Demographic data for the study group of 55 healthy adults, both totals and separated by MRI acquisition at 1.5T vs. 3T field strength. SES: socioeconomic status, higher scores represent lower SES (range 11 – 77); handedness inventory: scores 14–32 right-handed, 50–70 left-handed. ANART: age-corrected IQ, American National Adult Reading Test. Note: MRI data were available from 51 of 55 participants.
