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? Included studies of technical skill performance indicate experts and novices show distinct brain activation patterns, with experts showing significantly lower activation, especially in the PFC, than novices. → Toy 2022
q2 i? One study with a longitudinal component found novices showed persistent PFC engagement even after demonstrating expert-level performance on observational measures. → Toy 2022 (2)

q2 · i? · review · r2
The review's thematic synthesis of included technical-skill neuroimaging studies, most of which were non-experimental. It reports that "Experts show significantly lower activation, especially in the PFC, than do novices", with no effect size printed.
"Overall, included research studies that used functional neuroimaging technology during technical skill performance indicated that experts and novices show distinct brain activation patterns. Experts show significantly lower activation, especially in the PFC, than do novices."

q2 · i? · review · r2
The review attributes this single longitudinal-component finding to reference [51]; the review reports it as a hint that demonstrated competency in a controlled educational environment may not necessarily translate into complex clinical settings.
"One study with a longitudinal component found that after repeated practice, novices still showed persistent engagement in the PFC even after they demonstrated expert level performance based on observational measures [51]."
