Table 4.

Details regarding statistically significant activation in cortical areas during the Auditory phase of the sentence verification task that correspond to the following statistical tests: (a) interaction of difficulty × length, (b) post hoc analysis of difficulty greater than length, (c) post hoc analysis of length greater than difficulty, (d) interaction of group × length, and (e) post hoc analysis, full terms greater than preterms. Cluster size > 10 contiguous voxels. Statistical significance for interactions set at p < 0.05 FWE correction for multiple comparisons; significance level for post hoc analyses set at p < 0.01 uncorrected.
