Psychological Studies of Visual Cortical Function

Abstract

We have investigated a number of paradigms where odd targets have to be either detected or discriminated and where set size, prior knowledge of target identity, and other factors were varied. We have set up an eye movement monitoring experiment to use the speed and accuracy of saccades to supplement the psychophysical observations described above. We have been examining the phenomenon of color (or brightness) spreading, developing a paradigm to show that the filling of color could be interrupted by using an after-coming patterned mask. We are also making neutral models to account for the psychophysical observations as they emerge. Keywords: Visual cortex; Eye movements.
