[visionlist] microsaccades during free viewing

[Eileen Kowler]

Reply to:  Francisco Flores's query about the rate of microsaccades in 
free visual exploration:

A number of studies have examined the frequency of occurrence of 
microsaccades  in a variety of visual tasks, including fixation with the 
unrestrained head and reading.   In agreement with your observations, 
microsaccades were exceedingly rare and played no role in performance of 
the various visual tasks.  For details, see the references below.
