John’s primary interest is in how humans and animals come to know about their world. This question spans phenomena as diverse as simple conditioning processes to the workings of science, and perspectives as different as evolutionary psychology and neural network accounts of learning. He has conducted research on decision processes in rats, chaotic behavior in pigeons, complex discrimination in humans, and how people detect change in causal systems.
