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? Neuroimaging evidence indicates brain maturation takes more than twenty years, with executive-function circuitry among the last areas to fully develop, so children and adolescents hold less interest in the future than their adult selves. → Adam M. Lavecchia 2014

q2 · i? · review · r2
The review reports, citing neuroimaging studies, that brain maturation "takes more than twenty years, with the circuitry responsible for executive function being among the very last areas to fully develop". No effect size is printed; the finding is a narrative synthesis of neuroscience literature.
"Neuroimaging studies have demonstrated otherwise: maturation takes more than twenty years, with the circuitry responsible for executive function being among the very last areas to fully develop."
