Previous research has suggested a relationship between auditory evoked potentials (AEPs) and spoken language proficiency, but their interactions during the earliest stages of development are not well understood. AEP-Age, an index that estimates the maturity of a child’s AEP relative to same-aged peers, has been effective in investigating this relationship in school-aged children, but has yet to be applied to younger populations. This thesis includes two Stage 1 Manuscripts (Registered Reports) for future studies to (a) assess the utility of AEP-Age to predict chronological age and language ability in 18-48-month-old children, and (b) investigate the relationship between AEP-Age and …

Twenty-four participants, consisting of six sibling pairs and six non-sibling pairs, participated in this study investigating the familiality of auditory evoked potentials (AEPs). The auditory brainstem response (ABR) recorded at high stimulus rates, revealed that Wave V latency increases, while amplitude decreases as stimulus rate increases. ABR Wave V latency was also found to increase with click position within a stimulus train, plateauing by the third stimulus. No evidence for familiality was found with respect to the ABR Wave V under these conditions. The late latency response (LLR) components N1 and P2 were found to decrease between the first and …
