Are AOS errors generally consistent or inconsistent in their location within utterances?

Are AOS errors generally consistent or inconsistent in their location within utterances?

• A. Consistent
• B. Inconsistent
• C. Random
• D. Semantically driven

Answer: (A)

In apraxia of speech, the problem is in planning the sequence of movements for speech. Because that planning follows a fixed motor sequence, the spots in the utterance that are hardest tend to fail in the same places across attempts. So you often see errors recur at the same location within words or syllables, even if the exact sound that distortions take can vary. This stable pattern reflects a planning bottleneck at a particular position in the motor sequence. If errors appeared in random places or were driven by meaning rather than motor planning, that would fit other explanations better, whereas the consistent location of errors supports a planning-based disturbance.
