Processing speed is an important human cognitive capability that might underlie differences in other cognitive skills and their aging. We aimed to test aging-related processing speed differences using a novel cross-sectional design that adj...
Examining non-syndromic autosomal recessive intellectual disability (NS-ARID) genes for an enriched association with intelligence differences [0.03%]
对非综合性的常染色体隐性遗传的智能不足（NS-ARID）基因与智力差异的相关性进行丰富性检验
W D Hill,G Davies,D C Liewald et al.
W D Hill et al.
Two themes are emerging regarding the molecular genetic aetiology of intelligence. The first is that intelligence is influenced by many variants and those that are tagged by common single nucleotide polymorphisms account for around 30% of t...
