Which of the following is NOT a FMV characteristic attributed to children?

• A. Running/playing
• B. Shorter than adults
• C. Able to talk to non-familial adults
• D. Longer stride

Answer: (D)

The important idea here is how growth affects movement. A child’s stride length is mainly determined by leg length and overall body size. Since kids are shorter and have shorter legs than adults, their stride is shorter, not longer. So claiming they have a longer stride doesn’t fit with how movement scales with body size. The other traits—engaging in running and play, being shorter than adults, and talking with non-family adults—are consistent with typical pediatric behavior and development.
