Dopamine receptor D4 (DRD4) gene modulates the influence of informational masking on speech recognition.

Neuropsychologia - 1 Jan 2015

Abstract excerpt

Listeners vary substantially in their ability to recognize speech in noisy environments. Here we examined the role of genetic variation on individual differences in speech recognition in various noise backgrounds. Background noise typically varies in the levels of energetic masking (EM) and informational masking (IM) imposed on target speech. Relative to EM, release from IM is hypothesized to place greater demand...
