Article Synopsis
- Right-ear advantage is the phenomenon where listeners more accurately identify speech sounds presented to the right ear compared to the left due to the predominance of the left auditory cortex in processing speech.
- This study used magnetoencephalography to examine how attention affects this advantage while participants listened to pairs of Japanese words presented separately to each ear with varying frequencies.
- Results showed that exercises requiring attention enhanced the auditory response amplitude, reinforcing the connection between attention allocation and the right-ear advantage, as well as demonstrating increased neural activity in the left auditory cortex.
Difficulty in listening comprehension is a major audiological complaint of older adults. Behavioural auditory processing tests (APTs) may evaluate it. The aim was to assess the feasibility of administering Japanese APTs to older adults at otolaryngology clinics.

Objectives: Speech perception abilities, which vary widely among cochlear implant (CI) users, are considered to be associated with the integrity of the central auditory pathways from the auditory nerve to the cortex. Therefore, auditory evoked potentials (AEPs) are used to evaluate central auditory processing, which is thought to contribute to speech perception in CI subjects. In AEPs, the P300 component reflects the cognitive ability of subjects to detect and respond to stimuli and has most frequently been used and investigated in CI subjects.
