A proximal cause of reading disabilities is a deficit in phonological processing. A consequence of this deficit is inferior performance in one or more cognitive operations that use phonological information, including phonological awareness, lexical retrieval, and verbal memory. Some assert that these phonological processing difficulties are the…

Event-related potentials (ERPs) to tone pairs and single tones were measured for 16 participants with specific language impairment (SLI) and 16 age-matched controls aged from 10 to 19 years. The tone pairs were separated by an inter-stimulus interval (ISI) of 20, 50 or 150 ms. The intraclass correlation (ICC) was computed for each participant…

The purpose of the current study was to examine the role of syllable duration context as well as static and dynamic acoustic properties in child and adult speech perception. Ten adults and eleven 4?5-year-old children identified a syllable as [ba] or [wa] (stop-glide contrast) in 3 conditions differing in synthetic continua. The 1st condition…

We propose an "Enhanced Perceptual Functioning" model encompassing the main differences between autistic and non-autistic social and non-social perceptual processing: locally oriented visual and auditory perception, enhanced low-level discrimination, use of a more posterior network in "complex" visual tasks, enhanced perception…

In this project, the hypothesis of an auditory temporal processing deficit in dyslexia was tested by examining auditory processing in relation to phonological skills in two contrasting groups of five-year-old preschool children, a familial high risk and a familial low risk group. Participants were individually matched for gender, age, non-verbal…

This study attempts to investigate the role of sensorimotor impairments in the reading disability that characterizes dyslexia. Twenty-three children with dyslexia were compared to 22 control children, matched for age and non-verbal intelligence, on tasks assessing literacy as well as phonological, visual, auditory and motor abilities. The dyslexic…

This guide is intended to help the literacy practitioner in the identification of adults with learning disabilities. These adults have worked diligently for a year or more to improve comprehension skills, writing and spelling, or work skills, yet, have made little progress. The role of screening as only the first step in a process involving a…

This paper describes adult symptoms of Central Auditory Processing Disorder and provides strategies for dealing with this disability. Symptoms include talking or turning on the television louder than normal, interpreting words too literally, needing remarks repeated, having difficulty sounding out words, ignoring people, being unusually sensitive…

This paper reports on a small-scale pilot study further investigating the perceptual development in the acquisition of durational contrasts by different levels of adult English-speakers of Japanese. Four kinds of naturally spoken word-tokens were edited by a synthesizer to generate word-stimuli varying the duration of a certain consonant/vowel…

Three major categories of instruction for a course designed to teach community college students how to effectively listen are functional listening, awareness of auditory disabilities, and interpersonal listening. In functional listening, students learn to listen for the main idea, identify supporting points, summarize accurately, avoid…

A study consisting of two experiments attempted to further adapt the visual preference procedure for determining children's meaningful phonological perception. In the first experiment, 1-year-olds were presented with auditory stimuli (words) and screens containing paired color photographs of the object described by each word and of an unusual…

The HPI Texas Preschool Screening Inventory (TPSI) is a test to help determine which children might be a risk for learning problems as they enter kindergarten or first grade. The HPI Manual describes the procedure, score interpretation, and rationale for seven components of the test, including auditory memory for numbers and letters, visual memory…

A preliminary experiment was conducted to explore the effects of illiteracy on hemispheric specialization. Groups of literate and illiterate Iranian children were tested on three dichotic tapes consisting of monosyllabic animal names, double-digit numbers, and nonverbal environmental sounds. All children were also tested for handedness and for…

Three ten-step series of synthetic speech stimuli were constructed: /raem/ to laem/, /raem/ to /waem/, and /laem/ to /yaem/. Within each series, differences consisted of variations in onset frequency and slope of transition in the second or third formant. These stimuli were presented to 5- to 7-year-old children in identification…

The purposes of this study were to determine the modality strengths of each child in grades 1 to 5 at Butcher Children's School, Emporia, Kansas, and to ascertain whether modality can be linked to grade level, to reading achievement, or to sex. For identifying modality strength, the Swassing-Barbe Modality Index (SBMI), a matching-to-sample task,…
