My research focuses on the intersection between mobile technology, parenting, parent-child interaction, and child development of processes such as executive functioning, self-regulation, and social-emotional well-being. Our projects use a combination of methods including surveys, videotaped parent-child interaction tasks, time diaries, and mobile device app logging to examine how parents and young children use mobile technologies throughout their day. We have developed novel content analysis approaches to understand the experience of young children while using commercially available mobile apps – including advertising content, educational quality, and data collection. We emphasize questions that are relevant to everyday parenting experiences, and also consider what design changes would help create an optimal default environment for children and families.
