Applicability of the Test of Visual Perceptual Abilities (TVPA) in diagnosing learning disabilities in hearing-impaired children

This paper studies the validity of the Test of Visual Perceptual Abilities (TVPA) as an indicator of learning problems in hearing-impaired children and how it correlates with other measures of learning disabilities.

Perceptual aspects of a three-dimensional vowel space

This dissertation examines the auditory-perceptual theory of speech perception and the concept and validity of perceptual target zones for vowels.

Visual perceptual skills, reading ability and the young deaf child

This paper is a review of a study investigating the relationship between visual perceptual skills and reading abilities of young deaf children.

Perceptual correlates of spectral changes in complex tones

This paper reviews a study of tonal precepts such as pitch and timbre as a means of facilitating auditory discrimination tasks.

Reanalysis of perceptual confusion matrices

This paper presents a study reformatting and reanalyzing data collected in a 1955 study of the perception of sixteen different consonants in consonant-vowel combinations, by human listeners.

Perceptual validation of an acoustic metric for measuring vowel production by deaf children

This paper discusses a study to validate the metric developed in the Geers and Moog Cochlear Implant Study at CID to measure the speech production of hearing impaired children.

Physical education and the hearing impaired

This paper compares the performance of perceptual-motor skills of physically and mentally normal hearing-impaired children who have participated in a physical education program with those who have not participated in a physical education program.

Perception and cognition in deaf children

This dissertation examines conceptual functioning of hearing impaired persons. Specifically the study addresses perceptual and conceptual functioning in both deaf and hearing children and whether there is a difference in performance as a function of hearing status, as attributable to age differences, or as a function of the school environment.
