Inability to perform speech movements despite comprehension is called which term?

• A. Dysarthria
• B. Apraxia of speech
• C. Aphasia
• D. Circumlocution

Answer: (B)

The key idea here is distinguishing a motor planning problem from a language or muscle execution problem. When a person understands what they want to say but cannot coordinate the movements needed to produce the speech sounds, that points to a motor speech planning disorder. This specific difficulty is called apraxia of speech. In apraxia of speech, you’ll often see effortful, halting speech with distorted sounds and groping for the correct articulatory movements, while comprehension remains relatively intact.

Dysarthria would involve trouble with the actual execution of speech movements due to weakness or incoordination of the speech muscles, leading to slurred or imprecise speech, but the underlying planning is preserved to some degree. Aphasia is a language disorder; it affects understanding, production, or both of language content, not just the motor sequencing of speech. Circumlocution is a compensatory speaking strategy used to describe or talk around a word, typically seen in language disorders rather than a pure motor planning issue.
