"The Interplay between Prediction Errors, Twitter Mood, and Real-World Gambling”
Ross Otto, McGill University
A growing body of work reveals how unexpected positive outcomes can alter risk attitudes, presumably through changes in moods, resulting in increased risk-taking behavior. Moreover, the effect of these positive outcomes upon mood appears to be nuanced: an outcome exerts a stronger effect when it is unexpected rather than expected, and this manifests in both affective experience and momentary, subjective well-being. Here we examine how real-world unexpected outcomes can shift mood states which are observable at the level of a city, in turn predicting changes in consequential risk-taking behaviour. By analyzing mood language extracted from millions of daily, location-specific Twitter messages, we examine how real-world 'prediction errors' predict day-to-day mood states observable at the level of a city. Studying US six cities over two years, we reveal that day-to-day fluctuations in Twitter-inferred mood states could be predicted by prediction errors stemming from local sports and weather outcomes. These mood states in turn predicted increased per-person lottery gambling rates in a subset of these cities for which we could measure gambling rates, revealing for the first time the real-world interplay between prediction errors, moods, and risk attitudes. Our results demonstrate that fluctuations in mood states underlying real-world risk-taking behavior can be measured through social media.

Emotion Regulation and Eating Disorders: A Transdiagnostic Perspective
Sarah E. Racine, McGill Psychology
Eating disorders are serious psychiatric illnesses that are associated with excess morbidity and mortality as well as high costs to society. A better understanding of risk and maintenance factors that are both shared across psychiatric disorders and that are unique to eating disorders and their component symptoms can help advance prevention and treatment. My program of research aims to: 1) elucidate the biobehavioural mechanisms that underlie transdiagnostic risk factors and their relation to eating disorders, and 2) identify symptom-specific disease processes that influence the expression of psychopathology in the context of transdiagnostic risk factors. In this talk, I will review a series of studies using multiple methodologies (i.e., prospective longitudinal designs, behaviour genetic methods, psychophysiology paradigms) to consider emotion regulation as a key transdiagnostic process involved in the etiology and maintenance of eating disorders. I also will present findings indicating that eating disorder-specific risk factors (e.g., sociocultural appearance pressures) interact with emotion regulation to lead to eating disorder symptoms, but not symptoms of other psychiatric disorders. Finally, I will discuss future research directions that relate to expanding this transdiagnostic framework to include other forms of psychopathology and that will inform the development of mechanistically-based treatments.
