Glyn W Humphreys was born in 1954. He is currently Professor of cognitive Psychology at Birmingham University, Birmingham, England.

His main interests lie in visual cognition, particularly visual attention, shape and object recognition, and the linkage between perception and action.

In recent years with access to improved imaging facilities he has been a leading figure in the field of visual brain mapping, relating cognitive models to brain activity using PET and functional MRI scanning
