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.
q3 i? Higher fit children (>70th percentile VO2max) showed decreased gray matter thickness in superior frontal cortex, superior temporal areas, and lateral occipital cortex compared to lower fit children (<30th percentile VO2max). → Chaddock-Heyman L 2015

q3 · i? · associational · r1
Cross-sectional MRI study of 48 children (24 higher fit, 24 lower fit) screened for IQ, ADHD, pubertal timing, and SES. MANOVA on FreeSurfer-derived cortical thickness in a priori regions of interest showed "a significant effect of aerobic fitness on cortical thickness (F (22, 27) = 2.41, p = 0.017)".
"The overall multivariate test indicated a significant effect of aerobic fitness on cortical thickness (F (22, 27) = 2.41, p = 0.017)."
Discussion¶
Learner Variables¶
- Physical Well-Being — predictor: learners who differ on it differ in outcomes
Related Claims¶
- The authors propose aerobic fitness as a possible predictor of developmental cortical thinning and a pathway to enhanced cognition and scholastic performance — a broader claim this one bears on
- Aerobic fitness group differences in cortical thickness are regionally specific, absent in middle frontal, middle temporal, and parietal areas — related
- The brain regions showing fitness-related thinning overlap with regions undergoing typical developmental cortical thinning between ages 5 and 11 — related
- Cortical thinning in anterior and superior frontal cortex is associated with better arithmetic achievement across all children — related
- Higher fit children show superior mathematics achievement but no reading or spelling advantage over lower fit children — related
- The authors hypothesize that brain-reading cortical thickness correlations are positive in early reading acquisition and negative at later, consolidated stages — related
- SES moderates the brain-behavior relationship in children's arithmetic, with higher and lower SES children engaging different neurocognitive systems — related
