Objective: A literature review found that questionnaires for persons with problems of listening seeking assessment of auditory processing skills are not applicable for adolescents and adults. We developed a questionnaire designed for adolescents and adults seeking evaluation of problems with listening or following diagnosis to determine the subject's status.

Design: Following a model described by Del Zoppo, Sanchez, and Lind, a 34-item questionnaire was developed that investigates auditory processing abilities in six common areas of complaint in Auditory processing disorders (APD) (Keith, et al.

Background: To add to the limited body of literature on ocular vestibular evoked myogenic potential (oVEMP) responses in children and to assess a different montage for oVEMP recording.

Purpose: To evaluate the characteristics of the oVEMP response in children and compare the results with that of a group of healthy adults.

Research Design: Prospective descriptive study from a tertiary referral center.

Objective: In this study, different kinds of memory were evaluated using Rey Auditory Verbal Learning (RAVLT) test and were compared between two groups of typical and gifted students using Digit Span test. Finally, we determined if working memory interfered with scores in different Rey stages or not.

Material & Methods: This study was conducted in Tehran City, Iran in 2013.

Introduction: The purpose of the present study was to identify biomarkers of listening difficulties by investigating white matter microstructure in children suspected of auditory processing disorder (APD) using diffusion tensor imaging (DTI). Behavioral studies have suggested that impaired cognitive and/or attention abilities rather than a pure sensory processing deficit underlie listening difficulties and auditory processing disorder (APD) in children. However, the neural signature of listening difficulties has not been investigated.

Dichotic listening (DL) tests are among the most frequently included in batteries for the diagnosis of auditory processing disorders (APD) in children. A finding of atypical left ear advantage (LEA) for speech-related stimuli is often taken by clinical audiologists as an indicator for APD. However, the precise etiology of ear advantage in DL tests has been a source of debate for decades.

Objectives: The children with difficulty in receiving sounds presented at rapid rates in speech sounds and language learning period, may have delay in speech sounds and language development due to hearing speech sounds not clearly. Auditory temporal processing (ATP) is the ability to perceive auditory signals of brief duration accurately when presented at rapid rates. ATP can be evaluated by the random gap detection test (RGDT), which detects a brief gap between two stimuli.

Cantonese dichotic digits recognition was evaluated in free-recall, directed-attention right, and directed-attention left response conditions. All participants were right-handed and included a group of young adults with normal hearing and a group of older adults with minimal sensorineural hearing loss. In all conditions, performance by the young adults was better than performance by the older adults.

Objective: To examine the effects of solvent exposure on hearing function, through an audiological test battery, in a population not occupationally exposed to high levels of noise.

Methods: One hundred ten workers from a coating factory were studied. Jobs at the factory were divided into three different levels of solvent exposure.

Objectives: In auditory neuropathy (AN) children with hearing aids (HAs) or cochlear implant (CI), the speech perception improvement may not be in a significant degree. These children may perform speech perception after a few repeats. This condition may show that these children had difficulties in receiving and processing speech sounds.

Single and double dichotic digit tests in Malay language were developed and standardized as an initial attempt to incorporate tests of auditory processing within the scope of audiology practice in Malaysia. Normative data under free recall, directed right-ear first, and directed left-ear first listening conditions were determined using 120 Malay children between the ages of 6 and 11 years old with normal hearing and normal academic performance. Test-retest reliability was assessed in 15 of the study subjects.

Study Design: A case report is presented.

Objective: To report a previously undescribed complication related to use of a neurogenic motor-evoked potential monitoring electrode and electrosurgery during spinal surgery.

Summary Of Background Data: Although electrosurgery is one of the most commonly used technologies in the operating room, its electrophysical properties, including the potential for complications, are poorly understood by many surgeons.

Speech-language pathologists are often faced with the need to assess and treat the suspected auditory processing problems of children with language and learning difficulties. This article discusses central auditory processing disorders (CAPDs). Included are a discussion of background information, a current definition of CAPDs, a general discussion of test battery approaches following suggestions made by the American Speech-Language- Hearing Association (ASHA) Task Force on Central Auditory Processing Consensus Development (1996), and various approaches to intervention with persons identified as having a CAPD.
