Subclaims¶

q3 i? FFT spectra of detrended RTs showed no significant peak at the corresponding stimulation frequency for either stimulation condition, irrespective of congruency. → Zhijun Liao 2024

q3 · i? · causal · r2

FFT on detrended, Hanning-tapered RT time series sorted by SOA, tested against 5000 shuffled surrogate datasets with FDR correction at q < 0.05; "neither stimulation induced a signi ficant spectral peak" at its stimulation frequency. Non-significant result with no printed effect size.

"Unexpectedly, neither stimulation induced a signi ficant spectral peak at the corresponding frequency, irrespective of the congruency (Fig.1c; tested via 5000 times permutation wi th FDR correction at q < 0.05)."

Discussion¶

Related Claims¶

• Alpha-rate (10 Hz) but not theta-rate (5 Hz) sensory stimulation improves accuracy of speech-print associative learning compared to a null-stimulation control — related
• 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
