Additional Information

Education:

Dr. Jonathan Hammersley earned his B.S. in psychology from the University of Southern Indiana, in Evansville IN, and earned his M.A. in Adult Clinical Psychology and his Ph.D. in Clinical Psychology from Southern Illinois University at Carbondale. 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.”

Teaching:

Dr. Hammersley regularly teaches substance abuse 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) as well as courses such as Abnormal Psychology and Clinical Psychology. He also enjoys teaching undergraduate or graduate courses in psychological assessment.

Research Interests:

Dr. Hammersley’s clinical training is more specifically in assessment and 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 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 examining 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 the upcoming semester in which students can become involved, including research looking at patterns of drug and alcohol use and general health behaviors in college students and a study investigating psychological and neurobiological predictors of caffeine and cigarette use.
