Abstract: The present study examined three aspects of motor programming (generalized
motor programme (GMP) accuracy, temporal parameterization accuracy, and
amplitude parameterization accuracy) in subjects with apraxia of speech (AOS)
or conduction aphasia (CA) and normal speaking participants. Subjects were
presented with a movement pattern on a monitor that they were required to
produce with the jaw, after the target pattern had been removed from view.
Analyses examined differences in relative (parameterization) and absolute
(GMP) timing and amplitude between the target and actual movement.
Examination of individual subject performance revealed inter-subject variability
within the AOS group, with two of the four subjects demonstrating
unimpaired GMP accuracy but poor parameterization accuracy, while the other
two subjects exhibited the opposite pattern, impaired GMP accuracy but
normal parameterization. No clear pattern of deficit was noted for the subjects
with CA. Results are discussed with respect to motor control theories of AOS
and CA.
