title: Genetic factors and neurocognitive traits.
abstract: Genetic contributions to phenotypic variation in general intelligence have been studied extensively. Less research has been conducted on genetic contributions to specific cognitive abilities, such as attention, memory, working memory, language, and motor functions. However, the existing data indicate a significant role of genetic factors in these abilities. Stages of information processing, such as sensory gating, early sensory registration, and cognitive analysis, also show evidence of genetic contributions. Recent molecular studies have begun to identify candidate genes for specific cognitive functions. Future research, identifying endophenotypes based on cognitive profiles of neuropsychiatric disorders, may also assist in the detection of genes that increase susceptibility to major psychiatric disorders.
