Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q3 i3 In the second module, reward positivity amplitude was significantly decreased in the 2D/3D group compared to the other groups in all blocks, while 2D and 3D groups did not differ. → Anderson 2019

In the second module (~30 days after the first), all participants completed an identical 2D/3D task. RM-ANOVA showed a group effect, "F(2, 168) = 13.40, p = < 0.001, η2 = 0.14": the interleaved 2D/3D group had significantly decreased reward positivity in all blocks versus both other groups.
"There was also a signi ficant difference among groups for amplitude of reward positivity in the second module, F(2, 168) = 13.40, p = < 0.001, η2 = 0.14. Specifically, the amplitude of reward positivity was signi ficantly decreased in the 2D/3D groups compared to the other groups in all blocks ( p < 0.05), and the reward positivity amplitudes did not differ from each other in the 2D and 3D groups ( p > 0.05)."
Discussion¶
Related Claims¶
- Learning anatomy from stereoscopic 3D models yields greater object recognition (N250 amplitude) than learning from 2D models — related
- Behavioral accuracy improved strongly over blocks but did not significantly differ among the 2D, 3D, and 2D/3D learning groups despite neural differences — related
- During initial learning, the interleaved 2D/3D group showed reduced reward positivity from block 2 onward, diverging from both the 2D and 3D groups — related
- Reward positivity showed no forgetting-curve lapse after ~30 days despite a lapse in behavioral accuracy, indicating retained ability to internally evaluate responses — related
