Abstract
Identification of specific patterns of brain activity related to problem gambling may provide a deeper understanding of its underlying mechanisms, highlighting the importance of neurophysiological studies to better understand development and persistence of gambling behavior. The patterns of cognitive functioning have been investigated through electroencephalography (EEG) studies based on the near-win/near-miss (NW) effect. The main goal of the present study was to evaluate the neurophysiological basis of NWs and their modulation by gambling problems through a systematic review of event-related potentials (ERP) studies elicited by feedback events. The review followed the recommendations of the Preferred Reporting Items for Systematic Reviews and Meta-Analysis Protocols (PRISMA). A total of 15 studies were included, 12 comprising non-problem gamblers (NPGs) and three comparing problem gamblers (PGs) with matched controls. For the P300 component, the win outcome elicited a larger amplitude than the other outcomes (NW and loss), followed by the NW outcome, which elicited a larger amplitude than loss in some studies. For feedback-related negativity (FRN), the loss outcome evoked a more negative amplitude in several studies, despite eliciting a similar amplitude to NW outcomes in others. For PGs, the NW outcome evoked a higher amplitude of P300 than loss, while NPGs showed a similar amplitude to both outcomes. The present review gathered information from different sources and provides a consistent view of the different studies. However, studies lack systematic and robust methodologies, leading to inconsistent results and making it difficult to reach any definitive conclusions.

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
A large body of previous research has provided support for the role of attentional bias as a maintaining factor in addiction. This systematic review aimed to investigate the extent and nature of attentional bias as a phenomenon which exists within problem gamblers. Studies were identified through searches of three databases (MedLine, PSYCHINFO, and Web of Science) and examination of the reference lists of the final studies meeting criteria for inclusion. The scope of the review included empirical studies making experimental comparisons of problem gamblers and non-problem gamblers across a range of attentional paradigms. A comparison of effect sizes was conducted across studies comparing problem to non-problem gamblers within and between attention paradigms. Twenty-two studies were reviewed systematically across ten experimental paradigms. Attentional bias was demonstrated in 16 of the 22 studies, with attentional bias effects varying across paradigms. Quality assessment revealed two main limitations across studies: lack of a priori power analysis, and failure to control for gambling frequency as a possible confounding variable. Findings support the role of attentional bias as a potential maintaining factor in problem gambling behaviour, in line with evidence for substance addiction. Recommendations for future studies are outlined alongside a discussion of clinical implications.

Abstract
Gambling disorder is associated with deficits in reward-based learning, but the underlying computational mechanisms are still poorly understood. Here, we examined this issue using a stationary reinforcement learning task in combination with computational modeling and functional resonance imaging (fMRI) in individuals that regular participate in gambling (n = 23, seven fulfilled one to three DSM 5 criteria for gambling disorder, sixteen fulfilled four or more) and matched controls (n = 23). As predicted, the gambling group exhibited substantially reduced accuracy, whereas overall response times (RTs) were not reliably different between groups. We then used comprehensive modeling using reinforcement learning drift diffusion models (RLDDMs) in combination with hierarchical Bayesian parameter estimation to shed light on the computational underpinnings of this performance deficit. In both groups, an RLDDM in which both non-decision time and decision threshold (boundary separation) changed over the course of the experiment accounted for the data best. The model showed good parameter and model recovery, and posterior predictive checks revealed that, in both groups, the model accurately reproduced the evolution of accuracies and RTs over time. Modeling revealed that, compared to controls, the learning impairment in the gambling group was linked to a more rapid reduction in decision thresholds over time, and a reduced impact of value-differences on the drift rate. The gambling group also showed shorter non-decision times. FMRI analyses replicated effects of prediction error coding in the ventral striatum and value coding in the ventro-medial prefrontal cortex, but there was no credible evidence for group differences in these effects. Taken together, our findings show that reinforcement learning impairments in disordered gambling are linked to both maladaptive decision threshold adjustments and a reduced consideration of option values in the choice process.

Wolkowicz NR, Augur IF, Ham LS. The influence of negative urgency and mood inductions on alcohol cognitions. ALCOHOL, CLINICAL & EXPERIMENTAL RESEARCH 2024; 48:530-544.

Abstract
BACKGROUND Negative urgency (NU), the tendency to act rashly during negative emotional states, is a robust risk factor for alcohol misuse that is posited to function in part through alcohol-related cognitions. Nonetheless, relatively little research has examined mood-based fluctuations in such cognitions, which could help to explain how the trait of NU translates to impulsive alcohol-related behaviors. We examined how NU impacted several alcohol cognitions (positive/negative alcohol expectancies, positive/negative alcohol valuations, and alcohol craving for positive/negative emotional reinforcement) before and after negative, neutral, or positive mood inductions. We hypothesized that NU would predict greater and more favorable endorsement of alcohol and its effects following negative (vs. positive or neutral) mood induction. METHODS Participants (N = 428) were southern-midwestern college students recruited for an online experiment. Following the provision of consent, participants rated NU and preinduction alcohol cognitions, and were then randomly assigned to one of three (negative, neutral, or positive) mood inductions; subsequently, postinduction alcohol-cognition ratings were immediately obtained. We conducted six robust multilevel linear models (one per DV) examining NU's influence on within-person changes in alcohol cognitions across each mood induction. RESULTS No three-way interactions were identified and only one two-way interaction involving NU was identified. There were main effects across mood induction conditions and time points for NU predicting greater endorsement of positive and negative alcohol outcome expectancies, and greater alcohol craving for positive and negative emotional reinforcement. CONCLUSIONS Greater NU predicts greater perceived likelihood of alcohol's effects, alongside greater desire for mood improvement from alcohol. The absence of three-way interactive effects indicates NU's influence on mood-dependent fluctuations in alcohol cognitions may manifest over longer timescales (e.g., months and years), involve alternative cognitive processes (e.g., drinking motives and implicit alcohol cognitions), and apply more broadly to desires for mood improvement than purely negative emotional reinforcement.

Abstract
INTRODUCTION Pornography use is a common sexual activity with potentially addictive use in some people. Even though craving is being recognized as an important characteristic of addictive behaviors, there is a lack of a specific validated instrument measuring the pornography craving experience. The present study aimed at adapting and validating an instrument measuring the users' strength of pornography craving experience (PCE-S) based on the Elaborated Intrusion theory of desire. METHODS Items from the "strength" form of the Craving Experience Questionnaire (CEQ) were adapted to pornography use and used to create the PCE-S. The PCE-S was then administered online to 1584 English-speaking cyberporn users aged 18-75 years old (M = 33.18; SD = 10.84]; 63.1 % male, 35.2 % female, and 1.7 % non-binary). All participants completed an assessment of compulsive cyberporn use (CIUS adapted for cyberporn). Confirmatory factorial analysis (CFA) was used to examine the construct structure validity; Cronbach alpha coefficient, corrected item-total correlation, regression, and discriminant analysis were used to assess the instrument's psychometric properties. RESULTS After using the modification indices to improve the initial model, a relatively good fit for the three-factor model was confirmed. Concurrent validity with the compulsive cyberporn use (CCU) measure was demonstrated. The PCE-S discriminated between participants with high CCU and those with low CCU scores. CONCLUSIONS A specific pornography craving experience instrument scale, based on the Elaborated Intrusion theory of desire seems to capture key constructs of the theory and correlate with measures of compulsive cyberporn use.

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.
