Dr. Kai Ling Kong’s research focuses on the prevention of obesity during infancy, in particular, targeting the development of eating behaviors in infants and toddlers. The obesity epidemic spares no age groups, and rapid weight gain during the foremost years is of utmost importance to treat, since its prevalence and severity generally increase with age. Therefore, early preventive strategies that positively impact weight and behaviors that lead to obesity, are imperative. The premise of my work is grounded in the behavioral economics framework and necessitates valid early measures of food and non-food reinforcement. Based on this framework, an individual’s choice to obtain commodities, such as food or fun activity is influenced by the constraints on those choices, as well as the availability of alternatives surrounding him/her. Secondly, the premise of my work is also grounded by research on environmental enrichment, and principle of choice architecture. Literature in these two areas suggest that arrangement of one’s physical environment, such as increasing the availability of choices, substitutability between reinforcers and constraints on complements to eating, can be used to make healthful lifestyle choices more obvious and accessible.
