Repeated behaviors are common in people with and without unusual
labels. For instance, thumb twirling, rocking, and the kicking of infants
are sights everyone has seen.
In autism and with people who are retarded, flipping of fingers,
body rocking, face slapping, and repetition of words and /sounds is common.
If the observed rate of sterotypical behavior in persons with
autism is .26 seconds per body rock, what brain wave might be implicated,
assuming that the loci of control are not modulating the motor program?
What brain wave --alpha, theta etc-- corresponds in duration in a direct
or multiple way to .26 seconds. Or is this approach not useful for
explaining the duration of the motor program which seems almost certainly
not to be under the conscious control of the infant kicking or the person
