Multiple-Task Interference

Can people really do two things at once? In some sense, the obvious answer is "yes, of course." In others, it is not entirely clear. The extent to which multiple tasks interfere is clearly related to whether those tasks require the same cognitive-perceptual-motor resources. With ACT-R, we have been able to show that even if the central cognitive system is single-channel, it is possible to achieve very little cross-task interference.

Cognitive Architectures

We have an active interest not just in ACT-R, but in cognitive architectures and other formal (i.e., mathematical/computational) methodolgies in general and how they can be used in human factors/HCI.
