Who Leads and Who Follows? The Pathways to Joint Attention During Free-Flowing Interactions Change Over Developmental Time.

Joint attention (JA) has been found to correlate with many developmental outcomes. However, little is known about how naturalistic JA is established and develops during early infancy. In this study, free-flowing tabletop toy play between infants at 5 and 15 months and their mothers (N = 48 dyads; 65% white) was observed to (1) examine changes in JA, (2) investigate whether infants become better leaders or followers of JA, and (3) explore the role of intentionally mediated forms of communication.

Foraging and inertia: Understanding the developmental dynamics of overt visual attention.

During early life, we develop the ability to choose what we focus on and what we ignore, allowing us to regulate perception and action in complex environments. But how does this change influence how we spontaneously allocate attention to real-world objects during free behaviour? Here, in this narrative review, we examine this question by considering the time dynamics of spontaneous overt visual attention, and how these develop through early life. Even in early childhood, visual attention shifts occur both periodically and aperiodically.
