A study was undertaken to learn whether involvement of the brain's right hemisphere in auditory language processing, a phenomenon found in a previous study of Crow-English bilinguals, was language-specific. Alpha blocking response as measured by electroencephalography (EEG) was used as an indicator of brain activity. It was predicted that (1)…

The concept of "preliteracy" is important for adult literacy programs. All illiterate adults can undertake their initiation into the world of letters and figures provided they are strongly motivated to do so. Experiments on motivation indicate that literacy programs must respond at least to one essential need of the future literate…

In a study that investigated differences in the processing styles of beginning readers, a Pictograph Sentence Memory Test (PSMT) was administered to first and second grade students to determine their processing style as well as to assess instructional effects. Based on their responses to the PSMT, the children were classified as either visual or…

Problems related to the structure of the mental lexicon are considered. The single access assumption, the passive memory assumption, and the heterogeneous memory assumption are rejected in favor of the theory which assumes several active memories, each able to store expression based on only one homogenous set of abstract primitives. One lexicon…

Thirteen manuscripts and extended reports on the nature of speech, instrumentation for its investigation, and practical applications of research are presented in this status report on speech research for the period of July-December 1979. The topics dealt with include speech perception, children's memory for sentences and word strings in relation…

This report covers research conducted between July 1972 and March 1973. Experiments were conducted on the automatic detection of constituent boundaries and location of stressed syllables by analysis of fundamental frequency and energy contours, for recordings of six talkers reading the Rainbow Script, two talkers reading a paragraph composed of…

The concurrent and discriminant validity of La Prueba de Analisis Auditivo, a Spanish auditory perception test, and the validity of the perceptual deficit hypothesis and of hypotheses derived from verbal processing theory were evaluated in a sample of 114 second-grade Hispanic pupils receiving reading instruction in Spanish. (Author/BW)

The percent and characteristics of children who produced invalid profiles on two different continuous performance tests (CPTs) tasks were examined. Sixty-one children referred for attention deficit hyperactivity disorder (ADHD) assessment and 24 non-clinical control children (all children ages 5-16) were given the Test of Variables of Attention…

The relationship between modality styles and reading achievement was studied for 51 first graders given 2 subtests of the Swassing-Barbe Modality Index, 2 subtests of the Illinois Test of Psycholinguistic Abilities, and 2 tests of nonsense words. There was no significant interaction between modality preference and reading achievement. (SLD)

Reports results of the administration of a battery of tests of oral language skills to blind braille readers (N=15). Three skills were tested: phoneme deletion, sentence completion, and morphological analysis. Participants were congenitally blind high school students. Subjects differed from sighted readers only in the ability to perform…

Ten children, adolescents, and prelinguistically deafened adults implanted with cochlear implants exhibited substantial postoperative benefits in open-set speech perception, with some improvement in closed-set speech recognition. Results are discussed with reference to such variables as age at onset of loss, duration of profound loss, age at…

This study, involving 24 young and elderly normal-hearing adults, addressed the effects of aging on auditory serial-recall performance for natural and synthetic words. Serial recall of monosyllabic words was not affected by age per se or by rate of presentation, but word difficulty affected recall for both groups. (Author/JDD)

A study compared continuous discourse tracking rates in eight children (ages 8-14) with hearing impairments and eight typical children using three competing noise conditions: classroom noise, videotaped classroom activity, and combined noise and visual activity. Statistical analyses showed no significant differences among tracking rates due to the…

A study used impulse response measures and observations in 10 Florida classrooms to develop 10 recommendations for improving the acoustical environment in schools. Recommendations include improving air-conditioning systems, limiting room volume, providing sound-absorbing surfaces, using carpeting, reducing distance between teachers and students,…

Reports on the perceptual discrimination of segmental and suprasegmental phones by Japanese learners of English. Results reveal that early learners showed better discrimination performance than normal learners and confirmed the usefulness of learning English at an early age. (16 references) (Author/CK)
