q3 i? The rate parameter β of accuracy growth was higher in VGPs for both visual motion (p-eta2 = .19) and auditory tone (p-eta2 = .18) tasks. → Green 2010

q3 · i? · causal · r1

Critical duration study (Experiment 4): stimuli shown for fixed durations, accuracy modeled as exponential rise. The article reports higher β in VGPs in both modalities (p-eta2 = .19 visual; p-eta2 = .18 auditory); simulations showed equal-sensitivity models could not capture the faster rise for VGPs.

"This prediction was confirmed (visual motion: VGP: 8.1 +/− 1.1, NVGP: 4.8 +/− 1.1 - F(1,21) = 4.6, p = .045, p-eta2 = .19; auditory tone: VGP: 24.5 +/− 3.9, NVGP: 12.9 +/− 3.8 - F(1,21) = 4.5, p = .044, p-eta2 = .18)"
