This study examined the means and standard deviations for the Auditory Memory Test Battery (Burford, 1976) using a sample of normal second, third, and fourth grade children. The study also compared span and sequence scores, low and high SES scores, and an individual's test scores with teacher judgment of intelligence group. A brief examination of the AMTB as used with LD children was also performed but not included in the statistical analysis.

Listening, as a communication skill, is an essential factor in the normal language development of the' child. Until recently, however, there has been very little research conducted concerning the linguistic parameters that influence the ability to listen. Thus, this investigation was designed to study the effects of two linguistic parameters, construction and semantic constraints on the verbal responses of preschool children in a dichotic listening task. Fifteen children, between the ages of 5-3 to 6-8, were presented with four dichotic listening tasks consisting of 80 stimuli, (40 sentences and 40 pseudo-sentences). The children were asked to report the message delivered to their right ear. The performance of the children was analyzed according to the F-Test and the Test of Least Significant Difference. The results showed that construction errors were the only statistically significant errors (P < .05) among the six types of error types counted in the listening tasks. There were fewer construction errors made when there was a meaningful message to report than when there was a non-meaningful one. Although the semantic parameters were not statistically significant in this study, other investigations have demonstrated their influence on the report of subjects in a dichotic listening task. Therefore, a future research project should be conducted placing a greater emphasis on the semantic parameters. Additionally, a three level listening hierarchy was found. It was based upon the number of construction errors that occurred among the four dichotic listening tasks. This writer feels that future research should pursue the question of an existing hierarchy among dichotic listening tasks. Such an investigation, however, should utilize a larger population than the population tested in this study.

Folklore has long held that blind people gain, relative to normal people, in their sensitivity to other sensory modalities. Although supported only by equivocal evidence, this position probably first appeared in mythology in early Greek literature. Oedipus Rex was attributed greater awareness of people’s nature after this blindness. It is still a prevalent myth in contemporary American culture, to the extent that it appears in “Little Orphan Annie.” Experimental attempts at verification of this point began several years ago, but it remains a controversial issue. Literature on the topic can be divided up into several content areas: the relevance of blindness to auditory sensitivity, the relevance of blindness to tactile sensitivity, the developmental effect of blindness and central vs. peripheral blindness and it affects perception. Studies sampled there represent these content areas.

This chapter presents information on aphasic auditory abilities, with specific reference to the following areas: (1) time-altered speech; (2) auditory sequencing ability of aphasics; (3) auditory discrimination ability of aphasics; and, (4) auditory perceptual disturbances cause by lesions in the left temporal lobe. Information will also be presented on the role of distinctive features in speech perception. Finally, the statement of the problem will be posed.

Rating scales are commonly used to study voice quality. The purpose of this study was to examine inter-rater reliability/agreement of graduate student clinicians with differing levels of experience in rating voice perception. The Consensus Auditory Perception Evaluation of Voice (CAPE-V) was used to asses 1.) overall severity, 2.) roughness, 3.) breathiness, 4.) strain, 5.) pitch and 6.) loudness from a sample of pediatric voices. Twenty-four graduate clinicians who had completed a graduate level course in voice disorders participated in the study. Twelve of the participants were randomly selected to complete a perceptual training course prior to the evaluation session. Voice samples included 10 disordered and 2 normal voices from a population of children age 3-10 years old. The 12 voice samples were randomly repeated 3 times. Results of analysis of variance indicated that the groups significantly differed in their severity rating of the perceptual indices, suggesting that training affected the participants' judgment of severity. Additionally, variability was reduced as a function of training. Pearson product-moment correlation coefficient's revealed a moderate to strong relationship for all of the perceptual indices suggesting that regardless of training participants have an implicit understanding of normal versus disordered voice samples.

The purpose of this study is to determine whether children with autism recognize the same perceptual voicing boundaries of stop consonants as normally developing children of the same age group. This was explored using three groups of participants: ten children with autism between the ages of 8-14, five typically developing children between the ages of 8-14, and five typically developing seven-year-old children. Children in all groups listened to initial stop consonant syllables with voicing contrasts, with voiced and voiceless cognates presented. The initial consonants were altered along a voice onset time continuum within the typically perceived boundaries of each consonant. Participants were instructed to select the box containing the letter of the initial consonant they perceive when they hear each syllable. Results revealed greater difference between the responses of the children with autism when compared with the older control group, than when compared with the younger children. The responses of the children with autism were more similar to those of the children in the second control group. This could be indicative of a delay in the children with autism of perception of the categorical boundaries along the dimension of voice onset time compared to typical children's perception of these consonants.
