 note = {The present study investigated (1) the vowel merger of [I] and [ε] before the nasal [n] and (2) a recent rotation pattern of the vowel [I] using young and old Norfolk residents in Virginia. It was found that the vowel merger is still considered to be an important dialect marker even among young people. In addition, the target vowel [I] produced by the young subjects in general moved farther backward in the F2 dimension, which contradicts the rotation pattern of the Southern Vowel Shift (Labov, 1996,1997). Based on the present and Todaka's (2000,2001) studies, it is speculated that the backward movement of the vowel [I] might be accounted for by the principle of sufficient perceptual separation.},
