Figure 5.
Relationship between voice-onset time and multisensory integration. A, B, Median (black lines) and interquartile ranges (gray boxes) of enhancement and suppression relative to voice-onset time. The x-axis represents voice-onset time; the y-axis represents the log10-base percentage of the multisensory integration index value. gt, Grunts; co, coos. Note that in A, there was only one enhancement response in the “256 ms/gt” category, whereas in B, there was no response in the “85 ms/co” category and only one response in the “97 ms/gt” category. The magnitude of multisensory effects was not related to voice-onset time. C, D, Proportion of enhanced (n = 93) and suppressed (n = 40) responses across the different voice-onset time categories. Note that enhancement was more frequently observed for short voice-onset times, whereas suppression was more common at longer voice-onset times.
