Joanne Ruthsatz, PhD, from The Ohio State University in Columbus, and Jourdan B. Urbach, from Yale University in New Haven, Conn., took the developmental histories of eight child prodigies (in art, math, music, and gastronomy) and tested them for intelligence (via the Stanford-Binet 5th ed. full scale) and autistic traits (via the Autism-Spectrum Quotient).The researchers found that three prodigies were diagnosed with autism spectrum disorders and four had first- or second-degree relatives with the disorder. The prodigies showed a general elevation in autistic traits compared with a control group, but less so than in individuals with high functioning autism or Asperger's syndrome. All had elevated scores with respect to attention to detail. While they all showed a modestly elevated level of general intelligence, their working memory scores were all in the 99th percentile.
