Regarding the interplay between OXTR genotypes and language processing, research on autism spectrum disorder has accumulated some evidence that autism-related difficulties in interpersonal information processing and in theory-of-mind (ToM) abilities – especially in those ToM abilities requiring language comprehension and higher-order cognitive and semantic understanding – can be positively influenced by intranasal/intravenous oxytocin applications (Hollander et al., 2007; Dadds et al., 2014). This evidence concerns the gene OXTR and autism spectrum disorder.
