* Abbreviation: EF — : executive function Theories regarding the impact of media on development can largely be grouped into content-based and content-independent categories.1 Content-based theories argue that the impact of media on aspects of development differs depending on content. For example, media that involve prosocial themes (eg, helping) may positively impact children’s behavior, whereas media that involve violence have the potential to negatively impact behavior. Content-independent theories argue that many of the impacts of media occur irrespective of the content children are exposed to. For example, irrespective of content, viewing media may displace other activities (eg, reading) that positively contribute to children’s intellectual development. A third theory that contains both content-based and content-independent elements is based on media form. Briefly, form-based theories argue that specific features of media may negatively impact children’s behavior. Although form-based theories are generally classified as content-independent,1 many forms commonly intersect with certain types of content. Concerns regarding form have largely focused on the pace of media (ie, the frequency of scene changes or cuts) and the impact pacing may have on aspects of executive function (EF). EF comprises a number of skills, including self-regulation, working memory, and problem solving. Empirical investigations of the potential link between pace and EF can be traced back … Address correspondence to Damian Scarf, PhD, Department of Psychology, University of Otago, PO Box 56, Dunedin 9054, New Zealand.
