The task of repeating 'puh-puh-puh' primarily informs us about which motor dimension?

• A. Language formulation
• B. Speech sequencing
• C. Respiratory endurance
• D. Speed and regularity of movement

Answer: (D)

The main idea tested is how quickly and how evenly you can perform a simple repetitive oral-motor action. Repeating “puh-puh-puh” requires rapid, smooth lip closure and release in a steady rhythm. Maintaining a consistent tempo and keeping the repetitions evenly spaced shows control over the speed and regularity of movement of the articulators. This focus on timing and pace reflects the motor dimension of speed and regularity of movement. It isn’t about planning what to say (language formulation), ordering different sounds (speech sequencing), or how long you can sustain breath (respiratory endurance).
