Imbalanced functional link between executive control network and reward network explain the online-game seeking behaviors in Internet gaming disorder

Literatures have shown that Internet gaming disorder (IGD) subjects show impaired executive control and enhanced reward sensitivities than healthy controls. However, how these two networks jointly affect the valuation process and drive IGD subjects' online-game-seeking behaviors remains unknown. Thirty-five IGD and 36 healthy controls underwent a resting-states scan in the MRI scanner. Functional connectivity (FC) was examined within control and reward network seeds regions, respectively. Nucleus accumbens (NAcc) was selected as the node to find the interactions between these two networks. IGD subjects show decreased FC in the executive control network and increased FC in the reward network when comparing with the healthy controls. When examining the correlations between the NAcc and the executive control/reward networks, the link between the NAcc - executive control network is negatively related with the link between NAcc - reward network. The changes (decrease/increase) in IGD subjects' brain synchrony in control/reward networks suggest the inefficient/overly processing within neural circuitry underlying these processes. The inverse proportion between control network and reward network in IGD suggest that impairments in executive control lead to inefficient inhibition of enhanced cravings to excessive online game playing. This might shed light on the mechanistic understanding of IGD.

Inclure l’addiction à Internet dans le DSM-V : étude de cas de la biomédicalisation des cyberdépendances

Le domaine de recherche scientifique sur les cyberdépendances présente de multiples définitions de cette pathologie. À partir du matériel empirique issu des débats relatifs à la proposition d'inclure l'addiction à Internet dans le Manuel Diagnostique et Statistique des Troubles mentaux (DSM-V), ce mémoire vise à comprendre les processus sociaux bornant le développement de cette pathologie au regard de la théorie de la biomédicalisation. À cette fin, un premier travail sociohistorique retrace les voies de la biologisation progressive des pratiques sociales de communication en ligne amorcées dès 1980. Un second travail d'analyse de discours systématise ensuite le processus normatif se dégageant des controverses scientifiques liées à son inclusion dans le DSM-V. La recherche menée suggère une interprétation théorique de cet objet située à l'intersection de tendances sociales propres à la société d'information. Le projet d'inclusion révèle la volonté d'une régulation sociale effectuée à partir de la transformation technoscientifique du vivant selon des processus santéistes et néolibéraux. Il donne ainsi à penser les discours scientifiques sur l'addiction à Internet comme avant tout politiques et économiques.

Non-Substance-Related Disorders: Gambling disorder and internet addiction

Behavioral addictions are highly prevalent and have a major individual and societal impact. Moreover, given the availability and increase of potentially addictive activities in our societal development (e.g. internet, gaming, online pornography) an increase in these types of behavioral disorders is very likely. Gambling Disorders are best studied among the non-chemical addictions. However, effective treatment interventions need to be further developed, in particular for Internet Addiction. Most of the available evidence supports behavioral interventions as first line treatment. Specifically for Gambling Disorder, pharmacotherapy can be an useful augmentation.. Psychiatric comorbidities are frequent in patients with behavioral addictions and negatively affect the course of non-substance-related disorders. Concurrent treatment of these comorbid disorders is advised, although there is a clear need of conducting studies evaluating the effectiveness of integrated treatment approaches.

Le jeu en ligne : une analyse comparative du statut juridique du jeu en ligne et des cadres juridiques adoptés pour règlementer et gérer ses risques.

Le jeu a toujours été perçu comme un vice, responsable de nombreux troubles sociaux. Par conséquent, les gouvernements ont adopté divers cadres juridiques pour contrôler et gérer ses conséquences négatives. Malgré qu'il soit omniprésent, le jeu en ligne est illégal au Canada, aux États Unis et dans plusieurs autres pays. La règlementation du jeu en ligne et la gestion de ses troubles sociaux présente un plus grand défi pour les gouvernements, particulièrement en raison de sa nature technologique et extraterritoriale. Ce mémoire identifiera les risques et conséquences liés au jeu, en particulier les problèmes de jeu, ainsi que les cadres juridiques adoptés pour les règlementer et minimiser. Nous examinerons le statut juridique du jeu en ligne dans différentes juridictions, dont le Canada, les États Unis, le Royaume-Uni et ailleurs dans l'Union européenne. Ces cadres juridiques comprennent l'interdiction du jeu en ligne aux États Unis, la légalisation, l’octroi de licences et taxation du jeu en ligne au Royaume Uni et les cadres juridiques employés au Canada et ailleurs, offrant du jeu en ligne exclusivement par l’entremise de monopoles d'état pour contrôler sa disponibilité et minimiser ses conséquences néfastes. Nous tirerons des conclusions quant à l'efficacité relative des différents cadres juridiques adoptées pour règlementer le jeu en ligne.

Lightweight peer-to-peer secure multi-party VoIP protocol

Multi-party voice-over-IP (MVoIP) services provide economical and convenient group communication mechanisms for many emerging applications such as distance collaboration systems, on-line meetings and Internet gaming. In this paper, we present a light peer-to-peer (P2P) protocol to provide MVoIP services on small platforms like mobile phones and PDAs. Unlike other proposals, our solution is fully distributed and self-organizing without requiring specialized servers or IP multicast support.

It’s Not Just a Game: Contemporary Challenges for Games Research and the Internet

In this final chapter we will raise a number of issues that we have encountered as we have put this collection of papers together. In doing this, we also reflect upon the seven challenges for video game theory that Bernard Perron and Mark Wolf(2009)put forward in the introduction to the second video game theory reader given it is probably one of the most recent assessments in the area at the time of writing. These challenges are concerned with Terminology and Accuracy, History, Methodology, Technology, Interactivity, Play and the Integration of Interdisciplinary Approaches. These issues will be brought up throughout this chapter, but not necessarily in mutually exclusive fashion...

Online Gaming in Context : the Social and Cultural Significance of Online Games

There is little question of the social, cultural and economic importance of video games in the world today, with gaming now rivalling the movie and music sectors as a major leisure industry and pastime. The significance of video games within our everyday lives has certainly been increased and shaped by new technologies and gaming patterns, including the rise of home-based games consoles, advances in mobile telephone technology, the rise in more 'sociable' forms of gaming, and of course the advent of the Internet. This book explores the opportunities, challenges and patterns of gameplay and sociality afforded by the Internet and online gaming. Bringing together a series of original essays from both leading and emerging academics in the field of game studies, many of which employ new empirical work and innovative theoretical approaches to gaming, this book considers key issues crucial to our understanding of online gaming and associated social relations, including: patterns of play, legal and copyright issues, player production, identity construction, gamer communities, communication, patterns of social exclusion and inclusion around religion, gender and disability, and future directions in online gaming.

Mobile E-commerce business model – A value web based approach to business models in mobile gaming industry

Tämän tutkimuksen tavoitteena oli tutkia langattomien internet palveluiden arvoverkkoa ja liiketoimintamalleja. Tutkimus oli luonteeltaan kvalitatiivinen ja siinä käytettiin strategiana konstruktiivista case-tutkimusta. Esimerkkipalveluna oli Treasure Hunters matkapuhelinpeli. Tutkimus muodostui teoreettisesta ja empiirisestä osasta. Teoriaosassa liitettiin innovaatio, liiketoimintamallit ja arvoverkko käsitteellisesti toisiinsa, sekä luotiin perusta liiketoimintamallien kehittämiselle. Empiirisessä osassa keskityttiin ensin liiketoimintamallien luomiseen kehitettyjen innovaatioiden pohjalta. Lopuksi pyrittiin määrittämään arvoverkko palvelun toteuttamiseksi. Tutkimusmenetelminä käytettiin innovaatiosessiota, haastatteluja ja lomakekyselyä. Tulosten pohjalta muodostettiin useita liiketoimintakonsepteja sekä kuvaus arvoverkon perusmallista langattomille peleille. Loppupäätelmänä todettiin että langattomat palvelut vaativat toteutuakseen useista toimijoista koostuvan arvoverkon.

Preadolescents' internet usage : psychosocial implications /

Preadolescent Internet usage is prevalent today. This thesis examined how Canadian preadolescents use the Internet, what they do when they are on the Internet, and why preadolescents are fascinated with the Internet. Eight quahtative categories were derived from the data. The categories are Downloading, Information Hunting, Consumerism, Virtual Nurturing, Gaming, Expressions of Violence, Chatting, and Music. By critically distilling and analyzing preadolescent Internet behaviour through the lens of behavioural and cognitive psychology, and explicating the amount of psychological, cognitive, and social learning that preadolescents may be exposed to on the Internet, and the attraction that is cumulatively a profound draw for a preadolescent audience, an argument will be made that Internet usage in preadolescents may impair their cognitive, social, and psychological development because of the impulse seeking and gratification priming that has been reinforced during the formative period of preadolescence.
