Phase-locking value (PLV) for /da/ (younger vs. older) (A) and PLV for /a/ (younger vs. older) (B). The black color signifies that the responses of the younger and older adults are significant in phase (values ≥ 0.95), while the white color signifies that the responses of the two groups are out of phase (values < 0.95). The threshold value of 0.95 has been chosen based on the parameters used to calculate the PLV.
