Sixty monosyllabic, disyllabic, and trisyllabic words were recorded and presented at different times through earphones and vibrators to 20 normal adults and 20 profoundly hearing impaired children (ages 8 to 15 years) to evaluate perception of number of syllables. Vibratory perception by profoundly hearing impaired and normal Ss and auditory…

Eight newborn babies were tested to see whether they could make discriminating head-turn responses to the sound of a 9-second recording of a human voice coming 15 degrees, 30 degrees, and 80 degrees from the midline, from either the right or left side. Journal availability: see EC 113 765. (Author)

Four studies were conducted to investigate the relation between audition and vision in the human newborn. In all four studies visual activity was recorded with infrared corneal-reflection techniques in 1- to 4-day-old infants. (MS)

Two studies used sentence-picture matching tests of sentence comprehension in 69 adults with aphasia. Clustering analysis yielded groups of patients whose performance steadily deteriorated and was affected by sentence types that were harder for the overall group. Results provide data relevant to the determinants of the complexity of a sentence in…

A study involving 20 listeners investigated the potential influence of alterations in the temporal structure of speech produced during simultaneous communication on the perception of final consonant voicing. Results found that accurate perception was not impaired by the durational changes accompanying the typically slower speech pattern of…

Investigated the abilities of second language speakers to discriminate the prosodic contrasts between idiomatic and literal meanings of ambiguous sentences using utterances previously shown to be reliably identified by acoustic cues. (Author/VWL)

This commentary to EC 232 373 and EC 232 374 challenges the use of a speaker-based definition of stuttering and argues that use of the definition may only relocate the judgment reliability problem and raise as many validity problems as a listener-based definition of stuttering does. (JDD)

A forward-gating procedure employing familiar monosyllabic words was used in auditory testing of age- and gender-matched elementary students with and without learning disabilities. Results indicate auditory closure skills were comparable between disabled and nondisabled subjects, but sensory discrimination problems may contribute significantly to…

The study investigated (1) the reliability of children's (N=10 in grades 1, 3, and 5) judgments of vocal roughness, (2) normal-abnormal cut-off values for these judgments, and (3) children's ratings versus adult clinician ratings of the same samples. Results indicated child judgments commensurate with that of clinicians. (Author/DB)

Auditory-visual pattern equivalence and temporal-spatial equivalence of 72 children of 7-17 years were examined. Data indicated that aspects of intersensory integration were still developing between the ages of 13 and 17. Accuracy in performance increased with age for intra- and intersensory matching. (RH)

No differences were observed between six adults and six six-year-olds in measures of frequency selectivity and comodulation masking release. Children were less able to detect signals in noise backgrounds where the signal had perceptual qualities similar to the noise or in noise backgrounds having high degrees of fluctuation. (Author/JDD)

Reviews and critiques a doctoral dissertation that investigated the ability to detect tempo changes. Points out some omissions in the study, suggesting that its brevity caused the author to omit some possible interpretations. Comments that Ellis' research design provides new ideas for research. (LS)

Two studies examined the relationship between speech perception and speech production errors in children (N=21 and ages 5 and 7) with articulation disorders. Findings indicated the existence of a subgroup of articulation disordered children for whom production errors reflect perception errors. (Author/DB)

A profile analysis procedure was used with the Carrow Auditory-Visual Abilities Test to aid in the identification of systematic modality preferences in two preschool children with articulation disorders. Critical values are identified to facilitate the identification of the child's strengths and weaknesses at the subtest level. (Author/DB)

The ability of 10 normal-speaking 5-year-olds and 10-normal-speaking 7-year-olds to categorize consonants as "dripping" (stop), "flowing" (fricative), "tongue" (lingual place of articulation), "or "lip" (labial place of articulation) was evaluated. Children's ability to categorize was evaluated as an indicator of their awareness of feature…
