RESUMO
"Technoference" describes the distraction from interpersonal activities that can occur due to use of mobile screen devices. Focusing on parent-infant interactions, our study investigated the associations between potential sources of "technoference" and parental responsiveness, scaffolding and directiveness toward their infant, and coordinated joint attention (CJA). Previous research demonstrates that each of these dimensions is related to early language development. Potential sources of "technoference" employed in our study included the amount of time the parent spends on their mobile device per hour when with their infant; the number of audible notifications the parent receives per hour, the number of times per hour they check their device; and parents' score on the Distraction In Social Relations and Use of Parent Technology (DISRUPT) scale. We investigated associations between our measures of parental "technoference" and infants' language development, and whether parental responsiveness, scaffolding, directiveness or parent-infant CJA mediate associations between "technoference" and language. Frequency of audible notifications negatively predicted infant vocabulary, and this relationship was fully mediated by parental directiveness.
