Addictive Behaviors Laboratory

Principal Investigator: Dr. Alison Looby



Research Focus

My laboratory broadly examines substance use behaviors, with a focus on college student alcohol, marijuana, and stimulant use. Much of our research aims to examine and subsequently modify cognitive mechanisms underlying substance use, including expectancy effects, motives, and neuropsychological functioning. Research in my laboratory tends to be experimental and laboratory-based, though we are also employing some naturalistic methodology. Selected recent research studies in my laboratory include:

-An examination of the interactive effects of working memory depletion, negative affect, and negative urgency on ad lib drinking

-An examination of subjective mood and neuropsychological performance as a function of stimulant type and expectancy

-An event-level examination of the impact of alcohol use, drinking motives, and environmental cues on likelihood of risky sexual behavior

-A randomized, controlled trial to test the efficacy of a combined expectancy modification and harm reduction intervention to prevent nonmedical prescription stimulant use among at-risk college students

-An examination of the interactive effect of cue exposure duration and behavioral activation sensitivity on craving for and attentional bias toward alcohol

Lab Members:

Alison Looby

Alison Looby, PhD

Dr. Looby grew up in southern California and earned her BA in psychology from the University of California, San Diego in 2002. She earned her PhD in clinical psychology from the University at Albany, SUNY in 2011. After spending some time teaching at the University of North Dakota, Dr. Looby joined the faculty at the University of Wyoming in 2016. Her primary research focus is with regard to nonmedical prescription stimulant use among college students and understanding factors related to use, including placebo effects, expectancy effects, and neuropsychological functioning. Dr. Looby spends her free time with her family (including 2 young children and 2 dogs) and enjoys hiking, snowboarding, and traveling.


Lauren ZimmermanLauren Zimmerman, 3rd year graduate student

Lauren was born and raised in west central Minnesota before obtaining her BA in psychology from the University of North Dakota in 2014. She is currently a 3rd year graduate student in the Clinical Psychology PhD Program at the University of Wyoming. Her broad research interests include factors related to substance use (e.g., motives, self-efficacy, expectancy effects) and intervention and prevention efforts to decrease use.  Lauren enjoys sports, spending time with family and friends, and traveling in her free time.




 caitlin falcoCaitlin Falco, 2nd year graduate student

Cait was born and raised in the suburbs of Chicago before earning her B.S. in Psychology from Indiana University Bloomington in 2016. She is now a 2nd year graduate student in the Clinical Psychology PhD Program at the University of Wyoming. Her research interests include understanding the mechanisms (e.g., executive functions, motives, attention) underlying substance use and how to target these mechanisms to reduce and/or prevent substance use, as well as how these factors are related to other risky/externalizing behaviors. In her free time, Cait can usually be found with her dog.



Nick Livingston

 Nick Livingston, 1st year graduate student

Nick was born and raised in Oregon's Willamette Valley before earning his BS in psychology from the University of Oregon in 2017. He is currently a 1st year graduate student in the Clinical Psychology PhD Program at the University of Wyoming. His research interests involve understanding factors implicated in substance use initiation, consequences of substance use (e.g., cognitive performance, subjective effects, mood), and how drug use can be modified through targeted interventions. During his free time, Nick enjoys the company of family, snowboarding, and traveling.
