Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q2 i2 For 49 girls, partial correlation (with age constant) between height and mental age is +0.53, between height and weight +0.57, and between height and ar-ray +0.52, indicating physiologically accelerated girls are mentally accelerated. → Bird T. Baldwin 1922

q2 · i2 · associational · r2
Partial-correlation analysis of height, weight, carpal-bone area and Stanford-Binet mental age for 49 girls examined at Iowa City. The printed effect size is r = +0.53 for height and mental age with age held constant (the author reports "For height and mental age the coefficient is +0.53").
"The coefficient for the group of 49 girls by the method of partial correlation (with age constant) is between height and weight +0.57; between height and ar-ray +0.52. For height and mental age the coefficient is +0.53."
Discussion¶
Related Claims¶
- Tall, heavy children with good lung capacity are further along toward mental maturity as evidenced by school progress, based on 21,682 final term grades — related
- 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 — related
- Group averages are misleading when applied to individual pupils because of extensive overlapping in weight and height across grades — related
- Groups one year ahead of normal grade increase more rapidly in both weight and height than normal groups of the same age, with one exception — related
- Pupils designated accelerated by their teachers, or selected by age-grade criteria, score above grade standards on the alertness tests — related
- Physiological age, as evidenced by the advent of pubescence or first menstruation, shows wide variations and low correlations with other traits — reports the opposite
- Anatomical development measured by wrist-bone radiographs correlates very highly with height and weight in the Baldwin study — related
- Town's intensive study gave 52 first-year school children unusually thorough physical, anthropometric and mental measurement — related
- Mental growth curves of superior children diverge from those of average children and resemble physical growth curves — a broader claim this one bears on
