The INSIGHT (Interdisciplinary Studies in Child Cognitive Growth) Lab at the University of Pennsylvania is dedicated to understanding children’s diverse thought processes and identifying the most effective strategies to nurture their cognitive development. We particularly focus on children's understanding of mental states (Theory of Mind) and their ability to regulate their attention, thoughts, and behaviors (Executive Function). We consider these cognitive abilities as fundamental mechanisms through which children interact with the world around them and navigate their developmental journey. By utilizing interdisciplinary studies that integrate behavioral, computational, and neuroimaging methods, we investigate the dynamics of child cognitive development. Ultimately, our mission is to provide actionable insights that guide every child through a fulfilling journey of growth, providing them with the opportunity to unlock their full potential.
