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.and his Ph.D. in Clinical Psychology from Southern Illinois University at Carbondale. He completed his predoctoral internship in the Department of Psychiatry at the Indiana University School of Medicine, in a 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, PSY 336 Ethics and Special Populations in 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 Playing Addiction & Urges - my lab is developing a standardized stimuli set to be used in this area of research
  • Assessing Psychological and Neurobiological Individual Differences in Cigarette and Caffeine 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 to validating or invalidating statements from peers after trauma, associations of alcohol use, hostility, or suicidality with psychological trauma/victimization)

Dr. Hammersley’s clinical training involved assessment and diagnosis of mental illness and substance abuse. Within those areas his interests involve studying the effects of smoking cessation or 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 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).
