Harald:
Your point is very well taken. I am not up on the literature on
schema (I would say, "anticipatory constructions" and motor movements;
though it doesn't surpriser me to find that there is such literature.

Your point about needing to learn a new task on the basis of
existing constructs seems [to me] to be related to the thinking that has
grown from Vigotsky's kind of theorizing -- that having to do with the
"zone of proximal distance." Developing a new construction cannot take
place readily if the base of existing constructs is not already
available.
This idea, so far as PCP is concerned, relates to the core ideas
one uses when speaking of MEMORY PROCESSES. What is stored for use by a
system of constructs. I have proposed that we should think of storage
in terms of TWO POLED CONSTRUCTS. Thus, each anticipatory construction
-- whether it be a motor movement by which we anticipate a valid body
position, position of a putative object in space, or our self as text
for another to process -- represents a NEW constructions. That is,
constructions should not be taken as the unit of storage.
I have come to believe that this is a central issue in working
with PCP.

What you seem [to me] to be saying is that the people who have
built motor movement theories around notions such as schema or
anticipatory constructions, have tried to pass on to the learner the
complete construction, without ascertaining whether or not the person
has available the interconnected hierarchy of constructs out of which
he/she can build the construction to be used in the situation.
