Stromswold: Genetics of Language
Stromswold: Genetics of Language: " One of the central issues in cognition today is the degree to which cognitive abilities such as language are the result of specialized, genetically-encoded structures and predispositions (e.g., Pinker, 1994, 1997).
In order to determine the extent to which genetic and environmental factors play a role in normal language and language disorders, we have conducted comprehensive reviews and meta-analyses of over 80 existing family aggregation studies, pedigree studies, sex-ratio studies, linkage studies, quantitative trait loci studies, twin studies and adoption studies which investigate the heritability of language.
These meta-analyses reveal that heritable factors play a strong role in SLI and dyslexia, and in normal spoken and written language (Stromswold, 1998, 2001). These analyses also suggest some of these heritable factors are specific to linguistic tasks (Stromswold, 2001)."
