The project was concerned with developing and testing self-instructional programs in communication skills for high school students. Initially the programs were presented in printed form; later two forms of presentation were used, printed and auditory. In the pilot studies students were put through the learning exercises individually. Two programs…

The technique of "voiceprint identification" has been invested with a myth of infallibility, largely by means of a specious analogy with fingerprints. The refusal of its chief proponent to submit to a properly controlled test of his ability, coupled with the inability of observers in independent studies to get comparably low error rates,…

The relationship between variations in an auditory signal identification task and consequent changes in the abilities related to identification performance was investigated. Characteristics of the signal identification task were manipulated by varying signal duration and signal-to-noise ratio. Subjects received a battery of reference ability tests…

The present report traces the rationale, development and experimental evaluation of the Diagnostic Discrimination Test (DDT). The DDT is a three-choice test of consonant discriminability of the perceptual/acoustic dimensions of consonant phonemes within specific vowel contexts. The DDT was created and developed in an attempt to provide a…

The text, designed for students and others interested in clinical audiology, is intended to provide comprehensive coverage of not only important concepts in audiology but particularly of the methods and procedures used in audiological assessment. The functions of tests, the administration of specific tests, and the analysis of test results are…

The primary aim of this study was to ascertain whether expectations affect children's performance on a measure designed to assess development of understanding of the Minimum Distance Principle (MDP) and its exceptions. There were three major hypotheses: (1) sentences harmonious with expectation should be more easily understood than neutral…

Sixteen kindergarten and 28 first-grade children were tested on two-choice discrimination problems. A prompt light indicated the positive (rewarded) object P on all training trials, and these were followed by a single nonprompted test trial during which a new object (X) replaced either P (X-N problems) or N (P-X problems) or neither (P-N control…

Four groups of male undergraduates were instructed to perform complex cognitive operations when randomly presented single digits of a dichotic listening paradigm. An erotic tape recording was played into the nonattended ear. Sexual arousal varied directly as a function of the complexity of the distracting cognitive operations. (Author)

In two experiments Ss (16 undergraduate students in the first, 14 in the second) listened to a sentence containing a brief tone, then wrote out the sentence and marked the location of the tone. (Author/SBH)

The principal objective of this study was to evaluate, in 21 severely hearing impaired children (9 to 12 years old), the relative effects of length of stimuli by closed set identification tasks. (Author/SBH)

A model was proposed as an alternative to current models for categorical perception, which refers to the apparent responding to stimuli only in absolute terms. The model proposed that a single (common) factor causes both a peak in the discrimination function and a categorical dichotomy and thus the correlation between the two. (Editor/RK)

The auditory assembly abilities of 30 stuttering and 30 nonstuttering children (all in grades 1-4) were investigated. (Author/SBH)

Teaching suggestions are offered for teaching spelling to poor spellers strong in auditory processing skills but weak in visual processing skills. (Author/DB)

The relationship between intraphonemic perception and identification of distorted /r/ was tested using nine graduate students in speech-language pathology with no known speech or hearing disorders. Laboratory training was found not to improve the identification of distorted /r/. Identification ability was related more to discrimination of /t-d/…
