q3 i3 In the DDM fit to Experiment 1, the rate of integration was greater in VGPs than NVGPs (Cohen's d = 1.13), with no difference in non-decision time. → Green 2010

Green, C.S., Pouget, A., & Bavelier, D. (2010). Improved probabilistic inference as a general learning mechanism with action video games. Current Biology. https://doi.org/10.1016/j.cub.2010.07.040

q3 · i3 · causal · r?

Drift diffusion model fits to individual subjects' RT and accuracy data in Experiment 1 (coherent dot motion). The article reports "the rate of integration was greater in the VGP than the NVGP group" with Cohen’s d = 1.13; decision bound was lower in VGPs (d = 1.57) and non-decision time did not differ (d = 0.14).

"The rate of integration was greater in the VGP than the NVGP group (t(21) = 2.6, p = .02, Cohen’s d = 1.13, top panel), while the opposite result was observed for the decision bound"
