Express saccades and visual attention

Fischer, B. and Weber, H. (1993) Express saccades and visual attention.

Short Abstract:

One of the most intriguing and controversial observations in oculomotor research in recent years is the phenomenon of express saccades in man and monkey. These are saccades of so extremely short reaction times (100 ms in man, 70 ms in monkey) that some experts on eye movements still regard them as artifacts or anticipatory reactions that do not need any further explanation. On the other hand, some research groups consider them to be not only authentic but also a valuable means of investigating the mechanisms of saccade generation, the coordination of vision and eye movements, and the mechanisms of visual attention.
