Joint Attention: Perception and Other Minds

From care-giver and infant playing with a toy, to singing duets or playing basketball, we frequently and effortlessly coordinate our attention with others towards a common focus. Joint attention plays a fundamental role in our social lives: it ensures that we refer to the same object, develop a shared language, understand each other and coordinate our actions.

This project aims is to elucidate the relational nature of joint attention, and its functional significance for social cognition, including cases involving different sense modalities and more complex forms of joint activities.

The project's subgoals are to:

  • clarify the role of perceptual experience for characterising joint attention;
  • propose a functional framework to assess multisensory contributions to establishing and maintaining joint attention;
  • test the hypothesis that engaging in joint attention can affect the processing of multisensory information.
