Subclaims¶

q3 i? NVGPs trained 50 hours on action or control games showed better use of the evidence at post-test only in the action group (log odds 16% higher on the motion task, 31% on the auditory task). → 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 · i? · causal · r?

Training study (Experiment 3): NVGPs underwent 50 hours of action or control video-game training. The article states the results were "nearly identical to the results of Experiments 1 and 2" and that better use of evidence was noted only in the action group; no effect size is printed.

"The log odds for the motion task were 16% (respectively 31% for auditory) higher on average across all levels of coherence (respectively SNR) at post-test as compared to pre-test for the action group"
