Mobile Media Content Exposure and Toddlers’ Responses to Attention Prompts and Behavioral Requests

Abstract

ImportanceWith personalized touch-screen tablets, young children can choose content and engage in play-like activities. However, tablets may also reduce shared engagement as the action of viewing or touching the screen is often not visible to nearby adults. This may impact communicative gazing and pointing, which is critical to the formation of shared awareness and in turn supports language development.ObjectiveTo assess the association of tablet media content with toddlers’ responses to joint attention prompts and behavioral requests.Design, Setting, and ParticipantsThis cohort study took place at a behavioral research laboratory and included toddlers who were aged 18 to 32 months with neurotypical development who were recruited from a volunteer and community sample. Toddlers engaged with a real toy or 3 different types of tablet content (ie, viewing video of toy play, playing with a digital toy, or playing a commercial game) while an experimenter delivered joint attention prompts. Data were acquired from June 2021 November XX 2022, and data analysis occurred from January 2023 to May 2024.Main Outcomes and MeasuresMain outcomes included child response to joint attention (number of prompts with joint attention response per number of prompts delivered) and child response to behavioral request (ie, the prompt on which the child responded to the behavioral request). Measures included crossed random effects, Wald tests, and likelihood ratio tests.ResultsIn this study, 63 toddlers were enrolled, and data from 62 were included (31 female [49%]; mean [SD] age, 26.1 [3.4] months; median [IQR] age, 25.0 [18.6-32.6] months). When toddlers were playing a commercial game on a tablet, they responded to fewer joint attention prompts (crossed random effects model, −0.15; 95% CI, −0.24 to −0.06 prompts) and male toddlers took longer to acknowledge a behavioral request (interaction of content and sex, −0.75; 95% CI, −1.36 to −0.17). The negative impact of the tablet game was larger as child age increased (τ = −2.30; 95% CI, −0.05 to 0; P = .03). Greater media use at home was associated with decreased responding to joint attention prompts during the tablet game (ρ = −0.47; P < .001), while better language skills were associated with more joint attention during play with a real toy (ρ = 0.31; P = .02).Conclusions and RelevanceIn this cohort study, a touch-screen tablet game was associated with decreased joint attention among toddlers and they were less likely to respond to a behavioral request. In a laboratory setting, it was difficult for toddlers to engage in social-communicative interactions with adults when using a tablet media device.
