Stimuli and experimental design. A; examples of the black/white (left) and red/green (right) stimuli are displayed. B: spectrogram of the auditory stimulus, termed CHirp-spEECH “Cheech,” is shown for 1 of the sentences (left), and a zoomed-in view of a chirp train is illustrated (right) to demonstrate that the 2nd chirp in each train was omitted for recording a clear auditory middle latency response. C: overview of the stimulus presentation is depicted.
