Conversational Dynamics in Task Dialogue Between Interlocutors With and Without Hearing Impairment.

This study investigated the effects of noise and hearing impairment on conversational dynamics between pairs of young normal-hearing and older hearing-impaired interlocutors. Twelve pairs of normal-hearing and hearing-impaired individuals completed a spot-the-difference task in quiet and in three levels of multitalker babble. To achieve the rapid response timing of turn taking that has been observed in normal conversations, people must simultaneously comprehend incoming speech, plan a response, and predict when their partners will end their turn.

Copresence Was Found to Be Related to Some Pupil Measures in Persons With Hearing Loss While They Performed a Speech-in-Noise Task.

Objectives: To assess if a manipulation of copresence was related to speech-in-noise task performance, arousal, and effort of persons with hearing loss. Task-related arousal and effort were measured by means of pupillometry.

Design: Twenty-nine participants (mean age: 64.

Alpha Oscillations During Effortful Continuous Speech: From Scalp EEG to Ear-EEG.

Objective: The purpose of this study was to investigate alpha power as an objective measure of effortful listening in continuous speech with scalp and ear-EEG.

Methods: Scalp and ear-EEG were recorded simultaneously during presentation of a 33-s news clip in the presence of 16-talker babble noise. Four different signal-to-noise ratios (SNRs) were used to manipulate task demand.

Social observation increases the cardiovascular response of hearing-impaired listeners during a speech reception task.

Certain cardiovascular measures allow for distinction between sympathetic and parasympathetic nervous system activity. Applied during listening, these measures may provide a novel and complementary insight into listening effort. To date, few studies have implemented cardiovascular measures of listening effort and seldom have these included hearing-impaired participants.
