Willerman et al. (1991) collected a sample of 40 right-handed Anglo introductory psychology students at a large southwestern university. Subjects took foursubtests (Vocabulary, Similarities, Block Design, and Picture Completion) of the Wechsler Adult Intelligence Scale-Revised (1981). The researchers usedMagnetic Resonance Imaging (MRI) to determine the brain size of the subjects. The research hypothesis was that brain size is correlated with IQ.
