AbstractYoung children exhibit a video deficit for spatial recall, learning less from on‐screen than in‐person demonstrations. Some theoretical accounts emphasize memory constraints (e.g., insufficient retrieval cues, competition between memory representations). Such accounts imply memory representations are graded, yet video deficit studies measuring spatial recall operationalize memory retrieval as dichotomous (success or failure). The current study tested a graded‐representation account using a spatial recall task with a continuous search space (i.e., sandbox) rather than discrete locations. With this more sensitive task, a protracted video deficit for spatial recall was found in children 4–5 years old (n = 51). This may be due to weaker memory representations in the screen condition, evidenced by higher variability and greater perseverative bias. In general, perseverative bias decreased with repeated trials. The discussion considers how the results support a graded‐representation account, potentially explaining why children might exhibit a video deficit in some tasks but not others.Research Highlights
The task used a continuous search space (sandbox), making it more difficult and sensitive than spatial recall tasks used in prior video deficit research.
Spatial recall among 4‐ and 5‐year‐old children was more variable after watching hiding events on screen via live video feed than through a window.
Children's spatial recall from screens was more susceptible to proactive interference, evidenced by more perseverative bias in an A‐not‐B design.
The results demonstrate memory representations blend experiences that accumulate over time and explain why the video deficit may be protracted for more difficult tasks.

Screen time, defined as estimates of child time spent with digital media, is considered harmful to very young children. At the same time, the use of digital media by children under five years of age has increased dramatically, and with the advent of mobile and streaming media can occur anywhere and at any time. Digital media has become an integral part of family life. Imprecise global screen time estimates do not capture multiple factors that shape family media ecology. In this Element, the authors discuss the need to shift the lens from screen time measures to measures of family media ecology, describe the new Dynamic, Relational, Ecological Approach to Media Effects Research (DREAMER) framework, and more comprehensive digital media assessments. The authors conclude this Element with a roadmap for future research using the DREAMER framework to better understand how digital media use is associated with child outcomes

Electronic media, particularly television, have long been criticized for their potential impact on children. One area for concern is how early media exposure influences cognitive development and academic achievement. Heather Kirkorian, Ellen Wartella, and Daniel Anderson summarize the relevant research and provide suggestions for maximizing the positive effects of media and minimizing the negative effects. One focus of the authors is the seemingly unique effect of television on children under age two. Although research clearly demonstrates that well-designed, age-appropriate, educational television can be beneficial to children of preschool age, studies on infants and toddlers suggest that these young children may better understand and learn from real-life experiences than they do from video. Moreover, some research suggests that exposure to television during the first few years of life may be associated with poorer cognitive development. With respect to children over two, the authors emphasize the importance of content in mediating the effect of television on cognitive skills and academic achievement. Early exposure to age-appropriate programs designed around an educational curriculum is associated with cognitive and academic enhancement, whereas exposure to pure entertainment, and violent content in particular, is associated with poorer cognitive development and lower academic achievement. The authors point out that producers and parents can take steps to maximize the positive effects of media and minimize the negative effects. They note that research on children's television viewing can inform guidelines for producers of children's media to enhance learning. Parents can select well-designed, age-appropriate programs and view the programs with their children to maximize the positive effects of educational media. The authors' aim is to inform policymakers, educators, parents, and others who work with young children about the impact of media, particularly television, on preschool children, and what society can do to maximize the benefits and minimize the costs.
