# Neural Bases of Disgust Conditioning in Anorexia Nervosa

> **NIH NIH K23** · UNIVERSITY OF MINNESOTA · 2022 · $164,160

## Abstract

PROJECT SUMMARY/ABSTRACT
 This K23 application aims to support Dr. Lisa Anderson to achieve her overarching goal of establishing an
independent, patient-oriented research career that will (a) elucidate biological and psychological mechanisms
associated with risk and maintenance of eating disorders, and (b) use this information to develop and optimize
precise, efficacious treatments for eating disorders. The proposed application will strengthen Dr. Anderson’s
abilities to meet her career goals by providing advanced training designed to: (a) develop expertise in theory
and assessment of disgust conditioning mechanisms involved in transdiagnostic models psychopathology
characterized by avoidance behaviors, and to translate this knowledge to research for eating disorders; (b)
gain knowledge and skills in neuroimaging methods necessary to conduct independent research investigating
the neural substrates of disordered eating; and (c) obtain advanced training in analysis of neuroimaging (fMRI)
data required to independently examine maintenance mechanisms underlying eating disorders across various
units of measurement (i.e., psychological-, behavioral-, physiological-, and neurobiological-level variables). Dr.
Anderson has assembled a team of experts who will provide training to accomplish the proposed training goals
and scientific aims. The core mentorship team consists of Dr. Scott Crow (training in translational eating
disorders research), Dr. Kathryn Cullen (neuroimaging training), Dr. Mark Fiecas (biostatistics), Dr. Shmuel
Lissek (cross-diagnostic models of disgust learning), and Dr. Thomas Hildebrandt (translation of disgust
learning models to eating disorders, computational modeling of aversive reinforcement learning in anorexia
nervosa [AN]). Dr. Kelvin Lim will consult on neuroimaging study design and R01 application preparations. Dr.
Carol Peterson will consult on emotion regulation models and emotion-based mechanisms research for eating
disorders. Dr. Josh Cisler will consult on disgust-based task design and computational models of aversive
reinforcement learning. As part of her training, Dr. Anderson will complete a two-part study. Study 1a will
compare patterns in neural activation during a food-specific disgust generalization and extinction task between
individuals with AN and non-eating-disorder comparison participants to establish the extent to which the neural
substrates of food-specific disgust generalization and extinction specifically relate to food avoidance and
restrictive eating severity in AN. In a longitudinal arm, Study 1b will determine the extent to which neural
activation patterns associated with disgust generalization and extinction predict later AN maintenance. Overall,
in addition to supporting Dr. Anderson’s training goals, this project will meet a critical need by identifying
disgust conditioning mechanisms that may underlie food avoidance symptom severity and disorder
maintenance in AN. This knowledge will ultimately in...
