Effects of vocabulary and fluency in parietal regions
| Left inferior parietalx = −44, y = −54, z = 46 | Right inferior parietalx = 52, y = −52, z = 44 | |
|---|---|---|
| Vocabulary | 4.2 | 3.8 |
| Fluency | NS | NS |
| Vocabulary > alliteration fluency | 3.9 | 2.7 |
| Vocabulary > rhyme fluency | 2.2 | 2.7 |
| Vocabulary > mean fluency | 3.8 | 2.8 |
The data were generated from the first VBM analysis that involved multiple regression with seven regressors: (1) vocabulary, (2) alliteration fluency, (3) rhyme fluency, (4) verbal IQ, (5) performance IQ, (6) age, and (7) global signal intensity. Z scores associated with the vocabulary and fluency regressors and the comparisons between them are given at the peak coordinates for the main effect of vocabulary in the left (x = −44, y = −54, z = 46) and right (x = 52, y = −52, z = 44) inferior parietal regions. Note that the peak coordinates for these effects are within 5 mm of those reported by Mechelli et al. (2004) for second language acquisition. NS, Not significant.
