Free will implicates inner speech via self-regulation

Free will typically refers to any form of significant control over one’s actions. This definition is remarkably similar to that of self-regulation—the control of one's behavior, emotions, and thoughts in pursuit of long-term goals. Indeed, several scholars have proposed that the latter constitutes the psychological equivalent of the former. A large body of empirical work demonstrates that both covert (inner) and overt (private) forms of self-directed speech are causally associated with self-regulatory outcomes such as action planning, problem-solving, emotion regulation, attention, cognitive flexibility, working memory, and self-reflection. It thus seems logical to propose that free will too recruits self-directed speech. This argument is explored by reviewing the relevant literature pertaining to free will, self-regulation, and inner/private speech.
