Perceptual
trace: reference input into comparator.

Memory
trace - motor commands for a given
movement.

You may
lack either trace.

How
learning proceeds:
|
|
|
|
u |
the
VERBAL-MOTOR stage:
|
|
|
|
v |
subject
is without perceptual trace.
|
|
|
|
v |
subject
is unable by self to judge improvement.
|
|
|
|
v |
improvement
depends upon KR.
|
|
|
|
u |
the
MOTOR stage.
|
|
|
|
v |
the
subject has a good perceptual trace.
|
|
|
|
v |
external
feedback is practically unimportant.
|
|
|
|
v |
behavior
can still improve even without external KR.
