one outlier was discovered at 3 standardized residuals from the regression line describing the relation between the CCT and IFDC comprehension at 16 months. This parent had reported that the child knew all of the words on the IFDC but this was not consistent with the child’s performance on the CCT. With this outlier removed, the correlation between the CCT and the IFDC at each wave is significant consistent with previous reports (r(59)=.355, p=.006, and r(59)=.405, p=.001, respectively).
