Attention, Joint Attention, and Social Cognition.

Before social cognition there is joint processing of information about the attention of self and others. This joint attention requires the integrated activation of a distributed cortical network involving the anterior and posterior attention systems. In infancy, practice with the integrated activation of this distributed attention network is a major contributor to the development of social cognition. Thus, the functional neuroanatomies of social cognition and the anterior-posterior attention systems have much in common. These propositions have implications for understanding joint attention, social cognition, and autism.
