The Impulse Lab at George Mason University is a part of the clinical psychology department and includes Sarah Fischer, Ph.D., as the Principal Investigator. Our lab conducts research studies on binge eating, purging, and alcohol abuse. We examine how personality traits influence these behaviors through deficits in emotion regulation, impulse control, and reward seeking. Current research studies include: -Food Cues & Stress Study -Challenging Societal Ideals: Understanding the Behavioral Mechanisms of Cognitive Dissonance

Our very own Lauren Langston presenting the work identifying the bidirectional nature of Eating Disorders and Autoimmune Disorders. Her work was completed at Karolinska Institute in Sweden as part of the National Science Foundation GROW Fellowship. Did we mention she won the Best Student Abstract Award for this work at the Eating Disorders Research Society Conference in Leipzig Germany!? We are very proud of you Lauren!

Brain scans show how bulimic women respond to food when stressed

New article from the Daily Mail highlighting recent work by the Impulse Lab. Using brain imaging, we showed that when patients with #bulimia experience stress they respond to food cues uniquely. Just in time for the release of Netflix #ToTheBone. #eatingdisorders https://t.co/oHzrTPsInw

A recent study by the American Psychological Association suggests that women with bulimia nervosa may use food to avoid negative thoughts about themselves.

Joanne will be attending graduate school at VCU! Congrats, Joanne!

I am a senior pursuing a B.S. in Psychology. I am interested in the composition of dreams and the neurobiological basis of addiction and how that relates to personality and impulsive behaviors, specifically criminal behaviors.

The focus of my program of research is on personality traits and psychosocial factors influencing the co-morbidity and maintenance of addictive behavior patterns. Specifically, my research investigates how different aspects of the broad trait impulsivity affect substance use and eating disordered behavior, such as binge eating and purging. I am especially interested in how the personality trait of impulsivity affects these behaviors in the context of negative mood states and in conjunction with outcome expectancies for addictive behaviors. A second interest is in mindfulness based interventions, as they may be particularly relevant for harmful behaviors that occur in the context of emotion dysregulation.

Alison Ruckstuhl is a senior Psychology major working as a research assistant in the Impulse Lab. Alison is currently assisting with research looking at cognitive dissonance and its subsequent effects on behavior and attitudes. Additionally, Alison is completing her honors thesis in the lab, examining the relationship between internalized and externalized attitudes toward overweight or obese status. She plans to pursue a Ph.D. in Cognitive/Behavioral Neuroscience, where she will pursue neurobiological factors underlying issues of 1) negative affect in response to real or perceived obese status, 2) fear response to real or perceived obese status, and 3) factors contributing to self-regulation as applied to eating behaviors.

Maggie is now pursuing her Ph.D. at the University of Cambridge! Congrats, Maggie.

Maggie Westwater worked as a research assistant in The Impulse Lab. She graduated with a Bachelors of Science in Neuroscience from George Mason University in December 2014. Maggie has been heavily involved with an fMRI study of the effects of stress and food cue-reactivity on cognitive processing. Maggie hopes to pursue a doctoral degree in clinical psychology where she will pursue translational research of: 1) the neurobiological mechanisms of eating and addictive behaviors, 2) the implications of impulsivity and distress tolerance in psychopathology, and 3) novel assessment of impulsive behaviors in daily life.

Our lab is actively recruiting for the following study!

Earn up to $350 in the Food Cues & Stress Study

Do you lose control over your eating or binge eat? Are you a woman between the ages of 18 and 45 years old with a body mass index (BMI) between 18.5 and 29.9? Do you engage in some sort of behavior to compensate for binge eating?

If you answered yes to these questions, you may be eligible to participate in the Food Cues & Stress Study at George Mason University. The Impulse Lab is currently conducting a multi-method study of eating behavior, and participants will earn up to $350.00 for their participation. Participants will be asked to complete:

- A clinical assessment
- A functional magnetic resonance imaging (fMRI) scan
- A two-week protocol in which you respond to prompts on your smartphone

If you are interested in participating, please e-mail us at [email protected] or call (571)766-6390 for more information and to schedule a phone screen.
