Table 4.
Positive (+) and negative (-) age and accuracy correlations for the lexical conditions versus null and the O+P- (conflicting non-rhyming) versus O-P- (non-conflicting non-rhyming) conditions, excluding overlap of activation with the perceptual versus null contrast. RT+ Age+ rows correspond to activation positively associated with reaction time within subjects (RT+) that increases as a function of age (Age +) between subjects.

Note. H = hemisphere, L = left, R = right, BA = Brodmann Area G = gyrus. Activation is presented with p < 0.001 uncorrected. x, y, z: Montreal Neurological Institute (MNI) coordinates listed only for clusters with volume greater than 15 voxels. All coordinates listed correspond to effect maxima.
