Subclaims¶

q3 i? Alpha-rate (10 Hz) sensory entrainment significantly improved response accuracy in paired associative learning compared to the Null condition. → Zhijun Liao 2024 q3 i? Theta-rate (5 Hz) stimulation did not significantly modulate paired associative learning accuracy relative to the Null condition. → Zhijun Liao 2024 (2)

Evidence¶

Zhijun Liao 2024¶

Zhijun Liao, Xiya Ao, Yulu Sun, Manli Zhang & Xiangzhi Meng. (2024). Alpha sensory stimulation modulates theta phase during speech-print associative learning. npj Science of Learning. https://doi.org/10.1038/s41539-024-00263-5

q3 · i? · causal · r1

Between-subjects experiment: 36 Chinese undergraduates were randomly assigned to a 10 Hz tone-flash entrainment condition and performed the PAL task; independent-samples t-test against the Null control group showed "t41 = −2.39, p = 0.021" with mean accuracy 0.95 vs 0.91. Only a t statistic was printed, so no effect size is reported here.

"First, α-rate sensory entrainment (M ± SD = 0.95 ± 0.03; t41 = −2.39, p = 0.021) significantly improved the response accuracy compared to the Nullcondition [0.91 ± 0.06]"

q3 · i? · causal · r2

Same between-subjects PAL experiment: the 5 Hz theta stimulation group's accuracy (0.92 ± 0.08) did not differ from the Null condition, "t41 = 0.60, p = 0.595". A non-significant test with no printed effect size; equivalence was not tested.

"while θ-rate stimulation (0.92 ± 0.08;t41 = 0.60, p = 0.595) did not modulate the performance of associative learning (Fig. 1b)."

Discussion¶

Related Claims¶

• Alpha-rate stimulation resets the phase of RT fluctuations at ~4 Hz and ~7 Hz during early exposure to congruent speech-print pairs, an effect absent at late consolidation, in incongruent trials, and under theta-rate stimulation — related
• Neither alpha- nor theta-rate stimulation induced a significant behavioral spectral peak at its own stimulation frequency in detrended RT series — related
