The article by Venables and Raine in this issue of the Journal (1) is the latest report from the Mauritius Child Health Project, a remarkable ongoing three-generation cohort study (2). During the study, neuropsychological assessments were conducted on the middle, or “G2,” generation at multiple time points from age 3 to age 40. When those in this middle generation were children, malnourishment was still common in Mauritius. The article by Venables and Raine analyzes data from participants ranging from 3 to 23 years old in this middle generation.
