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 i? In participants aged 6 to 20 years, structural maturation and brain activity indices predicted cognitive performance two years later better than cognitive measures closely tied to past learning. → Arsalidou 2016
Evidence¶
Arsalidou 2016¶
Arsalidou, M. & Pascual-Leone, J. (2016). Constructivist developmental theory is needed in developmental neuroscience. npj Science of Learning 1, 16016. https://doi.org/10.1038/npjscilearn.2016.16
q2 · i? · review · r2
The review reports, citing the study, that predictive regions were associated with the basal ganglia and thalamus rather than typical attentional-network prefrontal and parietal areas. No effect size is printed.
"A study of participants aged 6 to 20 years shows that (compared with cognitive measures closely tied to past learning) the indices of structural maturation and brain activity are better able to predict cognitive performance 2 years later"
