Auditory responses are modulated by acoustic–phonetic aptitude when listening to Dutch-accented speech only. Unless mentioned otherwise, details are as in Figure 6. A, Because predictive power at no sensor was meaningfully related to the LLAMA score (all t < 2), the scatterplot shows data for the average of all sensors. B, Consistent with results from predictive power, TRFs were not significantly modulated by phonetic ability. Line plots show predictions for LLAMA_D scores of 10 and 50. C, In brain responses to Dutch-accented speech, increased phonetic ability was associated with smaller predictive power of auditory predictors, that is, with weaker auditory responses. D, TRFs related to sustained auditory representations of Dutch-accented speech were modulated by aptitude at relatively late lags (224–277 ms).
