Additional Information

Education:

Dr. Jonathan Hammersley earned his B.S. in psychology from USI in Evansville IN, and earned his M.A.and his Ph.D. in Clinical Psychology from Southern Illinois University at Carbondale. He completed a predoctoral internship in the Department of Psychiatry at Indiana University School of Medicine, in a research/academic track, and a postdoc in neurocognitive disability assessment. 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 courses in substance abuse (e.g., PSY 334 Perspectives on Substance Abuse, PSY434 Substance Abuse Treatment Approaches and Techniques) as well as Abnormal Psychology (PSY 424) and Clinical Psychology (PSY 380). He also enjoys teaching undergraduate or graduate courses in psychological assessment.

Service:

Recent service includes the department grade appeals committee, the UPI Student Evaluation Committee, the Center for Innovation in Teaching & Research Advisory Board, the Psychology Dept. Awards Committee and Teaching Evaluation subcommittee, the Recruitment Committee, the Experimental Psychology Master's Steering committee, the College Attraction/Retention of Students committee, and the Midwestern regional Psi Chi Steering Committee.

Research Interests:

Some Recent or Current Projects:

  • Video Game Addiction & Urges - my lab is developing a standardized stimuli set to be used in this area of research
  • Psychological and Neurobiological Individual Differences in Substance Use.
  •  Patterns Of Substance Abuse, Trauma, and Mental Health Symptoms in College Students.
  • Clinical Treatments / Psychotherapy Outcomes (e.g., mental health patterns in first generation college students, correlates of worsening symptoms during psychological treatment)
  • Responses to Trauma/Victimization (e.g., responses peer statements after trauma, associations of alcohol use, hostility, or suicidality with psychological trauma/victimization)

 Much of his clinical work and research has involved 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, including smoking, in relation to psychological disorders (i.e., ADHD) and mental health symptoms (i.e., depression or anxiety).
