Subclaims¶

q3 i? In the EEG digit task, mnemonic-trained children showed significantly higher post-training discriminability (d') than pre-training, while the no-contact control group showed no session difference. → Yafeng Pan 2023

q3 · i? · causal · r1

A two-way ANOVA (Group: MT vs NC; Session: pre vs post) on EEG-task discriminability revealed only a significant Group × Session interaction, with MT post-training d' (2.10 ± 0.19) higher than pre-training (1.37 ± 0.12); "there was no signi ficant difference between the pre-training phase (1.12 ± 0.15) and the post-training phase (1.16 ± 0.10) in the NC group".

"It revealed the signi ficance only for the Group × Session interaction, F (1, 31) = 15.46, p < 0.001, η2 partial = 0.30. Upon further analysis, it was found that post-training discriminability"
