Listening is the primary gateway for children to learn in the mainstream classroom, but the dynamics and noise of modern classrooms can make listening challenging. This is especially true for children with hearing loss, language and communication difficulties, attention deficits, autism, other learning needs, and/or those communicating in a languag...

Objective: This study examined (1) the utility of a clinical system to record acoustic change complex (ACC, an event-related potential recorded by electroencephalography) for assessing speech discrimination in infants, and (2) the relationship between ACC and functional performance in real life. Methods: Participants included 115 infants (43 nor...

Background: Despite hearing aids adequately compensate for hearing loss, a substantial proportion of the population leave their hearing difficulties untreated. Even though this is a well-known clinical issue, the optimal approach to address this issue during the hearing rehabilitation process is still unclear. Purpose: The present study aims to cha...

Objective Examine the effect of language experience on auditory evoked and oscillatory brain responses to lexical tone in passive (ACC) and active (P300) listening conditions. Design Language experience was evaluated using two groups, Mandarin- vs. English-listeners (with vs. without lexical tone experience). Two Mandarin lexical tones with pitch...

All audiovisual translation (AVT) modes mediate the audiovisual text for the audience. For audiences excluded from all or part of a visual or an auditory channel, this has significant implications in terms of comprehension and enjoyment. With subtitling (SDH in particular), we want the audiences to have the same quality of access to the characters...

Objective: The current research investigated whether professional musicians outperformed non-musicians on auditory processing and speech-in-noise perception as assessed using behavioural and electrophysiological tasks. Design: Spectro-temporal processing skills were assessed using a psychoacoustic test battery. Speech-in-noise perception was mea...

Listening to speech in noise is effortful, particularly for people with hearing impairment. While it is known that effort is related to a complex interplay between bottom-up and top-down processes, the cognitive and neurophysiological mechanisms contributing to effortful listening remain unknown. Therefore, a reliable physiological measure to asses...

Objectives: Objective: Statistical learning (SL) is an implicit ability to extract statistical cues from continuous stream of stimuli. This study compared behavioural and online (electrophysiological) measures of SL in children with and without musical training. Material and methods: SL of regularities embedded in auditory and visual stimuli was me...

Objective The question whether musical training is associated with enhanced auditory and cognitive abilities in children is of considerable interest. In the present study, we compared children with music training versus those without music training across a range of auditory and cognitive measures, including the ability to detect implicitly statist...

Musicians’ brains are considered to be a functional model of neuroplasticity due to the structural and functional changes associated with long-term musical training. In this study, we examined implicit extraction of statistical regularities from a continuous stream of stimuli—statistical learning (SL). We investigated whether long-term musical trai...

This chapter presents the findings of a study to investigate the impact of subtitles on the processing of audiovisual texts in terms of levels of self-reported engagement with the text. It also presents a methodology for investigating the neural processing of subtitles using electroencephalography (EEG) and psychometrics. By establishing the beta c...

Listening to degraded speech can be challenging and requires a continuous investment of cognitive resources, which is more challenging for those with hearing loss. However, while alpha power (8–12 Hz) and pupil dilation have been suggested as objective correlates of listening effort, it is not clear whether they assess the same cognitive processes...

Subjective tinnitus is characterised by the conscious perception of a phantom sound. Previous studies have shown that individuals with chronic tinnitus have disrupted sound-evoked cortical tonotopic maps, time-shifted evoked auditory responses, and altered oscillatory cortical activity. The main objectives of this study were to: (i) compare sound-e...

We investigated if long-term musical training is associated with facilitation of extraction of distributional cues in an online auditory statistical learning (ASL) and visual statistical learning (VSL) task. Participants were seventeen musicians and eighteen age-matched non-musicians. Event related potentials were recorded as participants listened...

Objectives: Musicians’ brains are considered as a functional model of neuroplasticity due to the structural and functional changes associated with long term musical training. Statistical learning is an implicit ability to extract distributional cues from continuous stream of stimuli. This study investigated if long term musical training is associat...

Objectives: Deficits in auditory attention switching have been identified as a potential underlying problem in some individuals who struggle with speech perception in the presence of noise. The purpose of this study was therefore to investigate the underlying markers of this skill using adult participants. It is hoped that by developing a greater u...
