Development of auditory processing in 6- to 11-yr-old children.

Objectives: The aim of this study is to provide developmental standards on a variety of temporal, spectral, and binaural psychoacoustic (auditory processing [AP]) tests in typically developing children, including immediate and delayed retest reliability, and comparisons between single listener performance on different tests. This study also informs choices on the selection of tests for clinical evaluation of hearing and listening (e.g.

Nature of auditory processing disorder in children.

Objective: We tested the specific hypothesis that the presentation of auditory processing disorder (APD) is related to a sensory processing deficit.

Methods: Randomly chosen, 6- to 11-year-old children with normal hearing (N = 1469) were tested in schools in 4 regional centers across the United Kingdom. Caregivers completed questionnaires regarding their participating children's listening and communication skills.

Planar localisation analyses: a novel application of a centre of mass approach.

Sound localisation is one of the key roles for listening, and measuring localisation performance is a mainstay of the hearing research laboratory. Such measurements may consider both accuracy and, for incorrect trials, the size of the error. In terms of error analysis, localisation studies have frequently used general purpose univariate techniques in conjunction with either mean signed or unsigned error measurements.

Attention in neglect and extinction: assessing the degree of correspondence between visual and auditory impairments using matched tasks.

Claims have been made for associated degrees of impairment on both visual and auditory performance in unilateral neglect and extinction. Since this evidence is primarily based on different tests in each modality, it is difficult to properly quantify the degree of association between performance in vision and audition. The current study compares visual and auditory extinction and temporal order judgments (TOJs) in two cases with clinical visual neglect.

Frequency discrimination learning in children.

Psychoacoustic thresholds of pure tone frequency discrimination (FD) in children are elevated relative to those of adults. It has been shown that it is possible to improve FD thresholds in adults, following a single (subhour) training session. To determine whether FD thresholds in children may be improved by training and, consequently, reduced to adult levels, 100 normally hearing 6- to 11-year-old children and adults received approximately 1 h of training on a FD task at 1 kHz.
