q3 · i? · causal · r2

Home experiment with 66 participants learning 120 Dutch-German word pairs over four days, with 60 words cued nightly via mp3 during sleep. Cued words improved "163.42 ± 4.66%" vs 167.29 ± 5.61% for uncued, no significant difference (P > 0.25); equivalence was not tested.

"For cued words, participants increased their memory performance from day 1 to day 4 by 163.42 ± 4.66%, while uncued words improved by 167.29 ± 5.61%. We observed no significant difference in memory improvement between cued and uncued words ( P > 0.25)."
