Thirty children with profound hearing impairments were followed over a three-year period with a semiannual battery of speech perception tests. Testing utilized multichannel tactile vocoders in variations of tactile and/or auditory/visual conditions. Performance in the tactile plus auditory condition generally exceeded that in other conditions,…

The speech perception performance of 10 congenitally deaf and 3 postlingually deafened children who received multichannel cochlear implants were compared at preimplant and 6-month intervals up to 2 years. The congenitally deaf children did not exhibit measurably improved performance until after 12 months or more of implant use, whereas…

Describes an experiment to verify the Compton collision formula and the angular dependance of the Klein-Nishina formula. Equipment used is a 1-mCi(137)Cs source, 2x2 in. NaI detector and a multichannel analyzer. Suitable for honor undergraduates. (Author/GA)

Describes a flexible, multichannel, highly accurate, digital data acquisition system for use with a microcomputer. Includes a description of instrumentation for computer data acquisition, data acquisition systems, software, uses in the curriculum, library interaction and action, and use in a mechanical engineering laboratory.

New technologies have been developed to diagnose such disorders as cancer, heart disease, and defects of the newborn in presymptomatic stages. Several technologies, including amniocentesis, radioimmunoassay, enzyme immunoassay, multichannel analysis and others are discussed. Development of these technologies and issues related to their use are…

Discusses sensory-perceptual abnormalities in people with autism from published firsthand accounts and existing psychological research evidence. A range of abnormalities, including hyper- and hyposensitivity, sensory distortion and overload, and multichannel receptivity and processing difficulties, are described and the limitations of clinical and…

The results of an experimental Spanish course using videotapes, described previously (FLA, December 1974), and the application of the results to the entire Spanish language program, are discussed. (Author/KM)

Surveys 197 respondents to measure leisure-time activities. Analyzes four different TV groups to look for group differences in two types of channel repertoire: broadcast channel repertoire (BCR) and cable channel repertoire (CCR). Finds differences among groups for CCR but none for BCR. Supports the idea that people who are active in general tend…

A case study of a child who was stimulated with a cochlear implant at age 25 months is reported. Postimplantation, nasals decreased and other consonant types increased, particularly alveolars. The vowel space expanded, including increased production of diphthongs. Serial organization of speech postimplantation mirrored basic motor propensities in…

Includes the announcement of the first World Congress on Future Special Education, a multi-channel tape playback system designed to enhance career guidance and counseling services in Southern California, and a report from the National Association of Independent Schools on student enrollment and some important characteristics of independent…

A technician auto analyzer (consisting of six modules: sampler, multichannel peristaltic pump, dialyser, heating/incubation bath, colorimeter, and recorder) was modified by using key modules and substituting standard equipment for others; spectronic 20 with homemade flow cell for colorimeter module. Descriptions and diagrams of the apparatus are…

The effects of a rapid change in media environment are examined through the introduction of a multichannel cable television system in Israel. Findings highlight changes on the behavioral, cognitive, and affective dimensions. Changes occurred in reallocation of leisure time, social characteristics of viewing, viewing patterns, and content…

Laboratory results are presented which suggest that hearing-impaired individuals' speech perception can be enhanced through use of tactile aids with a number of tactile transducers conveying information about the spectral content of the speech signal, and speech production can be improved through experience using a multichannel tactile aid.…

This article chronicles changes in vowel production by a child with congenital deafness who received a multichannel cochlear implant at 19 months. The child exhibited three vowel types before implantation, however, a total of nine different vowel types were observed during her first year of implant experience. (Contains references.)

Verbal and nonverbal cues were studied in a multichannel communication paradigm to assess their effect on the communication of empathy, respect, and genuineness. Counselors and clients rated videotaped interactions between counselor and client, each portraying a different combination of verbal message, trunk lean, eye contact, vocal intonation,…
