Abstract
Whilst opportunities to participate in gambling have increased, access to support for problem gamblers is lacking behind. This lack of balance calls for improved and accessible intervention methods. The present double-blind randomized controlled trial (RCT) explored the effectiveness of two interventions targeting automatic cognitive processes, known as Attentional Bias Modification (AtBM) and Approach Bias Modification (ApBM). It was hypothesized these interventions would reduce gambling behavior and reduce or reverse targeted biases. Participants (N = 331) were community-recruited Flemish (35%) and Dutch (65%) adult problem gamblers motivated to reduce or stop their gambling who received either six sessions of active training (AtBM or ApBM) or of the corresponding sham-training (sham-AtBM or sham-ApBM). Due to high attrition rates (90.1% up to the intervention phase) the study was terminated before completion, since it would greatly limit the validity of any results. A post hoc qualitative study was performed on a subset of participants to gain insight into contributing factors for the high attrition rate. Issues negatively impacting participants' motivation to complete the program were identified, as well as elements of the program that received approval. The results from this study provide a first insight into the potential of the use of online cognitive bias modification (CBM) interventions in problem gambling (PG). Suggestions and directions for future studies are discussed.

Abstract
RATIONALE Win-paired stimuli can promote risk taking in experimental gambling paradigms in both rats and humans. We previously demonstrated that atomoxetine, a noradrenaline reuptake inhibitor, and guanfacine, a selective α2A adrenergic receptor agonist, reduced risk taking on the cued rat gambling task (crGT), a rodent assay of risky choice in which wins are accompanied by salient cues. Both compounds also decreased impulsive premature responding. OBJECTIVE The key neural loci mediating these effects were unknown. The lateral orbitofrontal cortex (lOFC) and the medial prefrontal cortex (mPFC), which are highly implicated in risk assessment, action selection, and impulse control, receive dense noradrenergic innervation. We therefore infused atomoxetine and guanfacine directly into either the lOFC or prelimbic (PrL) mPFC prior to task performance. RESULTS When infused into the lOFC, atomoxetine improved decision making score and adaptive lose-shift behaviour in males, but not in females, without altering motor impulsivity. Conversely, intra-PrL atomoxetine improved impulse control in risk preferring animals of both sexes, but did not alter decision making. Guanfacine administered into the PrL, but not lOFC, also altered motor impulsivity in all subjects, though in the opposite direction to atomoxetine. CONCLUSIONS These data highlight a double dissociation between the behavioural effects of noradrenergic signaling across frontal regions with respect to risky choice and impulsive action. Given that the influence of noradrenergic manipulations on motor impulsivity could depend on baseline risk preference, these data also suggest that the noradrenaline system may function differently in subjects that are susceptible to the risk-promoting lure of win-associated cues.

Abstract
INTRODUCTION Empirical studies have demonstrated the role that attentional bias, the mutual excitatory relationship between attentional bias and craving, and mentalizing play in problem gambling. Although problem gambling rates among older-aged adults have steadily increased in recent years, research studies among this cohort are scarce. The present study is the first to empirically investigate attentional bias, as well as the joint role of attentional bias, craving, and mentalizing among older-aged gamblers. METHOD Thirty-six male older-aged gamblers were administered the South Oaks Gambling Screen (SOGS), the Gambling Craving Scale (GACS), and the Reflective Functioning Questionnaire (RFQ-8) to assess gambling severity, craving levels, and mentalizing, respectively. Participants also performed a modified Posner Task to investigate attentional biases. RESULTS Hierarchical linear regression analysis showed that among older-aged male gamblers, GACS Anticipation and RFQ-8 Uncertainty about mental states, as well as disengagement bias at 100 ms, significantly predicted gambling severity. CONCLUSION The present study provides the first empirical support for the role of attentional bias, craving, and mentalizing among older-aged gambling. More specifically, a difficult in disengaging attention away from gambling, the anticipation of pleasure deriving from gambling, and hypomentalizing predicted gambling severity among older-aged gamblers. The findings make an important contribution, by identifying the factors responsible for problem gambling among this specific age cohort and suggesting that timely interventions for mentalizing and attentional bias may be necessary to prevent problem gambling in old age.

Abstract
Gambling disorder (GD) is a behavioural addiction characterized by impairments in decision-making, favouring risk- and reward-prone choices. One explanatory factor for this behaviour is a deviation in attentional processes, as increasing evidence indicates that GD patients show an attentional bias toward gambling stimuli. However, previous attentional studies have not directly investigated attention during risky decision-making. 26 patients with GD and 29 healthy matched controls (HC) completed a mixed gambles task combined with eye-tracking to investigate attentional biases for potential gains versus losses during decision-making under risk. Results indicate that compared to HC, GD patients gambled more and were less loss averse. GD patients did not show a direct attentional bias towards gains (or relative to losses). Using a recent (neuro)economics model that considers average attention and trial-wise deviations in average attention, we conducted fine-grained exploratory analyses of the attentional data. Results indicate that the average attention for gains in GD patients moderated the effect of gain value on gambling choices, whereas this was not the case for HC. GD patients with high average attention for gains started gambling at less high gain values. A similar trend-level effect was found for losses, where GD patients with high average attention for losses stopped gambling at lower loss values. This study gives more insight into how attentional processes in GD play a role in gambling behaviour, which could have implications for the development of future treatments focusing on attentional training or for the development of interventions that increase the salience of losses.

Abstract
Previous research has identified attentional biases towards addiction-related stimuli, including gambling-related stimuli. Eye-tracking is considered the gold standard methodology for measuring attentional biases, yet no review to date has examined its use in measuring gambling-related attentional biases. This systematic review synthesized the literature using eye-tracking to examine attentional biases among people who gamble. We reviewed articles from Web of Science and PubMed that were published from 1990 to 2021. A total of 11 articles were included, with sample sizes ranging from 38 to 173 participants. Of these studies, seven examined attentional biases for gambling-related visual stimuli. These seven studies provided support that gambling can result in the development of an attentional bias for gambling-related stimuli. With respect to correlates of gambling-related attentional biases, there were mixed results. Some studies identified significant positive associations between gambling-related attentional biases and psychosocial variables, such as problem gambling severity, gambling expectancies, gambling cravings, gambling motives, depressive symptom severity, alcohol use severity, daily stress, affective impulsivity, and immersion. Four studies examined attentional biases for responsible gambling messaging and advertisements, finding that both people who do and do not gamble attend less to responsible gambling messaging compared to other types of information such as the betting odds. Research using eye-tracking to examine attentional biases among people who gamble is in its infancy. Yet, the preliminary results support the identification of attentional biases using the gold-standard methodology. Further studies are needed to examine the correlates and potential clinical utility of assessing gambling-related attentional biases using eye-tracking.

Do pupillary responses during authentic slot machine use reflect arousal or screen luminance fluctuations? A proof-of-concept study. PLoS One 2022; 17:e0272070.

Abstract
Modern slot machines are among the more harmful forms of gambling. Psychophysiological measures may provide a window into mental processes that underpin these harms. Here we investigated pupil dilation derived from eye tracking as a means of capturing changes in sympathetic nervous system arousal following outcomes on a real slot machine. We hypothesized that positively reinforcing slot machine outcomes would be associated with increases in arousal, reflected in larger pupil diameter. We further examined the contribution of game luminance fluctuations on pupil diameter. In Experiment 1A, experienced slot machine gamblers (N = 53) played a commercially-available slot machine in a laboratory for 20 minutes while wearing mobile eye tracking glasses. Analyses differentiated loss outcomes, wins, losses-disguised-as-wins, and (free-spin) bonus features. Bonus features were associated with rapid increases in pupil diameter following the onset of outcome-related audiovisual feedback, relative to losses. In Experiment 1B, luminance data were extracted from captured screen videos (derived from Experiment 1A) to characterize on-screen luminance changes that could modulate pupil diameter. Bonus features and wins were associated with pronounced and complex fluctuations in screen luminance (≈50 L and ≈25L, respectively). However, the pupil dilation that was observed to bonus features in Experiment 1A coincided temporally with only negligible changes in screen luminance, providing partial evidence that the pupil dilation to bonus features may be due to arousal. In Experiment 2, 12 participants viewed pairs of stimuli (scrambled slot machine images) at luminance difference thresholds of ≈25L, ≈50L, and ≈100L. Scrambled images presented at luminance differences of ≈25L and greater were sufficient to cause pupillary responses. Overall, pupillometry may detect event-related changes in sympathetic nervous system arousal following gambling outcomes, but researchers must pay careful attention to substantial in-game luminance changes that may confound arousal-based interpretations.

Abstract
BACKGROUND AND AIMS Attentional bias to gambling-related stimuli is associated with increased severity of gambling disorder. However, the addiction-related moderators of attentional bias among those who gamble are largely unknown. Impulsivity is associated with attentional bias among those who abuse substances, and we hypothesized that impulsivity would moderate the relationship between disordered electronic gaming machine (EGM) gambling and attentional bias. METHODS We tested whether facets of impulsivity, as measured by the UPPS-P (positive urgency, negative urgency, sensation seeking, lack of perseverance, lack of premeditation) and the Barratt Impulsiveness Scale-11 (cognitive, motor, non-planning) moderated the relationship between increased severity of gambling disorder, as measured by the Problem Gambling Severity Index (PGSI), and attentional bias. Seventy-five EGM players participated in a free-viewing eye-tracking paradigm to measure attentional bias to EGM images. RESULTS Attentional bias was significantly correlated with Barratt Impulsiveness Scale-11 (BIS-11) motor, positive urgency, and negative urgency. Only positive and negative urgency moderated the relationship between PGSI scores and attentional bias. For participants with high PGSI scores, higher positive and negative urgency were associated with larger attentional biases to EGM stimuli. DISCUSSION The results indicate that affective impulsivity is an important contributor to the association between gambling disorder and attentional bias.

Abstract
INTRODUCTION This study examined attentional bias (AB) to e-cigarette cues among a sample of non-smoking daily e-cigarette users (n = 27), non-smoking occasional e-cigarette users (n = 32), and control participants (n = 61) who did not smoke or use e-cigarettes. The possibility that e-cigarette users develop a transference of cues to traditional cigarettes was also examined. METHODS AB was assessed using a free-viewing eye-gaze tracking methodology, in which participants viewed 180 pairs of images for 4 seconds (e-cigarette and neutral image, e-cigarette and smoking image, smoking and neutral image). RESULTS Daily and occasional e-cigarette users attended to pairs of e-cigarette and neutral images equally, whereas non-users attended to neutral images significantly more than e-cigarette images. All three groups attended to e-cigarette images significantly more than smoking images, with significantly larger biases for e-cigarette users. There were no between-group differences in attention to pairs of smoking and neutral images. A moderation analysis indicated that for occasional users but not daily users, years of vaping reduced the bias toward neutral images over smoking images. CONCLUSIONS Taken together, the results indicate that e-cigarette users exhibit heighted attention to e-cigarettes relative to non-users, which may have implications as to how they react to e-cigarette cues in real-world settings. AB for e-cigarettes did not transfer to traditional cigarette cues, which indicates that further research is required to identify the mechanisms involved in the migration of e-cigarettes to traditional cigarettes. IMPLICATIONS This study is the first attempt to examine attentional biases for e-cigarette cues among non-smoking current e-cigarette users using eye-gaze tracking. The results contribute to the growing literature on the correlates of problematic e-cigarette use and indicate that daily and occasional e-cigarette use is associated with attentional biases for e-cigarettes. The existence of attentional biases in e-cigarette users may help to explain the high rate of failure to quit e-cigarettes and provides support for the utility of attentional bias modification in the treatment of problematic e-cigarette use.

Abstract
Lottery gambling can become an addictive behavior which can significantly interfere with daily functioning. The objectives of this work were to estimate the prevalence of lottery gambling, to assess the profile related to this gambling type in a large clinical sample of patients who met criteria for gambling disorder (GD), and to compare this profile with the other two non-strategic forms of gambling (slot-machines and bingo). Sample included n = 3,531 patients consecutively attended for treatment-seeking due to gambling-related problems. All the participants met criteria for GD and were into the range of 18 to 85 years old. Sociodemographic variables, GD severity, psychopathological state, and personality traits were assessed. Statistical comparisons between the groups defined by the patients’ gambling preference (lotteries versus other gambling activities) were conducted, with chi-square test and analysis of variance. The prevalence of lotteries as the only gambling activity was 2.5%, 8.9% for lottery gambling as primary activity with other secondary gambling types, and 20.6% for lotteries as primary or secondary gambling activity. Lottery gambling and bingo gambling were more prevalent among women (bingo included the highest percentage of women). Compared to slot machine gambling, lotteries and bingo grouped older patients and those with later age of onset of the gambling-related problems. Bingo gambling showed the highest psychological distress and the most dysfunctional personality traits. This study shows the high frequency of lottery gambling among treatment-seeking for GD patients, and it provides empirical evidence about the profile associated with this gambling activity compared to other non-strategic gambling forms. The likelihood of lottery gambling is higher for women, patients married or living with a stable partner, and those within higher social position indexes.

Abstract
Online sports gambling is a popular recreational activity. Using the Theory of Planned Behaviour as the theoretical foundation, the aim of this study was to examine for differences between gamblers and non-gamblers in terms of their attitudes, subjective norms and perceived behavioral control towards online sports gambling. 173 male students from a tertiary educational institution were recruited for this study of which 56 respondents (32%) were gamblers. A series of regression analysis revealed differences between gamblers and non-gamblers. While subjective norms and perceived behavioural control were significant predictors of gambling intentions for the gamblers group, only attitude was a significant predictor for the non-gamblers group. Further analysis showed that subjective norms had a larger effect on the gamblers group in comparison to the non-gamblers group. Physiological data from an eye tracker provided further empirical evidence that there were differences between gamblers and non-gamblers. Gamblers, perhaps because they are more familiar with gambling websites, take less time to process information. The findings from this study suggests that there are differences between gamblers and non-gamblers. To prevent problem gambling, there is a need to develop different communication messages for gamblers and non-gamblers.

Abstract
In the field of psychology, the merge of decision-theory and neuroscientific methods produces an array of scientifically recognized paradigms. For example, by exploring consumer’s eye-movement behavior, researchers aim to deepen the understanding of how patterns of retinal activation are being meaningfully transformed into visual experiences and connected with specific reactions (e.g., purchase). Notably, eye-movements provide knowledge of one’s homeostatic balance and gatekeep information that shape decisions. Hence, vision science investigates the quality of observed environments determined under various experimental conditions. Moreover, it answers questions on how human process visual stimuli and use gained information for a successful strategy to achieve certain goals. While capturing cognitive states with the support of the eye-trackers progresses at a relatively fast pace in decision-making research, measuring the visual performance of real-life tasks, which require complex cognitive skills, is tentatively translated into clinical experiments. Nevertheless, the potential of the human eye as a highly valuable source of biomarkers has been underlined. In this article, we aim to draw readers attention to decision-making experimental paradigms supported with eye-tracking technology among clinical populations. Such interdisciplinary approach may become an important component that will (i) help in objectively illustrating patient’s models of beliefs and values, (ii) support clinical interventions, and (iii) contribute to health services. It is possible that shortly, eye-movement data from decision-making experiments will grant the scientific community a greater understanding of mechanisms underlining mental states and consumption practices that medical professionals consider as obsessions, disorders or addiction.

Impulsivity, Emotion Regulation, Cognitive Distortions and Attentional Bias in a Spanish Sample of Gambling Disorder Patients: Comparison between Online and Land-Based Gambling. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph18094869. [PMID: 34063619 PMCID: PMC8124317 DOI: 10.3390/ijerph18094869] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 03/30/2021] [Revised: 04/23/2021] [Accepted: 04/30/2021] [Indexed: 12/02/2022]
Abstract
Several risk factors have been related to the onset and maintenance of gambling disorder (GD). The aim of this study was to explore the differences in emotion dysregulation, impulsivity, cognitive distortions, and attentional bias between online and land-based gamblers. The sample consisted of 88 treatment-seeking patients from the Behavioral Addictions Unit at the Hospital de la Santa Creu i Sant Pau, Barcelona (Spain). Patients were divided into two groups by considering their main type of gambling, i.e., online (n = 26) and land-based gambling (n = 62). Online gamblers were younger, more often employed, with a higher educational level than land-based gamblers. Regarding the rest of the variables, statistically significant differences were only found in Positive Urgency, one of the UPPS-P subscales, in which the land-based gambling group scored higher than the online gambling group. In this exploratory study, individuals with online and land-based GD phenotypes did not differ either in difficulties in emotion regulation or in attentional and cognitive biases. However, land-based GD patients showed a higher tendency to succumb to strong impulses under the influence of positive emotions. These preliminary findings warrant the need to continue investigating GD phenotypes in larger patient samples.

Maurage P, Bollen Z, Masson N, D'Hondt F. Eye Tracking Studies Exploring Cognitive and Affective Processes among Alcohol Drinkers: a Systematic Review and Perspectives. Neuropsychol Rev 2020; 31:167-201.

Abstract
Acute alcohol intoxication and alcohol use disorders are characterized by a wide range of psychological and cerebral impairments, which have been widely explored using neuropsychological and neuroscientific techniques. Eye tracking has recently emerged as an innovative tool to renew this exploration, as eye movements offer complementary information on the processes underlying perceptive, attentional, memory or executive abilities. Building on this, the present systematic and critical literature review provides a comprehensive overview of eye tracking studies exploring cognitive and affective processes among alcohol drinkers. Using PRISMA guidelines, 36 papers that measured eye movements among alcohol drinkers were extracted from three databases (PsycINFO, PubMed, Scopus). They were assessed for methodological quality using a standardized procedure, and categorized based on the main cognitive function measured, namely perceptive abilities, attentional bias, executive function, emotion and prevention/intervention. Eye tracking indexes showed that alcohol-related disorders are related to: (1) a stable pattern of basic eye movement impairments, particularly during alcohol intoxication; (2) a robust attentional bias, indexed by increased dwell times for alcohol-related stimuli; (3) a reduced inhibitory control on saccadic movements; (4) an increased pupillary reactivity to visual stimuli, regardless of their emotional content; (5) a limited visual attention to prevention messages. Perspectives for future research are proposed, notably encouraging the exploration of eye movements in severe alcohol use disorders and the establishment of methodological gold standards for eye tracking measures in this field.

[PMID: 32553393 DOI: 10.1016/j.jad.2020.03.144] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/24/2019] [Revised: 02/14/2020] [Accepted: 03/29/2020] [Indexed: 10/24/2022]
Abstract
BACKGROUND Previous research has emphasized the importance of attentional bias in the maintenance of both adult and adolescent disordered gambling. There is a substantial body of empirical evidence demonstrating facilitated attention and difficulty in disengagement from gambling stimuli among disordered gamblers, but no study has ever experimentally investigated the association between attentional bias and risk-taking behavior in gambling. The aim of the present study was to examine the interrelationship between attentional bias for gambling stimuli, risk-taking attitude, and severity of gambling involvement. METHODS The present study recruited 70 male adults from gambling venues to participate in the experiment. Gambling severity, attentional bias, and risk-taking were assessed utilizing the South Oaks Gambling Screen, the Modified Posner Task, and the Balloon Analogue Risk Task, respectively. RESULTS Disordered gamblers showed greater readiness to detect gambling stimuli and took more risks than non-disordered gamblers. Regression analysis showed that being of a young age, automatic facilitated attention for gambling cues, and risk-proneness significantly predicted problem gambling. Additionally, a path analysis was performed to test if automatic facilitated attention towards gambling was on the path from risk-taking to gambling severity, or if risk-taking mediated the impact of facilitation biases on gambling severity. The results indicated that attentional bias predicted gambling severity both directly and indirectly via risk-taking. LIMITATIONS The modest sample size and the absence of female gamblers limited the generalizability of the results. CONCLUSIONS The present findings are compatible with the view that an automatic detection of gambling stimuli is responsible for greater riskiness that, in turn, fosters gambling problems.

Investigating immersion in slot machine gambling using mobile eye-tracking. Addiction 2020; 115:1127-1138. [PMID: 31746072 DOI: 10.1111/add.14899] [Citation(s) in RCA: 23] [Impact Index Per Article: 5.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/15/2019] [Revised: 07/12/2019] [Accepted: 11/08/2019] [Indexed: 12/11/2022]
Abstract
BACKGROUND AND AIMS Immersion during slot machine gambling has been linked to disordered gambling. Current conceptualizations of immersion (namely dissociation, flow and the machine zone) make contrasting predictions as to whether gamblers are captivated by the game per se ('zoned in') or motivated by the escape that immersion provides ('zoned out'). We examined whether selected eye-movement metrics can distinguish between these predictions. DESIGN AND SETTING Pre-registered, correlational analysis in a laboratory setting. Participants gambled on a genuine slot machine for 20 minutes while wearing eye-tracking glasses. PARTICIPANTS Fifty-three adult slot machine gamblers who were not high-risk problem gamblers. MEASUREMENTS We examined self-reported immersion during the gambling session and eye movements at different areas of the slot machine screen (the reels, the credit window, etc.). We further explored these variables' relationships with saccade count and amplitude. FINDINGS The ratio of dwell time on the game's credit window relative to the game's reels was positively associated with immersion (t(51) = 1.68, P = 0.049 one-tailed, R2 = 0.05). Follow-up analyses described event-related changes in these patterns following different spin outcomes. CONCLUSIONS Immersion while gambling on a slot machine appears to be associated with active scanning of the game and a focus on the game's credit window. These results are more consistent with a 'zoned in' account of immersion aligned with flow theory than a 'zoned out' account based on escape.

From sign-tracking to attentional bias: Implications for gambling and substance use disorders. Prog Neuropsychopharmacol Biol Psychiatry 2020; 99:109861.

Abstract
Sign-tracking behavior in Pavlovian autoshaping is known to be a relevant index of the incentive salience attributed to reward-related cues. Evidence has accumulated to suggest that animals that exhibit a sign-tracker phenotype are especially vulnerable to addiction and relapse due to their proneness to attribute incentive salience to drug cues, and their relatively weak cognitive and attentional control over their behavior. Interestingly, sign-tracking is also influenced by reward uncertainty in a way that may promote gambling disorder. Research indicates that reward uncertainty sensitizes sign-tracking responses and favors the development of a sign-tracker phenotype, compatible with the conditioned attractiveness of lights and sounds in casinos for problem gamblers. The study of attentional biases in humans (an effect akin to sign-tracking in animals) leads to similar observations, notably that the propensity to develop attraction for conditioned stimuli (CSs) is predictive of addictive behavior. Here we review the literature on drug addiction and gambling disorder, highlighting the similarities between studies of sign-tracking and attentional biases.

Abstract
Internet addiction and Internet gaming disorders are increasingly prevalent. Whilst there has been much focus on the use of conventional psychological approaches in the treatment of individuals with these addictive disorders, there has also been ongoing research exploring the potential of cognitive bias modification amongst individuals with Internet and gaming addiction. Some studies have documented the presence of cognitive biases and the effectiveness of bias modification for Internet addiction and gaming disorders. However, there have not been any reviews that have synthesized the findings related to cognitive biases for Internet addiction and Internet gaming disorders. It is important for us to undertake a scoping review as an attempt to map out the literature for cognitive biases in Internet addiction and gaming disorders. A scoping review was undertaken, and articles were identified using a search through the following databases: PubMed, MEDLINE, and PsycINFO. Six articles were identified. There were differences in the methods of ascertaining whether an individual has an underlying Internet or gaming addiction, as several different instruments have been used. With regards to the characteristics of the cognitive bias assessment task utilized, the most common task used was that of the Stroop task. Of the six identified studies, five have provided evidence documenting the presence of cognitive biases in these disorders. Only one study has examined cognitive bias modification and provided support for its effectiveness. Whilst several studies have provided preliminary findings documenting the presence of cognitive biases in these disorders, there remains a need for further research evaluating the effectiveness of bias modification, as well as the standardization of the diagnostic tools and the task paradigms used in the assessment.

Interest in inducements: A psychophysiological study on sports betting advertising. Int J Psychophysiol 2019; 147:100-106.

Abstract
Recent research has shown an association between the viewing of wagering advertising, which often presents inducements to gamble, and maladaptive sports-betting behaviours; however, the mechanism/s underlying the development of the intention to gamble remains relatively understudied. Eye-tracking and tonic electrodermal activity was recorded from 59 participants (including 49 regular gamblers and 10 non-gamblers), while they watched a series of advertisements. Following each advertisement, participants were asked to rate how likely they would be to take up the offer presented, therein. The number of fixations placed on each offer differed according to the type of inducement shown (p < .001), with reduced risk and cash back inducements being looked at more often than better odds and bonus bet inducements by all groups. Increased electrodermal activity while viewing the advertisements was associated with greater severity of gambling-related harm (p < .001), as well as greater ratings of desire for most advertisements. Rating of desire was, likewise, positively associated with gambling-related harm (p < .001). These results may suggest that, while the offers in gambling advertisements may be looked at by most viewers, unless there an attendant increase in arousal, it is quite unlikely that these inducements will elicit a desire to gamble. For individuals already at risk of gambling problems, exposure to these advertisements, especially those offering what is perceived to be safer betting options that minimise financial losses, may exacerbate existing harms. Such information may prove useful in guiding industry practice, government regulations, therapeutic interventions, and future research on this topic.

Facilitated attention for gambling cues in adolescent problem gamblers: An experimental study. J Affect Disord 2019; 252:39-46.

Abstract
BACKGROUND Studies investigating attentional biases in gambling have observed that problem gamblers' attention is biased toward gambling cues. Despite the increase of gambling among adolescents, to date, no study has ever examined the role of attentional bias in adolescent gambling, as well as the relationships between adolescent gambling severity, craving, and alcohol use. METHODS The present study comprised 87 adolescent participants. Based on South Oaks Gambling Screen Revised for Adolescents (SOGS-RA) scores, participants were assigned to non-problem or problem gamblers groups. Participants performed a modified Posner Task (with cue presentation times at 100 and 500 ms) to assess attentional biases. Following the experiment, participants completed the Gambling Craving Scale (GACS) and the Alcohol Use Disorders Identification Test (AUDIT). RESULTS Compared to non-problem gamblers, problem gamblers displayed facilitation bias for gambling cues at 500 ms and reported higher levels of craving and alcohol consumption. Results also indicated that alcohol use correlated with facilitation bias. LIMITATIONS The recruitment of a predominantly male sample and the use of an indirect measure of attentional bias may have affected the findings concerning attentional processes. CONCLUSIONS The present study provides the first empirical evidence of attentional processes in adolescent gambling, and confirms the role of attentional biases, craving, and alcohol use being associated factors in adolescent problem gambling. The results of the present study stress the importance of attentional biases in the initial stages of problem gambling and suggest the need for clinical interventions aimed at reducing attentional bias before they became automatic. Overall, the present study stressed the role of attentional bias as both facilitator and a consequence of gambling involvement.

Abstract
Gambling disorder is an impairing condition confounded by psychiatric co-morbidity, particularly with substance use and anxiety disorders. Yet, our knowledge of the mechanisms that cause these disorders to coalesce remains limited. The Incentive Sensitization Theory suggests that sensitization of neural "wanting" pathways, which attribute incentive salience to rewards and their cues, is responsible for the excessive desire for drugs and cue-triggered craving. The resulting hyper-reactivity of the "wanting' system is believed to heavily influence compulsive drug use and relapse. Notably, evidence for sensitization of the mesolimbic dopamine pathway has been seen across gambling and substance use, as well as anxiety and stress-related pathology, with stress playing a major role in relapse. Together, this evidence highlights a phenomenon known as cross-sensitization, whereby sensitization to stress, drugs, or gambling behaviors enhance the sensitivity and dopaminergic response to any of those stimuli. Here, we review the literature on how cue attraction and reward uncertainty may underlie gambling pathology, and examine how this framework may advance our understanding of co-mordidity with substance-use disorders (e.g., alcohol, nicotine) and anxiety disorders. We argue that reward uncertainty, as seen in slot machines and games of chance, increases dopaminergic activity in the mesolimbic pathway and enhances the incentive value of reward cues. We propose that incentive sensitization by reward uncertainty may interact with and predispose individuals to drug abuse and stress, creating a mechanism through which co-mordidity of these disorders may emerge.

Abstract
There is evidence that training addicted participants to implicitly avoid disorder-related stimuli by using a training version of the Approach-Avoidance Task (AAT) results in reduced substance consumption (i.e., Approach Bias Modification [AppBM]). The aim of the present web-based study was to investigate the feasibility and effectiveness of AppBM in reducing gambling-related symptoms. A self-selected sample of participants with problem/pathological slot-machine gambling completed an online survey and received either AppBM or Sham training (final N = 131). Attrition during study participation was high (66%). In both conditions slot-machine related and neutral pictures were presented. Within the AppBM condition all slot-machine related pictures had to be pushed and all neutral pictures had to be pulled, whereas in the Sham condition the contingency was 50:50. Eight weeks after baseline, participants were re-assessed. Both groups showed a similar reduction in gambling-related symptoms. Findings are at odds with the hypothesis claiming that only contingency trainings yield beneficial effects. However, it cannot be ruled out that effects result from other factors unrelated to training such as expectancy effects. We think this study holds valuable information how to conduct larger trials in the future and may prove helpful to improve training and its delivery.

Abstract
Background Substance use disorders are highly prevalent globally. Relapse rates following conventional psychological interventions for substance use disorders remain high. Recent reviews have highlighted attentional and approach or avoidance biases to be responsible for multiple relapses. Other studies have reported the efficacy of interventions to modify biases. With advances in technologies, there are now mobile versions of conventional bias modification interventions. However, to date, no study has evaluated bias modification in a substance-using, non-Western sample. Existing evaluations of mobile technologies for the delivery of bias interventions are also limited to alcohol or tobacco use disorders. Objective This study aims to examine the feasibility of mobile-based attention bias modification intervention among treatment-seeking individuals with substance use and alcohol use disorders. Methods This is a feasibility study, in which inpatients who are in their rehabilitation phase of clinical management will be recruited. On each day that they are in the study, they will be required to complete a craving visual analogue scale and undertake both a visual probe-based assessment and and modification task in a smartphone app . Reaction time data will be collated for the computation of baseline attentional biases and to determine whether there is a reduction of attentional bias across the interventions. Feasibility will be determined by the number of participants recruited and participants’ adherence to the planned interventions up until the completion of their rehabilitation program and by the ability of the app in detecting baseline biases and changes in biases. Acceptability of the intervention will be assessed by a short questionnaire of users’ perceptions of the intervention. Statistical analyses will be performed using SPSS version 22.0, while qualitative analysis of the perspectives will be performed using NVivo version 10.0. Results This study was approved by the National Healthcare Group Domain Specific Research Board, with approval number (2018/00316). Results will be disseminated by means of conferences and publications.Currently, we are in the process of recruitment for this study. Conclusions To the best of our knowledge, this is the first study to evaluate the feasibility and acceptability of a mobile attention bias modification intervention for individuals with substance use disorders. The data pertaining to the feasibility and acceptability are undoubtedly crucial because they imply the potential use of mobile technologies in retraining attentional biases among inpatients admitted for medical-assisted detoxification and rehabilitation. Participants’ feedback pertaining to the ease of use, interactivity, and motivation to continue using the app is crucial because it will determine whether a codesign approach might be warranted to design an app that is acceptable for participants and that participants themselves would be motivated to use.

Abstract
BACKGROUND Anorectal disorders are progressively increasing in the society. Out of many of the causes, some important are sedentary lifestyle, irregular and inappropriate diet, prolonged sitting or standing, and certain psychological disturbances. The prime cause of anorectal disorders is the instability of Jatharagni (digestive system), which further leads to constipation. AIM AND OBJECTIVE To compare the efficacy of Apamarga Kshara application (AKA) and sclerotherapy (SCL) in the management of Arsha (1st and 2nd degree piles). MATERIALS AND METHODS In this study, 50 patients of Arsha (1st and 2nd degree piles) were selected and randomly allocated into two groups. In group AKA (n = 25), Apamarga Tikshna Kshara (alkaline of Achyranthes aspera linn.) application was done and in group SCL (n = 25), SCL was done in 1st and 2nd degree piles. The study was open prospective interventional clinical trial. Patients were assessed for relief in signs and symptoms at weekly interval for a month and another 1 month as follow-up period. RESULTS Patients of group SCL took more time than the patients of group AKA to get reduction in size of pile mass. In group SCL, maximum relief in bleeding as well as discharge per rectum was reported. AKA provided better results in ceasing the bleeding per rectum as well as reducing prolapse piles, than SCL. CONCLUSION The study concluded that AKA is a effective procedure of choice for the management of 1st and 2nd degree internal piles as compared to SCL.
