Multiple Choice

A child practiced the /ɹ/ phoneme 10 times each day during 5 minute sessions before class, 5 days per week for 10 weeks. What was the cumulative intervention intensity?

Cumulative intervention intensity is the total number of practice opportunities (doses) delivered across the intervention period. The child did 10 doses per day, 5 days a week, for 10 weeks, so total doses = 10 × 5 × 10 = 500. That makes 500 doses the correct measure of cumulative intensity.

The other options describe duration (ten weeks), number of sessions (50), or approximate calendar time (three months) but don’t reflect the total amount of practice opportunities provided.
