Substance use and the paradox of good and bad attentional bias.

Habitual substance use is associated with attentional bias for stimuli related to the use. The current study tested whether individuals’ substance use can be predicted from their attentional bias for concern-related and substance-related stimuli. Participants (N = 71; 54% male) were selected among university students and the community. The study was conducted in Iran, in which alcohol consumption is illegal. Participants completed a substance use questionnaire and classic, substance-, and concern-related Stroop tests. The results show that after controlling for demographic variables and classic Stroop interference, increases in substance-related but decreases in concern-related reaction times predicted the amount of substances that had been consumed by the participants. Individuals’ attentional bias for both substance-related and substance-unrelated goals may be important in predicting substance use behavior. The implication of the findings for treatment prognosis has been discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Alcohol-related attentional bias in problem drinkers with the flicker change blindness paradigm.

The authors used a flicker paradigm for inducing change blindness as a more direct method of measuring attentional bias in problem drinkers in treatment than the previously used, modified Stroop, Posner, and dual-task paradigms. First, in an artificially constructed visual scene comprising digitized photographs of real alcohol-related and neutral objects, problem drinkers detected a change made to an alcohol-related object more quickly than to a neutral object. Age- and gender-matched social drinkers showed no such difference. Second, problem drinkers given the alcohol-related change to detect showed a negative correlation between the speed with which the change was detected and the problem severity as measured by the number of times previously treated. Coupled with other data from heavy and light social drinkers, the data support a graded continuity of attentional bias underpinning the length of the consumption continuum.

Threat-related attentional bias in anxious and nonanxious individuals: A meta-analytic study.

This meta-analysis of 172 studies (N = 2,263 anxious,N = 1,768 nonanxious) examined the boundary conditions of threat-related attentional biases in anxiety. Overall, the results show that the bias is reliably demonstrated with different experimental paradigms and under a variety of experimental conditions, but that it is only an effect size of d = 0.45. Although processes requiring conscious perception of threat contribute to the bias, a significant bias is also observed with stimuli outside awareness. The bias is of comparable magnitude across different types of anxious populations (individuals with different clinical disorders, high-anxious nonclinical individuals, anxious children and adults) and is not observed in nonanxious individuals. Empirical and clinical implications as well as future directions for research are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Electrophysiological evidence of alcohol-related attentional bias in social drinkers low in alcohol sensitivity.

Low sensitivity to the acute effects of alcohol is a known risk factor for alcoholism. However, little is known concerning potential information-processing routes by which this risk factor might contribute to increased drinking. We tested the hypothesis that low-sensitivity (LS) participants would show biased attention to alcohol cues, compared with their high-sensitivity (HS) counterparts. Participants performed a task in which alcoholic and nonalcoholic beverage cues were presented bilaterally followed by a target that required categorization by color. Response times were faster for targets appearing in alcohol-cued than non–alcohol-cued locations for LS but not for HS participants. Event-related potential markers of early attention orienting (P1 amplitude) and subsequent attention reorienting (ipsilateral invalid negativity amplitude) indicated preferential selective attention to alcohol-cued locations among LS individuals. Controlling for recent drinking and family history of alcoholism did not affect these patterns, except that among HS participants, relatively heavy recent drinking was associated with difficulty reorienting attention away from alcohol-cued locations. These findings suggest a potential information-processing bias through which low sensitivity could lead to heavy alcohol involvement.

The reduction of anxiety vulnerability through the modification of attentional bias: A real-world study using a home-based cognitive bias modification procedure.

Recent laboratory work suggests that biased attentional responding to negative information causally impacts anxiety reactivity to a contrived laboratory stressor. However, it remains unknown whether such attentional bias contributes to real-world anxiety vulnerability. In the present study, the authors addressed this issue by experimentally inducing biased attentional response to emotionally negative stimuli, using a home-based attentional training program and then examining the influence of this attentional manipulation on trait anxiety scores and on state anxiety responses to a subsequent stressful life event. The attentional bias modification procedure was effective in inducing attentional avoidance of negative information. Furthermore, this attentional manipulation served to reduce trait anxiety scores and to attenuate state anxiety responses to the subsequent naturalistic stressor. These findings support the hypotheses that biased attentional responding to emotionally negative information contributes causally to real-world anxiety vulnerability.

A comparative study of drug-related attentional bias: Evidence from Iran.

The Addiction-Stroop test has been widely used to investigate the attentional correlates of alcohol and drug abuse; however, the majority of the studies have been conducted with European and American participants. The present study tested whether Iranian drug abusers show higher attentional bias for drug-related stimuli. Participants included drug abusers (N = 53; 100% male), with a clinical history of opium and heroin abuse, who were in a Methadone Maintenance Therapy program. Only nonabusers (N = 71; 71, 54% male) with a history of having never abused of drugs or alcohol participated in the study as controls. All participants completed a computerized Persian version of classic and addiction Stroop tests. The results of a multivariate analysis of covariance (MANCOVA) showed that drug abusers had a higher attentional bias for drug-related stimuli than nonabusers, after the effects of age and education had been controlled. The results of repeating the MANCOVA (a) limited to men only, and (b) to men and women in the nonabuser sample showed that the observed difference in the drug-related attentional bias of drug-abusers and nonabusers was not an artifact of gender imbalance. Our findings support the idea that drug-related attentional bias is culture-free. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Attentional Bias and Drinking to Cope With Social Anxiety.

This study investigated the sensitivity of the emotional Stroop test for identifying individuals who reported drinking to cope with social fears. Community volunteers completed a modified Stroop task during which social threat, alcohol-related, and control words were presented. High scores on drinking-to-cope measures were hypothesized to be associated with longer response latencies to both social threat and alcohol-related words. Consistent with previous studies, alcohol dependence was correlated with latencies for alcohol-related words, and level of social anxiety was correlated with response latency to social threat words. As expected, drinking-to-cope measures predicted response latency to alcohol-related and social threat words. These results suggest that the emotional Stroop test is useful in studying the relationship between social anxiety and alcohol consumption.

Drinking to cope and alcohol use and abuse in unipolar depression: A 10-year model.

This study examined drinking to cope with distress and drinking behavior in a baseline sample of 412 unipolar depressed patients assessed 4 times over a 10-year period. Baseline drinking to cope operated prospectively as a risk factor for more alcohol consumption at 1-, 4, and 10-year follow-ups and for more drinking problems at 1- and 4-year follow-ups. Findings elucidate a key mechanism in this process by showing that drinking to cope strengthened the link between depressive symptoms and drinking behavior. Individuals who had a stronger propensity to drink to cope at baseline showed a stronger connection between depressive symptoms and both alcohol consumption and drinking problems.

Mood-induced shifts in attentional bias to emotional information predict ill- and well-being.

Previous research has suggested that biased attention toward emotional (typically threatening) stimuli contributes to ill-being (e.g., high levels of anxiety), but its contribution to well-being is less clear. The researchers assessed naturalistic shifts in attentional bias toward threatening and pleasant schematic face cues in response to five induced mood states in college students. They also assessed state anxiety and satisfaction with life concurrently and 3 weeks later. Controlling for concurrent anxiety, a fear-induced shift in attention to threatening cues was associated with increased levels of later anxiety. Controlling for concurrent life satisfaction, a happiness-induced shift in attention to emotional cues (both threatening and pleasant) was associated with increased levels of later life satisfaction. These results suggest that mood-induced changes in deployment of attention to emotional information may accumulate in ways that impact psychological functioning, yet these effects depend on mood state and the emotional cues afforded by the context.

Malleability of attentional bias for positive emotional information and anxiety vulnerability.

Recent research supports a causal link between attentional bias for negative emotional information and anxiety vulnerability. However, little is known about the role of positive emotional processing in modulating anxiety reactivity to stress. In the current study, we used an attentional training paradigm designed to experimentally manipulate the processing of positive emotional cues. Participants were randomly assigned to complete a computerized probe detection task designed to induce selective processing of positive stimuli or to a sham condition. Following training, participants were exposed to a laboratory stressor (i.e., videotaped speech), and state anxiety and positive affect in response to the stressor were assessed. Results revealed that individual variability in the capacity to develop an attentional bias for positive information following training predicted subsequent emotional responses to the stressor. Moreover, individual differences in social anxiety, but not depression, moderated the effects of the attentional manipulation, such that, higher levels of social anxiety were associated with diminished attentional allocation toward positive cues. The current findings point to the potential value of considering the role of positive emotional processing in anxiety vulnerability. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Effects of smoking opportunity on attentional bias in smokers.

The emotional Stroop task was used to examine the influence of opportunity to smoke on attentionall bias to smoking-related stimuli. At the outset of the study, 92 nicotine-deprived smokers were told that they (a) would, (b) would not, or (c) might be able to smoke during the experiment. Next, participants completed an emotional Stroop task, in which they were presented with smoking-related or -unrelated words in an unblocked format. Smokers demonstrated interference to the smoking words, relative to matched neutral words, F(1, 87)?=?18.0, p?F(2, 87)?=?4.35, p?     

A meta-analytic investigation of the relationship between attentional bias and subjective craving in substance abuse.

Theoretical models of addiction suggest that attentional bias for substance-related cues should be associated with self-reported craving. The authors evaluated the strength of the association by performing a meta-analysis on 68 independent data sets from which correlation coefficients between subjective craving and attentional bias indices were derived. Additional stratified analyses were conducted to identify any variables that might moderate the association between craving and attentional bias. The primary meta-analysis indicated a significant, albeit weak (r = .19), association between attentional bias and craving. Stratified analyses revealed that the association was larger for illicit drug and caffeine craving than for alcohol and tobacco craving, larger for direct measures of attention (eye movement measures and event-related potential measures) than for indirect behavioral measures of attentional bias, and larger when craving strength was high than when it was low (all ps     

Clinical implications of attentional bias in anxiety disorders: An integrative literature review.

Research on information processing biases has been motivated by the hope that it would lead to new and more efficient psychotherapeutic interventions. The literature is abundant with empirical data of attentional biases toward threat stimuli in anxiety disorders. This article aims to review the existing literature on the topic of attentional bias in anxiety disorders and discuss important implications for clinical practice. We adopted an integrative approach to link research data on attentional bias, information processing, and cognitive accounts (automaticity and controllability) with clinical practice in cognitive-behavioral therapy. It is important to develop and apply therapeutic interventions that can effectively reduce negative attentional biases while treating the main problems associated with anxiety disorders. However, it remains to be seen whether cognitive therapy interventions targeting more voluntary, strategic information processing can have a positive impact on automatic, involuntary processing involved in attentional biases.

What's in a name? Attachment-related attentional bias.

Participants completed a dot probe task that presented pairs of first names: the participant's own name and a neutral name (Experiments 1-4), the name of their attachment figure and a neutral name (Experiments 1-4), or the name of a known person and a neutral name (Experiments 2-4). A significant attentional bias effect was found for the attachment name in attachment-related contexts, whether they were threatening or positive. The results of Experiments 2 and 4 showed that the attentional bias effects for the attachment name were not driven by familiarity effects and could not be interpreted in terms of salience. Attachment anxiety was associated with hypervigilance toward the attachment name in threatening and positive attachment contexts. Attachment avoidance was unrelated to any attentional bias effects.

Observational fear conditioning in the acquisition and extinction of attentional bias for threat: An experimental evaluation.

Anxious persons show automatic and strategic attentional biases for threatening information. Yet, the mechanisms and processes that underlie such biases remain unclear. The central aim of the present study was to elucidate the relation between observational threat learning and the acquisition and extinction of biased threat processing by integrating emotional Stroop color naming tasks within an observational differential fear conditioning procedure. Forty-three healthy female participants underwent several consecutive observational fear conditioning phases. During acquisition, participants watched a confederate displaying mock panic attacks (UCS) paired with a verbal stimulus (CS+), but not with a second nonreinforced verbal stimulus (CS-). As expected, participants showed greater magnitude electrodermal and verbal-evaluative (e.g., distress, fear) conditioned responses to the CS+ over the CS- word. Participants also demonstrated slower color-naming latencies to CS+ compared to the CS- word following acquisition and showed attenuation of this preferential processing bias for threat following extinction. Findings are discussed broadly in the context of the interplay between fear learning and processing biases for threat as observed in persons suffering from anxiety disorders.

Attentional bias to threat: A perceptual accuracy approach.

To investigate attentional bias to threatening information, the authors propose a new version of the spatial cueing paradigm in which the focus is on perceptual accuracy instead of response speed. In two experiments, healthy volunteers made unspeeded discriminations between three visual targets presented left or right. Each target was preceded by a visual cue (colored rectangle) at either the same (valid) or opposite (invalid) location. By means of differential classical conditioning with aversive white noise, a threat cue and a control cue were created. Analyses of error rates showed that cueing effects (lower proportion of errors in valid trials relative to invalid trials) were more pronounced in threat trials than in neutral trials. This threat-related bias was particularly because of threat cues reducing accuracy in invalid trials, indicating difficulty disengaging attention from threatening information. Engagement of attention was not affected by threat, as threat cues did not facilitate the processing of targets in valid trials. The findings are discussed in light of the strengths and limitations of spatial cueing tasks. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

A Combi-Stroop test for measuring food-related attentional bias.

There are methodological complexities with the supraliminal–lexical versions of the modified versions of the Stroop tests that could be responsible for inconsistencies across the literature (Field & Cox, 2008). We tested whether a combination of subliminal–pictorial and classic Stroop tests can differentiate between dieters' and nondieters' food attentional bias (FAB). Participants were dieters (n = 30) and nondieters (n = 32) who were tested 3 hr after having a meal. Each picture from among 24 high-calorie and 24 low-calorie food pictures was presented for 32 ms before the appearance of a congruent or an incongruent color word, in response to which participants were required to manually report, via a tagged keyboard, the correct color of the word as quickly and accurately as possible. Color-naming latencies and interference scores were calculated. Dieters showed the highest reaction times to incongruent color words following high-calorie food pictures; overall, dieters showed significantly higher FABs than nondieters. The Combi-Stroop test has differential validity. Moreover, findings suggest that FAB can result from early allocation of dieters' attention to food-related stimuli.

Drinking to cope as a statistical mediator in the relationship between suicidal ideation and alcohol outcomes among underage college drinkers.

Etiological models of alcohol use that highlight the role of negative affect and depression have not been applied to the association of suicidality and alcohol use. The authors examined whether a motivational model of alcohol use could be applied to understand the relationship between suicidal ideation and alcohol outcomes in a sample of underage college drinkers who had a history of passive suicidal ideation (n = 91). In this cross-sectional study, regression analyses were conducted to examine whether drinking to cope with negative affect statistically mediated or was an intervening variable in the association between suicidal ideation and alcohol outcomes. Results revealed that drinking to cope was a significant intervening variable in the relationships between suicidal ideation and alcohol consumption, heavy episodic drinking, and alcohol problems, even while controlling for depression. These results suggest that the relationship between suicidal ideation and alcohol outcomes may be due to individuals using alcohol to regulate or escape the distress associated with suicidal ideation. Consideration of alcohol-related models can improve the conceptualization of research on suicidality and alcohol use. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Effects of social support visibility on adjustment to stress: Experimental evidence.

Previous fieldwork has suggested that visible social support can entail an emotional cost and that a supportive act is most effective when it is accomplished either (a) outside of recipients' awareness or (b) within their awareness but with sufficient subtlety that they do not interpret it as support. To investigate the latter phenomenon, the authors conducted 3 experiments in which female participants were led to expect a stressful speech task and a confederate peer provided support in such a way that it was either visible or invisible (N=257). Invisible support (practical and emotional) reduced emotional reactivity relative to visible and no support. Visible support was either ineffective or it exacerbated reactivity. Explanatory analyses indicated that support was effective when it avoided communicating a sense of inefficacy to recipients. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Fitting in and feeling fine: Conformity and coping motives as mediators of the relationship between social anxiety and problematic drinking.

The present research was conducted to clarify the relationships among social anxiety, alcohol consumption, alcohol-related problems, and negative-reinforcement drinking motives among college students. Heavy drinking students (N = 316, 53.80% female) completed self-report measures of social anxiety, alcohol consumption, alcohol-related problems, and drinking motives. Findings indicated that students higher in social anxiety consumed less alcohol but experienced more negative consequences. Moreover, the relationship between social anxiety and negative consequences was mediated by coping and conformity drinking motives in addition to alcohol consumption. In the context of social anxiety, the current research demonstrates the importance of examining problematic drinking as distinct constructs: alcohol consumption and negative consequences. Findings are also discussed in terms of implications for interventions with socially anxious students. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
