Although we have long known that many different types of individuals play video games, the stereotypical “gamer” is often portrayed as a young male. Furthermore, research into questions such as violence and aggression, addiction or problematic play, and toxic gaming communities tends to frame gamers and gaming as anti-social. From a philanthropic p...

Statistics show that sleep has become a problematic health issue, with significant proportions of the population coping with insufficient sleep, having trouble falling asleep, or suffering from clinical sleep disturbances. One of the factors contributing to the sleep loss epidemic appears to be electronic media use. Increases in media uses go hand...

Media scholars remain highly invested in uncovering how media technology transforms our life and affects how we spend time. This idea is rooted in the time displacement hypothesis, which proposes that time spent on one activity leaves less time available for others. Displacement effects are common in media studies: Numerous reports have shown that...

Purpose of Review There has been an exponential increase in publications on the effects of electronic media use on sleep. One of the fundamental questions on this topic concerns the underlying mechanisms: how or why are electronic media affecting sleep? This article aims to refine the existing theoretical framework by considering the role of self-c...

This study expands knowledge on the effects of technology use on sleep by (1) focusing onsocial media use in an adult sample, (2) investigating the difference between overall andnighttime-specific social media use with regards to sleep, and (3) exploring a vulnerabilityperspective. For the latter, the moderating roles of gender, age, and habitual s...

Sleep experts have raised concern over the effects of electronic media use on sleep. To date, few studies have looked beyond the effects of duration and frequency of media exposure or examined the underlying mechanisms of this association. As procrastinatory media use has been related to lower well-being, we used data from two survey studies (N1= 8...

Shuteye latency (SEL) refers to the time spent performing activities in bed before attempting sleep. This study investigates (a) the prevalence, duration and predictors of SEL, (b) its association with insomnia symptoms (sleep onset latency [SOL], sleep quality and fatigue), and (c) the activities engaged in during SEL. A representative sample of 5...

Objective: Sleep insufficiency has been related to self-control failure: people fail to go to bed in time and end up sleep deprived. The role of state self-control in predicting bedtime and sleep duration has not yet been investigated. Based on an overlap between depleted self-control resources and fatigue, self-control depletion may foster earlier...

Shuteye latency (SEL) refers to the time spent performing activities in bed before attempting sleep. This study investigates (1) the prevalence, duration, and predictors of SEL, (2) its association with insomnia symptoms (sleep onset latency (SOL), sleep quality and fatigue), and (3) the activities engaged in during SEL. A representative sample of...

Study objectives: To investigate the prevalence of binge viewing, its association with sleep and examine arousal as an underlying mechanism of this association. Methods: Four hundred twenty-three adults (aged 18-25 years old, 61.9% female) completed an online survey assessing regular television viewing, binge viewing, sleep quality (Pittsburgh S...

This study argues that going to bed may not be synonymous with going to sleep and that this fragmentation of bedtime results in a two-step sleep displacement. We separated bedtime (i.e. going to bed) from shuteye time (i.e. attempting to go to sleep once in bed) and assessed the prevalence of electronic media use in both time slots. A convenience s...

There is ample evidence that media use displaces sleep, but little theory about the mechanism that explains this. We studied sleep displacement as a self-control issue: People postpone going to bed because they have trouble ending their media exposure. We therefore modeled television viewing (habitual viewing, deficient TV self-regulation, and view...

The average amount of sleep people of all ages get has declined sharply in the past fifty years. The detrimental health effects of sleep deprivation are well documented and substantial. Even though electronic media use often takes place in the hours before sleep, the extent to which media use may interact with sleep is understudied and not well und...

Background: The few studies that have investigated the relationship between mobile phone use and sleep have mainly been conducted among children and adolescents. In adults, very little is known about mobile phone usage in bed our after lights out. This cross-sectional study set out to examine the association between bedtime mobile phone use and sl...

Over the years, criminological research has identified a number of risk factors that contribute to the development of aggressive and delinquent behavior. Although studies have identified media violence in general and violent video gaming in particular as significant predictors of aggressive behavior, exposure to violent video games has been largely...

A sample of 844 adults, aged 18-94 years old, was queried about media habits and sleep behavior in face-to-face interviews with standardized questionnaires. A substantial proportion of this sample reported using books (39.8%), television (31.2%), music (26.0%), Internet (23.2%), and videogames (10.3%) as a sleep aid. The use of media as sleep aids...

Most literature on the relationship between video gaming and sleep disturbances has looked at children and adolescents. There is little research on such a relationship in adult samples. The aim of the current study was to investigate the association of video game volume with sleep quality in adults via face-to-face interviews using standardized que...
