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? At all delayed time points, the speech-then-gesture and speech-then-speech conditions did not differ significantly on basic or generalization problems. → Congdon Eliza L. 2017

q3 · i? · causal · r2

Across next-day and four-week follow-ups in the three-condition experiment, the two sequential conditions never differed significantly (e.g., basic problems next day: β = 0.50, p = .80), indicating simultaneity rather than mere modality split produced the benefit.

"The lack of significant differences between the S S and the S G conditions suggests that using multiple modalities per se is not likely to be driving the benefits observed in the S G training condition."
