Subclaims¶

q2 i? Repeated mental and physical testing of average and superior children suggested that the mental growth curves of superior children diverge from those of average children, and that mental curves resemble and run parallel to physical curves. → Frank N. Freeman 1924

q2 · i? · associational · r?

Meeting report of Baldwin and Stecher's graphed results of repeated mental tests and repeated physical tests of average and superior children; findings are reported as suggested by the curves, with no statistics printed.

"The results suggested that the mental growth curves of superior children diverge from those of average children, and that mental curves resemble and run parallel to physical curves."

Discussion¶

Related Claims¶

• Average and superior children develop at different levels and grow increasingly dissimilar with age, with superior children showing adolescent mental acceleration about one year earlier — possibly the same claim (merge candidate)
• Physiologically accelerated children are mentally accelerated: height correlates with mental age +0.53 for 49 girls with age held constant — a narrower finding that bears on this claim
• In a prospective longitudinal sample (ECLS-K:2011), numbers reversed performance follows a logarithmic growth pattern, decelerating over ages 6–11 — related
• Verbal working memory shows non-linear growth from ages 3–19, with the most rapid growth during childhood and a brief accelerated period during early adolescence — related
