What is the approximate normal MAF CPM for a 6-year-old?

• A. 4 CPM
• B. 6 CPM
• C. 8 CPM
• D. 10 CPM

Answer: (B)

This question tests age-appropriate norms for this binocular-vision measure. As children develop, their ocular motor control and ability to rapidly alternate fixation while preserving fusion improve, so the cycles-per-minute rate climbs with age. For a six-year-old, about 6 cycles per minute is the typical, normal value. Values much lower (around 4 CPM) suggest slower performance, while higher values (8–10 CPM) are more characteristic of older children or adults. So, 6 CPM best matches normal development at this age.
