Tomer Ullman - 1) Whether and how infants understand unified notions of mass and force (central to the question of how babies understand intuitive physics) and 2) Do children understand 'cost' in a utility calculation as related to physical effort.  

Julian Jara-Ettinger - "Costs, rewards, and commonsense psychology" Abstract: Humans have a unique ability to reason about other people’s unobservable mental life. By simply watching someone’s actions we can infer what they think and what they want, we can predict how they might act in the future, and we can judge their actions as praiseworthy or condemnable. In this three minute presentation I will propose the hypothesis that at the core of social cognition is a naïve utility calculus that enables us to reason about how agents behave as a function of the costs and rewards associated with different outcomes.
