A Comparison of Attentional Biases and Memory Biases in Women With Social Phobia and Major Depression.

Cognitive processes play an important role in the etiology and maintenance of anxiety and depression. Current theories differ, however, in their predictions regarding the occurrence of attentional biases and memory biases in depression and anxiety. To allow for a systematic comparison of disorders and cognitive processes, 117 women (35 with generalized social phobia, 27 with major depression, and 55 healthy controls) participated in a test of visual attention (visual search), an explicit memory test (free recall), and an implicit memory test (anagram solving). Both clinical groups exhibited attentional biases for disorder-related words, whereas only depressed participants showed clear evidence of explicit and implicit memory biases. The implications of these results for competing theories are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Selective Attention to Angry Faces in Clinical Social Phobia.

This study investigated the time course of attentional responses to emotional facial expressions in a clinical sample with social phobia. With a visual probe task, photographs of angry, happy, and neutral faces were presented at 2 exposure durations: 500 and 1,250 ms. At 500 ms, the social phobia group showed enhanced vigilance for angry faces, relative to happy and neutral faces, in comparison with normal controls. In the 1,250-ms condition, there were no significant attentional biases in the social phobia group. Results are consistent with a bias in initial orienting to threat cues in social anxiety. Findings are discussed in relation to recent cognitive models of anxiety disorders. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Effects of emotion concepts on perceptual memory for emotional expressions.

Three experiments tested the hypothesis that explaining emotional expressions using specific emotion concepts at encoding biases perceptual memory for those expressions. In Experiment 1, participants viewed faces expressing blends of happiness and anger and created explanations of why the target people were expressing one of the two emotions, according to concepts provided by the experimenter. Later, participants attempted to identify the facial expressions in computer movies, in which the previously seen faces changed continuously from anger to happiness. Faces conceptualized in terms of anger were remembered as angrier than the same faces conceptualized in terms of happiness, regardless of whether the explanations were told aloud or imagined. Experiments 2 and 3 showed that explanation is necessary for the conceptual biases to emerge fully and extended the finding to anger-sad expressions, an emotion blend more common in real life.

Recognition Accuracy and Response Bias to Happy and Sad Facial Expressions in Patients With Major Depression.

Impaired facial expression recognition has been associated with features of major depression, which could underlie some of the difficulties in social interactions in these patients. Patients with major depressive disorder and age- and gender-matched healthy volunteers judged the emotion of 100 facial stimuli displaying different intensities of sadness and happiness and neutral expressions presented for short (100 ms) and long (2,000 ms) durations. Compared with healthy volunteers, depressed patients demonstrated subtle impairments in discrimination accuracy and a predominant bias away from the identification as happy of mildly happy expressions. The authors suggest that, in depressed patients, the inability to accurately identify subtle changes in facial expression displayed by others in social situations may underlie the impaired interpersonal functioning.

The confounded nature of angry men and happy women.

Findings of 7 studies suggested that decisions about the sex of a face and the emotional expressions of anger or happiness are not independent: Participants were faster and more accurate at detecting angry expressions on male faces and at detecting happy expressions on female faces. These findings were robust across different stimulus sets and judgment tasks and indicated bottom-up perceptual processes rather than just top-down conceptually driven ones. Results from additional studies in which neutrally expressive faces were used suggested that the connections between masculine features and angry expressions and between feminine features and happy expressions might be a property of the sexual dimorphism of the face itself and not merely a result of gender stereotypes biasing the perception.

Attentional bias for threat in older adults: Moderation of the positivity bias by trait anxiety and stimulus modality.

Socioemotional selectivity theory suggests that emotion regulation goals motivate older adults to preferentially allocate attention to positive stimuli and away from negative stimuli. This study examined whether anxiety moderates the effect of the positivity bias on attention for threat. The authors employed the dot probe task to compare subliminal and supraliminal attention for threat in 103 young and 44 older adults. Regardless of anxiety, older but not young adults demonstrated a vigilant–avoidant response to angry faces. Anxiety influenced older adults’ attention such that anxious individuals demonstrated a vigilant–avoidant reaction to sad faces but an avoidant–vigilant reaction to negative words.

The face in the crowd effect unconfounded: Happy faces, not angry faces, are more efficiently detected in single- and multiple-target visual search tasks.

Is it easier to detect angry or happy facial expressions in crowds of faces? The present studies used several variations of the visual search task to assess whether people selectively attend to expressive faces. Contrary to widely cited studies (e.g., ?hman, Lundqvist, & Esteves, 2001) that suggest angry faces “pop out” of crowds, our review of the literature found inconsistent evidence for the effect and suggested that low-level visual confounds could not be ruled out as the driving force behind the anger superiority effect. We then conducted 7 experiments, carefully designed to eliminate many of the confounding variables present in past demonstrations. These experiments showed no evidence that angry faces popped out of crowds or even that they were efficiently detected. These experiments instead revealed a search asymmetry favoring happy faces. Moreover, in contrast to most previous studies, the happiness superiority effect was shown to be robust even when obvious perceptual confounds—like the contrast of white exposed teeth that are typically displayed in smiling faces—were eliminated in the happy targets. Rather than attribute this effect to the existence of innate happiness detectors, we speculate that the human expression of happiness has evolved to be more visually discriminable because its communicative intent is less ambiguous than other facial expressions.

Do happy faces capture attention? The happiness superiority effect in attentional blink.

This study investigated the influence of positive affect on attentional blink (AB) with schematic faces. Results of Experiment 1 showed that the AB effect was smaller for both upright and inverted positive face icons than other face icons (neutral and angry faces) of corresponding orientations, confirming and extending the results of the earlier study by Mack, Pappas, Silverman, and Gay (2002). Results of Experiment 2 demonstrated that this attenuation of AB was unlikely to be attributable to attentional capture by the happy face. Perceptual saliency is suggested as a likely cause of the effect. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Attentional and perceptual factors affecting the attentional blink for faces and objects.

When 2 different visual targets presented among different distracters in a rapid serial visual presentation (RSVP) are separated by 400 ms or less, detection and identification of the 2nd targets are reduced relative to longer time intervals. This phenomenon, termed the attentional blink (AB), is attributed to the temporary engagement of a limited-capacity attentional system by the 1st target, which reduces resources available for processing the 2nd target. Although AB has been reliably obtained with many stimulus types, it has not been found for faces (E. Awh et al., 2004). In the present study, the authors investigate the underpinnings of this immunity. Unveiling circumstances in which AB occurs within and across faces and other categories, the authors demonstrate that a multichannel model cannot account for the absence of AB effects on faces. The authors suggest instead that perceptual salience of the face within the distracters' series as well as the available resources determine whether or not faces are blinked in RSVP.

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.

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.

Frontolimbic Response to Negative Feedback in Clinical Depression.

Functional neuroimaging suggests that limbic regions of the medial frontal cortex may be abnormally active in individuals with depression. These regions, including the anterior cingulate cortex, are engaged in both action regulation, such as monitoring errors and conflict, and affect regulation, such as responding to pain. The authors examined whether clinically depressed subjects would show abnormal sensitivity of frontolimbic networks as they evaluated negative feedback. Depressed subjects and matched control subjects performed a video game in the laboratory as a 256-channel EEG was recorded. Speed of performance on each trial was graded with a feedback signal of A, C, or F. By 350 ms after the feedback signal, depressed subjects showed a larger medial frontal negativity for all feedback compared with control subjects with a particularly striking response to the F grade. This response was strongest for moderately depressed subjects and was attenuated for subjects who were more severely depressed. Localization analyses suggested that negative feedback engaged sources in the anterior cingulate and insular cortices. These results suggest that moderate depression may sensitize limbic networks to respond strongly to aversive events. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Orienting and maintenance of gaze to facial expressions in social anxiety.

In 2 experiments, the authors tested predictions from cognitive models of social anxiety regarding attentional biases for social and nonsocial cues by monitoring eye movements to pictures of faces and objects in high social anxiety (HSA) and low social anxiety (LSA) individuals. Under no-stress conditions (Experiment 1), HSA individuals initially directed their gaze toward neutral faces, relative to objects, more often than did LSA participants. However, under social-evaluative stress (Experiment 2), HSA individuals showed reduced biases in initial orienting and maintenance of gaze on faces (cf. objects) compared with the LSA group. HSA individuals were also relatively quicker to look at emotional faces than neutral faces but looked at emotional faces for less time, compared with LSA individuals, consistent with a vigilant-avoidant pattern of bias.

Interpersonal pathoplasticity in individuals with generalized anxiety disorder.

Recent theories of generalized anxiety disorder (GAD) have emphasized interpersonal and personality functioning as important aspects of the disorder. We examined heterogeneity in interpersonal problems in 2 studies of individuals with GAD (n = 47 and n = 83). Interpersonal subtypes were assessed with the Inventory of Interpersonal Problems–Circumplex (Alden, Wiggins, & Pincus, 1990). Across both studies, individuals with GAD exhibited heterogeneous interpersonal problems, and cluster analyses of these patients' interpersonal characteristics yielded 4 replicable clusters, identified as intrusive, exploitable, cold, and nonassertive subtypes. Consistent with our pathoplasticity hypotheses, clusters did not differ with GAD severity, anxiety severity, or depression severity. Clusters in Study 2 differed on rates of personality disorders, including avoidant personality disorder, further providing support for the validity of interpersonal subtypes. The presence of interpersonal subtypes in GAD may have important implications for treatment planning and efficacy. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Panic and Comorbid Anxiety Symptoms in a National Anxiety Screening Sample: Implications for Clinical Interventions.

Questionnaire data from 2,033 participants in the National Anxiety Disorders Screening Day sample were used to assess the presence of panic and comorbid anxiety problems. These participants were selected from more than 15,000 attendees on the basis of never having received treatment for a psychiatric disorder and meeting screening criteria for panic disorder. With each comorbid anxiety problem (generalized anxiety disorder, posttraumatic stress disorder, social phobia, and obsessive-compulsive disorder), participants had a corresponding increase in interference in daily living as well as readiness to seek treatment. The addition of generalized anxiety or depression with panic symptoms resulted in marked increases in interference scores. Clinical treatment implications for panic disorder are discussed in terms of the effects of comorbid anxiety problems. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Mood-Congruent Attentional Bias in Dysphoria: Maintained Attention to and Impaired Disengagement From Negative Information.

Attentional bias to negative information has been proposed to be a cognitive vulnerability factor for the development of depression. In 2 experiments, the authors examined mood-congruent attentional bias in dysphoria. In both experiments, dysphoric and nondysphoric participants performed an attentional task with negative, positive, and neutral word cues preceding a target. Targets appeared either at the same or at the opposite location of the cue. Overall, results indicate that dysphoric participants show maintained attention for negative words at longer stimulus presentations, which is probably caused by impaired attentional disengagement from negative words. Furthermore, nondysphoric participants maintain their attention more strongly to positive words. These results are discussed in relation to recent developments in the pathogenesis and treatment of depression. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Selective attention to facial emotion in physically abused children.

The ability to allocate attention to emotional cues in the enviromnent is an important feature of adaptive self-regulation. Existing data suggest that physically abused children overattend to angry expressions, but the attentional mechanisms underlying such behavior are unknown. The authors tested 8-11-year-old physically abused children to determine whether they displayed specific information-processing problems in a selective attention paradigm using emotional faces as cues. Physically abused children demonstrated delayed disengagement when angry faces served as invalid cues. Abused children also demonstrated increased attentional benefits on valid angry trials. Results are discussed in terms of the influence of early adverse experience on children's selective attention to threat-related signals as a mechanism in the development of psychopathology.

A multidimensional meta-analysis of treatments for depression, panic, and generalized anxiety disorder: An empirical examination of the status of empirically supported therapies.

The authors report a meta-analysis of high-quality studies published from 1990-1998 on the efficacy of manualized psychotherapies for depression, panic disorder, and generalized anxiety disorder (GAD) that bear on the clinical utility and external validity of empirically supported therapies. The results suggest that a substantial proportion of patients with panic improve and remain improved; that treatments for depression and GAD produce impressive short-term effects; that most patients in treatment for depression and GAD do not improve and remain improved at clinically meaningful follow-up intervals; and that screening procedures used in many studies raise questions about generalizability, particularly in light of a systematic relation across studies between exclusion rates and outcome. The data suggest the importance of reporting, in both clinical trials and meta-analyses, a range of outcome indices that provide a more comprehensive, multidimensional portrait of treatment effects and their generalizability. These include exclusion rates, percent improved, percent recovered, percent who remained improved or recovered at follow-up, percent seeking additional treatment at follow-up, and data on both completer and intent-to-treat samples.

Clinical risk factors for the generation of life events in major depression.

This study examines the relationship of anxiety disorder and dysthymia comorbidity to the generation of life events prior to major depression episode onset in a cross-sectional community sample of 76 women. Those with comorbid anxiety and dysthymia experienced higher rates of events that were at least partly dependent on their own behavior but did not differ from those without these clinical risk factors on independent life events outside of their control. This relationship remained significant even after controlling for overall severity of depression and demographic covariates. The implications of these results for understanding the increased rates of major depression onset and recurrence among those with comorbid anxiety and dysthymia are discussed as avenues of future research.
