Which factor explains why growth spurts should be accounted for when applying norms to youth?

• A. Growth spurts can temporarily alter performance and must be accounted for when selecting norms.
• B. Growth spurts have no effect on normative interpretations.
• C. Growth spurts always improve performance.
• D. Growth spurts render norms unusable forever.

Answer: (B)

Growth spurts change a young person’s body quickly, so performance doesn’t track perfectly with age alone. When a child is growing rapidly, height and weight can increase faster than strength, coordination, or motor skills catch up, leading to temporary shifts in performance. Norms that are tied only to age can misrepresent where a youth truly stands if maturation isn’t considered. That’s why the factor to account for is how growth and maturation can temporarily affect performance, prompting the use of maturation-adjusted norms or interpretation that considers growth status. The idea that growth spurts have no effect, always improve performance, or render norms unusable forever doesn’t fit the dynamic nature of development.
