ABSTRACT
This chapter explores the tools infants need in order to build an understanding of other people's actions and emotional reactions, and examines how infants put these tools to work. It also examines how infants use gaze to acquire additional information about objects and how they then apply that information to their own actions. Picking up the gaze-following tool for use in triadic interactions will certainly put 10-month-olds that much closer to making the object-emotion link in our studies. The tools of gaze-following and sensitivity to emotions may be available to the 10-month-old, but it may be only with exposure and practice that infants are able to use them in concert and use them consistently. The infants needed to recognize the emotion, follow the actor's gaze, connect the emotion to the object, and finally remember everything over a short delay in which infants experienced other emotions.
