The contextual goal dependent attentional flexibility (CoGoDAF) framework: A new approach to attention bias in depression. Behav Res Ther 2023; 167:104354. [PMID: 37343329 DOI: 10.1016/j.brat.2023.104354] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/21/2022] [Revised: 05/30/2023] [Accepted: 06/09/2023] [Indexed: 06/23/2023]
Abstract
Successful adaptation to the environment requires attentional prioritization of emotional information relevant to the current situational demands. Accordingly, the presence of an attention bias (AB) for both positive and negative information may allow preferential processing of stimuli in line with the current situational goals. However, AB for negative information sometimes becomes maladaptive, being antithetical to the current adaptive needs and goals of an individual, such as in the case of affective disorders such as depression. Although difficulties in flexible shifting between emotional stimuli in depression have increasingly become a topic of discussion in the field, an integrative approach towards biased versus flexible emotional attentional processes remains absent. In the present paper, we advance a novel and integrative view of conceptualizing potentially aberrant affective attention patterns in depression as a function of the current contextual features. We propose that flexible emotional attention takes place as a result of attention prioritization towards goal-relevant emotional stimuli depending upon the current context of the individual. Specifically, the roles of context, distal and proximal goals, and approach and avoidance motivation processes are considered in a unified manner. The empirical, clinical, and interventional implications of this integrative framework provide a roadmap for future psychological and neurobiological experimental and translational research.

Vigilance-Avoidance Toward Negative Faces in Social Anxiety With and Without Comorbid Depression. Front Psychiatry 2021; 12:636961. [PMID: 33868053 PMCID: PMC8044761 DOI: 10.3389/fpsyt.2021.636961] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/04/2020] [Accepted: 03/09/2021] [Indexed: 11/13/2022] Open
Abstract
Despite the growing evidence for the attentional bias toward emotional related stimuli in patients with social anxiety disorder (SAD), it remains unclear how the attentional bias manifests in normal individuals with SAD and/or depressive traits. To address this question, we recruited three groups of normal participants with different psychiatric traits-individuals with comorbid SAD and depression (SADd, N = 19), individuals with only SAD (SAD, N = 15), and healthy control individuals (HC, N = 19). In a dot-probe paradigm, participants view angry, disgusted, and sad face stimuli with durations ranging from very brief (i.e., 14ms) that renders stimuli completely intangible, to relatively long (i.e., 2000ms) that guarantees image visibility. We find significant early vigilance (i.e., on brief stimuli) and later avoidance (i.e., on long stimuli) toward angry faces in the SADd group. We also find vigilance toward angry and disgusted faces in the SAD group. To our best knowledge, this is the first study to unify both vigilance and avoidance within the same experimental paradigm, providing direct evidence for the "vigilance-avoidance" theory of comorbid SAD and depression. In sum, these results provide evidence for the potential behavioral differences induced by anxiety-depression comorbidity and a single trait in non-clinical populations, but the lack of a depression-only group cannot reveal the effects of high levels of depression on the results. The limitations are discussed.

Attentional Bias in specific symmetry and cleaning dimensions of obsessive-compulsive disorder. J Anxiety Disord 2020; 73:102238.

Abstract
Attentional bias (AB) refers to increased allocation of attention on threat stimuli when compared to neutral stimuli. It is not clear if AB occurs in subjects with obsessive-compulsive disorder (OCD). We tested AB for symmetry and cleaning symptoms of OCD. Sixty-two patients with OCD and 40 healthy controls matched by gender, age and IQ, completed a computerized dot-probe task where two pictures (with symmetry or cleaning related content) were shown. The probe appeared in the location previously occupied by one of the pictures. Within-subjects linear mixed-effect models were used to investigate the effects of the factors: group (patients vs controls), OCD dimension (cleaning vs symmetry), task condition (neutral, congruent and incongruent), and the interaction among them. We also correlated AB scores with the clinical and demographic variables. No positive interaction resulted among the factors, but positive results were observed in group and condition, separately. Patients were significantly slower than controls (p-value = 0.014) (an effect that was accounted for by depression and anxiety symptoms and comorbidity) and the neutral condition was significantly faster when compared the other two conditions (congruent and incongruent, p-value = 0.013). No association was found between AB scores and clinical symptoms. There was no AB toward specific, content-related, stimuli in this sample of OCD patients.

Attention allocation to subliminally presented affective faces in high and low social anxiety. Int J Psychophysiol 2020; 153:159-165. [PMID: 32389619 DOI: 10.1016/j.ijpsycho.2020.04.017] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2019] [Revised: 04/04/2020] [Accepted: 04/22/2020] [Indexed: 11/17/2022]
Abstract
Attention bias to affective stimuli, particularly threatening stimuli, has been well documented, with attention bias to affective faces often reported in populations with social anxiety (SA). However, inconsistencies exist in the literature regarding the direction of the bias, with some studies reporting a bias to attend toward social threat, and others reporting a bias to avoid social threat. This variability in the attention bias literature could be related to fluctuations in how attentional resources are allocated toward social stimuli over time. This study aimed to isolate early processing of affective faces using a backward masking paradigm in participants with high and low levels of subclinical SA. We used prepulse inhibition (PPI) of startle to index the amount of early attention allocated to masked affective faces. There was greater PPI to masked angry faces compared to neutral faces across all participants, suggesting that more attention was allocated to threatening faces. This effect was similar across face genders and participant SA levels. There was also a trend for more attention to be allocated to masked affective faces (angry and happy) compared to neutral faces across all participants. These findings demonstrate that attention bias to subliminal affect, and threat specifically, may not be modulated by subclinical levels of SA at very early stages of attention processing.

Avoidance of all feedback? Attention allocation during and after public speech in social anxiety. J Behav Ther Exp Psychiatry 2020; 66:101520. [PMID: 31675486 DOI: 10.1016/j.jbtep.2019.101520] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/30/2018] [Revised: 09/17/2019] [Accepted: 10/07/2019] [Indexed: 10/25/2022]
Abstract
BACKGROUND AND OBJECTIVES Attention avoidance of feedback-related stimuli is proposed to be associated with and maintain social anxiety. However, previous research has mainly focused on comparing the attention bias between two types of stimuli, while little is known about attention distribution patterns among positive, neutral, and negative feedback and non-feedback stimuli in individuals with high trait social anxiety (HSA) or low trait social anxiety (LSA). METHODS The current study assessed eye movement pattern of participants with HSA or LSA during a speech task (high anxiety condition) or while solely watching audience feedback of the speech (low anxiety condition). A pre-recorded audience who displayed approving, neutral, or disapproving gestures was presented as feedback stimuli, while neutral facial photos were used as non-feedback stimuli. RESULTS Only in the high anxiety condition, participants with HSA exhibited longer total fixation on non-feedback stimuli compared to those with LSA; whereas in the low anxiety condition, both groups paid more attention to emotional feedback stimuli. LIMITATIONS The final sample size was modest due to a high suspicion rate of the reality of the audience. CONCLUSIONS These findings suggest that only in highly anxious social situations, socially anxious individuals lack the attentional preference toward positive feedback that individuals with low anxious have.

Insula activation is modulated by attention shifting in social anxiety disorder. J Anxiety Disord 2018; 56:56-62.

Abstract
Social anxiety disorder (SAD) is characterized by exaggerated reactivity to social threat, often documented by biased attention to threatening information, and increased activation in brain regions involved in salience/threat processing. Attention training has been developed to ameliorate the attention bias documented in individuals with SAD, with mixed results. We investigated patterns of brain activation underlying acute attention modulation in 41 participants (29 with SAD and 12 health controls). We then investigated how brain activation changed over time in both groups in response to a 4-session attention training protocol (toward threat, away from threat, no-training control). Results revealed diminished pre-training deactivation in the insula in SAD participants during attention modulation. SAD participants also demonstrated an increase in insula deactivation over time, suggestive of an improvement in attention modulation of emotion, and this was associated with a decrease in symptom severity. Attention training did not, itself, lead to clinical improvement, though there was a trend level effect of training toward threat on increased insula deactivation over time. While deficits in attentional control and emotion modulation are documented in individuals with SAD, current attention training protocols are not robustly effective in ameliorating aberrant functioning. Pursuit of training protocols that have more robust impacts on the relevant neural circuitry may have some value.

Anxiety, fatigue, and attentional bias toward threat in patients with hematopoietic tumors. PLoS One 2018; 13:e0192056.

Abstract
Cancer patients with hematopoietic tumors exhibit particularly high rates of anxiety disorders and depression, and often develop negative affect. In addition, psychological problems experienced by cancer patients impair their quality of life. When cancer patients feel anxious, they tend to direct their attention toward stimuli associated with threat in the surrounding environment. If attentional bias occurs in patients with hematopoietic tumors, who are at particular risk of developing negative affect, resolution of the bias could be useful in alleviating their anxiety. The current study examined the association between attentional bias and negative affect in patients with hematopoietic tumors and tested the hypothesis that negative affect would be more severe in those who exhibited greater attentional bias. Twenty-seven patients with hematopoietic tumors participated in the study. Reaction time (RT) was measured as the time between the presentation of the threatening and neutral images, and the subject’s button press to indicate choice (neutral expressions). Eight combinations of “threatening” expressions with high emotional valence and “neutral” expressions with low emotional valence were presented. The images used to measure attentional bias were taken from the Japanese Female Facial Expression Database and had been rated as expressive of anger, sadness, or neutrality, with predetermined emotional valence. Psychological testing was performed with the Profile of Mood States (POMS). To examine the association between attentional bias and negative affect, we calculated Spearman's rank correlation coefficients for RTs and POMS. Subjects’ mean RT was 882.9 (SD = 100.9) ms, and 19 of the 27 subjects exhibited slower RTs relative to healthy individuals. RT was significantly positively correlated with Tension-Anxiety (r = .679, p < .01) and Fatigue (r = .585, p < .01) subscale scores. The results of the study suggested that attentional bias toward threatening expressions could be positively correlated with the mental intensity of anxiety and fatigue in patients with hematopoietic tumors.

Abstract
PURPOSE Persons who stutter (PWS) and those with social anxiety disorder may exhibit fear of negative evaluation (FNE) and anxiety in social situations. However, the information processing biases that perpetuate these characteristics have had limited investigation. This study investigated judgment bias in social situations. METHOD Participants included 50 adults who stutter and 45 age- and gender-matched fluent persons who do not stutter (PWNS), who made up the control group. Participants completed the Interpretation and Judgmental Questionnaire (Voncken, Bögels, & deVries, 2003), and threat scores were calculated. RESULTS There were no significant differences between PWS and PWNS in social threat or nonsocial threat scores. When the PWS group was divided on the basis of FNE and compared with PWNS participants without heightened anxiety (n = 35), the PWS with high FNE had significantly higher total social threat scores than the PWS with low FNE. The three groups did not differ in threat ratings for ambiguous or profoundly negative social situations. CONCLUSIONS Judgment bias in PWS is mediated by the magnitude of FNE present; not all PWS exhibit judgment bias for social situations. Treatment implications include the need for psychosocial support addressing the negative impacts on quality of life and restrictions on social engagement that stuttering may cause in some individuals.

Abstract
OBJECTIVE The effects of coexisting psychopathology on disorder-specific attentional biases in patients with alcohol dependence are uncertain. We undertook a cross-sectional study assessing attentional biases to alcohol-, depression-, and anxiety- related stimuli using the visual probe task in patients with alcohol dependence, attending a community alcohol service. METHODS Using the visual probe task, we presented disorder-specific words (relating to alcohol, anxiety, and depression) for 500 ms and measured reaction times. RESULTS Participants demonstrated a significant attentional bias towards alcohol-related cues (mean 8.5, p = 0.03) but significant avoidance of depression-related cues (mean -8.4, p = 0.01). The subgroup of participants who were recently abstinent (n = 70) showed greatest avoidance of depression-related cues (t(69) = 2.68, p < 0.01) but no significant vigilance towards alcohol or anxiety cues, whereas those still drinking (n = 43) showed attentional biases towards alcohol-related (t(42) = 2.70, p = 0.01) and social anxiety-related cues (t(42) = 2.84, p < 0.01). In the whole sample, the magnitude of attentional bias to alcohol was not correlated with length of drinking history, number of comorbid conditions, or severity of anxiety/depression. CONCLUSIONS In a clinical sample of alcohol-dependent patients, further investigation is required to explore whether these attentional biases reflect current drinking status or factors indicating prognosis.

Abstract
Children with autism spectrum disorder (ASD) have high levels of anxiety. It is unclear whether they exhibit threat-related attentional biases commensurate with anxiety disorders as manifest in non-ASD populations, such as facilitated attention toward, and difficulties disengaging engaging from, threatening stimuli. Ninety children, 45 cognitively able with ASD and 45 age, perceptual-IQ, and gender matched typically developing children, aged 7-12 years, were administered a visual dot probe task using threatening facial pictures. Parent-reported anxiety symptoms were also collected. Children with ASD showed similarly high levels of anxiety compared with normative data from an anxiety disordered sample. Children with ASD had higher levels of parent-reported anxiety but did not show differences in disengaging from, or facilitated attention toward, threatening facial stimuli compared with typically developing children. In contrast to previously published studies of anxious children, in this study there were no differences in attentional biases in children with ASD meeting clinical cutoff for anxiety and those who did not. There were no correlations between attentional biases and anxiety symptoms and no gender differences. These findings indicate the cognitive mechanisms underlying anxiety in cognitively able children with ASD could differ from those commonly found in anxious children which may have implications for both understanding the aetiology of anxiety in ASD and for anxiety interventions.

Abstract
BACKGROUND AND OBJECTIVES Difficulties with attentional control have long been thought to play a key role in anxiety and depressive disorders. However, the nature and extent of attentional control difficulties in social anxiety disorder (SAD) are not yet well understood. The current study was designed to assess whether attentional control for non-emotional information is impaired in SAD when taking comorbid depression into account.. METHODS Individuals with SAD and healthy controls (HCs) were administered an attentional blink (AB) task in which they identified number targets in a rapid serial visual presentation stream of letters. RESULTS Individuals with SAD and current comorbid depression exhibited reduced accuracy to identify a target that fell within the AB window after the presentation of a first target compared to individuals with SAD without current comorbid depression, as well as to HCs. The latter two groups did not differ from each other, and the three groups did not differ in accuracy for the second target when it was presented after the AB window. LIMITATIONS Although we included two clinical groups and the sample size for the non-comorbid SAD group was large, the comorbid SAD group was relatively small. CONCLUSIONS These results suggest that impaired attentional control among individuals with SAD may be limited to those suffering from current comorbid depression..

Abstract
Cognitive models assume that social anxiety is associated with and maintained by biased information processing, leading to change in attention allocation, which can be measured by examining eye movement. However, little is known about the distribution of attention among positive, neutral and negative stimuli during a social task and the relative importance of positive versus negative biases in social anxiety. In this study, eye movement, subjective state anxiety and psychophysiology of individuals with high trait social anxiety (HSA) and low trait social anxiety (LSA) were measured during a speech task with a pre-recorded audience. The HSA group showed longer total fixation on negative stimuli and shorter total fixation on positive stimuli compared to the LSA group. We observed that the LSA group shifted attention away from negative stimuli, whereas the HSA group showed no differential attention allocation. The total duration of fixation on negative stimuli predicted subjective anxiety ratings. These results point to a negative bias as well as a lack of a positive bias in HSA individuals during social threat.

Abstract
Several decades of research converge on the formulation that individuals diagnosed with major depressive disorder (MDD) exhibit negative biases in their processing of emotional information. It is becoming increasingly clear, however, that traditional between-group comparisons have obscured the substantial heterogeneity of cognitive and affective dysfunction that is associated with depressive symptomatology. In this article, we review the findings of research examining attention to and memory for negative emotional information using a more dimensional perspective on depression. Specifically, we explore studies that assess cognitive biases along a continuum of depressive symptom severity and consider the influence of co-occurring dimensions of functioning, in particular the severity of anxiety symptoms. Finally, we identify critical empirical questions and issues in this growing literature.

Abstract
Social anxiety disorder (SAD) is a debilitating mental illness which is thought to be maintained in part by the aberrant attentional processing of socially relevant information. Critically however, research has not assessed whether such aberrant attentional processing occurs during social-evaluative contexts characteristically feared in SAD. The current study presents a novel approach for the assessment of the visuocognitive biases operating in SAD during a social-evaluative stressor. For this task, clinically socially anxious participants and controls were required to give a brief impromptu speech in front of a pre-recorded audience who intermittently displayed socially positive or threatening gestures. Participant gaze at the audience display was recorded throughout the speech. Socially anxious participants exhibited a significantly longer visual scanpath, relative to controls. In addition, socially anxious participants spent relatively longer time fixating at the non-social regions in between and around the confederates. The findings of the present study suggest that SAD is associated with hyperscanning and the attentional avoidance of social stimuli.

Abstract
Implicit associations of the self to concepts like "calm" have been shown to be weaker in persons with social anxiety than in non-anxious healthy controls. However, other implicit self associations, such as those to acceptance or rejection, have been less studied in social anxiety, and none of this work has been conducted with clinical samples. Furthermore, the importance of depression in these relationships has not been well investigated. We addressed these issues by administering two Implicit Association Tests (IATs; Greenwald, McGhee, & Schwartz, 1998), one examining the implicit association of self/other to anxiety/calmness and the other examining the association of self/other to rejection/acceptance, to individuals with generalized social anxiety disorder (SAD, n=85), individuals with generalized SAD and a current or past diagnosis of major depressive disorder or current dysthymic disorder (n=47), and non-anxious, non-depressed healthy controls (n=44). The SAD and SAD-depression groups showed weaker implicit self-calmness associations than healthy controls, with the comorbid group showing the weakest self-calmness associations. The SAD-depression group showed the weakest implicit self-acceptance associations; no difference was found between non-depressed individuals with SAD and healthy controls. Post hoc analyses revealed that differences appeared to be driven by those with current depression. The SAD-only and SAD-depression groups did not differ in self-reported (explicit) social anxiety. The implications of these findings for the understanding of SAD-depression comorbidity and for the treatment of SAD are considered.

OBJECTIVES Anxiety leads to biases in processing personally relevant information. This study set out to examine whether anxious parents also experience biases in processing child-relevant material. DESIGN AND METHODS Ninety parents acted as a control condition, or received a social anxiety or child-related anxiety induction. They completed a task examining attentional biases in relation to child-threat words and social-threat words, and a task examining ability to categorize emotion in children's faces and voices. RESULTS There was a trend indicating group differences in attentional bias towards social-threat words, and this appears to have been only in the social anxiety condition, but not the child anxiety or control conditions. For child-threat words, attentional bias was present in the child anxiety condition, but not the social anxiety or control conditions. In the emotion recognition task, there was no difference between the control and child anxiety conditions, but the social anxiety condition were more likely to erroneously label children's faces and voices as sad. CONCLUSIONS Parents' anxious biases may spill over into their child's world. PRACTITIONER POINTS Parents' anxious biases may spill over into their child's world. Anxious parents may have attentional biases towards threats in their children's environment. Anxious parents may over-attribute negative emotion to children.

Attentional bias and attentional control in Posttraumatic Stress Disorder. J Anxiety Disord 2014; 28:203-10.

Abstract
Extensive evidence exists for an association between attentional bias (AB; attentional vigilance or avoidance) and anxiety. Recent studies in healthy participants suggest that attentional control (AC) may facilitate inhibition of automatic attentional processes associated with anxiety. To investigate relationships among AC, trauma-related AB, symptom severity and trait anxiety in patients with Posttraumatic Stress Disorder (PTSD), participants (N = 91) completed self-report measures of AC, posttraumatic stress symptoms (PTSS) and trait anxiety. AB was measured with a pictorial version of the Dot Probe Test. AC moderated the relationship between PTSS and AB (threat avoidance). Patients high in PTSS and low in AC showed attentional avoidance. No association between PTSS and AB in patients with medium or high levels of AC was found. A similar pattern of results was observed for the relationship between trait anxiety, AC and AB. These results suggest that a low ability to control attention is a risk factor for AB in PTSD. This first clinical study corroborates the accumulating evidence from analog studies that individual differences in top-down attentional control are of considerable importance in the expression of AB in anxious psychopathology.

Abstract
Whether Obsessive Compulsive Disorder (OCD) is associated with an increased attentional bias to emotive stimuli remains controversial. Additionally, it is unclear whether comorbid depression modulates abnormal emotional processing in OCD. This study examined attentional bias to OC-relevant scenes using a visual search task. Controls, non-depressed and depressed OCD patients searched for their personally selected positive images amongst their negative distractors, and vice versa. Whilst the OCD groups were slower than healthy individuals in rating the images, there were no group differences in the magnitude of negative bias to concern-related scenes. A second experiment employing a common set of images replicated the results on an additional sample of OCD patients. Although there was a larger bias to negative OC-related images without pre-exposure overall, no group differences in attentional bias were observed. However, OCD patients subsequently rated the images more slowly and more negatively, again suggesting post-attentional processing abnormalities. The results argue against a robust attentional bias in OCD patients, regardless of their depression status and speak to generalized difficulties disengaging from negative valence stimuli. Rather, post-attentional processing abnormalities may account for differences in emotional processing in OCD.

Internet-based attention bias modification for social anxiety: a randomised controlled comparison of training towards negative and training towards positive cues. PLoS One 2013; 8:e71760.

Abstract
Biases in attention processes are thought to play a crucial role in the aetiology and maintenance of Social Anxiety Disorder (SAD). The goal of the present study was to examine the efficacy of a programme intended to train attention towards positive cues and a programme intended to train attention towards negative cues. In a randomised, controlled, double-blind design, the impact of these two training conditions on both selective attention and social anxiety were compared to that of a control training condition. A modified dot probe task was used, and delivered via the internet. A total of 129 individuals, diagnosed with SAD, were randomly assigned to one of these three conditions and took part in a 14-day programme with daily training/control sessions. Participants in all three groups did not on average display an attentional bias prior to the training. Critically, results on change in attention bias implied that significantly differential change in selective attention to threat was not detected in the three conditions. However, symptoms of social anxiety reduced significantly from pre- to follow-up-assessment in all three conditions (dwithin = 0.63–1.24), with the procedure intended to train attention towards threat cues producing, relative to the control condition, a significantly greater reduction of social fears. There were no significant differences in social anxiety outcome between the training condition intended to induce attentional bias towards positive cues and the control condition. To our knowledge, this is the first RCT where a condition intended to induce attention bias to negative cues yielded greater emotional benefits than a control condition. Intriguingly, changes in symptoms are unlikely to be by the mechanism of change in attention processes since there was no change detected in bias per se. Implications of this finding for future research on attention bias modification in social anxiety are discussed. Trial Registration ClinicalTrials.gov NCT01463137

Abstract
In cognitive theory it is hypothesized that panic attacks are provoked by catastrophic misinterpretations of bodily sensations. The aim of the present study was to investigate the ability of associated word pairs referring to catastrophic thinking (e.g. palpitations-heart attack) in producing panic attacks. Patients with PD (n = 20), patients with mixed anxiety disorders (n = 20), and a healthy control group (n = 30) participated in the present study. To enhance ecological validity we first conducted a stimulus validation experiment. Subsequently, nine suitable panic and neutral word pairs were presented in block to the participants. Anxiety levels were assessed before and after the presentation. PD patients were more anxious when reading these word pairs, compared to neutral word pairs. However, none of the participants experienced a panic attack upon reading the word pairs. From the present results it seems that catastrophic thinking is rather related to the anticipatory anxiety for panic attacks, but not necessarily with the occurrence of the panic attacks themselves.

Abstract
Guided Internet-based cognitive-behavioural self-help (ICBT) has been proven to be effective for social anxiety disorder (SAD) by several independent research groups. However, as the proportion of clinical significant change has room for improvement, new treatments should be developed and investigated. A novel treatment is attention bias modification (ABM). This study aimed at evaluating the combination of ABM and ICBT. We compared two groups, one group receiving ICBT and ABM targeting attentional avoidance and the other group receiving ICBT and control training. ABM and control training tasks were both based on the dot-probe paradigm. A total of 133 participants, diagnosed with SAD, were randomised to these two groups. The attention training group (N = 66) received 2 weeks of daily attention training followed by 9 weeks of ICBT. The control group (N = 67) received 2 weeks of daily control training, also followed by 9 weeks of ICBT. Social anxiety measures as well as the attention bias were assessed at pre-assessment, at week 2, and at post-treatment. Results showed no significant differences between the attention training group and the control group. Both groups improved substantially on social anxiety symptoms from pre- to post-assessment (dwithin = 1.39-1.41), but showed no change in attention processes (dwithin = 0.10-0.17). In this trial, the attention modification training failed to induce differential change in attention bias. Results demonstrate that the applied ABM procedure with its focus on the reduction of attentional avoidance was ineffective in the Internet-based setting. The results do not suggest that adding ABM targeting attentional avoidance to ICBT results in better outcomes than ICBT alone.

Abstract
It has been proposed that social anxiety disorder (SAD) is associated with automatic information processing biases resulting in hypersensitivity to signals of social threat such as negative facial expressions. However, the nature and extent of automatic processes in SAD on the behavioral and neural level is not entirely clear yet. The present review summarizes neuroscientific findings on automatic processing of facial threat but also other disorder-related stimuli such as emotional prosody or negative words in SAD. We review initial evidence for automatic activation of the amygdala, insula, and sensory cortices as well as for automatic early electrophysiological components. However, findings vary depending on tasks, stimuli, and neuroscientific methods. Only few studies set out to examine automatic neural processes directly and systematic attempts are as yet lacking. We suggest that future studies should: (1) use different stimulus modalities, (2) examine different emotional expressions, (3) compare findings in SAD with other anxiety disorders, (4) use more sophisticated experimental designs to investigate features of automaticity systematically, and (5) combine different neuroscientific methods (such as functional neuroimaging and electrophysiology). Finally, the understanding of neural automatic processes could also provide hints for therapeutic approaches.

Abstract
Background Guided Internet-based cognitive-behavioral therapy (ICBT) has been found to be effective for social anxiety disorder (SAD) by several independent research groups. However, since the extent of clinically significant change demonstrated leaves room for improvement, new treatments should be developed and investigated. A novel treatment, which has generally been found to be effective, is cognitive bias modification (CBM). This study aims to evaluate the combination of CBM and ICBT. It is intended that two groups will be compared; one group randomized to receiving ICBT and CBM towards threat cues and one group receiving ICBT and control training. We hypothesize that the group receiving ICBT plus CBM will show superior treatment outcomes. Methods/design Participants with SAD (N = 128), will be recruited from the general population. A composite score combining the scores obtained from three social anxiety questionnaires will serve as the primary outcome measure. Secondary measures include self-reported depression and quality of life. All treatments and assessments will be conducted via the Internet and measurement points will be baseline, Week 2, post-treatment, and 4 months post-treatment. Discussion There is no direct evidence of the effects of combining CBM and ICBT in SAD. Adding attention-training sessions to ICBT protocols could increase the proportion of participants who improve and recover through Internet-based self-help.

Abstract
BACKGROUND Cognitive theorists relate anxiety disorders to the way in which emotional information is processed. The existing research suggests that patients with anxiety disorders tend to allocate their attention toward threat-related information selectively, and this may differ among different types of anxious subjects. The aim of this study was to explore attentional bias in patients with generalized anxiety disorder (GAD) and panic disorder (PD) using the emotional Stroop task and compare the differences between them. METHODS Forty-two patients with GAD, 34 patients with PD, and 46 healthy controls performed the emotional Stroop task with four word types, ie, GAD-related words, PD-related words, neutral words, and positive words. RESULTS Patients with GAD and those with PD were slower than healthy controls to respond to all stimuli. Patients with GAD had longer response latencies in color-naming both PD-relevant words and GAD relevant words. Patients with PD had longer response latencies only in color-naming PD-related words, similar to healthy controls. CONCLUSION Patients with GAD and those with PD had a different pattern of attentional bias, and there was insufficient evidence to support the existence of specific attentional bias in patients with PD.

Abstract
In this paper we examine the nature of automatic cognitive processing in anxiety disorders and Major Depressive Disorder (MDD). Rather than viewing automaticity as a unitary construct, we follow a social cognition perspective (Bargh, 1994) that argues for four theoretically independent features of automaticity: unconscious (processing of emotional stimuli occurs outside awareness), efficient (processing emotional meaning uses minimal attentional resources), unintentional (no goal is needed to engage in processing emotional meaning), and uncontrollable (limited ability to avoid, alter or terminate processing emotional stimuli). Our review of the literature suggests that most anxiety disorders are characterized by uncontrollable, and likely also unconscious and unintentional, biased processing of threat-relevant information. In contrast, MDD is most clearly typified by uncontrollable, but not unconscious or unintentional, processing of negative information. For the anxiety disorders and for MDD, there is no sufficient evidence to draw firm conclusions about efficiency of processing, though early indications are that neither anxiety disorders nor MDD are characterized by this feature. Clinical and theoretical implications of these findings are discussed and directions for future research are offered. In particular, it is clear that paradigms that more directly delineate the different features of automaticity are required to gain a more comprehensive and systematic understanding of the importance of automatic processing in emotion dysregulation.

Abstract
OBJECTIVE There is mixed evidence as to whether patients with obsessive-compulsive disorder (OCD) have excessive attentional engagement and emotional response to OCD-related stimuli in the environment. Here we investigate the occurrence of an attentional bias toward specific OCD-related stimuli and its relationship with obsessive-compulsive symptom dimensions. METHODS Forty-eight patients with OCD participated in an attentional bias task containing OCD- and non-OCD-related stimuli and had their performance compared with that of 24 age-, sex-, and education-matched healthy control subjects. Severity of obsessive-compulsive and comorbid depressive symptoms was assessed using the Obsessive-Compulsive Inventory-Revised and the Beck Depression Inventory, respectively. RESULTS Although there were significant and almost significant group effects on the reaction time (RT) toward OCD- and non-OCD-related figures, respectively, no difference between patients with OCD and controls was noted with regard to RT toward OCD-related figures minus RT toward non-OCD-related figures. Nevertheless, within the OCD group, partial correlational analysis controlled for age and severity of depression unveiled positive correlations between (1) obsessional symptoms and RT toward checking-related pictures and (2) ordering symptoms and RT toward ordering-related pictures. CONCLUSIONS The positive correlations between RT to content-specific stimuli and the severity of corresponding obsessive-compulsive symptoms suggest that patients with OCD experience difficulty in disengaging attention from personally salient stimuli.

Abstract
BACKGROUND Major depressive disorder (MDD), panic disorder, and social anxiety disorder are among the most prevalent and frequently co-occurring psychiatric disorders in adults and may be characterized by a common deficiency in processing of emotional information. METHODS We used functional magnetic resonance imaging during the performance of an emotional word encoding and recognition paradigm in patients with MDD (n = 51), comorbid MDD and anxiety (n = 59), panic disorder and/or social anxiety disorder without comorbid MDD (n = 56), and control subjects (n = 49). In addition, we studied effects of illness severity, regional brain volume, and antidepressant use. RESULTS Patients with MDD, prevalent anxiety disorders, or both showed a common hyporesponse in the right hippocampus during positive (>neutral) word encoding compared with control subjects. During negative encoding, increased insular activation was observed in both depressed groups (MDD and MDD + anxiety), whereas increased amygdala and anterior cingulate cortex activation during positive word encoding were observed as depressive state-dependent effects in MDD only. During recognition, anxiety patients showed increased inferior frontal gyrus activation. Overall, effects were unaffected by medication use and regional brain volume. CONCLUSIONS Hippocampal blunting during positive word encoding is a generic effect in depression and anxiety disorders, which may constitute a common vulnerability factor. Increased insular and amygdalar involvement during negative word encoding may underlie heightened experience of, and an inability to disengage from, negative emotions in depressive disorders. Our results emphasize a common neurobiological deficiency in both MDD and anxiety disorders, which may mark a general insensitiveness to positive information.

Abstract
Theoretical models of social phobia propose that biased attention contributes to the maintenance of symptoms; however these theoretical models make opposing predictions. Specifically, whereas Rapee and Heimberg (1997) suggested the biases are characterised by hypervigilance to threat cues and difficulty disengaging attention from threat, Clark and Wells (1995) suggested that threat cues are largely avoided. Previous research has been limited by the almost exclusive reliance on behavioural response times to experimental tasks to provide an index of attentional biases. The current study evaluated the relationship between the time-course of attention and symptoms of social anxiety and depression. Forty-two young adults completed a dot-probe task with emotional faces while eye-movement data were collected. The results revealed that increased social anxiety was associated with attention to emotional (rather than neutral) faces over time as well as difficulty disengaging attention from angry expressions; some evidence was found for a relationship between heightened depressive symptoms and increased attention to fear faces.

Abstract
The role of attentional biases in panic disorder has been well characterised. However, recent studies suggest an important effect of antidepressant and anxiolytic drugs on cognitive bias and most studies have included medicated patients in their sample. This study therefore examined cognitive bias in an untreated sample of participants with panic disorder (PD). A sample of 23 untreated participants with panic disorder with or without agoraphobia (PPD) and 22 healthy controls (HC) were tested with a Facial Expression Recognition task featuring different emotional intensities, a Faces Dot Probe task, a Self Beliefs task and an Emotional Stroop task. PPD showed exaggerated attentional biases to negative face and word stimuli in two different paradigms and endorsed more panic-related and negative self-attributions. They also showed enhanced perception of facial expressions of sadness. These tasks are sensitive to cognitive bias in a community-based sample of untreated PD participants. Attentional biases in panic disorder cannot be explained by the use of medication in this group and may therefore play a critical role in the underlying pathogenesis of the disorder.

Abstract
In this quantitative review, we examined the magnitude of attentional biases to negative stimuli in depression. Results from 29 empirical studies examining emotional Stroop or dot probe results in depressed participants (clinical depression, nonclinical dysphoria, and subjects undergoing depressive mood induction) were examined. Studies using the emotional Stroop task yielded marginally significant evidence of a difference between depressed and nondepressed samples, whereas those using the dot probe task showed significant differences between groups (d = 0.52). We found no evidence for significant moderation of these effects by age, sex, type of depressed sample, year of publication, stimulus presentation duration, or type of stimuli (verbal or nonverbal), although statistical power for these tests was limited. These results support the existence of biased attention to negative information in depression.

Abstract
Despite the frequent comorbidity of social anxiety disorder and alcohol use disorders, no theoretical model currently exists to explain the specific mechanisms underlying the comorbidity between these two disorders. An integration of existing theoretical models and empirical evidence across the social anxiety and alcohol use literatures is presented as the Avoidance-Coping Cognitive Model, which proposes that socially anxious individuals may be particularly vulnerable to the anxiolytic effects of alcohol through reductions in attention biases to social threat. The disproportionate reduction in anxiety may then make alcohol an attractive method of avoidance coping. Gaps in the empirical literature are reviewed in light of this model as future directions are suggested.

Abstract
OBJECTIVE To identify how psychiatric co-morbidity was identified and assessed, in studies of attentional bias in clinical samples of patients with alcohol use disorders (AUDs). DESIGN Systematic review methodology was used to identify studies and abstract data on alcohol-related attentional biases and measurement of psychiatric co-morbidity. RESULTS Seventeen papers were identified that met the criteria for inclusion. All but one study were in patients meeting criteria for alcohol dependence. In 10 of the 17 studies, either no mention or minimal statements were made pertaining to possible co-morbid conditions (including other substance use): five excluded patients with psychiatric diagnoses, (variously defined), and two excluded patients on 'psychotropic medication'. Slow response latencies to all word types were found in studies where co-morbid conditions were not considered. CONCLUSIONS Despite the high prevalence of psychiatric pathology in patients with AUDs (particularly depression), and the acknowledged impact that this has on aetiology, presentation and outcome, psychiatric co-morbidity has not been consistently measured or described in experimental studies on alcohol-related attentional biases in clinical samples. In order to have an accurate appreciation of the role of attentional biases in patients with AUDs, there needs to be a consistent approach to measuring the co-occurrence of other psychopathology. Further research is needed to assess the impact of co-morbidities on attentional biases in AUDs, to enable the development of more targeted psychological and pharmacological treatments.

Abstract
Prior research has often linked anxiety to attentional vigilance for threat using the dot probe task, which presents probes in spatial locations that were or were not preceded by a putative threat stimulus. The present study investigated the impact of worry on threat vigilance by administering this task during a worry condition and during a mental arithmetic control condition to 56 undergraduate students scoring in the low normal range on a measure of chronic worry. The worry induction was associated with faster responses than arithmetic to probes in the attended location following threat words, indicating the combined influence of worry and threat in facilitating attention. Within the worry condition, responses to probes in the attended location were faster for trials containing threat words than for trials with only neutral words, whereas the converse pattern was observed for responses to probes in the unattended location. This connection between worry states and attentional capture by threat may be central to understanding the impact of hypervigilance on information processing in anxiety and its disorders.

Social vision: sustained perceptual enhancement of affective facial cues in social anxiety. Neuroimage 2010; 54:1615-24. [PMID: 20832490 DOI: 10.1016/j.neuroimage.2010.08.080] [Citation(s) in RCA: 62] [Impact Index Per Article: 4.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/26/2010] [Revised: 08/26/2010] [Accepted: 08/31/2010] [Indexed: 12/21/2022] Open
Abstract
Heightened perception of facial cues is at the core of many theories of social behavior and its disorders. In the present study, we continuously measured electrocortical dynamics in human visual cortex, as evoked by happy, neutral, fearful, and angry faces. Thirty-seven participants endorsing high versus low generalized social anxiety (upper and lower tertiles of 2104 screened undergraduates) viewed naturalistic faces flickering at 17.5 Hz to evoke steady-state visual evoked potentials (ssVEPs), recorded from 129 scalp electrodes. Electrophysiological data were evaluated in the time-frequency domain after linear source space projection using the minimum norm method. Source estimation indicated an early visual cortical origin of the face-evoked ssVEP, which showed sustained amplitude enhancement for emotional expressions specifically in individuals with pervasive social anxiety. Participants in the low symptom group showed no such sensitivity, and a correlational analysis across the entire sample revealed a strong relationship between self-reported interpersonal anxiety/avoidance and enhanced visual cortical response amplitude for emotional, versus neutral expressions. This pattern was maintained across the 3500 ms viewing epoch, suggesting that temporally sustained, heightened perceptual bias towards affective facial cues is associated with generalized social anxiety.

Abstract
Attentional biases with regard to emotional facial expressions are associated with social anxiety in adults. We investigated whether similar relations exist in children. Seventy-nine 8- to 11-year-olds completed a probe detection task. On a given trial, 1 of 3 pairs of faces was presented: negative-neutral, negative-positive, and positive-neutral. The strongest association was between social anxiety symptoms and avoidance of negative faces from negative-neutral trials (r = - .32), with all other correlations less than half that size. This association was largely due to avoidance of angry and fearful expressions. These results provide preliminary evidence that anxiety is associated with attentional biases in children as in adults.

Abstract
Cognitive biases play an important role in the onset and maintenance of Social Anxiety Disorder (SAD). Few studies, however, have examined the role of comorbid Major Depressive Disorder (MDD) in the processing of emotional material. In addition, little is known about the relation among different cognitive biases. In the current study, 73 participants (54.79% female) completed an emotion face dot-probe task followed by a recognition memory test. Compared to participants with SAD, participants with comorbid SAD and MDD oriented away from supraliminally presented angry faces. Subsequently, SAD participants with and without comorbidity recognized fewer angry faces than non-disordered controls. Furthermore, attention biases for subliminally presented stimuli predicted recognition accuracy only for comorbid participants. These results suggest that the presence of comorbid MDD affects attentional orienting in SAD participants. In addition, it highlights the interconnectedness of attention and memory biases for comorbid participants.

Abstract
The present research examines whether forming implementation intentions can help people with social anxiety to control their attention and make more realistic appraisals of their performance. In Experiment 1, socially anxious participants (relative to less anxious participants) exhibited an attentional bias toward social threat words in a Visual Dot Probe task. However, socially anxious participants who formed implementation intentions designed to control attention did not exhibit this bias. Using a spatial cuing task, Experiment 2 showed that forming implementation intentions also promoted rapid disengagement from threatening stimuli. Experiment 3 ruled out the possibility that implementation intentions were effective merely because they provided additional goal-relevant information. In Experiment 4, participants gave a speech and subsequently rated their performance. Forming implementation intentions prevented the underestimation of performance that characterizes socially anxious individuals. Together, the findings suggest that forming implementation intentions may provide an effective means of handling self-regulatory problems in social anxiety.
