Grand-averaged transient evoked fields measured from the left and right hemisphere and the amplitudes and latencies of the N1m and P2m responses. The distorted sentences elicited N1m responses with a larger amplitude and an earlier peak latency than their undistorted counterparts. The N1m responses peaked later in the left hemisphere than in the right. The P2m responses were more prominent and occurred earlier for the distorted sentences than for their undistorted counterparts. Furthermore, the P2m latency and amplitude effects were more pronounced in the right hemisphere. The AEFs are from the sensor exhibiting maximum response, and the amplitude and latency results have been calculated from the vector sum from the sensor pair with the maximum response. Error bars indicate the standard error of the mean (SEM).
