Jonathan J. Hammersley, Ph.D
157 Waggoner Hall
Dr. Jonathan Hammersley earned his Bachelor’s of Arts from the University of Southern Indiana, in Evansville IN, earned his M.A. in Adult Clinical Psychology from Southern Illinois University in Carbondale IL and received his Ph.D. in General Clinical Psychology from Southern Illinois University in Carbondale IL. He completed his internship in the department of Psychiatry at the Indiana University School of Medicine, research/academic track. His dissertation was titled “Modulation of covert attention by emotion: Automatic processing of emotional versus neutral cues in a covert attention task.”
Dr. Hammersley regularly teaches the substance abuse program CADC courses:PSY 334 Perspectives on Substance Abuse, PSY 335 Substance Abuse Assessment, Education and Case Management, PSY 336 Ethics and Special Populations in Substance Abuse Treatment, PSY434 Substance Abuse Treatment Approaches and Techniques I, PSY 435 Substance Abuse Treatment Approaches and Techniques II, PSY 436 Substance Abuse Practicum. He also enjoys teaching courses in psychological assessment, abnormal psychology, graduate psychopathology, and clinical research.
Dr. Hammersley’s training is clinical psychology and more specifically, diagnosis of mental illness and substance abuse. Within those areas his interests involve studying the effects of smoking cessation and drugs such as nicotine and caffeine, as well as examining specific emotional and cognitive mechanisms for substance use/abuse and psychological disorders. Much of his clinical work and research has involved cognitive and emotional assessment, and figuring out ways to study the intersection of cognition and emotion (i.e., emotional distractibility and cueing mechanisms that may lead to or maintain psychopathology or drug craving). He is particularly interested in studying substance use/abuse, including smoking, in relation to psychological disorders (i.e., ADHD) and mental health symptoms (i.e., depression or anxiety). He hopes to have several projects underway in upcoming semesters in which students can become involved, including research looking at patterns of drug and alcohol use and general health behaviors in college students who report having been physically victimized or traumatized, anxiety in relation to smoking and brief interventions for smoking cessation, and exercise ability in adults who smoke, to name a few.
