Research: Longitudinal

Browse Research






Although there is a substantial body of research that has investigated the impact of media on older children, the effects of media use on very young children are not yet well established in the literature.  Furthermore, effects-based research infrequently employs longitudinal methodology, thus leaving the question of the media's impact on children's developmental trajectories largely unanswered.

The focus of our longitudinal research is to examine the patterns of media usage in infancy and early childhood, and the effects of these media on development (e.g., cognitive and language) and school readiness. By developing a healthy educational media diet for children and families, as well as providing parents with appropriate guidelines for using media in their homes, we hope to uncover the impact that quality educational media have on children's early development.

Longitudinal Study of Early Media Exposure and Subsequent School Readiness: April 2009 Update

Despite the American Academy of Pediatrics’ recommendation of no screen media for children under the age of two, 72% of parents believe that early exposure to computers was “mostly helpful” and 58% believed that early exposure to educational television programming was “very important” (Rideout et al., 2003).  Prior research has shown that quality educational screen media can be beneficial for children at least as young as two.  Moreover, we know that exposure to specific foreground television programs designed for infants can enhance their language development (Linebarger & Walker, 2005). Furthermore, children who are exposed to high-quality children's educational programs during the preschool years have enhanced cognitive development, language development, and prosocial skills, as well as a long-term positive impact on school readiness and academic performance (Anderson, Huston, Schmitt, Linebarger, & Wright, 2001).  Still, no longitudinal research has been conducted to assess the impact of infant exposure to television or to computer programs on subsequent school readiness.

Content Analysis of Educational Media Products for Infants, Toddlers and Preschoolers

Research Brief 18 prepared for Corporation for Public Broadcasting. Philadelphia, PA: Annenberg School for Communication, University of Pennsylvania.

The research available for infants and young children indicate that quality media can have benefits for even the youngest viewers, depending on structure, content and production features (Barr, Muentener, Garcia, Fujimoto, & Chavez, 2006; Krcmar, Grela & Lin, 2007; Linebarger & Walker, 2005; Richert, 2007). What is needed, then, are systematic analyses of the ways young children’s media products substantiate their educational claims by incorporating beneficial production techniques as well as more general learning strategies known to enhance children’s development. Thus, the focus of this content analysis is to determine the extent to which young children’s media products (television programs, DVDs and video-games) which claim educational or developmental benefits substantiate those claims through age-appropriate content and production characteristics theoretically and empirically shown to support children’s learning and development. Additionally, this analysis will be used to inform the intervention for an experimental longitudinal healthy media study. Moreover, the knowledge gained from these analyses will be utilized to construct healthy media intervention packages for a larger longitudinal experimental analysis of the contribution of quality media to child development and school readiness.

Reports

Language Promoting Strategies Embedded in Infants' Educational Videos

Vaala, S. & Linebarger, D.L. (2009). Language promoting strategies embedded in infants' educational videos. A final report prepared for the Corporation for Public Broadcasting. Philadelphia, PA: Annenberg School for Communication, University of Pennyslvania.

Over the past decade, the market for infant and toddler media products has increased tremendously. Baby videos are a common feature in American homes, and many parents of infants and toddlers use these products with the expectation that they will have some educational or developmental benefit for their child (Zimmerman, Christakis & Meltzoff, 2007). The average American 6-month-old infant has at least four DVDs/videos, including such titles as Baby Einstein, Brainy Baby and Baby Genius (Barr, Lally, Hilliard, Andolina & Ruskis, 2009). By 18 months of age, the number of DVDs/videos jumps to over seven on average. Recent surveys indicate that the typical child under three spends 95 minutes of an average day exposed to some form of screen media of which 61 minutes is in front of a TV screen (i.e., TV, DVDs/videos; Rideout & Hamel, 2006). To date, there is no published research systematically documenting the educational content present, or the types and relative quantities of language-promoting teaching strategies used in commercially available infant and toddler videos. The focus of this study was to systematically analyze the ways infant-directed programs incorporate content and strategies (e.g., labeling), known to aid young children’s language development. We were curious about the extent of language-related developmental claims made by producers of infant and toddler programming, and hypothesized that these claims would be accompanied by a greater amount of language-related general content and specific language-promoting strategies.
