Larger studies needed
Commenting on the findings for this news organization, Terrie E. Moffitt, PhD, professor of psychology, Duke University, Durham, N.C., noted that there is “general consensus among brain-imaging researchers that testing brain-behavior relations requires very large samples in the thousands and also samples of research participants who represent the full extent of variation in the population as well as possible – from rich to poor, from well to unwell, from high IQ to low IQ, from strong mental health to mental illness, etc.
“It would be grand to see this study’s provocative finding replicated in a large, representative sampling design,” Dr. Moffitt said.
The study was supported in part by the National Institutes of Health. Dr. Choy, Dr. Raine, and Dr. Moffitt have disclosed no relevant financial relationships.
