We have been learning and storing motor patterns in the Mixer since birth.
Bit by bit we added and combined short motor patterns, like "pa" into longer ones like "pa pa."
From there it was a short leap to,"pa pa give..." And then, "Papa please give me the keys to the car!"
Of course, mixer patterns are not restricted to speech acts.
They relate to all motor activities like eating, dressing, walking, playing an instrument, performing a dance, sports, etc.
Obviously this is a major memory commitment with its processes of retention and retrieval, and if problems occur in this area, strange and debilitating behaviors may result.
Disorders of the mixer, where the wrong motor pattern is elicited is called Apraxia.
It‰s analogous to having a jukebox retrieve the wrong record. You can get a tiny feel for this problem with the following exercise.
