Attentional bias predicts outcome in smoking cessation.

Most attempts to quit smoking end in failure, with many quitters relapsing in the first few days. Responses to smoking-related cues may precipitate relapse. A modified emotional Stroop task-which measures the extent to which smoking-related words disrupt performance on a reaction time (RT) task-was used to index the distracting effects of smoking-related cues. Smokers (N=158) randomized to a high-dose nicotine patch (35 mg) or placebo patch completed the Stroop task on the 1st day of a quit attempt. Smokers using an active patch exhibited less attentional bias, making fewer errors on smoking related words. Smokers who showed greater attentional bias (slowed RT on the first block of smoking words) were significantly more likely to lapse in the short-term, even when controlling for self-reported urges at the test session. Attentional bias measures may tap an important component of dependence. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The Effect of Tobacco Abstinence on Recognition Memory, Digit Span Recall, and Attentional Vigilance.

This article examines the effects of tobacco abstinence on recognition memory, digit span recall, and visual attentional vigilance. The results demonstrated that abstinence impaired recognition memory discrimination (ad libitum d' = .85, abstinent d' = .64), recognition memory hit rates (ad libitum = .60, abstinent = .54), accuracy of target detection in attentional vigilance (ad libitum = .99, abstinent = .97), and speed of target detection in attentional vigilance (ad libitum = 662 ms, abstinent = 687 ms). Abstinence did not impair digit span recall (ad libitum = .55, abstinent = .56). These results are consistent with the hypotheses that tobacco abstinence impairs episodic memory and sustained attention. They also suggest that some, but not necessarily all, short-term memory processes may not be influenced by tobacco abstinence. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Attentional bias for craving-related (chocolate) food cues.

In this study, we investigated attentional biases for craving-related food cues. A pictorial dot probe task was used to assess selective attentional processing of one particular highly desired food, namely chocolate, relative to that of other highly desired foods. In Experiment 1, we examined biased processing of chocolate cues in habitual (trait) chocolate cravers, whereas in Experiment 2 we investigated the effect of experimentally induced (state) chocolate cravings on such processing. As predicted, habitual chocolate cravers (Experiment 1) and individuals in whom a craving for chocolate was temporarily induced (Experiment 2) showed speeded detection of probes replacing chocolate-related pictures, demonstrating an attentional bias for chocolate cues. Subsequent examination indicated that in both experiments the observed attentional biases stemmed from difficulty in disengaging attention from chocolate cues rather than from a shift of attention toward such cues. The findings have important theoretical and practical implications. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Attentional bias for smoking and affective stimuli: A Stroop task study.

Prior research has demonstrated attentional biases to smoking-related cues among smokers, and several lines of research suggest strong ties between smoking and negative affect. The authors tested attentional biases to both smoking and affective cues in 27 smokers using an emotional Stroop paradigm, and examined the relationship between these forms of attentional bias. Findings indicated significant attentional biases to smoking-related and negative-affect words, but not positive-affect words. In addition, there was a significant correlation between the degree of attentional bias to smoking and negative-affect words. These data provide evidence of a close association between smoking-related and affective cue processing from a cognitive perspective. Potential theoretical and clinical implications for these findings are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

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.

Psychiatric disorders in smokers seeking treatment for tobacco dependence: Relations with tobacco dependence and cessation.

Objective: The present research examined the relation of psychiatric disorders to tobacco dependence and cessation outcomes. Method: Data were collected from 1,504 smokers (58.2% women; 83.9% White; mean age = 44.67 years, SD = 11.08) making an aided smoking cessation attempt as part of a clinical trial. Psychiatric diagnoses were determined with the Composite International Diagnostic Interview structured clinical interview. Tobacco dependence was assessed with the Fagerstr?m Test of Nicotine Dependence (FTND) and the Wisconsin Inventory of Smoking Dependence Motives (WISDM). Results: Diagnostic groups included those who were never diagnosed, those who had ever been diagnosed (at any time, including in the past year), and those with past-year diagnoses (with or without prior diagnosis). Some diagnostic groups had lower follow-up abstinence rates than did the never diagnosed group (ps OR = .72, p = .02) and those ever diagnosed with more than one psychiatric diagnosis (OR = .74, p = .03) had lower abstinence rates. The diagnostic categories did not differ in smoking heaviness or the FTND, but they did differ in dependence motives assessed with the WISDM. Conclusion: Information on recent or lifetime psychiatric disorders may help clinicians gauge relapse risk and may suggest dependence motives that are particularly relevant to affected patients. These findings also illustrate the importance of using multidimensional tobacco dependence assessments. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Attentional biases for threatening faces in children: Vigilant and avoidant processes.

The authors examined the processing of threat-related information in childhood anxiety with the emotional Stroop task and the dot probe task. In study 1, a nonclinical sample of 112 pupils (mean age = 9 years) performed pictorial versions of both tasks. For each task, an index indicating a bias for threat processing was computed. Positive correlations were found between these indices and anxiety. When compared with the original emotional Stroop index, the absolute value of the emotional Stroop index was a better predictor of anxiety. It was possible to replicate this result in study 2 with 80 pupils (mean age = 8.6 years). Results are discussed with regard to vigilance and avoidance as basic mechanisms underlying performance on the tasks. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

A Controlled Study of a Cigarette Smoking Cessation Intervention for Adolescents in Substance Abuse Treatment.

Tobacco use is prevalent among youth with alcohol and other drug problems, yet this issue has received limited research and clinical attention. This study reports on a controlled evaluation of a cigarette smoking intervention with 54 adolescents in treatment for substance abuse, ages 13-18 (22% female). Participants were assessed at 4 time points. A greater proportion of participants in the treatment condition (n = 26) reported cessation attempts and point abstinence than did control participants (n = 28) at all time points. However, significant differences were found only for point abstinence at a 3-month follow-up. These findings provide initial support for the efficacy of a smoking cessation intervention delivered in the context of adolescent substance abuse treatment.

Attentional asymmetry in schizophrenia: Disengagement and inhibition of return deficits.

This research examined 2 components of visual orienting in medicated schizophrenia patients: the validity effect and the inhibition of return (IOR). In the 1st experiment, patients showed the expected asymmetry in orienting attention, that is, larger validity effect in the right visual field than in the left. However, this asymmetry was due to a deficit in facilitatory processes rather than a disengagement deficit. In addition, patients showed a deficit in IOR. In the 2nd experiment, a 2nd central cue for summoning attention, explicitly, back to the center was used. In this experiment, normal IOR in schizophrenia patients was found. Because it was shown that schizophrenia patients do not have a disengagement deficit, IOR possibly could not be observed because of the increased facilitation in that location. It was proposed that the abnormality in visual attention in schizophrenia is due to a deficit in inhibitory processes. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Contingencies for change in complacent smokers.

The majority of smokers have no plans to quit in the near future. These complacent smokers are less likely to quit than other smokers, and few interventions are known to reduce smoking in this population. Although monetary incentives can reduce complacent smokers' breath carbon monoxide (BCO) levels, it is not clear whether these effects can be sustained beyond the several weeks that past studies have examined. The authors compared complacent smokers randomly assigned to receive incentives for BCO reductions (n = 18) or noncontingent incentives (n = 19) for 3 months. Contingent incentives were associated with (a) reduced BCO; (b) more BCO samples indicative of abstinence; (c) fewer cigarettes smoked and more days abstinent at study end; and (d) lower salivary cotinine. These behaviors can predict future cessation, and 2 of the 18 smokers (11%) receiving BCO-contingent incentives reported quitting as compared with none in the control group. Contingency management procedures, such as those used here, may effectively promote cessation among complacent smokers and provide a model for understanding the possible effects of some environmental interventions (like workplace smoking bans) on the behavior of complacent smokers.

Can(not) take my eyes off it: Attention bias for food in overweight participants.

Objective: The aim of the current study was to investigate attention biases for food cues, craving, and overeating in overweight and healthy-weight participants. Specifically, it was tested whether attention allocation processes toward high-fat foods differ between overweight and normal weight individuals and whether selective attention biases for food cues are related to craving and food intake. Method: Eye movements were recorded as a direct index of attention allocation in a sample of 22 overweight/obese and 29 healthy-weight female students during a visual probe task with food pictures. In addition, self-reported craving and actual food intake during a bogus “taste-test” were assessed. Results: Overweight participants showed an approach-avoidance pattern of attention allocation toward high-fat food. Overweight participants directed their first gaze more often toward food pictures than healthy-weight individuals, but subsequently showed reduced maintenance of attention on these pictures. For overweight participants, craving was related to initial orientation toward food. Moreover, overweight participants consumed significantly more snack food than healthy-weight participants. Conclusion: Results emphasize the importance of identifying different attention bias components in overweight individuals with regard to craving and subsequent overeating.

Detected, selected, and sometimes neglected: cognitive processing of cues in addiction.

It is proposed that potential drug cues are evaluated preattentively, are prioritized, and subsequently trigger somatovisceral, behavioral, and cognitive responses. Throughout, this information processing is subjected to automatized attentional and interpretative biases. These processes can enhance subjective awareness of physiological arousal, action tendencies, and cognitions, but can also be inhibitory. Accordingly, different components of cue reactivity do not gain equal access to the limited processing resources necessary to generate experience of craving.

Environments as cues to smoke: Implications for human extinction-based research and treatment.

Animal research has shown that the environments, or contexts, in which drug use occurs can play a key role in how animals respond to drug-related cues. Less is known about the role of environmental contexts in human drug-dependence research. Traditionally, cue-based studies and treatments focus on conditioned cues most proximal to drug administration (e.g., lit cigarettes, pictorial stimuli of drug paraphernalia). However, there is reason to believe that more distal cues, such as the environments in which drugs were previously used, might similarly gain associative control over human responding. This article describes a body of systematic research aimed at identifying and studying the impact of environmental contexts on smokers' cue reactivity in the laboratory. Overall, results of this program of research demonstrate that exposure to environments associated with smoking, but completely devoid of proximal smoking cues, can function as conditioned stimuli capable of evoking strong subjective responding from abstinent smokers. Furthermore, more robust reactivity can be achieved if environmental context cues are personalized using novel techniques described in this article.

Relation between childhood disruptive behavior disorders and substance use and dependence symptoms in young adulthood: Individuals with symptoms of attention-deficit/hyperactivity disorder are uniquely at risk.

Most prior literature examining the relations among attention-deficit/hyperactivity disorder (ADHD), conduct disorder (CD), and substance use and abuse suggests that CD fully accounts for the ADHD-substance abuse relation. This study sought to test an alternate theory that individuals with symptoms of both ADHD and CD are at a special risk for substance abuse. Relations between childhood ADHD and CD symptoms, and young adult tobacco, alcohol, marijuana, and hard drug use and dependence symptoms, were examined in a sample of 481 young adults. ADHD and CD symptoms interacted to predict marijuana dependence symptoms and hard drug use and dependence symptoms, such that individuals with high levels of both ADHD and CD had the highest levels of these outcomes.
