Table 1 HbT response mean values averaged across the 21 subjects within the time window from 2s to 18s and p-values indicating statistical significance of the difference between the response and baseline, evaluated using two-tailed Student’s t test for cluster C1 which shows a statistically significant negative mean speech response averaged across the conditions, for cluster C2 which shows a significant negative response to neutral speech.
