attentional bias drug addiction

Dean A.C. et al. Patients with cocaine dependence and PTSD, as compared to patients with only cocaine addiction and control participants, showed excessive cue reactivity to both drug- and trauma-related visual stimuli. Despite a somewhat higher attentional bias at baseline in the training group (mean difference = 9.80), this was not statistically significant, t(47) = 1.75, ns. (2008). Request PDF | On Jan 1, 2010, Matt Field and others published Attentional Bias to Drug Cues | Find, read and cite all the research you need on ResearchGate. Stroop tests tend to show subjects with anxiety disorders are more easily distracted and more prone to attentional bias. 2014 September; 3(3): e18669. Attentional Bias to Drug- and Stress-Related Pictorial Cues in Cocaine Addiction Comorbid with Posttraumatic Stress Disorder. This impacts not only the things that we perceive in the environment but the decisions that we make based upon our perceptions. Most profound differences were found in the amplitude and latency of frontal P3a, and centro-parietal P3b ERP components. The attentional bias involves the tendency to pay attention to some things while simultaneously ignoring others.

Attentional bias (AB) is hypothesized to have a causal contribution to substance abuse, addiction development and, maintenance. Journal of Neurotherapy: Vol. At baseline, the sample did not exhibit a significant attentional bias toward smoking cues, t(48) = 0.46, not significant (ns). 12, No. Chapter. They reported that bias retraining did not result in a reduction in attentional biases and that there was no impact of bias retraining on cravings. Attentional bias and drug taking. Journal of Neurotherapy: Vol. Further, attentional bias was reduced in both groups after therapy, independent of treatment condition. Keywords: addiction, drug, Stroop test, attentional bias Iran has the highest number of narcotics abusers in the world per capita (2.8% of the population; United Nations, 2005) and regardless of the governmental efforts, drug abuse is still increasing among the population, particularly the young (Sarami & Ghomashchi, 2003). Because drug stimuli produce conditioned responses that may motivate drug taking, biased attention toward these cues may play an important role in drug use and relapse following treatment. In synthesizing the findings regarding attentional bias and cue-induced craving, we suggest that MBIs may restructure attentional bias away from drug-related reinforcing stimuli (e.g., drug-cues, negative affective stimuli) and facilitate the addict’s attempts to deal with associated cravings. 12, No. A consistent feature of addiction is the attentional bias for drug-related stimuli (eg, drug paraphernalia). (2008). This study provides a systematic review of the effectiveness of ABM interventions in decreasing symptoms of addictive behaviour, taking baseline levels of attentional bias and changes in attentional bias into account. We conducted a meta-analysis examining randomized controlled trials (RCTs) of CBM for substance addiction outcomes. A common type of Attentional Bias is one in which two conditions can be present (see the example below), meaning there are four possible outcomes. Drug-related attentional bias appears to implicate the countermanding forces of cognitive control and reward salience. No significant correlation between attentional bias and drug use behaviors (total years, days in past 30 days and age to start cocaine use) was observed in cocaine-dependent subjects. 4, pp. Transcranial direct current stimulation (tDCS) has been of increasing interest in the past few years as a means for modulating neuroplasticity of the human brain. However, CET does not specifically reduce attentional bias. The most commonly used task is a modified version of the classic “Stroop” task. In addiction, a hyper-attentive state may develop towards drug-related cues, characterised as an attention bias to such cues. What Exactly Is an Attentional Bias? Perceptual preferences for drug-linked stimuli are an essential element within the neurobiology of addiction. Basic cognitive neuroscience research suggests that ignoring emotionally evocative stimuli in our environment requires both up-regulation of control networks and down-regulation of processing in emotion and reward regions. Background and Aims Cognitive bias modification (CBM) interventions, presumably targeting automatic processes, are considered particularly promising for addictions. (2019) examined attentional bias modification amongst 42 methamphetamine-dependent clients who were receiving residential treatment for their drug use. ABSTRACT Aims Attentional bias for drug‐related cues has been associated with drug maintenance and relapse. As drug seeking, drug procurement, and drug use rise to the top of one’s motivational priorities, one develops attentional bias toward words, symbols, and images linked to these substances. 4, pp. did not find a relationship between attentional bias and drug use history in cocaine-dependent subjects. Current Concepts and State of Knowledge . The noradrenaline system has been critically implicated in both attentional and response inhibitory processes and is directly affected by drugs such as cocaine. Attentional bias scores are presented in Table 1. Because the attentional bias might propel the person to use the substance, an intervention might help modify it. Objectives: The purpose of this article is to critically evaluate the following claims derived from contemporary theoretical models of attentional bias (AB) for food- and drug-related stimuli: (a) AB is a characteristic feature of obesity and addiction, (b) AB predicts future behavior, (c) AB exerts a causal influence on consummatory behavior, and (d) AB reflects appetitive motivational processes. Rationale: Biased attention towards drug-related cues and reduced inhibitory control over the regulation of drug-intake characterize drug addiction. Methods Studies were identified through systematic searches in bibliographical databases. 205-225. In this study, we investigated first whether pre-treatment impulsivity and attentional bias predict treatment outcome; next whether the drug modafinil given as an add-on treatment to cognitive behavioural therapy (CBT) improves impulsivity and attentional bias; and last, whether changes in impulsivity and attentional bias are related to improvements in treatment outcome. Drug dependence produces an attentional bias for the drug in question, causing addicted individuals to fixate on stimuli related to the substance in question. As predicted by numerous theoretical models, drug abusers have an attentional bias for drug-related pictures and words. Attentional biases also develop for stimuli that have been paired with nondrug rewards in adults without a history of addiction, the magnitude of which is predicted by visual working-memory capacity and impulsiveness. Attentional biases for drug-related stimuli play a prominent role in addiction, predicting treatment outcomes. 205-225. doi: 10.1080/10874200802502185 Geeky Definition of Attentional Bias: Attentional Bias causes people not to examine all possible outcomes when making judgements.In other words, their attention is on just one or two of the possible outcomes. Similarly, Hester et al. Objectives: The purpose of this article is to critically evaluate the following claims derived from contemporary theoretical models of attentional bias (AB) for food-and drug-related stimuli: (a) AB is a characteristic feature of obesity and addiction, (b) AB predicts future behavior, (c) AB exerts a causal influence on consummatory behavior, and (d) AB reflects appetitive motivational processes. Attentional Bias to Drug- and Stress-Related Pictorial Cues in Cocaine Addiction Comorbid with Posttraumatic Stress Disorder. Int J High Risk Behav Addict. A greater understanding of the mechanisms directing of attention towards salient stimuli, termed attentional bias, may help elucidate the mechanisms involved in the motivation smoke, and the motivation to drink in problem drinkers. For people with substance use disorder, exposure to drugs or things that remind them of drugs can trigger drug craving, which can sabotage efforts to stop using. When you are trying to make an important decision, do you always consider all of the possibilities? “Researchers have found that people who have eating disorders tend to pay more attention to stimuli related to food, while individuals experiencing drug addictions tend to be hyper-sensitive to drug-related cues. Journal Attentional bias is one of the most studied cognitive processes in addiction. Drug and Alcohol Dependence , 67(2), pp.185-191. DOI: 10.5812/ijhrba.18669 Published online 2014 August 26. Attentional bias modification (ABM) interventions have been developed to address addiction by reducing attentional bias for substance-related cues. Attentional Bias for Nondrug Reward Is Magnified in Addiction Brian A. Anderson, Monica L. Faulkner, Jessica J. Rilee, Steven Yantis, and Cherie L. Marvel Johns Hopkins University Attentional biases for drug-related stimuli play a prominent role in addiction, predicting treatment outcomes. Measurement. The performance of drug users on the Stroop task and visual dot-probe task has been interpreted as demonstrating attentional bias toward drug cues specific to an individual’s drug use history. For example, with regard to addiction, one influential model argues that attentional bias simply represents an output of the underlying neurobiological adaptations that drive drug-seeking behaviour (Robinson & Berridge, 1993). Conclusions Attentional bias may tap an important component of drug dependence as it is a predictor of opiate relapse. In this article, we discuss techniques that have been developed to help people overcome their attentional bias for alcohol, smoking-related stimuli, drugs, or unhealthy food. Comparing attentional bias to smoking cues in current smokers, former smokers, and non-smokers using a dot-probe task. The rest are ignored.
