Fig. 5: The effect of temporal continuity on psychological and EEG responses during change detection task.
From: EEG neural indicator of temporal integration in the human auditory brain with clinical implications
a Experimental setup with two stimulus sets: the transitional train (No-gap) with varying contrasts (Experiment 3: Reg4-4, Reg4-4.01, Reg4-4.02, Reg4-4.03, Reg4-4.06), and a similar set that includes a 600 ms gap between click trains (Experiment 4). Participants identified auditory changes by pressing designated buttons. b Boxplots show psychological functions of ratio of change detection (mean: central line; standard error: box edges; 10th-90th percentiles: whiskers) for No-gap (red) and Gap (blue) tasks. Transparent dots represent individual participants (n = 34). c Scatterplots of behavioral thresholds in the two behavioral conditions (p < 0.001, two-tailed paired t-test). d Grand-averaged change responses to different ICI contrast at POz in No-gap condition. Shaded areas represent \(\pm\) SEM. e Grand-averaged responses at POz time-locked to the onset of the second sound under different stimuli in Gap condition. f Boxplots show the average P1/cP1 response as a function of ICI contrast for change responses (mean: central line; standard error: box edges; 10th−90th percentiles: whiskers) under No-gap (cP1 response, red) and Gap (P1 response, blue) conditions. Transparent dots represent individual participants. g The average N2/cN2 response as a function of ICI contrast under the two conditions.
