Abstract
This chapter argues that a central division among accounts of joint attention, both in philosophy and developmental psychology, turns on how they address two questions: What, if any, is the connection between the capacity to engage in joint attention triangles and the capacity to grasp the idea of objective truth? How do we explain the kind of openness or sharing of minds that occurs in joint attention? The chapter explores the connections between answers to both questions, and argues that theories can be divided into two distinct types according to how these connections are developed.
