I use diverse research methods, including computational modeling, analysis of naturalistic behavior, and human experimentation. I use these techniques to investigate a diverse range of language-related phenomena with students and collaborators: conversation, thinking in language, sentence processing, word categorization, and even deception. For example, with Daniel Richardson, I have studied how people become coupled together during linguistic interaction (such as in their eye movements). I have also investigated how complex thinking unfolds in time by tracking the dynamics of people's arm movements (by using, for example, the Nintendo Wii Remote). My work is motivated by the ideas and tools used in the study of complex dynamical systems. I have recently been interested in theoretical issues tying together dynamics with classical theories of cognition in a more pragmatic, plural approach to cognitive science (check out this special issue).
