title: Tests of Hering- and Helmholtz-type models for saccade-vergence interactions by comparing visually guided and memory-guided movements.
abstract: We compared the dynamic properties of memory-guided and visually-guided saccade-vergence movements. For memory-guided responses, convergence components were slowed proportionally more than corresponding saccadic components, compared with visually-guided responses. This result is consistent with independent saccadic and vergence systems, and supports a Hering-type model for saccade-vergence interactions.
