This reduction of the P300 component is now considered a biomarker of schizophrenia. Roth has also applied the use of skin conductance, electrocardiography, actigraphy, and monitoring of other physiological functions, such as respiration, to assess anxiety disorders.〔(Stanford faculty page ).〕 In addition, Roth co-authored the (''Core Concepts in Health'' ) textbook series,〔(Core Concepts in Health Brief ).〕 as well as over 250 scholarly journal articles and book chapters.〔〔 Roth is currently semi-retired, but continues research work on the psychophysiology of hyperarousal and posttraumatic stress disorder, as well as ambulatory monitoring of sleep.〔(Post Traumatic Stress Disorder Hyperarousal Symptoms Treated With Physiological Stress Management ) .〕
