# Joint Attention Communication and Other Minds **Opening (not a real abstract):** Some time around their first birthday most infants begin to engage in a series of behaviours designed to bring it about—say, by means of pointing or gazefollowing—that their own and another person’s attention are focused on the same object. Described as manifestations of an emerging capacity for joint attention, such triangulations between infant, adult, and the world are often treated as a developmental landmark and have become the subject of intensive research among developmentalists and primatologists over the past decade. More recently, work on joint attention has also begun to attract the attention of philosophers. Fuelling researchers’ interest in all these disciplines, we find the intuition that joint attention plays a foundational role in the emergence of communicative abilities, in children’s developing understanding of the mind and, possibly, in the very capacity for objective thought.
