Objective: Abnormal selective attention to drug cues and negative affect is observed in patients with substance dependence, and it is closely associated with drug addiction and relapse. Methadone maintenance is an effective replacement therapy to treat heroin addiction, which significantly reduces the relapse rate. The present study examines whether the patients with opioid use disorder on chronic methadone maintenance therapy exhibit abnormal attentional bias to drug cues and negative-affective cues. Moreover, its relation to therapeutic and neuropsychological factors is also examined.Methods: Seventy-nine patients with opioid use disorder under chronic methadone maintenance therapy and 73 age-, sex-, and education-matched healthy controls were recruited and assessed for attentional bias to drug cues and negative affect using a dot-probe detection task. Correlational analysis was used to examine the relationships between the attentional bias and the demographic, therapeutic, and neuropsychological factors.Results: No significant overall patient-control group difference is observed in drug-related or negative-affective-related attentional bias scores. In the patient group, however, a significant negative correlation is found between the attentional bias scores to negative-affective cues and the duration of methadone treatment (p = 0.027), with the patients receiving longer methadone treatment showing less attentional avoidance to negative-affective cues. A significant positive correlation is found between the negative affect-induced bias and the impulsivity score (p = 0.006), with more impulsive patients showing higher attentional avoidance to negative affective cues than less impulsive patients. Additionally, the patients detect a smaller percentage of probe stimuli following the drug (p = 0.029) or negative-affective pictures (p = 0.009) than the healthy controls.Conclusion: The results of the present study indicate that the patients under chronic methadone maintenance therapy show normalized attentional bias to drug and negative-affective cues, confirming the involuntary attention of the patients is not abnormally captured by external drug or negative-affective clues. Our findings also highlight that the attentional avoidance of negative-affective cues is modulated by the duration of methadone treatment and the impulsivity level in the patients.

Abstract Attentional bias toward health-threat may theoretically contribute to the development and maintenance of health anxiety, but the empirical findings have been controversial. This study aimed to synthesize and explore the heterogeneity in a health-threat related attentional bias of health-anxious individuals, and to determine the theoretical model that better represents the pattern of attentional bias in health anxiety. Four databases (Web of Science, PubMed, PsycINFO, and Scopus) were searched for relevant studies, with 17 articles (N = 1546) included for a qualitative review and 16 articles (18 studies) for a three-level meta-analysis (N = 1490). The meta-analytic results indicated that the health anxiety group, compared to the control group, showed significantly greater attentional bias toward health-threat (g = 0.256). Further analyses revealed that attentional bias type, paradigm, and stimuli type were significant moderators. Additionally, compared to the controls, health-anxious individuals displayed significantly greater attention maintenance (g = 0.327) but nonsignificant attention vigilance to health-threat (g = −0.116). Our results provide evidence for the attention maintenance model in health-anxious individuals. The implications for further research and treatment of elevated health anxiety in the context of coronavirus disease-2019 (COVID-19) were also discussed.

Background Smoking is a global health threat. Attentional bias influences smoking behaviors. Although attentional bias retraining has shown benefits and recent advances in technology suggest that attentional bias retraining can be delivered via smartphone apps, there is a paucity of research on this topic. Objective This study aims to address this gap by exploring the use of attentional bias retraining via a novel smartphone app using a mixed methods pilot study. In the quantitative phase, it is hypothesized that participants in the training group who undertake attentional bias retraining via the app should have decreased levels of attentional bias, subjective craving, and smoking frequency, compared with those in the control group who do not undertake attentional bias retraining. The qualitative phase explores how the participants perceive and experience the novel app. Methods In all, 10 adult smokers (3 females and 7 males) between the ages of 26 and 56 years (mean 34.4 years, SD 9.97 years) were recruited. The participants were randomly allocated to the training and control groups. In weeks 1 and 3, participants from both groups attempted the standard visual probe task and rated their smoking frequency and subjective craving. In week 2, the participants in the training group attempted the modified visual probe task. After week 3, participants from both groups were interviewed about their views and experiences of the novel app. Results The results of the quantitative analysis did not support this study’s hypothesis. The qualitative data were analyzed using thematic analysis. The results yielded 5 themes: ease, helpfulness, unhelpful aspects, barriers, and refinement. Conclusions Findings from the qualitative study were consistent with those from previous studies on health-related smartphone apps. The qualitative results were helpful in understanding the user perspectives and experiences of the novel app, indicating that future research in this innovative area is necessary.

Objectives The current study investigated the role of maternal child- and self-oriented injustice appraisals about child pain in understanding maternal attention for child pain and adult anger cues and pain-attending behavior. Methods Forty-four children underwent a painful cold pressor task (CPT) while their mother observed. Eye tracking was used to measure maternal attention to child pain and adult anger cues. Initial attention allocation and attentional maintenance were indexed by probability of first fixation and gaze duration, respectively. Maternal pain-attending behaviors toward the child were videotaped and coded after CPT completion. Mothers also rated the intensity of pain and anger cues used in the free-viewing tasks. All analyses controlled for maternal catastrophizing about child pain. Results Neither child-oriented nor self-oriented injustice was associated with maternal attentional bias toward child pain. Regarding attention toward self-relevant anger cues, differential associations were observed for self- and child-oriented injustice appraisals, with maternal self-oriented injustice being associated with a greater probability of first fixating on anger and with higher anger ratings, whereas maternal child-oriented injustice was associated with enhanced attentional maintenance toward anger. Neither type of maternal injustice appraisals was associated with maternal pain-attending behavior, which was only associated with maternal catastrophizing. Conclusions The current study sheds light on potential differential mechanisms through which maternal self- vs. child-oriented injustice appraisals may exert their impact on parent and child pain-related outcomes. Theoretical implications and future directions are discussed.

Existing tasks assessing substance-related attentional biases are characterized by low internal consistency and test–retest reliability. This study aimed to assess the psychometric properties of a novel dual-probe task to measure alcohol-related attentional bias. Undergraduate students were recruited in June 2019 (N = 63; final N = 57; mean age = 20.88, SD = 2.63, 67% females). In the dual-probe task, participants were presented with simultaneous visual streams of adverts promoting either alcoholic or non-alcoholic drinks, and probes were presented in both streams. The dual-probe task measured the percentage of accurately identified probes that appeared on alcohol adverts in relation to total accuracy. The dual-probe task displayed excellent split-half reliability (M = 0.90, SD = 0.11; α = 0.90; 95% CI [0.84, 0.93]), and the derived attentional bias measure was significantly positively associated with beer drinking in a taste-test (r (57) = 0.33, p = 0.013; 95% CI [0.07, 0.54]), with habitual drinking (r (57) = 0.27, p = 0.045; 95% CI [0.01, 0.49]), and with increased craving (r (57) = 0.29, p = 0.031; 95% CI [0.03, 0.51]). Thus, the dual-probe task assessed attentional bias with excellent internal consistency and was associated with laboratory and habitual drinking measures, demonstrating initial support for the task’s utility in addiction research.

<p>New Zealand obesity rates have reached epidemic proportions. Excessive eating not only harms individual health, but also the NZ economy; health-related costs soar with rising obesity rates. The need to understand possible mechanisms driving excessive eating behaviour is now crucial. One cognitive mechanism thought to contribute to excessive eating is an attentional bias towards food stimuli. We propose this bias would be similar to the attentional bias that is consistently shown with emotional stimuli (e.g. erotic and mutilation images). In this thesis I examined attentional biases towards food stimuli and how they relate to both state (hunger) and trait (waist circumference) factors. In Experiment 1, I investigated the existence of a food-related attentional bias and whether this bias is stronger towards high calorie food images, compared to low-calorie and non-food images (household objects). Participants were asked to fast for 2 hours (to promote self-reported hunger) before completing a distraction task. This task has repeatedly shown an attentional bias to high arousal emotional images (erotic and mutilation scenes). On each trial, participants had to determine whether a target letter was a ‘K’ or an ‘N’, while ignoring centrally-presented distractors (high calorie, low calorie and household object images). Compared to scrambled images, all image types were similarly distracting. We found no support for the existence of an attentional bias towards food stimuli; nor did we find a significant association between the bias and either state or trait factors. Experiment 2 sought to conceptually replicate Cunningham & Egeth (2018) who found significant support for the existence of a food-related attentional bias. Participants completed a similar task. However, distractor relevance was manipulated by incorporating both central and peripheral distractors, to increase ecological validity. Additionally, participants were asked to fast for longer (4 hours) to increase self-reported hunger. Despite a significant distraction effect (participants were more distracted on distractor present vs. distractor absent trials) and distractor-location effect (participants were more distracted by central vs. peripheral distractors), participants did not exhibit an attentional bias towards food stimuli. Furthermore, no significant associations between the bias and either state or trait factors were found. Thus, food stimuli do not appear to rapidly capture attention the way that emotional stimuli do, at least not in this task. Future research is needed to clarify the role of cognitive mechanisms in excessive eating behaviour.</p>
