Recent research shows how poor
motor control is linked to challenges
with many other skills. This study
makes the point that the evaluation
of retained primitive reflexes may be
an important indicator of atypical
development such as that seen in
autism.

". . .findings suggest that the
persistence of primitive reflexes
might alter the developmental
trajectory of future motor ability
and therefore their evaluation might
be an early indicator of atypical development."
