In AOS assessment, how do errors typically behave across repeated attempts, especially with longer or more complex utterances?

• A. Errors become absent with repetition.
• B. Errors are completely random across attempts.
• C. Errors tend to be inconsistent and more variable with longer/complex utterances, with frequent groping.
• D. Errors are always identical on every attempt.

Answer: (C)

In apraxia of speech, the way errors show up across repeated attempts reflects a motor planning disruption. When someone tries to repeat the same long or complex utterance, the coordination of speech sounds and sequencing becomes unstable, so errors don’t stay the same from trial to trial. You’ll see substitutions, distortions, and pauses shift around as the speaker searches for the right articulatory plan. This instability is often accompanied by groping—the speaker visibly or audibly searching for the correct place and manner of articulation. So, errors are inconsistent and more variable with longer or more complex utterances, with frequent groping.

Why the other ideas don’t fit: errors that disappear with repetition would imply a recovery to normal speech, which isn’t typical in AOS. errors that are completely random ignore the systematic patterns seen in motor planning breakdown. errors that are always identical contradict the hallmark variability of apraxic speech.
