Behavioral adaptation is required for the successful navigation of a constantly changing environment. Impairments in behavioral flexibility are commonly observed in psychiatric disorders including those of addiction. This study investigates two distinct facets of compulsivity, namely reversal learning and attentional set shifting, implicating orbitofrontal and lateral prefrontal regions respectively, across disorders of primary and secondary rewards. Obese subjects with and without binge eating disorder (BED), individuals with compulsive sexual behaviors (CSB), alcohol dependence (AD) and pathological video-gaming (VG) were tested with two computerized tasks: the probabilistic reversal task (trials to criterion and win-stay/lose-shift errors) and the intra/extra-dimensional set shift task (IED)...

Internet addiction (including online gaming) has been associated with depression. However, most prior research relating internet addiction symptomatology to depressive symptoms has been cross-sectional, conducted with children and adolescents, and only examined depressive symptoms as a broad construct. The purpose of the current study was to examine potential longitudinal associations between anhedonia (i.e., difficulty experiencing pleasure, a key facet of depression) and internet-related addictive behaviors in 503 at-risk emerging adults (former attendees of alternative high schools)...

Cognitive constructs provide conceptual frameworks for transpathological characterization and improved phenotyping of apparently disparate psychiatric groups. This dimensional approach can be applied to the examination of individuals with behavioral addictions, for example, towards gambling, video-games, the internet, food, and sex, allowing operationalization of core deficits. We use this approach to review constructs such as impulsivity, compulsivity, and attention regulation, which may be most relevant, applicable, and successful for the understanding and subsequent treatment of the addictions...

Over the last decade, research into "addictive technological behaviors" has substantially increased. Research has also demonstrated strong associations between addictive use of technology and comorbid psychiatric disorders. In the present study, 23,533 adults (mean age 35.8 years, ranging from 16 to 88 years) participated in an online cross-sectional survey examining whether demographic variables, symptoms of attention-deficit/hyperactivity disorder (ADHD), obsessive-compulsive disorder (OCD), anxiety, and depression could explain variance in addictive use (i...

REVIEW
Jarid Goodman, Mark G Packard
The view that anatomically distinct memory systems differentially contribute to the development of drug addiction and relapse has received extensive support. The present brief review revisits this hypothesis as it was originally proposed 20 years ago (1) and highlights several recent developments. Extensive research employing a variety of animal learning paradigms indicates that dissociable neural systems mediate distinct types of learning and memory. Each memory system potentially contributes unique components to the learned behavior supporting drug addiction and relapse...

BACKGROUND: Individuals who are chronic, compulsive video game players experience an elevated incidence of major depression. Excessive or problematic game play can interact with depression clinically, and may magnify impulsive behavior associated with video gaming. METHODS: Functional brain imaging was performed during a Wisconsin Card Sorting Test (WCST) task in 42 healthy control and 95 volunteers seeking treatment for compulsive video game playing, including 60 participants without major depression (pure internet gaming disorder, pure IGD) and 35 participants comorbid with major depression (IGD+MDD)...

BACKGROUND AND AIMS: Exercise dependence (EXD) is considered a behavioral addiction that is often associated with eating disorders. To date, only few studies examined the potential overlap between EXD and other addictive behaviors. Therefore, the present study aimed at investigating the relationship of EXD with pathological buying, pathological video gaming (offline and online), hypersexual behavior, and alcohol use disorder in a sample of clients of fitness centers. METHODS: The following questionnaires were answered by 128 individuals (age M = 26...

Although electronic technology currently plays an integral role for most youth, there are growing concerns of its excessive and compulsive use. This study documents patterns and impact of electronics use in individuals with autism spectrum disorder compared to typically developing peers. Participants included 172 parents of typically developing individuals and 139 parents of individuals with an autism spectrum disorder diagnosis, ranging in age from 6 to 21 years. Parents completed an online survey of demographics and the frequency, duration, and problematic patterns of electronics use in their youth and young adults...

Temporal prediction (TP) is needed to anticipate future events and is essential for survival. Our sense of time is modulated by emotional and interoceptive (corporal) states that are hypothesized to rely on a dopamine (DA)-modulated "internal clock" in the basal ganglia. However, the neurobiological substrates for TP in the human brain have not been identified. We tested the hypothesis that TP involves DA striato-cortical pathways, and that accurate responses are reinforcing in themselves and activate the nucleus accumbens (NAc)...

INTRODUCTION: Internet addiction disorder (IAD) is characterized by the problematic use of online video games, computer use, and mobile handheld devices. While not officially a clinical diagnosis according to the most recent version of the Diagnostic and Statistical Manual of Mental Disorders (DSM), individuals with IAD manifest severe emotional, social, and mental dysfunction in multiple areas of daily activities due to their problematic use of technology and the internet. METHOD: We report a 31year-old man who exhibited problematic use of Google Glass™...

BACKGROUND: Many explanatory models of obsessive-compulsive disorders (OCD) support the idea that compulsive behaviours are an attempt to avoid an aversive situation. There are few experimental studies carried out on the onset of repetitive behaviours. This study tries to create a repetitive checking behaviour as an analogue explaining similar OCD behaviours. METHOD: An inter-group design with 3 levels of aversion (minimal, progressive and maximum) in a visuo-spatial reasoning task was used...

BACKGROUND: Several unhealthy behaviors are associated with psychosocial health in adolescents. Previous studies have shown that different adolescent health behaviors cluster, and, in order to understand these associations, it is important to investigate the relations between individual behaviors and psychosocial problems. PURPOSE: This study addressed the research question "Are adolescent health behaviors associated with psychosocial problems, and to what extent do certain health behaviors confound the relations between other health behaviors and psychosocial problems in adolescents?" METHODS: Self-reported questionnaire data on a broad range of health behaviors and demographics were collected from 2,690 high school students in the Netherlands in September 2012...

PURPOSE: Recent studies increasingly show adolescent health-related behaviors to be interrelated, interacting synergistically and sharing several common determinants. Therefore, research increasingly focuses on studying interventions that target a range of health behaviors simultaneously. This report describes the results of a pilot study of a secondary school-based, health-promoting intervention that simultaneously targets a range of adolescent health behaviors via a whole-school approach...

BACKGROUND: The cue-related go/no-go switching task provides an experimental approach to study individual's flexibility in changing situations. Because Internet addiction disorder (IAD) belongs to the compulsive-impulsive spectrum of disorders, it should present cognitive bias and executive functioning deficit characteristics of some of these types of disorders. Until now, no studies have been reported on cognitive bias and executive function involving mental flexibility and response inhibition in IAD...

The study explores the reliability, validity, and measurement invariance of the Video game Addiction Test (VAT). Game-addiction problems are often linked to Internet enabled online games; the VAT has the unique benefit that it is theoretically and empirically linked to Internet addiction. The study used data (n=2,894) from a large-sample paper-and-pencil questionnaire study, conducted in 2009 on secondary schools in Netherlands. Thus, the main source of data was a large sample of schoolchildren (aged 13-16 years)...

REVIEW
Reef Karim, Priya Chaudhri
The legitimacy of nonsubstance addictions has received increased attention from clinicians, researchers and the general population as more and more individuals report symptoms consistent with impairment of impulse control. The clinical presentation of these disorders is varied, as compulsive activities may include: gambling, eating, sex, shopping, use of the Internet or videogames or even exercising, working or falling in love. As such, there is great controversy in diagnosing, treating or even naming these conditions, as many of these behaviors are daily rituals instrumental to our ultimate survival...
