Is the working definition of applied psychophysiology proposed by Schwartz too narrow/restrictive?

This paper raises issues in further refining the working definition of "applied psychophysiology" proposed by Schwartz (1999). Issues to be addressed include defining what the word "psycho" means within the definition of applied psychophysiology and the implications of this word in practice. Other issues discussed include the meaning of the word "applied," and how incorporating the acquisition of self-regulatory skills or behaviors as one aspect of the definition of applied psychophysiology would help differentiate applied psychophysiology from other specialty areas. Finally, a revised definition is proposed to stimulate further discussion.
