Subclaims¶

q3 i? Cluster-based validation found no significant pre-post ERP differences; the only oscillatory difference was increased alpha power (18 ± 2% vs 6 ± 3%), which did not correlate with memory increment (r = 0.23, p = 0.57). → Yafeng Pan 2023

q3 · i? · causal · r1

Two cluster-based validation analyses in the MT group tested for generally decreased neural activity: ERP validation found nothing surviving correction, and oscillatory validation found increased alpha power at 1000–1400 ms (post 18 ± 2% vs pre 6 ± 3%, pcorr < 0.05) that "failed to signi ficantly correlate with memory increment, r = 0.23, p = 0.57".

"With ERP validation, no signi ficant results survived after the cluster-based correction. However, with oscillatory power validation, we found a signi ficant power difference between pre- and post-training sessions in the window of 1000 –1400 ms"
