Rationale Visuo-perceptive deficits in severe alcohol use disorder (SAUD) remain little understood, notably regarding the respective involvement of the two main human visual streams, i.e., magnocellular (MC) and parvocellular (PC) pathways, in these deficits. Besides, in healthy populations, low-level visual perception can adapt depending on the na...
Article
Background: Perfectionistic individuals present exaggerated performance standards, generating a constant search for flawlessness and a high tendency to self-criticize. Dominant models distinguish three dimensions of perfectionism, namely self-oriented, socially-prescribed and other-oriented. Perfectionism constitutes a vulnerability factor for psyc...
Article
Full-text available
In severe alcohol use disorder (SAUD), attentional bias refers to the preferential allocation of attentional resources toward alcohol-related cues. Dominant models consider that this bias plays a key role in the emergence and maintenance of SAUD. We evaluate the available experimental support for this assumption through a systematic literature revi...
Article
Introduction: The exploration of cognitive impairments associated with tobacco use disorder has expanded during the last decades, centrally showing working memory and executive deficits among smokers. Despite their critical role in everyday life and in the smoking cessation process, attentional abilities have seldom been explored. Previous studies...

Brain imaging studies have shown that stimulation of the left dorsolateral prefrontal cortex (dlPFC), which plays a pivotal role in high-order cognitive control processes, modulates brain reactivity to reward-related cues. Nevertheless, the impact of contextual factors such as reward availability (the reward that is depicted in the cue exposure tas...
Article
Full-text available
This research examines the relationship between metadehumanization – that is, perceiving dehumanizing treatments – and self-dehumanization – that is, perceiving oneself as less than human. We argue that, in work settings, this relationship can be explained through a behavioral mechanism. Specifically, organizational metadehumanization would drive e...

This commentary challenges some of the proposals made in the opinion paper entitled “The expanded interactional model of exercise addiction” by Dinardi, Egorov, and Szabo (2021). We first question the usefulness of the (expanded) interactional model of exercise addiction to determine the psychological processes underlying distress and functional im...
Article
Visuospatial impairments have long been reported in Severe Alcohol Use Disorder but remain poorly understood, notably regarding the involvement of magnocellular (MC) and parvocellular (PC) pathways. This empirical gap hampers understanding the implications of these visual changes, especially since the MC and PC pathways are thought to sustain centr...
Article
Background: Numerous risk factors have been involved in the pathogenesis of hypertension. The contribution of psychological factors, including post-traumatic stress disorder, remains largely underexplored, despite their potential role in hypertension. Objectives: We compared the prevalence of trauma, post-traumatic stress and other psychological...
Article
Full-text available
The present literature review aimed at offering a comprehensive and critical view of the behavioral data collected during the past seventy years concerning visuoperception in severe alcohol use disorders (SAUD). To pave the way for a renewal of research and clinical approaches in this very little understood field, this paper: (1) provides a critica...
Article
Background: Consistent data highlight the presence and clinical significance of social cognition impairments in severe alcohol use disorder (SAUD). However, important social cognition components, notably social perception and knowledge (i.e. the ability to identify and interpret latent social rules from social situations), have not yet been explore...
Article
Background Patients with severe alcohol use disorder (SAUD) demonstrate multifaceted impairments in social cognition abilities like emotional decoding or Theory of Mind. Such impairments are related to real-life interpersonal difficulties, which in turn might be involved in the persistence of SAUD. However, far less is known regarding how patients...
Article
Introduction: The coronavirus disease 2019 (COVID-19) outbreak and the related lockdown measures have raised concerns regarding mental health, including alcohol misuse. Preliminary studies investigated alcohol consumption at the early stages of lockdown, but no longitudinal data regarding its evolution during and after the first lockdown are curren...
Article
Full-text available
Metadehumanization, the perception of being treated as less than a human by others, is a pervasive phenomenon in intergroup relations. It is dissociated from stigmatization or stereotypes, and it has been recently identified as a critical process in severe alcohol use disorders (SAUD). Metadehumanization is associated with a wide array of negative...
Article
Interoception, defined as the ability to perceive and interpret body signals, may play an important role in alcohol use disorder (AUD). Earlier studies suggested an association between interoception impairment and known risk factors for AUD (e.g., alexithymia, emotion dysregulation, impulsivity, pain). Neurobiological studies show that the neurotox...
Article
Full-text available
Aims Negative and Positive urgency are emotion-related impulsivity traits that are thought to be transdiagnostic factors in psychopathology. However, it has recently been claimed that these two traits are closely related to each other and that considering them separately might have limited conceptual and methodological value. The present study aime...
Article
Full-text available
Rationale: Attitudes towards alcohol constitute a central factor to predict future consumption. Previous studies showed that young adults with risky alcohol consumption present positive implicit and explicit attitudes towards alcohol. Objectives: It appears crucial to disentangle the relationship between specific consumption patterns (e.g., binge...

The preservation of our environment requires sustainable ways of thinking and living. This study aimed to explore the core network of brain regions involved in the prospective thinking about (un)sustainable behaviors. We used a neuroimaging cue-exposure paradigm requesting participants (N=86) to report behaviors that were the most feasible for them...
Article
Background: Dominant theoretical models consider that attentional biases (AB) towards alcohol-related stimuli play a key role in the development and maintenance of alcohol use disorder (AUD). Their assessment has however showed high inconsistencies and has been mostly based on unreliable behavioral measures. This study evaluated the presence and ex...
Article
Attentional, executive, and memory processes play a pivotal role in time perception. As acute or chronic alcohol consumption influences these processes, it should also modify time perception. We systematically reviewed and critically assessed all existing studies on time perception among alcohol drinkers, following the PICOS procedure and PRISMA gu...
Article
Background: Metadehumanization (i.e., the perception of being considered as less than human by others) is proposed to be widespread in stigmatized populations, such as people with severe alcohol use disorder (SAUD). However, the relations between metadehumanization, self-dehumanization (i.e., the self-perception of being less than human), and stigm...
Article
An online survey among French-speaking Belgians (N=7711) investigated self-reported changes in alcohol consumption during the first COVID-19-related lockdown (March 17th – May 4th 2020). Population-weighted estimates indicated that 31.37% of the population increased consumption during lockdown, 30.32% decreased consumption and 38.31% reported uncha...
Article
Background: People with mental illness are stigmatized and dehumanized, which contributes to disorders’ maintenance. Dehumanization is associated with abuse/neglect and should thus be evaluated among healthcare workers. We compared nurses' stigmatizing/dehumanizing perceptions of people with psychiatric versus non-psychiatric disorders. We also inv...

Full-text available
Despite the frequency of women's exposure to sexually objectifying behaviors in their daily life, (e.g., through comments on their appearance, gazing or touching), no previous work has investigated how such a focus on their physical appearance influences women’s meta-perceptions. Capitalizing on recent studies showing that sexually objectified wome...
Article
Full-text available
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...
Article
We investigated changes in alcohol consumption following the COVID-19 lockdown among French-speaking Belgian individuals at risk for severe alcohol use disorder. Participants (N=299) at risk for alcohol use disorder (AUD, i.e., score higher than 19 at the Alcohol Use Disorder Identification Test), and 299 moderate drinkers (MOD, i.e., score lower t...
Article
Background: Severe Alcohol Use Disorder (SAUD) is associated with widespread cognitive impairments, including low-level visual processing deficits persisting even after prolonged abstinence. However, the extent and characteristics of these visual deficits remain largely undetermined, impeding the identification of their underlying mechanisms and i...
Article
Background and rationale: Severe alcohol use disorder (SAUD) is a major public health concern, given its massive individual, interpersonal and societal consequences. The available prevention and treatment programs have proven limited effectiveness, as relapse rates are still high in this clinical population. Developing effective interventions reduc...
Article
The unprecedented development and ubiquity of sports betting constitutes an emerging public health concern. It is crucial to provide markers that could help to better identify people experiencing sports betting-related harms. The current study investigated whether problem gambling status, sports betting passion, and trait self-control modulate brai...
Article
This study aimed to delineate the specific characteristics of binge drinking habits by capitalizing on data-driven network analysis. Such an approach allowed us to consider binge drinking as a network system of interacting elements, thus identifying the key variables involved in this phenomenon. A total of 1,455 university students with excessive d...

Article
Background: Severe alcohol use disorder (SAUD) is associated with social cognition deficits. Patients with SAUD are impaired for the recognition of emotional facial expressions, particularly at early stages of abstinence. These deficits damage interpersonal relations and increase relapse risk. However, uncertainties still abound on their variation...
Article
This research examined the negative relationship between leader-member exchange (LMX) and organizational dehumanization (i.e., employees’ perceptions that their organization treats them like tools), and specifically the consequences of this LMX-dehumanization relationship on employees’ emotional exhaustion, affective commitment, and voice behaviors...
Article
Binge drinking is a widespread alcohol consumption pattern commonly engaged by youth. Here, we present the first systematic review focusing on emotional processes related to binge drinking. Capitalizing on a theoretical model describing three emotional processing steps (emotional appraisal/identification, emotional response, emotional regulation) a...
Article
We investigated how two forms of objectification (i.e., sex- and beauty-based objectification) relate to metadehumanization (i.e., the perception of being dehumanized) and emotional consequences for victims. Capitalizing on previous research, we hypothesized that sex-based objectification would induce animalistic metadehumanization and that beauty-...
Article
Visuoperceptive deficits are frequently reported in severe alcohol use disorder (SAUD) and are considered as pervasive and persistent in time. While this topic of investigation has previously driven researchers’ interest, far fewer studies have focused on visuoperception since the ‘90s, leaving open central questions regarding the origin and implic...
Article
Rationale: Severe alcohol use disorder (SAUD) is a psychiatric condition linked to cerebral and cognitive consequences. SAUD is notably characterized by an over-activation of the reflexive/reward system when confronted with alcohol-related cues. Such over-reactivity generates a preferential allocation of attentional resources towards these cues, la...
Chapter
While severe alcohol use disorder (SAUD) is classically characterized as a compulsion to seek and consume alcohol and a reduced ability to control these behaviors, a growing number of studies shows social cognition difficulties among recently detoxified patients. The present chapter proposes an overview of this literature by presenting the main fin...
Article
The global outbreak of coronavirus disease 2019 (COVID-19) and the resulting lockdown measures have raised concerns regarding their effect on alcohol consumption. We investigated alcohol use during lockdown in a population of college students, usually characterized by social and heavy drinking. We also tested the predictive role of pre-lockdown dri...
Article
Alcohol use disorder (AUD) has been associated with impairments in social and emotional cognition that play a crucial role in the development and maintenance of addiction. Repeated alcohol intoxications trigger inflammatory processes and sensitize the immune system. In addition, emerging data points to perturbations in the gut microbiome as a key r...

This research field has recently benefited from the emergence of innovative measures, among which eye track...
Article
Background: Attentional bias towards alcohol-related stimuli is a core characteristic of severe alcohol use disorders (AUD), directly linked to clinical variables (alcohol consumption, relapse). Nevertheless, the extent of this bias in subclinical populations remains poorly documented. This is particularly true for binge drinking, an alcohol consum...
Article
Severe alcohol use disorders (SAUD) are associated with a large variety of affective disturbances, among which a well-established decoding deficit for facial and vocal emotional expressions. This deficit has recently been found to be increased in cross-modal settings, namely when inputs from different sensory modalities have to be combined. Compare...
Article
Full-text available
Interoceptive accuracy is frequently assessed using the Heartbeat Counting Task (HCT), requiring participants to count the number of times their heart beats. The HCT validity has been questioned, as participants may perform the task by estimating, rather than counting, their felt heartbeats. Participants could estimate the time or use their knowled...

Full-text available
Substance use in youth is a central public health concern, related to deleterious consequences at psychological, social, and cognitive/cerebral levels. Previous research has identified impulsivity and consumption motives as key factors in the emergence of excessive substance use among college students. However, most studies have focused on a specif...
Article
Background: Severe alcohol use disorder (SAUD) is associated with impaired discrimination of emotional expressions. This deficit appears increased in crossmodal settings, when simultaneous inputs from different sensory modalities are presented. However, so far, studies exploring emotional crossmodal processing in SAUD relied on static faces and unm...
Article
Full-text available
Rationale. Binge drinking (i.e., excessive episodic alcohol consumption) among young adults has been associated with deleterious consequences, notably at the cognitive and brain levels. These behavioural impairments and brain alterations have a direct impact on psychological and interpersonal functioning, but they might also be involved in the tran...

Full-text available
In view of the growing interest regarding binge-watching (i.e., watching multiple episodes of television (TV) series in a single sitting) research, two measures were developed and validated to assess binge-watching involvement (“Binge-Watching Engagement and Symptoms Questionnaire”, BWESQ) and related motivations (“Watching TV Series Motives Questi...
Article
Full-text available
Rationale: Binge drinking (BD), characterized by recurring alternations between intense intoxication episodes and abstinence periods, is the most frequent alcohol consumption pattern in youth and is growing in prevalence among older adults. Many studies have underlined the specific harmful impact of this habit by showing impaired abilities in a wid...
Article
In the present paper, we investigate dehumanization processes from a victim perspective. We propose that dehumanization experiences, i.e. metadehumanization, arise from people’s feelings that their fundamental human needs are thwarted and that such experiences influence their emotions, self-esteem, and coping strategies. Our model is put at test in...
Article
Full-text available
Binge-watching (i.e., watching multiple episodes of TV series back-to-back) has become standard viewing practice. Yet, this phenomenon has recently generated concerns regarding its potential negative outcomes on the long run. The presumed addictive nature of this behavior has also received increasing scientific interest, with preliminary findings r...
Article
Background: Dehumanization, i.e., the denial of one’s humanity, has important consequences for social interactions. Earlier works mainly studied the dehumanizer’s perspective, neglecting victims and particularly psychiatric populations. This study’s goal is thus to investigate if patients with severe alcohol-use disorders (SAUD) feel dehumanized by...
Article
Deficits in social perception and knowledge and their negative impact on social functioning, have been repeatedly reported among patients with schizophrenia. However, earlier studies have focused on an overall assessment of social perception and social knowledge, without exploring their sub-components nor the interindividual variation of the defici...
Article
Numerous studies have explored the morphological differences of the brain between subjects with alcohol use disorder (AUD) and control subjects, but very few have investigated the impact of the duration of alcohol use disorder (DAD) and current level of alcohol consumption (CAC) within AUD subjects using magnetic resonance imaging (MRI). We compare...
Article
Full-text available
Previous literature has consistently reported socio-affective information processing impairments in patients with severe alcohol-use disorder (SAUD). Some recent studies have also suggested that these patients might exhibit biases toward stimuli indicating social threat, such as angry or disgusted faces. Such biases have been largely documented in...
