Methods: A critical analysis of available literature was conducted, and a de- bate took place with peers through the Open Science Framework (https://osf.io/q2vva/wiki/ home/). Results: An expanding body of research has classified engagement in a wide range of common behaviors and leisure activities as behavioral addictions, resulting in pathologizing of non-clinically relevant behaviors. Some of the reviewed studies are characterized by a confirmatory bias (e.g., a priori conceptualization of excessive appetitive behaviors as addictive disorders, recycling of substance abuse/dependence criteria, failure to consider alternative etiological models). Conclusions: An operational definition of behavioral addiction together with a number of exclusion criteria is proposed, in order to avoid pathologizing common behaviors and provide a common ground for further research. KS-2 Gambling disorder: Personal vulnerabilities and product features LUKE CLARK Centre for Gambling Research at UBC, Department of Psychology, University of British Columbia, Vancouver, Canada; E-Mail: [email protected] Recent years have seen an emerging consensus that gambling disorder should be considered a behavioral addiction in DSM-5 and ICD-11. The relative roles of personal vulnerability and gambling products features in shaping the development of disordered gambling remains poorly understood. In terms of vulnerability, gambling disorder is associated with elevated impulsivity and altered reward processing, but case-control studies by themselves are un- able to arbitrate whether these effects are precursors or consequences of the disorder. To shed further light on vulnerability mechanisms, we have examined individuals with gambling disorder as well as their unaffected biological siblings, using functional MRI with a gambling-based unpredictable reward task. In terms of gambling product features, our research 1 ICBA2018 / April 23–25, 2018 / Cologne, Germany Unauthenticated | Downloaded 09/30/21 11:38 AM UTC Keynote presentations focuses on modern slot machines as a more harmful form of gambling. Modern slot machines contain an array of structural characteristics including near-misses, sensory feedback, and opportunities for illusory control, which amplify reward-related brain activity in controlled experiments. Together, these features may create a state of immersion that is also predictive of problem gambling symptoms. Identification of the critical structural features of EGMs, and their interaction with personal vulnerabilities, is a necessary foundation for ‘responsible gambling’ practices, and for estimating the risks posed by emerging gambling technologies. KS-3 Behavioral addictions: An overview of research directions and developments ZSOLT DEMETROVICS & MARA J. RICHMAN Institute of Psychology, ELTE Eötvös Loránd University, Budapest, Hungary; E-Mail: [email protected]; [email protected] Background and aims: Research on behavioral addictions, including gaming disorder, gambling disorder, hypersexuality, exercise addiction, compulsive buying, and other excessive behaviors has increased significantly in the past years. The aim of this presentation is to overview this development and to examine which areas are developing satisfactorily and which are the ones that might require more research efforts in the future. Methods: System- atic literature review on the different behavioral addictions has been followed by quantitative and qualitative analyses of the available studies. Results and conclusions: Results show that there is an increasing amount of research available on behavioral addictions, however, there are significant differences according to the development of the different areas. Quality of the studies is diverse, and in most cases, cross-sectional design and convenient sampling domi- nates the field. Measurement issues, psychometric studies, and the examination of psycho- logical characteristics are important focuses, while much less attention is paid to biomarkers, neurobiological processes, and genetics. Lack of studies on clinical samples is also an important characteristic of the field. KS-4 Gender difference in Internet gaming disorder GUANGHENG DONG Department of Psychology, Zhejiang Normal University, P. R. China; E-Mail: [email protected] Studies have shown that male game players are more likely to develop Internet gaming disorder (IGD) than females do, however, the gender-related neurocognitive differences that may contribute to the different results remain unknown. We explored this issue with a series ICBA2018 / April 23–25, 2018 / Cologne, Germany 2 Unauthenticated | Downloaded 09/30/21 11:38 AM UTC Keynote presentations of studies, including the vulnerabilities that may contribute to the transformation to IGD, the brain responses to gaming cues in ordinary and deprivation situations, functional connectiv- ity during gaming and deprivation in different groups and so on. All these findings deepened our understanding about the mechanism underlying IGD.
