Electrophysiological Evidence for Sentence Comprehension - Wings

of error detection as observable in a small or nonexistent difference between
experimental conditions in the SLI group; and (2) later latencies of characteristic peaks of
ERP components (if they could be identified at all in the SLI group given the -100 – 1000
ms window).
However, one more comparison should be made. The difference between the experiments
is very small in the group of children with SLI. Figure 71 shows violation condition in
both ‘tense-chi’ and ‘case-chi’ experiment for all electrodes. The similarity is especially
observable on the frontal and central electrodes where the dissociation of the syntactic
processing should have been most prominent (Figure 72).
