Merrill Hiscock

Professor Emeritus
Ph.D., University of Texas at Austin

Biographical Summary

Joined University of Houston faculty in 1989 following 13 years as a clinical neuropsychologist in a Canadian medical school. Working to develop experimental paradigms that can be applied both to normal and clinical populations. Special interest in cross-coupling of behavioral systems, e.g., interference between cognitive and manual activities; association between cognitive processes and eye movements. Dr. Hiscock is also affiliated with the UH Center for Neuro-Engineering and Cognitive Science.
