个体攻击性对愤怒表情类别知觉的影响

探讨了个体攻击性对愤怒表情加工中反应偏向和敏感性的影响。使用愤怒、恐惧原型生成表情连续体作为实验材料, 采用类别知觉实验范式考察了高、低攻击个体识别和辨别愤怒-恐惧连续体的类别转折点和斜率。结果发现, 与低攻击个体相比, 高攻击个体识别愤怒-恐惧连续体类别界线处的曲线斜率更大; 高攻击个体具有类别界线向恐惧一端偏移的倾向, 但并没有达到统计显著。这表明, 高攻击个体不存在敌意归因偏向, 而是对愤怒和恐惧表情的转变具有更高的敏感性。     

Self-reported aggression and the perception of anger in facial expression photos

The author's purpose in this study was to assess the relationship between self-reported aggression and "seeing" anger in others. Eighty-four undergraduate participants completed a self-report questionnaire about their own aggression (i.e., aggressive attitude, verbal aggression, and physical aggression), as well as measures of resiliency and locus of control. They also responded to a series of photographs depicting facial expressions of happy, sad, angry, and fearful emotions. The results indicated that individuals reporting higher levels of overall aggression also misidentified anger from the facial expressions when this was not the emotion presented (errors of commission). No significant differences appeared among individuals reporting high and low levels of aggression in terms of underreporting anger (errors of omission). The author also found significant correlations among identification of anger from photographs, resiliency, and locus of control. The findings of the study have important implications for understanding the relationship between aggression and one's perception of anger in others.     

高低特质攻击个体对威胁面部表情识别的差异研究——来自ERP的证据

为揭示高特质攻击个体对愤怒、恐惧威胁面部表情识别的特点及其电生理机制，本研究采用Buss-Perry攻击问卷选取高低特质攻击个体26名和27名为被试，采用面孔识别范式对高低特质攻击个体识别威胁面部表情时的ERP差异进行研究。结果发现，在愤怒、恐惧表情上，高特质攻击组在N170成分的潜伏期都显著短于低特质攻击组；在愤怒、恐惧表情上，高特质攻击组在P200成分的波幅都显著高于低特质攻击组。这表明高特质攻击个体对愤怒、恐惧威胁面部表情的识别具有高度敏感性，这种敏感性体现在面部表情识别的早期和中期阶段，而非晚期阶段，即高特质攻击个体在早期的前注意阶段就对愤怒、恐惧威胁面部表情进行优先注意；在中期的注意阶段，高特质攻击个体可以很好地确认愤怒、恐惧威胁面部表情。     

内隐/外显不同水平攻击者的注意偏向：行为和ERP证据

通过行为实验（点探测）和ERP实验（情绪Stroop）两个实验任务,考察了内隐/外显不同水平攻击者的注意偏向及其脑机制。结果表明：高外显攻击者对愤怒面孔存在注意偏向;高外显攻击者在愤怒面孔上的N100波幅显著低于中性面孔,表明其注意分配和调节能力较弱;高外显攻击者较之低外显攻击者的P300波幅更小表明其存在注意等方面的认知加工缺陷,N400波幅更小表明其对愤怒面孔进行语义编码时加工更为流畅;外显攻击组与内隐攻击组在FCz和Cz电极点上不同。这为内隐/外显攻击二者有着独立结构提供了行为与认知神经科学的证据。     

Cooperative and competitive motives enhance perceptual sensitivity to angry and happy facial expressions

The interdependent motives of cooperation and competition are integral to adaptive social functioning. In three experiments, we provide novel evidence that both cooperation and competition goals enhance perceptual acuity for both angry and happy faces. Experiment 1 found that both cooperative and competitive motives improve perceivers?? ability to discriminate between genuine and deceptive smiles. Experiment 2 revealed that both cooperative and competitive motives improve perceivers?? perceptual sensitivity to subtle differences among happy and angry facial expressions. Finally, Experiment 3 found that the motivated increase in perceptual acuity for happy and angry expressions allows perceivers to overcome the effects of visual noise, relative to unmotivated control participants. Collectively, these results provide novel evidence that the interdependent motives of cooperation and competition can attune visual perception, accentuating the subjectively experienced signal strength of anger and happiness.     

Negative emotionality influences the effects of emotion on time perception

In this study I used a temporal bisection task to test if greater overestimation of time due to negative emotion is moderated by individual differences in negative emotionality. The effects of fearful facial expressions on time perception were also examined. After a training phase, participants estimated the duration of facial expressions (anger, happiness, fearfulness) and a neutral-baseline facial expression. In accordance to the operation of an arousal-based process, the duration of angry expressions was consistently overestimated relative to other expressions and the baseline condition. In support of a role for individual differences in negative emotionality on time perception, temporal bias due to angry and fearful expressions was positively correlated to individual differences in self-reported negative emotionality. The results are discussed in relation both to the literature on attentional bias to facial expressions in anxiety and fearfulness and also, to the hypothesis that angry expressions evoke a fear-specific response.     

Taking the fight out of people: Exploring how defeat modulates the automatic aggressive response to facial anger

Past studies indicate that angry facial expressions automatically activate an aggressive response, seeming to support the view that humans possess an inborn, automatic tendencies to aggress. However, the current authors drew on influential models from evolutionary game theory to suggest that experiences of defeat may modulate this tendency. To examine this, four experiments were conducted to explore how defeat may modulate this aggressive response. In each study, participants executed simulated fight or flight responses based a computerized opponent's facial expression. Across studies, participants were typically faster to initiate fight (than flight) responses against an angry opponent. Simply losing simulated fights (Experiment 1) or experiencing aversive, white noise following simulated losses (Experiment 2) did not eliminate this tendency. However, when aversive noise was specifically experienced after losing to an angry opponent, the automatic aggressive response was eliminated (Experiment 3). This result was directly replicated (Experiment 4). Thus, these studies isolate the cues which automatize submissive behavior and show that fighting experience can modulate even our automatic aggressive responses to others’ anger displays.     

拥挤感启动对威胁性表情识别知觉敏感性的影响

为了考察拥挤感启动对威胁性面部表情识别的影响,以28名大学生为被试,进行不同拥挤启动条件下的愤怒-中性和恐惧-中性表情识别任务。信号检测论分析发现,拥挤感启动降低了愤怒表情识别的辨别力,不影响其判断标准,也不影响恐惧表情识别的辨别力和判断标准;主观报告的愤怒表情强度在拥挤感启动条件下显著高于非拥挤条件,恐惧、中性表情强度则不受拥挤感启动的影响。结果表明,拥挤感启动使人们辨别愤怒表情的知觉敏感性下降。     

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。

Emotion differentiation moderates aggressive tendencies in angry people: A daily diary analysis

Anger is commonly associated with aggression. Inefficient anger-coping strategies increase negative affect and deplete the regulatory resources needed to control aggressive impulses. Factors linked with better emotion regulation may then weaken the relationship between anger and aggression. The current work explored one factor associated with emotion regulation-differentiating one's emotions into discrete categories-that may buffer angry people from aggression. Three diary studies (N = 628) tested the hypothesis that emotion differentiation would weaken the relationship between anger and aggression. In Study 1, participants high in emotion differentiation reported less daily aggressive tendencies when angry, compared to low differentiators. In Study 2, compared to low differentiators, high differentiators reported less frequent provocation in daily life and less daily aggression in response to being provoked and feeling intense anger. Study 3 showed that high daily emotional control mediated the interactive effect of emotion differentiation and anger on aggression. These results highlight the importance of considering how angry people differentiate their emotions in predicting their aggressive responses to anger.     

Attention and interpretation processes and trait anger experience,expression, and control

This study explored attention and interpretation biases in processing facial expressions as correlates of theoretically distinct self-reported anger experience, expression, and control. Non-selected undergraduate students (N?=?101) completed cognitive tasks measuring attention bias, interpretation bias, and Spielberger’s State-Trait Anger Expression Inventory (STAXI-2). Attention bias toward angry faces was associated with higher trait anger and anger expression and with lower anger control-in and anger control-out. The propensity to quickly interpret ambiguous faces as angry was associated with greater anger expression and its subcomponent of anger expression-out and with lower anger control-out. Interactions between attention and interpretation biases did not contribute to the prediction of any anger component suggesting that attention and interpretation biases may function as distinct mechanisms. Theoretical and possible clinical implications are discussed.     

Attentional biases for angry faces: Relationships to trait anger and anxiety

In two experiments selective attention to angry faces was investigated in relation to trait anger and anxiety. A pictorial emotional Stroop task comparing colour-naming latencies for neutral and angry faces was employed. In Experiment 1 using an unmasked task, individuals scoring high on trait anger showed an attentional bias for angry faces. In Experiment 2, unmasked and masked versions of the task were used. Individuals were selected on low and high trait anxiety, but there was no indication of a relation between attentional bias scores and anxiety. When individuals were subsequently reallocated to groups on the basis of trait anger scores, the high anger group showed an attentional bias for angry faces in the unmasked and the masked task. Results are discussed in relation to recent neurobiological findings from our laboratory, as reflecting an evolutionary-evolved, content-specific response to the facial expression of anger.     

Attentional Biases for Facial Expressions in Social Phobia: The Face-in-the-Crowd Paradigm

The present study examines the attentional bias hypothesis for individuals with generalised social phobia (GSPs). Socially phobic individuals were hypothesised to exhibit attentional bias towards threat stimuli relevant to interpersonal situations. This hypothesis was tested using the face-in-the-crowd paradigm. GSPs and nonanxious controls (NACs) detected an angry, happy, neutral, or disgust target face in a crowd of 12 distracter photographs. Results indicated that, compared to NACs, GSPs exhibited greater attentional biases for angry than for happy faces in a neutral crowd. GSPs were more slowed down in their performance by happy and angry versus neutral distracters; NACs did not exhibit such sensitivity to distracter type. Finally, GSPs were faster in detecting anger than disgust expressions; NACs detected both types of faces equally quickly. Implications of these findings for the maintenance of social phobia are discussed.     

Contrasting effects of a hot and a cool system in anger regulation on cooperative behaviours

Angry mood and aggression are strongly associated. However, it is not socially acceptable to express strong aggression. Non-cooperative behaviours might be another aspect of aggressive behaviour. The present study examines the expression of non-cooperative behaviours after angry mood induction. Eighty-five university students were randomly assigned to hot or cool focus recall of a past angry event. At baseline, trait aggression and rejection sensitivity were evaluated. Just before the recall task, participants' state of angry mood was measured by the Anger Mood Scale. Then they engaged in either hot or cool focus recall of a past rejection event. Immediately after the mood induction, angry mood was measured again. They were then instructed to play the Mixed Motive game with an unknown person. Participants in both groups became angrier after the mood induction. One-way analysis of covariance, controlling for trait anger and rejection sensitivity, showed that the hot-focus participants gave significantly fewer points to the other person than the cool-focus participants. Participants high on trait aggression sent more verbally aggressive messages. The findings suggest that non-cooperative behaviour is another form of anger related aggression and might be more socially important than overt aggression.     

Repeated short presentations of morphed facial expressions change recognition and evaluation of facial expressions

This study investigated whether sensitivity to and evaluation of facial expressions varied with repeated exposure to non-prototypical facial expressions for a short presentation time. A morphed facial expression was presented for 500 ms repeatedly, and participants were required to indicate whether each facial expression was happy or angry. We manipulated the distribution of presentations of the morphed facial expressions for each facial stimulus. Some of the individuals depicted in the facial stimuli expressed anger frequently (i.e., anger-prone individuals), while the others expressed happiness frequently (i.e., happiness-prone individuals). After being exposed to the faces of anger-prone individuals, the participants became less sensitive to those individuals’ angry faces. Further, after being exposed to the faces of happiness-prone individuals, the participants became less sensitive to those individuals’ happy faces. We also found a relative increase in the social desirability of happiness-prone individuals after exposure to the facial stimuli.     

Childhood maltreatment is associated with increased neural response to ambiguous threatening facial expressions in adulthood: Evidence from the late positive potential

Childhood maltreatment increases lifetime vulnerability for psychopathology. One proposed mechanism for this association is that early maltreatment increases vigilance for and attention to subtle threat cues, persisting outside of the environment in which maltreatment occurs. To test this possibility, the present study examined neural responses to ambiguous and nonambiguous threatening facial expressions in a sample of 25 adults reporting a history of low-to-moderate levels of abuse in childhood and 46 reporting no or low levels of childhood maltreatment. The measure of neural response used was the late positive potential (LPP), a neural marker of sustained attention to motivationally salient information that is sensitive to subtle variation in emotional content. Participants passively viewed angry–neutral and fearful–neutral face blends and rated emotional intensity for each face. In the maltreated group, as fearful faces increased in emotional intensity, the LPP similarly increased, suggesting increased sensitivity to subtle variation in threatening content. Moreover, the LPP at each level of emotional intensity was not related to current symptoms of anxiety and depression. However, contrary to our hypotheses, adults with a history of abuse did not rate angry or fearful faces as more threatening, nor did they exhibit a larger LPP to angry faces, compared to controls. These findings suggest that childhood maltreatment may be associated with increased sensitivity to ambiguous threatening information in adulthood.     

Anxiety and error monitoring: Increased error sensitivity or altered expectations?

This study tested the prediction that the error-related negativity (ERN), a physiological measure of error monitoring, would be enhanced in anxious individuals, particularly in conditions with threatening cues. Participants made gender judgments about faces whose expressions were either happy, angry, or neutral. Replicating prior studies, midline scalp negativities were greater following errors than following correct responses. In addition, state anxiety interacted with facial expression to predict ERN amplitudes. Counter to predictions, participants high in state anxiety displayed smaller ERNs for angry-face blocks and larger ERNs for happy-face blocks, compared to less anxious participants. These results are inconsistent with the simple notion that anxiety enhances error sensitivity globally. Rather, we interpret the findings within an expectancy violation framework, in which anxious participants have altered expectations for success and failure in the context of happy and angry facial cues, with greater ERN amplitudes when expectations are violated.     

The Relationship Between Attention,Interpretation, and Memory Bias During Facial Perception in Social Anxiety

Although cognitive theories suggest the interactive nature of information processing biases in contributing to social anxiety, most studies to date have investigated these biases in isolation. This study aimed at (a) testing the association between social anxiety and each of the threat-related cognitive biases: attention, interpretation, and memory bias; and (b) examining the relationship between these cognitive biases in facial perception. We recruited an unselected sample of 188 adult participants and measured their level of social anxiety and cognitive biases using faces displaying angry, disgusted, happy, and ambiguous versions of these expressions. All bias tasks were assessed with the same set of facial stimuli. Regression analyses showed that social anxiety symptoms significantly predicted attention avoidance and poorer sensitivity in recognizing threatening faces. Social anxiety was, however, unrelated to interpretation bias in our sample. Results of path analysis suggested that attention bias influenced memory bias indirectly through interpretation bias for angry but not disgusted faces. Our findings suggest that, regardless of social anxiety level, when individuals selectively oriented to faces displaying anger, the faces were interpreted to be more negative. This, in turn, predicted better memory for the angry faces. The results provided further empirical support for the combined cognitive bias hypothesis.     

Facial reactions to violent and comedy films: Association with callous–unemotional traits and impulsive aggression

The current study adds to prior research by investigating specific (happiness, sadness, surprise, disgust, anger and fear) and general (corrugator and zygomatic muscle activity) facial reactions to violent and comedy films among individuals with varying levels of callous–unemotional (CU) traits and impulsive aggression (IA). Participants at differential risk of CU traits and IA were selected from a sample of 1225 young adults. In Experiment 1, participants (N?=?82) facial expressions were recorded while they watched violent and comedy films. Video footage of participants' facial expressions was analysed using FaceReader, a facial coding software that classifies facial reactions. Findings suggested that individuals with elevated CU traits showed reduced facial reactions of sadness and disgust to violent films, indicating low empathic concern in response to victims' distress. In contrast, impulsive aggressors produced specifically more angry facial expressions when viewing violent and comedy films. In Experiment 2 (N?=?86), facial reactions were measured by monitoring facial electromyography activity. FaceReader findings were verified by the reduced facial electromyography at the corrugator, but not the zygomatic, muscle in response to violent films shown by individuals high in CU traits. Additional analysis suggested that sympathy to victims explained the association between CU traits and reduced facial reactions to violent films.
