April Murphy

I am a grad student in the Knowledge & Concepts Lab. My research has been mostly concerned with the following:

  • Is math and number knowledge different from other kinds of conceptual knowledge?
  • Discriminative and generative models of arithmetic problem-solving. What kinds of predictive models do people form when learning how to solve math problems, and can we exploit these to improve learning and transfer?
  • Comparing corpus-based semantic representations to human semantic judgments — how reliable are natural language methods for predicting human behavior, and what are their limits?
