Subclaims¶

q3 i2 Reward positivity was similar across groups in block 1, but the 2D/3D condition differed significantly from both 2D and 3D in blocks 2–3 and from 2D in blocks 4–5. → Anderson 2019

Module 1 EEG analysis of reward positivity to positive feedback across five blocks. RM-ANOVA group effect "F(2, 54) = 5.89, p = 0.003, η2 = 0.07"; the interleaved group diverged from the 2D and 3D groups from block 2 onward.

"Interestingly, there was a signi ficant difference in reward positivity among groups, F(2, 54) = 5.89, p = 0.003, η2 = 0.07. Reward positivity was similar across all groups in the first block ( p > 0.05), however reward positivity in the 2D/3D condition was significantly different from both the 2D and 3D conditions in blocks 2 and 3, and from the 2D condition in blocks 4 and 5 ( p < 0.05)."
