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? The terminal CNV was larger in old high performers relative to old middle and low performers, with no difference from middle-aged or young adults. → Patrick D. Gajewski 2020

q3 · i? · associational · r2
Cue-locked ERP analysis at FCz in the preparatory interval of the Stroop task. The CNV ANOVA showed a main effect of Group (ηp2 = 0.055) and post-hoc tests showed "a larger (more negative) CNV in OH relative to OM and OL performers" with no difference from younger groups, suggesting preserved proactive control.
"Bonferroni corrected post-hoc tests yielded a larger (more negative) CNV in OH relative to OM and OL performers (both p's < 0.05). No differences were found between old high and middle-aged or young adults (all p's > 0.05)."
