupted subsequent pro-saccade trials, relative to when the preceding anti-saccade was made to other stimuli. The data indicate that self-associated stimuli provide a strong cue for explicit shifts of attention to them, and that correct anti-saccades to such stimuli demand high levels of inhibition (which carries over to subsequent pro-saccade trials). The self exerts an automatic draw on attention.     

自我信息对知觉选择中整体优先性的调控作用

已有研究表明个人重要信息调控高级认知加工过程, 如面孔识别、记忆、思维等。本研究的三项实验系统地测量了个人重要信息对知觉选择的影响。采用最近发展的自我连接学习范式, 让中性几何图形与不同人(自我、朋友、陌生人)建立联系; 图形-标签连接完成后, 以复合图形(局部小图形组成整体大图形)作为实验刺激, 被试完成整体/局部图形判断任务, 通过评估个体对具有不同社会意义图形(目标vs.分心物水平)的感知差异, 测量个人重要信息对知觉选择的调控作用。结果发现, 与他人相关图形相比, 自我相关图形作为分心物调控整体优先效应, 这种效应一致地发生在整体和局部水平上, 并且不受注意任务的影响。这些结果提示社会信息对认知的调控作用发生在视觉选择水平上。     

Personality modulation of (un)conscious processing: Novelty Seeking and performance following supraliminal and subliminal reward cues

This study provides evidence that personality traits associated with responsiveness to conscious reward cues also influence responsiveness to unconscious reward cues. Participants with low and high levels of Novelty Seeking (NS) performed updating tasks in which they could either gain 1 euro or 5 cents. Gains were presented either supraliminally or subliminally at the beginning of each trial. Results showed that low NS participants performed better in the high-reward than in the low-reward condition, whereas high NS participants' performance did not differ between reward conditions. Interestingly, we found that low NS participants performed significantly better when rewards were presented unconsciously, whereas high NS participants' performance did not differ whether reward cues were presented subliminally or supraliminally. Our findings highlight the necessity of taking personality into account in unconscious cognition research. They also suggest that individual differences might determine whether implicit and explicit motives have similar or complementary influences.     

社会距离对成败行为性别归因偏差的影响

在陌生人和熟人两种社会距离下,让被试对同、异性成败行为进行归因,考查性别归因偏差现象(对异性美化、对同性贬损的归因)在社会距离上的变化。结果发现:(1)对于成功行为:被试对陌生异性做出的美化归因(能力-运气)显著高于陌生同性,出现性别归因偏差;被试对同、异性好友做出的美化归因差异不显著。(2)对于失败行为:被试对陌生同、异性做出的美化归因(运气-能力)差异不显著;被试对异性好友做出的美化归因显著高于同性,出现性别归因偏差。结论:性别归因偏差,在远社会距离他人表现成功时出现,表现失败时消失;在近社会距离他人表现成功时消失,表现失败时出现。结合相关研究和进化理论对结果进行了讨论。     

Reward Allocation by Impartial Allocators to Friend or Stranger Co-workers under Equal and Unequal Ability and Performance

The effects of a relationship variable (friends, strangers), an ability variable (equal, unequal), and a performance variable (equal, unequal) were studied in 40 male and 40 female university students. Eight versions of a hypothetical vignette were prepared to manipulate the eight treatment combinations. After reading an assigned vignette, subjects were asked to allocate $90 between two stranger or friend co-workers. Among other effects, the Relationship by Ability by Performance interaction was significant. The stranger, unequal ability, unequal performance allocations to the lower ability co-worker were significantly higher than the stranger, equal ability, unequal performance allocations, and the stranger, unequal ability, unequal performance allocations were higher than the friends, unequal ability, unequal performance allocations; this difference approached significance (p < .06). The questionnaire data revealed that, despite having favored strangers, the impartial allocators expected strangers to be less satisfied with their distribution than friends with their distribution. In this study, impartial allocators tended to compensate strangers to a greater extent for low performance or ability than friends or, alternatively, were more likely to ignore performance and ability differences between strangers than between friends.     

Bystander Responses to Risk for Rape Perpetrated by a Friend,Acquaintance, or Stranger

This study explored bystander responses to risk for an alcohol-facilitated rape perpetrated by a friend, acquaintance, or stranger. Undergraduates (N = 331) were randomly assigned to read 1 of 3 scenarios in which an apparently sober male friend, acquaintance, or stranger leads an intoxicated woman into a bedroom. Participants completed self-report measures of intent to directly intervene and barriers to intervention. Compared to men, women reported greater intent to help the potential victim and fewer barriers to intervention. Participant gender moderated the effect of the bystander’s relationship with the potential perpetrator on intent to confront and responsibility to intervene. Men reported more confrontation and more responsibility to intervene when perpetrators were identified as either friends or acquaintances than strangers. In contrast, women reported more confrontation when perpetrators were identified as friends than either strangers or acquaintances. Bystander education programs that address specific barriers to intervening with strangers and acquaintances could promote more frequent bystander behavior.     

Multiple high-reward items can be prioritized in working memory but with greater vulnerability to interference

Emerging literature indicates that working memory and attention interact in determining what is retained over time, though the nature of this relationship and the impacts on performance across different task contexts remain to be mapped. In the present study, four experiments examined whether participants can prioritize one or more high-reward items within a four-item target array for the purposes of an immediate cued recall task, and the extent to which this mediates the disruptive impact of a postdisplay to-be-ignored suffix. All four experiments indicated that endogenous direction of attention toward high-reward items results in their improved recall. Furthermore, increasing the number of high-reward items from one to three (Experiments 1–3) produces no decline in recall performance for those items, while associating each item in an array with a different reward value results in correspondingly graded levels of recall performance (Experiment 4). These results suggest the ability to exert precise voluntary control in the prioritization of multiple targets. However, in line with recent outcomes drawn from serial visual memory, this endogenously driven focus on high-reward items results in greater susceptibility to exogenous suffix interference, relative to low-reward items. This contrasts with outcomes from cueing paradigms, indicating that different methods of attentional direction may not always result in equivalent outcomes on working memory performance.     

社会距离和性别对公平关注的影响

本研究使用单次匿名最后通牒博弈任务,采用2（性别: 男性, 女性）×3（社会距离: 自我决策, 替朋友决策, 替他人决策）×5（提议类型: 1/9, 2/8, 3/7, 4/6, 5/5）的混合实验设计,通过操作反应者的不同社会距离,考察资产分配情境下自我-他人决策的性别差异。研究结果发现：（1）相比于自我决策和替朋友决策,女性被试替他人决策时更愿意接受提议1/9,2/8和3/7,而提议4/6和5/5的接受率不受社会距离的影响;男性被试中社会距离和提议类型的交互作用不显著;（2）不平等提议的反应时随社会距离增加而逐渐降低,而平等提议的反应时不受社会距离的调节;（3）替他人决策时女性的接受阈限显著低于男性,而自我决策及替朋友决策时接受阈限不存在性别差异。     

Interest in entering helping activities and self-disclosure to three targets on the Jourard self-disclosure scale.

Jourard's 40-item Self-disclosure Questionnaire was administered to 50 students in a training and selection program for a quasi-counseling position and 52 randomly selected students. Subjects indicated past disclosures to three target persons, parents, best friend, and stranger. Results indicated: highest disclosures were reported to best friends, lowest to strangers; subjects interested in the quasi-counseling position reported more disclosure than subjects not interested in this position; females reported more disclosure than males only to strangers.     

"With a little help from my friends...": the role of co-witness relationship in susceptibility to misinformation

Inaccuracies in eyewitness accounts can occur when witnesses are exposed to post-event misinformation via discussion with a co-witness. The current study examined the role of co-witness relationship by comparing the memory performance of pairs of romantic couples, friends and previously unacquainted strangers with that of individuals. Ninety-six participants viewed an event and then discussed the witnessed event with a stranger, a romantic partner or a friend. One member of each pair saw a theft take place during the witnessed event. Individual group participants did not discuss the witnessed event with anyone. Results indicate that all co-witness dyads produced less accurate recall accounts than participants who did not interact with another witness. However, witnesses who were previously acquainted with their co-witness (either in a friendship or romantic relationship) were significantly more likely to report information obtained from their co-witness that they had not seen themselves. Prior acquaintance also led to an increased number of incorrect attributions of both guilt and innocence.     

人际距离调节自我-他人的神经表征：来自oFRN的证据

为考察人际距离对自我-他人表征的影响, 采用金钱博弈任务检测了在自己操作、观察朋友操作和观察陌生同学操作时的脑电成分反馈相关负波(FRN)。结果发现, 观察任务产生了类似于自我操作时输钱反馈的负偏向, 即观察者反馈负波(oFRN); 在观察条件下, 被试自评与朋友的亲近程度高于同学(p<0.001), 两者引起的oFRN达到边缘显著性水平(p = 0.062), 亲近程度与oFRN呈显著相关(p = 0.041)。前者说明自我和他人具有相似表征, 后者则反映了自我对他人信息表征的替代性体验可能受人际距离所调节。
