Subclaims¶

q3 i3 In Experiment 2, the integration rate parameter was significantly greater in VGPs (Cohen's d = 1.66), the decision bound significantly smaller, and log odds were 48% higher in VGPs across SNR levels. → Green 2010

DDM fits to the auditory analog task (tone in white noise, varying tone-to-noise amplitude ratio). The article reports integration rate greater in VGPs with Cohen’s d = 1.66, and also log odds "48% higher on average across all levels of signal to noise ratio in VGPs" and a 51% increase in feed-forward connection strength in the neural model.

"The rate of integration was greater in the VGP than the NVGP group - t(21) = 3.8, p = .001, Cohen’s d = 1.66 (top panel), while the opposite result was observed for the decision bound - t(21) = 2.6, p = .02, Cohen’s d = 1.13 (middle panel)"
