I am a PhD candidate in the Early Childhood Cognition Lab and the Computational Cognitive Science group at the department of Brain and Cognitive Sciences at MIT. I study how humans interpret other people's behavior to infer their competence and preferences (Jara-Ettinger, Gweon, Tenenbaum, & Schulz, 2015) and how they use these inferences to make social evaluations (Jara-Ettinger, Tenenbaum, & Schulz, 2015). In parallel, I study how children learn numerical concepts (Jara-Ettinger, Piantadosi, Spelke, Levy, & Gibson, under review) and the influence these concepts have on social tasks (Jara-Ettinger, Gibson, Kidd, & Piantadosi, under review).
