Functionality of automaticity of saccades
The role of saccadic automaticity could be more clear if we take into consideration
the fact that organs of sense are more susceptible to dynamic processes than to static
ones. Due to saccadic automaticity a static perception of the world even under complete
immobility of the environment and the subject is practically and completely excluded.
The parameters of saccadic automaticity are correlated with many neurophysiological data,
in particular, with the length of visual persistence and duration of the microact of visual
information processing on all levels. (Lebedev A.N., 1980; Podvigin N.F., 1979; Podvigin
N.F., Makarov F.N., Shelepin Yu. E., 1986).
Under natural conditions due to saccadic automaticity on- and off- systems work in
their own regime providing a permanent afferent stream ample for a reliable reception
of all nuances of a visible picture and simultaneously it guarantees a continuity of
visual perception. In pathology, in persons with an immobile eyeball, evidently, there
is no such a guarantee, though a visual function is preserved. Saccadic automaticity as
an active mechanism improves a visual apparatus in the process of ontogenesis and forms
conditions for consolidation of sensor and motor apparatus in a single functional system,
(Sudakov K.V., 1988) which attains perfection to the end of the first year of a child's
life. Saying figuratively, saccadic automaticity "polishes" a visual organ transforming
it into a perfect sensor system.
