A double-blind, placebo-controlled study examined effects of methylphenidate (Ritalin) on auditory processing in 32 children with both attention deficit hyperactivity disorder and central auditory processing (CAP) disorder. Analyses revealed that Ritalin did not have a significant effect on any of the central auditory processing measures, although…

Fragile X syndrome (FXS) is the most common inherited cause of mental retardation resulting in developmental delays in males. Atypical outer ear morphology is characteristic of FXS and may serve as a marker for abnormal auditory function. Despite this abnormality, studies of the hearing of young males with FXS are generally lacking. A few studies…

Changes in selection criteria have meant that children are being provided with cochlear implants (CI) at increasingly younger ages. However, there is a paucity of measures that are appropriate for testing complex listening skills--most tests are too cognitively complex for such young children. The Common Objects Token (COT) Test was developed as a…

The aim of this booklet is to: (1) help prepare British teachers for the challenge of having a hearing-impaired child in regular classes; (2) provide practical advice for these teachers to use in the classroom; and (3) suggest further sources of information and reading. Chapters provide information on: support services for hearing impaired…

The manual describes audiology services offered at the Model Secondary School for the Deaf (MSSD). Components are listed for diagnostic services, instructional services, program development, training, and publications. Testing and reporting procedures for MSSD students are outlined. Testing includes pure-tone air conduction testing, tympanometry,…

RECENT LINGUISTIC RESEARCH SHOWS THAT THE SPEECH PATTERNS OF SOUTHERN NEGROES CONSTITUTE A LEGITIMATE DIALECT OF ENGLISH WITH PHONOLOGICAL AND GRAMMATICAL RULES SOMEWHAT DIFFERENT FROM GENERAL AMERICAN ENGLISH (GAE). AN EXPERIMENT WAS DESIGNED TO DETERMINE WHETHER THOSE ASPECTS OF THE NEGRO DIALECT WHICH SET IT APART FROM OTHER ENGLISH DIALECTS…

Test presentation mode significantly affected test performance in two randomized groups of college students exposed to audio/visual and visual test modes. A significant difference was found between test presentation mode and mean test scores; the audio/visual test mode was superior to the visual test mode; and the "brighter" students seemed to…

This study examined the relationship between initial and final consonants on two equivalent forms of the Wepman Auditory Discrimination Test (WADT). Subjects were 128 first grade, English-speaking, Negro, disadvantaged children. The two WADT forms each contained 40 different word-pairs. Thirteen word-pairs differed in initial consonant (IPT); 13…

Various aspects of diagnostic evaluation and educational programing for hearing impaired children are described. Discussion of hearing disorders from a medical perspective covers anatomy of the ear, types and causes of hearing disorders, and medical and surgical treatment. A review of audiological assessment of hearing disorders focuses upon…

An audiometric screening survey was conducted on a severely and profoundly mentally retarded population using noise-makers and pure tone audiometry. Of those tested with noise-makers, 83% gave an identifiable response to sound, 7% did not respond, and 10% were considered difficult-to-test. By contrast, 4% passed, 2% failed, and 94% were…

In order to study effectiveness of low-frequency amplification and filtered-speech testing for preschool deaf children, an experimental design permitting the teacher to speak simultaneously through two different amplifying systems, a low-frequency auditory training unit (Suvag I) and a conventional auditory training unit (Warren T-2), was used…
