Research and Teaching Interests
My research interests center on the origin of mental representations. I divide this issue into two parts. The first is causal induction. How do people come to know that one thing causes another? Some sequences of events are merely associated; others are causal. How do people tell such sequences apart?
The second issue is category formation. Objects in the world can be partitioned in an indefinitely large number of ways (e.g., objects that move in the wind, objects that have legs, objects to be avoided, and so on). Out of these, only a tiny fraction are commonly used (e.g., vehicles, bears, musical instruments). Why do people have the folk categories that they have, rather than the vast array of logically possible categories that they do not have?
The link between the two issues is that most categories are causal. I primarily develop theories from a computational perspective, and conduct cognitive experiments on normal adult humans. But I also consider a wide range of approaches to the underlying issues, including developmental, artificial intelligence, philosophical, and neural approaches. I am also interested in analogous issues involving nonhuman species.
