高社交焦虑个体对正性面孔的解释偏差

本研究采用情绪启动范式考察社交焦虑个体对正性刺激解释偏差。研究以正性和打碎的面孔为启动项,正性或负性非社交词为目标项,要求高社交焦虑组被试和控制组被试判断目标项的情感色彩,并记录其反应时与准确率。结果发现,两组被试具有不同的情绪启动模式：高焦虑组被试未表现出显著地相容性效应;他们在正性-正性条件下的反应时显著慢于控制组被试。研究结果提示高社交焦虑个体具有对正性社交刺激的解释偏差,他们不能充分理解正性社交刺激的积极含义。     

Impaired positive inferential bias in social phobia

People with social phobia report anticipatory and retrospective judgments about social situations that appear consistent with a negative interpretative bias. However, it is not at all clear that biased interpretative inferences are made "on-line;" that is, at the time that ambiguous information is first encountered. In a previous study, volunteers who were anxious about interviews were found to lack the positive on-line inferential bias that was characteristic of nonanxious controls but also failed to show a bias favoring threatening inferences (C. R. Hirsch & A. Mathews, 1997). This finding was confirmed in the present study, in which social phobic patients showed no evidence of making on-line emotional inferences, in contrast with socially nonanxious controls who were again clearly biased in favor of positive inferences. The authors concluded that nonanxious individuals are characterized by a benign on-line inferential bias, but that this is impaired in people with social phobia.     

In the absence of rose-colored glasses: Ratings of self-attributes and their differential certainty and importance across multiple dimensions in social phobia

Sixty-seven individuals with social phobia (social anxiety disorder) and 60 healthy controls rated their perceived standing relative to others on 13 self-attribute dimensions, their level of certainty concerning those standings, and the importance of each dimension. As expected, individuals with social phobia provided self-ratings that were significantly more negative than controls across all dimensions. In addition, positive self-views were equated with higher levels of certainty and importance for controls, but not for individuals with social phobia. Thus, whereas reports of control participants reflected a healthy, positive framing of self-views, the ratings of clinical participants demonstrated an orientation toward self-framing that was neither positive nor negative. Together, these novel findings shed light on the nature of self-appraisals in social anxiety. Implications of these results are discussed in terms of contemporary cognitive-behavioral models of social phobia.     

Biased allocation of faces to social categories

Three studies show that social categorization is biased at the level of category allocation. In all studies, participants categorized faces. In Studies 1 and 2, participants overallocated faces with criminal features--a stereotypical negative trait--to the stigmatized Moroccan category, especially if they were prejudiced. On the contrary, the stereotype-irrelevant negative trait stupid did not lead to overallocation to the Moroccan category. In Study 3, using the stigmatized category homosexual, the previously used negative trait criminal--irrelevant to the homosexual stereotype--did not lead to overallocation, but the stereotype-relevant positive trait femininity did. These results demonstrate that normative fit is higher for faces with stereotype-relevant features regardless of valence. Moreover, individual differences in implicit prejudice predicted the extent to which stereotype-relevant traits elicited overallocation: Whereas more negatively prejudiced people showed greater overallocation of faces associated with negative stereotype-relevant traits, they showed less overallocation of faces associated with positive stereotype-relevant traits. These results support our normative fit hypothesis: In general, normative fit is better for faces with stereotypical features. Moreover, normative fit is enhanced for prejudiced individuals when these features are evaluatively congruent. Social categorization thus may be biased in itself.     

Interpretation of facial expressions and social anxiety: Specificity and source of biases

Cognitive-behavioural models of social phobia (Clark & Wells, 1995; Rapee & Heimberg, 1997) propose that biased information processing contributes to the maintenance of social phobia. Given the importance of facial expressions in social interactions, recent investigations of these information-processing biases have increasingly used facial stimuli. The current study utilised schematic faces of emotional expressions to investigate interpretations of facial expressions and specific facial features in individuals with high and low social anxiety. Individuals with elevated social anxiety demonstrated biases in their perceptions of negative valence from the faces, whereas group differences were not observed for perceptions of activity or potency. Further, although the two groups generally utilised the same facial features to interpret facial expressions, the results suggested that individuals with high social anxiety may be more lenient in perceiving threat in faces than individuals without social anxiety.     

Can I trust you? Negative affective priming influences social judgments in schizophrenia

Successful social interactions rely on the ability to make accurate judgments based on social cues as well as the ability to control the influence of internal or external affective information on those judgments. Prior research suggests that individuals with schizophrenia misinterpret social stimuli and this misinterpretation contributes to impaired social functioning. We tested the hypothesis that for people with schizophrenia, social judgments are abnormally influenced by affective information. Twenty-three patients with schizophrenia and 35 healthy control participants rated the trustworthiness of faces following the presentation of neutral, negative (threat-related), or positive affective primes. Results showed that all participants rated faces following negative affective primes as less trustworthy than faces following neutral or positive primes. Importantly, this effect was significantly more pronounced for participants with schizophrenia, suggesting that schizophrenia may be characterized by an exaggerated influence of negative affective information on social judgment. Furthermore, the extent that the negative affective prime influenced trustworthiness judgments was significantly associated with patients' severity of positive symptoms, particularly feelings of persecution. These findings suggest that for people with schizophrenia, negative affective information contributes to an interpretive bias, consistent with paranoid ideation, when judging the trustworthiness of others. This bias may contribute to social impairments in schizophrenia.     

Forced choice reaction time paradigm in children with separation anxiety disorder, social phobia, and nonanxious controls

Cognitive distortions refer to cognitive processes that are biased and therefore yield dysfunctional and maladaptive products (e.g., interpretation bias). Automatic aspects of information processing need to be considered and investigating these aspects requires forms of assessment other than self-report. Studies focussing on the specificity of cognitive biases across different types of anxiety disorders in childhood are rare. Thus, a forced choice reaction time paradigm with picture stimuli was used to assess the interpretation bias in anxious children online. The study investigated disorder-specific interpretation bias in 71 children with separation anxiety disorder (SAD), 31 children with social phobia, and 42 children without mental disorders, aged 5–13 years. Results indicated that children with SAD rated ambiguous separation pictures as significantly more unpleasant and more arousing than nonanxious children. However, no support was found that children with SAD and social phobia interpret ambiguous separation or social pictures in a more negative way than nonanxious children. Furthermore, no group differences were found in reaction times to all picture categories.     

Lack of an Attention Bias Away From Relatively Negative Faces in Dysphoria Is Not Related to Biased Emotion Identification

Eye-tracking-based attention research has consistently shown a lack of a normative attentional bias away from dysphoric face stimuli in depression, characterizing the attention system of non-depressed individuals. However, this more equal attention allocation pattern could also be related to biased emotion identification, namely, an inclination of depressed individuals to attribute negative emotions to non-negative stimuli when processing mood-congruent stimuli. Here, we examined emotion identification as a possible mechanism associated with attention allocation when processing emotional faces in depression. Attention allocation and emotion identification of participants with high (HD; n = 30) and low (LD; n = 30) levels of depression symptoms were assessed using two corresponding tasks previously shown to yield significant findings in depression, using the same face stimuli (sad, happy, and neutral faces) across both tasks. We examined group differences on each task and possible between-task associations. Results showed that while LD participants dwelled longer on relatively positive faces compared with relatively negative faces on the attention allocation task, HD participants showed no such bias, dwelling equally on both. Trait anxiety did not affect these results. No group differences were noted for emotion identification, and no between-task associations emerged. Present results suggest that depression is characterized by a lack of a general attention bias toward relatively positive faces over relatively negative faces, which is not related to a corresponding bias in emotion identification.     

Understanding associations between negatively biased attention and depression and social anxiety: positively biased attention is key

ABSTRACT

Background and objectives: Although research supports the premise that depressed and socially anxious individuals direct attention preferentially toward negative emotional cues, little is known about how attention to positive emotional cues might modulate this negative attention bias risk process. The purpose of this study was to determine if associations between attention biases to sad and angry faces and depression and social anxiety symptoms, respectively, would be strongest in individuals who also show biased attention away from happy faces.

Methods: Young adults (N?=?151; 79% female; M?=?19.63 years) completed self-report measures of depression and social anxiety symptoms and a dot probe task to assess attention biases to happy, sad, and angry facial expressions.

Results: Attention bias to happy faces moderated associations between attention to negatively valenced faces and psychopathology symptoms. However, attention bias toward sad faces was positively and significantly related to depression symptoms only for individuals who also selectively attended toward happy faces. Similarly, attention bias toward angry faces was positively and significantly associated with social anxiety symptoms only for individuals who also selectively attended toward happy faces.

Conclusions: These findings suggest that individuals with high levels of depression or social anxiety symptoms attend preferentially to emotional stimuli across valences.     

Self-perception and rumination in social anxiety

The present study examined the relationship between perceptions of performance and post-event processing (PEP) following task feedback in individuals with social phobia and matched control participants. Groups of high and low socially anxious participants engaged in a structured 5-min conversation in groups of four people. Following the conversation, false feedback (given in the form of either high scores or moderate scores) was given and self-appraisals of performance, levels of positive and negative mood, and levels of PEP were assessed. Results showed that participants' perceptions of their own performance and levels of positive affect significantly predicted the degree to which they engaged in negative rumination about the task. The moderate score condition was found to be detrimental for socially anxious individuals' self-appraisals and PEP, whereas controls showed no significant difference in self-appraisal and PEP, regardless of feedback. The results are discussed in relation to current cognitive models of social phobia and both treatment implications and directions for future research are explored.     

Social phobics do not misinterpret facial expression of emotion

Attentional biases in the processing of threatening facial expressions in social anxiety are well documented. It is generally assumed that these attentional biases originate in an evaluative bias: socially threatening information would be evaluated more negatively by socially anxious individuals. However, three studies have failed to evidence a negative evaluative bias in the processing of emotional facial expression (EFE) in socially anxious individuals. These studies however suffer from several methodological limitations that the present study has attempted to overcome. Twenty-one out-patients diagnosed with generalized social phobia have been compared to 20 out-patients diagnosed with another anxiety disorder and with 39 normal controls matched for gender, age and level of education. They had to decode on seven emotion intensity scales a set of 40 EFE whose intensity and emotional nature were manipulated. Although sufficient statistical power was ensured, no differences among groups could be found in terms of decoding accuracy, attributed emotion intensity, or reported difficulty of the task. Based on these findings as well as on other evidences, we propose that, if they exist, evaluative biases in social anxiety should be implicit and automatic and that they might be determined by the relevance of the stimulus to the person's concern rather than by the stimulus valence. The implications of these findings for the interpersonal processes involved in social phobia are discussed.     

Attentional bias for words and faces in social anxiety

Conflicting findings concerning the nature and presence of attentional bias in social anxiety and social phobia have been reported in the literature. This paper reports the findings of two studies comparing people with high and low social anxiety on dot probe tasks using words, faces photographed in front view, and faces photographed in profile as stimuli. In Study 1 those with high social anxiety displayed an attentional bias towards negative faces. The low social anxiety group showed an attentional bias towards positive faces. No significant effects were observed on the dot probe using words as stimuli. Study 2 used pairs of faces presented in profile as though looking at each other. One of the faces displayed either a positive, negative or neutral expression. The second face always had a neutral expression, and in half of the trials it was the subject's own face. The findings of this more ecologically valid procedure replicated those of Study 1. Facilitated attention to dots following emotional faces was specific to threatening facial stimuli. From these studies it appears that the facial dot probe task is a more sensitive index of attentional bias than the word task in a non-clinical sample with social anxiety.     

Attentional biases to internal and external sources of potential threat in social anxiety

D. M. Clark and A. Wells (1995) proposed that a shift of attention inward toward interoceptive information is a central feature of social phobia. However, few studies have examined attentional biases toward internal physiological cues in social phobia. The current experiment assessed whether socially anxious individuals exhibit an attentional bias (a) toward cues for an internal source of potential threat (heart-rate information), (b) toward cues for an external source of potential threat (threatening faces) or (c) both. Ninety-one participants who were selected to form extreme groups based on a social anxiety screening measure performed a dot-probe task to assess location of attention. Results showed that socially anxious participants exhibited an attentional bias toward cues of internal, but not external, sources of potential threat.     

Patients with generalized social phobia direct their attention away from faces

The experiment tested whether patients with social phobia direct their attention to or away from faces with a range of emotional expressions. A modified dot probe paradigm (J. Abnorm. Psychol. 95 (1986) 15) measured whether participants attended more to faces or to household objects. Twenty patients with social phobia were faster in identifying the probe when it occurred in the location of the household objects, regardless of whether the facial expressions were positive, neutral, or negative. In contrast, controls did not exhibit an attentional preference. The results are in line with recent theories of social phobia that emphasize the role of reduced processing of external social cues in maintaining social anxiety.     

阈下抑郁个体对负性情绪刺激的注意解脱困难

本研究拟采用点探测范式及不同情绪内容的面孔刺激（高兴、中性、悲伤和愤怒）考察阈下抑郁个体的负性注意偏向及其内在机制。点探测任务中情绪面孔配对呈现（负性-中性、正性-中性）,配对面孔中的情绪线索位置与靶刺激的位置构成负性一致/不一致和正性一致/不一致条件,同时实验中加入“中性-中性”面孔线索作为一致和不一致条件的对比基线来考察注意偏向的内在机制。结果发现,阈下抑郁个体在负性不一致条件下的反应时显著长于负性一致条件,表明阈下抑郁个体具有对负性刺激的注意偏向;进一步比较发现,阈下抑郁个体在负性不一致条件下的反应时显著的长于“中性-中性”基线条件,而负性一致条件与基线之间差异不显著,表明阈下抑郁个体的负性注意偏向为对负性刺激的注意解脱困难。结果另发现,阈下抑郁个体未能像无抑郁对照组个体表现出对正性刺激的注意偏向。结果表明,处于阈下抑郁状态的个体表现出对负性刺激的注意偏向,具体为对负性刺激的注意解脱困难,其原因可能是由于阈下抑郁个体在注意控制和情绪调节功能上的紊乱。     

Non-specific encoding of threat in social phobia and panic disorder

This study employs a release of proactive interference technique to explore encoding-related processes in social phobia. Twenty-six individuals with social phobia and 24 individuals with panic disorder participated in the memory task. Significant release of proactive interference was found when neutral and threat dimensions were encoded, but not when social and physical threat dimensions, or when positive and threat dimensions were presented. Threat was therefore differently encoded depending on the active encoding context in which semantic processing occurred. Individuals with social phobia or panic disorder did not differ in the release of proactive interference. The present experiment consequently yields little support for the specificity hypothesis in memory of anxious individuals. Instead, the findings generally demonstrate that threat encoding is similar for people with social phobia and those with panic disorder.     

Social anxiety and interpersonal perception: a social relations model analysis

Cognitive models of social phobia posit that an individual's negative beliefs about the way he or she is perceived by others (metaperceptions) are a core feature of the disorder. The social relations model () was used to analyze interpersonal perception data collected following unstructured social interactions in 62 socially anxious (SA) and 62 not socially anxious (NSA) individuals. Using this model, the interpersonal perceptions were analyzed to evaluate whether pathological levels of social anxiety are associated with self-perceptions, metaperceptions, and perceptions from others. SA participants saw themselves negatively and believed others saw them negatively. Although seen as more nervous by others, SA participants were not seen as less likeable. A mediational model demonstrated that the negative metaperceptions of SA individuals were more a function of their own self-perceptions than the negative perceptions of others. These findings were not attributable to depressive symptoms. Implications for theory and treatment of social phobia are discussed.     

Social anxiety and the effects of negative self-imagery on emotion, cognition, and post-event processing

Numerous studies have shown that social phobia patients experience negative self-impressions or images during social situations. Clark and Wells (1995) posited that such negative self-images are involved in the maintenance of social phobia. Thus, the present study investigated the effects of negative self-imagery on cognition and emotion during and following a brief social situation. Specifically, high and low socially anxious participants (N = 77) were instructed to hold either a negative or control self-image as they engaged in a brief speech. Participants then rated their anxiety, performance, cognitions, and focus of attention. Twenty-four hours later, they returned to the laboratory and completed questionnaires assessing the amount of post-event processing (PEP) they engaged in. The results showed that, irrespective of the level of social anxiety or depressive symptoms, participants that held the negative self-image experienced higher levels of anxiety, were more self-focused, experienced more negative thoughts, rated their anxiety as more visible, appraised their performance more negatively, and engaged in more negative and less positive PEP than participants that held the control self-image. Collectively the results indicate that negative imagery is causally involved in the maintenance of social phobia, as well as in the generation of social anxiety among non-anxious individuals.     

A neutral face is not neutral even if you have not seen it: social anxiety disorder and affective priming with facial expressions

Cognitive theories suggest that social anxiety disorder (SAD) is characterized by biased processing of negative facial expressions. Recently, however, it has been proposed that the fear of positive evaluation may play an additional, important role. In order to investigate which specific expressions evoke biased processing, 15 patients diagnosed with SAD and 15 non-anxious controls (NACs) completed an affective priming procedure: they rated neutral symbols which were preceded by sub-optimally presented primes of angry, neutral, and smiling faces. Patients with SAD rated the symbols significantly more negatively than NACs when they were primed with a neutral face. In addition, SAD patients tended to rate all symbols significantly more negatively suggesting that all faces (negative, positive, and neutral) are threatening to SAD patients.     

Attention to Positive and Negative Social-Evaluative Words: Investigating the Effects of Social Anxiety,Trait Anxiety and Social Threat

The study investigated how attention to negative (threatening) and positive social-evaluative words is affected by social anxiety, trait anxiety and the expectation of social threat. High and low socially anxious individuals carried out a modified dot-probe task either while expecting to give a speech or under non-threatening conditions. High socially anxious individuals showed no significant attentional bias towards or away from social-evaluative words. This result significantly contrasted with an identical design that showed avoidance of emotional faces in high socially anxious participants drawn from the same population (Mansell et al ., 1999). Participants who expected to give a speech showed less attentional avoidance of negative and positive social-evaluative words. High trait anxiety was associated with selective attention to negative relative to positive social-evaluative words, consistent with earlier findings of attention to threat cues in high trait-anxious individuals. Implications for designing attention tasks and attentional bias across different dimensions of anxiety are discussed.
