Subclaims¶

q3 i? VGPs and NVGPs showed equivalent accuracy while VGPs responded substantially faster (p-eta2 = .47), and the group factor interacted with motion coherence (p-eta2 = .15), with greater RT decreases at low than high coherence. → Green 2010

Behavioral results of Experiment 1: accuracy did not differ between groups (p-eta2 = .01) but RT did (p-eta2 = .47), and the group × coherence interaction reached significance (p-eta2 = .15), with larger RT differences at low coherence. No standardized effect size beyond p-eta2 is printed.

"While VGPs and NVGPs demonstrated equivalent accuracy - p = .65, p-eta2 = .01 (top panel), VGPs responded substantially faster than NVGPs - F(1,21) = 18.9, p < .001, p-eta2 = .47 (bottom panel). Importantly, this factor interacted with motion coherence due to a greater decrease in RTs at low than high coherence – F(6, 126) = 3.5, p < .001, p-eta2 = .15"
