Studies examining the effects of exposure to prosocial media on positive outcomes are increasing in number and strength. However, existing meta-analyses use a broad definition of prosocial media that does not recognize the multidimensionality of prosocial behavior. The aim of the current study is to conduct a meta-analysis on the effects of…

Sociocultural theory of body dissatisfaction posits that internalization of the media ideal and appearance comparison are predictors of body dissatisfaction, a key risk factor for eating disorders. However, no data exist regarding the longitudinal relationships between these variables. The aim of this study was to explore longitudinal…

Media exposure among young children has been suggested to influence self-concept and the adoption of social stereotypes regarding body weight, as well as being associated with increased weight. The aim of this study was to examine the role of TV/DVD viewing in the development of positive stereotypes toward thinness, self-esteem and body mass index…

Three studies examined the short-term impact of television (TV) on children's executive function (EF). Study 1 (N = 160) showed that 4- and 6-year-olds' EF is impaired after watching 2 different fast and fantastical shows, relative to that of children who watched a slow, realistic show or played. In Study 2 (N = 60), 4-year-olds' EF was as…

To make a scientific contribution, a reanalysis must be firmly rooted in the identification of a clearly superior methodological innovation over the original research. By contrast, a reanalysis rooted in dissatisfaction with previous results will necessarily be biased and can only obscure scientific discoveries. The reanalysis published by…

An approach-avoidance model of social withdrawal (Asendorpf, 1990) identifies 3 types of social withdrawal including shyness, unsociability, and avoidance. Each appears to be uniquely associated with varying indicators of maladjustment in emerging adulthood (Nelson, 2013) but little, if any, work has been done to see how they might be linked to…

The current study examined longitudinal cross-lagged associations between prosocial TV (content and time) and prosocial and aggressive behavior during adolescence, and explored the mediating role of empathic concern and self-regulation. Participants were 441 adolescents who reported on their 3 favorite TV shows at 2 time points, approximately 2…

This study investigated the relations between television exposure during the preschool years and the development of executive function (EF). Data were gathered from 107 parents of preschoolers who provided information on children's television viewing, background television exposure, exposure to specific televised content, and the age at which…

Mass media have numerous effects on children, ranging from influencing school performance to increased or reduced aggression. What we do not know, however, is how media availability in the bedroom moderates these effects. Although several researchers have suggested that bedroom media may influence outcomes by displacing other activities (the…

There are several theoretical reasons to believe that media use might be related to attention-deficit/hyperactivity disorder (ADHD) or ADHD-related behaviors (i.e., attention problems, hyperactivity, and impulsivity). Although studies into the media--ADHD relationship have accumulated, they have yielded inconsistent results. Therefore, we still do…

Adolescence is an important developmental stage during which both peers and the media have a strong influence. Both peer rejection and the use of morally adverse media are associated with negative developmental outcomes. This study examines processes by which peer rejection might drive adolescents to select antisocial media content by tying…

Longitudinal research has demonstrated a link between exposure to sexual content in media and subsequent changes in adolescent sexual behavior, including initiation of intercourse and various noncoital sexual activities. Based on a reanalysis of one of the data sets involved, Steinberg and Monahan (2011) have challenged these findings. However,…

Zimmerman, Christakis, and Meltzoff (2007) reported that exposure to Baby Einstein videos was negatively associated with language development. The current study uses the Zimmerman et al. (2007) data set to replicate and extend the original analyses. Caregivers of 392 children aged 6 to 16 months and 358 children aged 17 to 27 months reported on…

It is widely believed that exposure to sexy content in the mass media leads teenagers to become sexually active. Although most research linking sexy media exposure to adolescents' sexual behavior is cross-sectional, several recent, well-publicized longitudinal studies purport to find a causal connection, which has alarmed the public and prompted…

The developmental trajectory of body image dissatisfaction is unclear. Researchers have investigated sociocultural and developmental risk factors; however, the literature needs an integrative etiological model. In 2009, Cheng and Mallinckrodt proposed a dual mediation model, positing that poor-quality parental bonds, via the mechanisms of…
