q3 i2 During the first learning module, N250 amplitude was significantly more negative in both the 3D and 2D/3D groups compared to the 2D group in all blocks. → Anderson 2019

q3 · i2 · causal · r2

EEG experiment with health sciences students (n=61) randomized to 2D, 3D, or combined 2D/3D learning of cross-sectional neuroanatomy. RM-ANOVA on N250 amplitude at O1 showed a group effect, "F(2, 150) = 10.96, p < 0.001, η2 = 0.13", with 3D and 2D/3D more negative than 2D in all blocks.

"However, there was a signi ficant difference among groups for N250 amplitude, F(2, 150) = 10.96, p < 0.001, η2 = 0.13. Specifically, the N250 amplitude was signi ficantly more negative (p < 0.05) in both the 3D and 2D/3D groups compared to the 2D group in all blocks."
