The Clinical Science and Deception Lab was established in 2013 and is supervised by Dr. Drew Curtis. My research has focused on pathological lying, deception in healthcare and other relationships, and aspects of clinical science.
Current Research
-
The psychopathology of deception has received little attention. In 1891, Delbrück referred to pathological lying as pseudologia phantastica. Pathological Lying is not found in major nosologies such as the Diagnostic and Statistical Manual of Mental Disorders (DSM-5; APA, 2013). Recently, I proposed a theory of pathological lying (Curtis, 2019) by implementing the psychopathology criteria of the four Fs (Curtis & Kelley, 2016).
My recent work, with Dr. Chris Hart and Dr. Victoria Talwar, has been examining executive function deficits related to etiology. Additionally, I have been investigating differential diagnoses of pathological lying, cross-cultural prevalence, and empirically-supported treatments.
-
Our research examines various aspects of deception: psychotherapy (client and psychotherapist, health care professions, ethical use of deception, intimate relationships, parental relationships, attitudes, beliefs, attributions, motivations, effects of revealing lies, and scale development.
-
Our research examines various aspects of clinical science. Primarily this research examines psychomythology of psychopathology. We have also examined augmentative and alternative communication devices.

Savannah Torres, M.S.
I am a Counseling Psychology Psy.D. student at Angelo State. I work part-time as an LPC-Associate and currently do my doctoral practicum at Goodfellow Air Force Base, collaborating with licensed psychologists to support service members through assessments, fit-for-duty evaluations, and ongoing counseling. Since the 2023 school, I have been involved in Dr. Curtis’ research on pathological lying, where we’ve been exploring the complexities of lying and deception. Moving forward, we hope to contribute to future literature that could enhance diagnostic and treatment options for those affected by these matters and I look forward to the findings we continue to explore and discover!
