Which task is most challenging due to motor planning demands?

• A. Monosyllabic word repetition
• B. Familiar automatic sequences
• C. Multisyllabic or complex words
• D. Nonverbal imitation

Answer: (C)

Motor planning demands rise with longer, more complex speech sequences. Multisyllabic or complex words require planning a longer chain of articulatory movements, precise timing, and careful coordination of the lips, tongue, and jaw across multiple phonemes and syllables. That increased sequencing and motor programming load makes this task the most challenging. Short, monosyllabic repetitions rely on simple, well-practiced patterns, and familiar automatic sequences are highly overlearned, so they depend less on fresh motor planning. Nonverbal imitation can involve some sequencing too, but when producing speech, the key challenge is constructing and managing the longer, more intricate motor plan needed for multisyllabic words.
