    Complex variation in measures of general intelligence and cognitive change. by Suzanne J Rowe, Amy Rowlatt, Gail Davies, Sarah E Harris, David J Porteous, David C Liewald, Geraldine McNeill, John M Starr, Ian J Deary, Albert Tenesa

    Published 2013-01-01
    “…Measures of crystallised (gc) and fluid intelligence (gf) in late adulthood (64-79 years) were available for 1806 individuals genotyped for 549,692 autosomal single nucleotide polymorphisms (SNPs). The same individuals were tested at age 11, enabling us the rare opportunity to measure cognitive change across most of their lifespan. 547,750 SNPs ranked by position are divided into 10, 908 overlapping regions of 101 SNPs to estimate the genetic variance each region explains, an approach that resembles classical linkage methods. …”
