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 N170 peak occurred later in children than adults, and this group difference interacted with letter condition; adults showed a later peak latency for reversed than normal letters, children did not. → Blackburne LK 2014

q3 · i? · causal · r1
Peak latency analysis of the ERP letter reversal task (12 adults, 12 children), measured between 125 and 250 ms on negative-going peaks. The group main effect (F(1,22) = 36.25, p <.001), the condition x group interaction (F(1,22) = 6.31, p = .02), and the adult condition effect (F(1,11) = 16.01, p = .002) were all significant; children's conditions did not differ (all Fs <1.1). No standardized effect size is reported here.
"The peak of the N170 occurred later in the children than in the adults (main effect of group: F(1,22) = 36.25, p ,.001, gp2 = .62). This group difference interacted with whether or not the letters were reversed or normal (condition x group interaction: F(1,22) = 6.31, p = .02, gp2 = .22). Examining each group individually revealed that adults showed significant differences in the peak latency of reversed compared to normal letters (main effect of condition: F(1,11) = 16.01, p = .002, gp2 = .6)"
