In this show we focus on the concept of private speech and its relationship to the “executive function.” Private speech is a form of communication in which the individual uses language to speak to him or herself for the purpose of comfort, guidance, and/or direction. Private speech is linked to the development of the executive function, which is a cognitive ability responsible for goal setting and realization. We will discuss the importance of private speech and executive function in adulthood and the role that it plays in the good and flourishing life.
