Abstract

Findlay & Walker give voice to several common lines of thought regarding oculomotor control but do not provide sufficient detail for a critical evaluation of their theory. I argue that arbitrary spatial and temporal saccade metrics can be produced simply by manipulating the initial activation values in their model – values that the authors never specify. This lack of detail makes it difficult to anticipate the model's specific oculomotor behavior, or to compare this behavior to models opting for a more quantitative framework.
