Research Interests:
My areas of expertise within the interdisciplinary field of cognitive science are cognition, psycholinguistics, categorization, and reasoning. My research program focuses on semantic/conceptual/categorical structures inherent in judgement and reasoning processes in adults and children.

Some ongoing projects include:

  • Patterns of inductive judgements in racial and gender categories
  • The "Someday, so sooner" fallacy
  • Category based induction
