Objective: Previous research has shown that dichotic listening training has improved auditory and language processing for individuals with large interaural asymmetries on dichotic listening tasks. This training can be a useful treatment for children with autism spectrum disorder (ASD).
Design: A single subject, multiple baseline across subjects study was utilized.
Study Sample: Three children with ASD, between the ages of 8-12, participated in the study.
Results: This training demonstrated improvement in language and auditory processing tasks following completion of up to twelve weeks of auditory training.
Conclusion: This study supports the idea that deficit specific, dichotic auditory training can remediate auditory and language deficits for children with ASD. More research is needed, with a group design and controls, in order to generalize these results to the larger ASD population.

Background: Patients with behavioural variant frontotemporal dementia (bvFTD) and right temporal variant frontotemporal dementia (rtvFTD) commonly exhibit abnormal hedonic and other behavioural responses to sounds, however hearing dysfunction in this disorder is poorly characterised. Here we addressed this issue using the Queen Square Tests of Auditory Cognition (QSTAC) - a neuropsychological battery for the systematic assessment of central auditory functions (including pitch pattern perception, environmental sound recognition, sound localisation and emotion processing) in cognitively impaired people.
Method: The QSTAC was administered to 12 patients with bvFTD, 7 patients with rtvFTD and 24 patients with comparator dementia syndromes (primary progressive aphasia and typical Alzheimer's disease) and 15 healthy age-matched individuals.

This study compares results from three dichotic listening experiments involving different methods of attention control. In each experiment, participants completed a dichotic listening task requiring two responses to syllables and we noted the order of report for the responses. In Experiment 1, participants reported from a specific ear first in trial blocks.

Objectives: Listening effort is moderated by not only task difficulty, but also success importance. In real communication scenarios, success importance varies based upon the social context. However, in the laboratory, it can be challenging to manipulate social context without compromising experimental control.

Binaural pitch fusion, the perceptual integration of dichotically presented stimuli that evoke different pitches, can be considered a type of simultaneous grouping. Hence, auditory streaming cues such as temporally flanking stimuli that promote sequential grouping might compete with simultaneous dichotic grouping to reduce binaural fusion. Here, we measured binaural pitch fusion using an auditory streaming task in normal-hearing listeners and hearing-impaired listeners with hearing aids and/or cochlear implants.

Prior work has suggested that visual working memory as measured in change detection tasks can be based on recollection, whereby participants consciously identify a specific feature of a stimulus that has changed, or on familiarity, whereby participants sense that a change has occurred but are unable to consciously access what has changed. Whether recollection and familiarity also contribute to auditory working memory is unclear. The present study aims to address that gap in knowledge by having participants make confidence judgments in change detection tests for speech sounds and pure tones.
