▼ The purpose of this study was to examine the development of the primary auditory cortex (AI) in the ferret. This study was conducted using five sable ferrets (Mustela putorius furo) of the following ages: (1) postnatal age 11 (2) postnatal age 18 (3) postnatal age 25 (4) postnatal age 32 and (5) postnatal age 63. Each subject was perfused transcardially with physiological saline, followed by tissue fixation using 4% paraformaldehyde in 0.1 M sodium phosphate buffer (pH 7.4). Each ferret was then decapitated, and the skull was dissected to allow removal of the brain, which was stored in the same fixative. The auditory cortex of each ferret was dissected from the whole brain and subsequently embedded in a gelatin and egg yolk solution. The embedded tissue blocks were then immersed in 4% paraformaldehyde for 72 hours and then sectioned using a vibrotome. Sections cut in 70 µm increments were stained using cresyl violet, and qualitatively analyzed using a light microscope. The results of this study supported previous findings, indicating that the laminar structure of the primary auditory cortex is in place by postnatal day 18 in the ferret. Additional studies investigating the laminar structure in younger ferrets and utilizing cell counts is recommended.

▼ A pilot study examined caregivers’ expectancies of their child’s speech-language therapy prior to treatment. Specific caregiver and family characteristics (i.e. socioeconomic status, caregiver stress levels, and family status) were analyzed to determine if these predicted high or low expectancies of speech-language therapy. Because of the low number of participants (15 respondents), the present study is not representative to draw conclusions about caregiver expectancies. Likely due to the small sample number, the lack of participation of single and low income caregivers, and the absence of ethnic minority participants, a relationship between caregiver expectancies and socioeconomic status, family status, ethnic status, and parenting stress could not be determined. The results based on the small sample indicated that socioeconomic status, caregiver stress, and family status did not predict high or low expectancies. Despite the small sample, statistical significance was identified in caregivers’ agreement to high expectancy statements and disagreement to low expectancy statements. Additional findings showed that 26.6% of the caregivers scored at a high total stress score. Within the group of the 26.6% that scored at a high total stress score, 75% scored at an even higher total stress score indicating clinically significant levels of stress. Overall, the findings have implications for the need to understand caregiver stress, the factors that influence caregiver stress, and its impact on intervention and treatment outcomes.

▼ Objective: To investigate the listening environment of classrooms and determine if they have changed over the past century. This hypothesis will be investigated through measurement of sound level readings, calculation of reverberation time, and documentation of the listening environment when each classroom is unoccupied. Methods: Ambient noise levels and reverberation time were measured for eighteen unoccupied classrooms. The classrooms studied included three buildings constructed in 1999-2001; four buildings constructed between 1906-1931, and two buildings constructed in 1960-1962. Two classrooms were measured from each building in the categories listed above. Results: The results indicated a significant correlation between construction age of the classrooms and reverberation time (RT) in the direction of better reverberation time after the 1960's. Surprisingly, there were no significant relationships found between RT and volume of the classrooms or ambient noise levels and age of the buildings sampled.

▼ This thesis explores ways in which international teaching assistants use discourse to construct the role of teacher during a mandatory oral English proficiency test administered by the University of Cincinnati. Using an iterative, grounded theory approach to discourse, this study explores the ways in which power, social distance, gender, and culture interact to influence the construction of the teacher role. Thematic analysis of videotaped tests, memo writing, case comparisons, and continual literature review intertwine to unpack how international teaching assistants “bring off” the role of teacher. The discursive management of identification emerges as a key thematic cluster in the construction of the teacher role.

▼ The purpose of this study was to test for the significance of the association between the Fukuda stepping test and bithermal calorics of Electronystagmography, (ENG). The results of the presence or absence of a positive Fukuda and percent of unilateral weakness were examined to determine if the Fukuda stepping test could be used as a second indicator of a peripheral vestibular pathology. Ten subjects with caloric unilateral weakness and 15 control subjects were included in the study. Each group performed the subtest calorics of the ENG and the Fukuda stepping test. This study found no significant association, except due to chance between the Fukuda stepping test and caloric weakness as tested by the Chi Square analysis.

▼ he purpose of this study was to discover if a naturalistic teaching technique, used by Koegel, Camarata, Valdez-Menchaca, and Koegel (1998) with children with autism, could be applied to a young subject with autism/PDD who used an augmentative communication device, in order to instruct her to ask "what's that?" questions. Additionally, the research tried to determine if a significant difference existed between the number of "what's that?" questions generated when the child with autism/PDD was with a familiar communication partner compared to an unfamiliar communication partner and was provided with preferential items. It also focused on discovering if a significant difference existed between the number of "what's that?" questions generated when the child with autism/PDD was with a familiar communication partner compared to an unfamiliar communication partner and was provided with non-preferential items. Intervention sessions were conducted with the subject, and the data collected from them was categorized. The "what's that?" questions asked by the child were classified as either spontaneous or cued. The most significant result of the research study was that the subject was able to acquire the ability to generate "what's that?" questions using her augmentative communication device as a result of the training sessions. The intervention sessions resulted in the subject demonstrating a statistically significant increase in her ability to ask "what's that?" questions when compared to the baseline measurement. Yet while the subject asked more "what's that?" questions when provided with preferential items and when interacting with a familiar communication partner, the difference was not statistically significant when compared to the number of queries formulated when she was with an unfamiliar communication partner. However, the results also determined that while the subject generated a greater number of "what's that?" questions when provided with non-preferential items and when interacting with an unfamiliar communication partner, the difference was not statistically significant when compared to the number of questions asked when she was with a familiar communication partner.

▼ This study investigated, through a questionnaire, the home literacy environments of 71 second-grade students. This questionnaire inquired about the types, places, and purposes for which literacy is used in the homes of these school-aged children. The study investigated how parental attitudes and level of education correlated with the home literacy environment. The study also investigated how types and places for literacy experiences correlated with other aspects of the literacy environment. Results revealed common home literacy practices of reading newspapers and writing lists. Common literacy purposes were environmental reading and writing for memory aids. No significant correlations were found between parental attitudes and the home literacy environment as a whole, yet significant correlations were found between parental education level and this environment. Types of literacy experiences in which parent/caregivers participated and places for literacy experience correlated with aspects of the home environment. These findings and their implications will be discussed.

▼ The purpose of this study was to determine whether collaboration occurred between an individual using Facilitated Communication and his facilitator or if the facilitator influenced the communicator's responses while determining if learning resulted from the administration of multiple tasks with the same stimuli. The subject was a 26 year old male diagnosed with autism who was facilitated by his mother, a licensed speech language pathologist. A total of 120 trials divided evenly among four different conditions were administered. Overall performance on the test items indicated that the selection of pictures seen by the communicator were not due to chance. The presence of collaboration between the communicator and facilitator, however, could not be validated from this study. The responses of the facilitated communicator indicate that learning may have occurred through repeated trials. Additional studies to analyze learning and collaboration between communicators and facilitators are recommended.

▼ This study examined the effects of different presentations of cause-effect expository text for students with language learning disabilities. The method in which comprehension was assessed was through a retelling. Modes of presentation included Oral and Written only, Oral and Written Followed by Graphic Organizer, and Graphic Organizer Followed by Oral and Written. Analysis was quantitative, descriptive and qualitative in nature. Frequency of identification of main idea, cause, effect, and cause-effect pairs were measured. Statistical significance was not found between the various modes of presentation. Additionally, this study examined the nature of expository text that the retelling represented. These included description, sequence, summary and cause-effect. The findings in this study raised many issues that involve comprehension of expository text. Implications are discussed.

(more)
▼ This study examined the relationship among phonological perception, verbal working memory, and linguistic performance in youngsters with Down syndrome (DS). This population was selected due to the well-documented deficits that individuals with DS display in the auditory modality. Although phonological perception and verbal working memory skills are widely recognized as prerequisites for language acquisition, few attempts have been made to examine the effects of decontextualized practice in these areas on the development of syntactic and semantic aspects of linguistic performance. Morphosyntactic skills and propositional complexity were the linguistic features that were the focus of this study. Participants received intensive treatment with the Earobics software program which purports to develop the phonological perception and working memory skills necessary for oral language development. Prior to and immediately following participation in the Earobics program, conversational language samples were gathered from the 27 participants. Language samples were analyzed for 13 grammatical morphemes and three measures of semantic/propositional complexity. Although participants demonstrated significant differences in performance on standardized tests of verbal working memory and phonological perception, there were no significant differences in linguistic performance during conversational speech. Results of this study suggest that decontextualized practice in aspects of phonological perception and verbal working memory is insufficient as a scaffolding tool for building broader aspects of linguistic performance. Implications for future research and clinical practice are discussed.

▼ This investigation attempted to develop a test for assessing intelligibility of native Spanish-speakers with dysarthria. Twenty-five native Spanish-speakers participated in this study. Eleven were diagnosed with Parkinson’s disease and 14 subjects free of neurological disease served as a comparison group. Subjects read a list of Spanish minimal pair phonetic contrasts randomly presented. These phonetic contrasts were prepared by the investigator and have been considered to be sensitive to dysarthric impairment and contribute to speech intelligibility in English speakers with dysarthria. Responses were digitally recorded. A group of 25 native English speaking graduate students in speech-language pathology and 6 native Spanish speaking professionals served as judges in a perceptual task of intelligibility. Judges listened to the digitally recorded speech samples from the Parkinson’s and comparison groups. English speaking listeners recorded responses by transcribing phonetically what they heard. Spanish speaking listeners wrote their responses orthographically. Scores of intelligibility were awarded to each speaker based on the number of correct responses by each listener. The subjects with PD were found to be less intelligible than the comparison group by both the English and Spanish speaking judges. Acoustic analysis of VOT, vowel space, and F2 transitions for each speaker were examined. Significant differences were found between groups for VOT and vowel space. A trend was also exhibited between groups for F2 transitions although this was not found significant at the .05 level. Regression analysis revealed that VOT was a strong predictor of intelligibility, accounting for 57% of the variance.

▼ This case study examined the turn taking interactions exhibited between a child identified with autism spectrum disorder and a typically developing peer of the same age. The subjects were involved in a peer play intervention program held in the home of the child with the identified disability. Measurements included the number of initiations turns made by each subject, the percentage of these initiations that were successful in leading to engagements, the number of turns per engagement for each subject, and the total number of turns for each subject per baseline across baselines. Further analysis looked at the percentage of continuous turns vs. discontinuous turns, and the different forms of continuous and discontinuous turns that were exhibited by each subject. The results showed that the typically developing peer increased in his initiations for engagement; however, the child with autism did not show a consistent pattern of change in his initiations across baselines. Neither subject demonstrated a consistent pattern of change in their percentages of successful initiations across baselines. Each subject demonstrated an increase in their mean and maximum number of turns per engagement during baselines that followed adult intervention. Both subjects also demonstrated an increase in their number of total turns per play session during baselines following adult intervention. Neither subject's percentage of continuous turns exhibited a consistent pattern of change across baselines.

(more)
▼ Although parent-professional agreement regarding children's developmental skill levels has been studied in the population of children with developmental delays, few attempts have been made to examine agreement of language developmental age level in children with Pervasive Developmental Disorder/Autism (PDD/Autism). Even fewer researchers have examined agreement at the re-evaluation when it can be speculated that the parent is more informed. In addition, agreement across specific language areas, and agreement across test environments and methods have not been examined. The purpose of this research was to evaluate parent-professional agreement regarding children's language skills at the re-evaluation, across specific language components, such as language understanding, production, and pragmatic skills; across settings, including clinical and non-clinical; and across testing methods, including standardized and non-standardized, when the diagnosis is PDD/Autism. Forty parents and their children with the diagnosis of PDD/Autism were re-evaluated in the clinic and in the special needs classroom of a children's hospital in a major Midwestern city. Data from the evaluations was analyzed using quantitative methods. Results of the study showed significant parent-professional difference in several areas and agreement in other areas. Parents rated their children's receptive, expressive, and total language skills higher than when the professional testing was completed with a standardized instrument, in a clinical setting. When specific receptive and expressive language skills were examined across two environments, parents agreed with the professional's standardized findings in the clinic, and non-standardized findings in the classroom, more than half of the time (closest agreement occurred between parent report and professional, standardized findings for specific receptive skills in the clinic). The parents reported less use of pragmatic language at home, and the professional observed more frequent use of pragmatic language in the classroom. Parents agreed with the clinician regarding the children's vocabulary skills when the professional used both a standardized and a non-standardized evaluation instrument.

▼ The purpose of this study was to find out how hearing aids are cared for in nursing homes by examining the condition of the hearing aids, resident satisfaction with the hearing aids, healthcare provider attitudes about hearing aid maintenance, and amount of knowledge on the part of both the residents and healthcare providers about how to maintain proper function of hearing aids. Thirty-four non-demented nursing home residents who owned at least one hearing aid and 17 healthcare providers that worked closely with the residents were asked specific questions related to hearing healthcare. The overall results indicated that the majority of nursing home residents and staff do not possess adequate knowledge about maintaining hearing aids to keep them properly functioning. Implications of this finding are discussed. It is recommended that a hearing aid reference guide created specifically for healthcare providers become available for use when faced with a hearing aid issue.

(more)
▼ Voice therapy can improve the vocal quality of elderly patients with voice problems, but little is known about what happens physiologically. The purpose of the present study was to determine the effect of the management program known as Vocal Function Exercises (VFEs) on vocal aerodynamics and perceptual quality of voice. The effect of subject physical fitness level on change in VFE time was also considered. There were 24 subjects (19 experimental, 5 control) ages 60-78. The experimental group was subdivided into 3 fitness groups: Sedentary, Active, and Fit. The experimental group performed VFEs twice a day for 12 weeks, while the control group performed them once a week for 12 weeks. Aerodynamic measures of glottal airflow were collected at comfortable, high, and low pitches both before and after the 12-week exercise program. Statistical analysis revealed the Fit and Active subjects did not reach a plateau on the VFEs more quickly than the Sedentary subjects. The Sedentary group did not demonstrate a greater magnitude of change than either the Active or Fit group. For vocal aerodynamics, significant differences occurred between the experimental and control groups for selected measures. A logistic regression analysis revealed minimum flow and subglottal pressure (Psub) to be most sensitive to the effects of the VFEs. Perceptual analysis revealed that those subjects rated the most dysphonic improved their vocal quality, though the extent of change was limited due to the number of subjects with normal/mildly dysphonic voices prior to the exercise program. Interpretation of the aerodynamic results indicated that as a result of performing VFEs, greater vocal fold closure was achieved with a concomitant increase in Psub. Trends gleaned from the nonsignificant results in the aerodynamic measures supported this, particularly because there was no concurrent increase in intensity. Improvement in the VFE times also mirrored the improvement in vocal fold closure. The magnitude of change in the aerodynamic measures between the experimental and control groups might have been greater had the exercises been performed with greater intensity. Greater improvement in perceptual quality could be expected with a more dysphonic group of subjects.

(more)
▼ Ménière's disease is a progressive disorder of the inner ear consisting of a quadrad of symptoms: 1) fluctuating hearing loss, 2) aural fullness or pressure 3) roaring tinnitus, and 4) episodic vertigo. The etiology of Ménière's disease is not known, but its pathophysiology is believed to be due to endolymphatic hydrops, or excessive endolymph pressure in the inner ear. If some disease is found that is believed to have precipitated the Ménière's disease, a physician will attempt to manage the symptoms medically, with low salt diet, diuretic, and avoidance of caffeine and nicotine. However, in many cases the disease will continue to progress, uncontrolled by medical intervention. These cases will require some form of surgical intervention to alleviate the debilitating symptoms associated with Ménière's disease. In the past, 3 main surgical alternatives have been considered as options to alleviate Ménière's disease symptoms: 1)endolymphatic sac decompression, 2) surgical vestibular neurectomy, and 3) labyrinthectomy. However, more recently, a less invasive medical/surgical treatment has been introduced. Intratympanic chemical vestibular neurectomy involves injecting an aminoglycoside through the tympanic membrane, or eardrum, and into the middle ear space where it perfuses through the round window membrane and into the inner ear spaces in order to destroy diseased nerve cells and alleviate symptoms associated with these nerve cells. This study seeks to analyze the effect of Streptomycin chemical vestibular neurectomy on subjects' daily functional levels, or the extent to which they are debilitated by the disease, and hearing acuity (pure tone and word discrimination scores) at three points in time: 1) pre-treatment, 2) 2 months post-treatment, and 3) 18 months or longer post-treatment. Results indicate that there is a statistically significant improvement in functional level immediately post-treatment (2 months) compared to pre-treatment, which sustains over a given period of time (18 months or longer post-treatment). Results also indicate that there is no statistically significant change in hearing acuity, pure tone or word discrimination score, immediately post-treatment (2 months) or over time (18 months or longer). Finally, subjects whose functional levels improved showed no significant change in hearing acuity over time.

(more)
▼ Objective: This thesis investigated the hearing status of neonates born to mothers with either gestational diabetes mellitus (GDM) or preexisting diabetes mellitus (DM). Past research has explored how metabolic alterations and other complications due to maternal diabetes affect neonates. However, few studies have examined the hearing status in infants born to diabetic mothers. Methods: Distortion product otoacoustic emission (DPOAE) data were gathered, bilaterally, at the frequencies of 2, 3, 4, and 5kHz from infants born to mothers with GDM and DM and from infants born to mothers without diabetes. A two-way analysis of variance for repeated measures was used on randomly selected ears to determine if there was between-group significance (control vs experimental) and/or a within subject (frequency) significance. All of the DPOAE amplitudes in each of the subjects were plotted against a range of normative data. Results: The results of the ANOVA suggest that there was not a significant group effect, and therefore no difference in DPOAE amplitudes were discovered between the control and the experimental group. A frequency effect was found to be significant but was influenced by the noise floor measures at the individual frequencies. The majority of the DPOAE amplitudes fell within a +/-2 standard deviation of the normative data. Discussion: There was no significant group difference for the DPOAE amplitudes. However, very low statistical power was observed for this between-group difference which could explain the insignificant findings. A trend for larger DPOAE amplitude in the infants of diabetic mothers was noted, and this same trend was discovered by Johnson (2000). Future studies should incorporate a larger population sample. Also, the noise levels should try to be controlled when conducting quantitative studies with DPOAEs as excessive noise levels may present as a confounding variable.

(more)
▼ Traumatic brain injury (TBI) affects millions of individuals each year, and is the leading cause of death and disability for individuals under age 40. For many individuals who incur mild, moderate, or severe TBI, college attendance is an age-appropriate and feasible activity despite the presence of cognitive, communicative, behavioral, and physical impairments associated with the injury, many of which may be subtle. However, it is asserted that many individuals with TBI who attempt to meet the challenges of college entry or re-entry require a strong network of support in order to successfully manage the transition from post-injury convalescence or rehabilitation to the rigors of the academic environment. An important link in such a support network can be the provision of cognitive-linguistic therapy designed to remediate higher-level cognitive skills necessary for academic success. The present study sought to determine if academically oriented cognitive-linguistic therapy services are desired by high school and college-age students with mild, moderate, and severe TBI. Demographic data and information about provision of inpatient and outpatient speech-language services were collected from patient charts at two local facilities. Telephone interviews were then conducted to acquire additional information. Overall, results of the study indicate that there is a desire for cognitive-linguistic therapy designed to address higher-order cognitive and communication skills among local high school and college-age students who have incurred TBI. Results also show that improved identification of individuals with mild TBI and broader knowledge of potentially significant impairments associated with mild TBI are needed in order for individuals with mild TBI to receive the patient education and services they need for facilitation of successful recovery.

▼ The purpose of this study was to determine if perceptual or taxonomical information provided in a story influences children's choices in a novel word-learning task. The study separately examined three and five-year old children's classification of a novel noun when presented with a choice of either a perceptually related object or a taxonomically related object. The first task of the classification task included the presentation of a line drawing of an object, in which the researcher orally labeled the object with a novel word ("koob" or "doop"). The children were shown a set of three pictures and asked to choose the other "koob/doop". In the second task, the children chose the named object (koob/doop) from a set of three pictures after hearing a story about the novel word. Results for three-year olds revealed that when they were shown the picture first, they chose the perceptually related object (from a choice of three pictures) significantly more often than the taxonomically related object. While four out of five children chose the taxonomically related picture when told the story first, there was no significant difference in the picture choices. The children did not choose the perceptually related picture more often when the story was presented first. The five-year old results revealed there was no significant difference in the picture choices when the picture was presented first. However, there was a significant difference in the picture choices when the story was told first. Five-year olds chose the taxonomically related object more often after hearing taxonomic information about the novel noun. Subjects in both age groups did not change picture choices from one task to another.

▼ The demographic and diagnostic trends of patients receiving FEES exams at a pediatric facility were examined. Relationships between diagnosis type, findings, recommendations, and other dysphagia evaluations were investigated. Data were collected from 99 pediatric FEES reports performed from April through December of 2001. The average age of a patient receiving the FEES exam was 49.47 months (approximately 4 years). A greater percentage of the patients in the study were males (59.6%) than females (40.4%). Males were also more prevalent in every diagnostic category, except those with a cardiovascular diagnosis where females dominated. The most frequent diagnoses were neurologic, structural, and other (congenital, acquired, and miscellaneous). Variations among findings and recommendations were found between diagnostic categories. Premature spillage was the most frequent finding across all diagnostic categories.

▼ Corporate Speech-Language Pathologists work as consultants with corporate employees in the areas of accent modification and speech improvement. However, research in this area of service has been minimal. An examination of the two major approaches to pronunciation training (segmental and multi-segmental) should be addressed when planning treatment goals. In addition, attention should be given to specific techniques that will be utilized in order to promote improvements in pronunciation, especially in day-to-day life contexts. The purpose of this study was three-fold: (a) to evaluate differences in trained listener ratings of pre/post performance in pronunciation for ESL speakers participating in a pronunciation training program, (b) to determine if there were differences in characteristics of goals, approaches and techniques used with subjects demonstrating “high” and “low” levels of pronunciation improvement, and (c) to determine if there were differences in untrained listener ratings of pre/post performance in pronunciation for ESL speakers participating in a pronunciation training program. An adapted screening protocol was developed to determine the effects of pronunciation training on the speech of 12 adult Mandarin Chinese speakers receiving training and 15 Mandarin Chinese speakers who received no training. Both groups were given pre and post assessment tests. The screening protocol assessed the areas of articulation, rate, intonation and loudness. After receiving pronunciation training, the experimental group was rated by a group of 15 untrained listeners. The parameters used to rate the untrained listeners were articulation, rate, intonation, and loudness. Results of this study support the idea that improvement in pronunciation occurs over time, but does not necessarily depend on formal training. A post-hoc analysis revealed that although subjects attended pronunciation training for a total of 7 sessions for 45 minutes each, their improvements were similar to those who did not receive any pronunciation training. It also revealed that since subjects in both the experimental and control groups had been in the United States for approximately 2 months prior to beginning pronunciation training, it is likely that observed improvements in English might be due to English language immersion.

▼ This study investigated information parents of children born prematurely reported that they received about speech and language delays. It examined whether or not children were considered at risk for communication and language delays and whether or not parents were seeking intervention for their children. Children were separated into two categories: Children who passed The Infant/Toddler Checklist for Communication and Language Development (Wetherby and Prizant, 1998) and children who failed the checklist. Comparisons were made between the information parents reported that they received and whether parents were seeking intervention services. For both groups of children, there was not a significant relationship between whether or not parents sought services and whether or not parents reported that they received information about the risks for speech and language delays. The reason for this finding in both groups was that there were a large number of parents who reported that they were not informed of risks and they were not seeking services. The implications of these findings are discussed.

(more)
▼ Since its introduction several years ago, multichannel signal processing has become a nearly ubiquitous component of programmable and digital hearing aids. Rapid development of sophisticated multichannel circuits has proceeded well ahead of sound clinical techniques to implement this new technology. Splitting the incoming acoustic signal into as few as two independent high and low frequency bandpass filters (channels) can provide significant perceptual benefits for some hearing aid wearers but no empirically derived relationship has ever been found between a given set of bandpass filter settings and improved speech perception in noise. More specifically, adjustments to the crossover frequency at which the bandpass filters intersect, has never conclusively been shown to improve speech perception in noise. This might have been because the area of crossover frequency settings in and of itself has never received a great deal of attention. The primary purpose of this study was to determine whether speech perception is significantly affected by changing the crossover frequency of a two-channel hearing aid across different sound environments. Those environmental sounds included: the steady state low frequency engine of a jet in flight, the slowly modulating wideband energy of ocean waves breaking on a beach and the high frequency transient bursts of rain hitting a tin roof. Nine participants were given the Hearing in Noise Test (HINT) and the Four Alternative Auditory Features (FAAF) test in the presence of each environmental sound. They were all tested wearing pairs of two-channel digital hearing aids with the crossover frequency set each of four ways: wideband, 800 Hz, 1600 Hz or 3200 Hz. Statistically significant group differences were found for both the 1600 Hz and 3200 Hz settings over the wideband condition on the HINT in the rain. Comparison of the HINT scores for each of the nine participants indicated that the1600 Hz setting was superior to all others in both the rain and jet sounds. The wideband setting led to the poorest results in the rain and the 800 Hz crossover was poorest in the jet environment. This experiment showed that speech perception is significantly affected by the interaction between crossover frequency settings and listening environments.

(more)
▼ This study obtained normative data for the standardization of the Time Compressed Sentence Test (TCST) (Keith 2002). The TCST is used to identify disorders of auditory timing, referred to as temporal processing disorders and contains a practice subtest, two subtests consisting of 40% time compression, and two subtests consisting of 60% time compression. The TCST was administered to normal typically developing children. This data was imperative to establishing the norms for each subtest for each age group. 117 children between the ages of 6years 0 months and 11 years and 11 months were utilized for this study. Of the 117 subjects, 58 were males and 59 were females. To determine whether there was a significant difference between 40% time compression and 60% time compression, a 1 Within X 1 Between Repeated Measures analysis of variance (ANOVA) was carried out. There was a significant compression effect. A significant age effect was also found across the five groups of children. The ANOVA was also used to test for a Compression X Age interaction. The interaction was found to be significant. A second ANOVA (1 Within X 1 Between) was used to determine if there was a significant difference between the right and left ear scores. There was a significant Ears Main Effect. There was not a significant Ears X Age interaction. In light of the significant Compression main effect and the presence of a significant Age effect, a series of pairwise comparisons were obtained using the Tukey Honestly Significant Difference test. Comparisons were fist obtained across age groups at the 40% and 60% compression levels. It was found that the oldest age group (10-11) performed significantly better than the three youngest age groups (6-8) at 40% compression and that the youngest age group (6 yr) performed significantly worse than the other four groups. All age groups performed more poorly at 60% compression than at 40% compression. In addition, since there was a significant Ear main effect and the presence of a significant Age effect, a series of pairwise comparisons were obtained utilizing the Tukey Honestly Significant Difference Test. Comparisons were obtained across age groups for the right and left ears. It was found that the oldest age group (10-11) performed significantly better than the 6 and 8 year- olds in the Right ear. These comparisons were also obtained for the left ear indicating that the youngest age group (6yr) performed more poorly than the older age groups (7-11).

▼ Objective: Few studies have documented the development of the auditory thalamus. No studies have documented this development in the ferret. The purpose of this study was to document the development of cytoarchitectural structures of the ferret medial geniculate body (MGB). Methods: The MGB of 3 ferrets ages postnatal day 32 (P32), P60, and P77 were serially sectioned using a vibratome. The serial sections were dehydrated, stained using Cresyl Violet, coverslipped, and imaged using Kodak digital science microscopy documentation system (MDS100) connected to an Olympus B50 microscope. Results: The three subjects, P32, P60, and P77, demonstrate the changes that occur in the ferret thalamus from P32 to adult-like P77. The major MGB subdivisions were present in all three animals. However, clear dendritic staining was only found in the youngest ferret P32. Cytoarchitectural structures were found to be similar to adulthood especially in ferret P77. Discussion: Just as in the previous study of MGB development in the rat by Clerici and Coleman (1998), this study reveals that dendritic staining for Nissl does occur in younger animals and only somata stain for Nissl in adult animals. The structures of the auditory thalamus develop similarly to that of the rat. All of the major structures were identified by age P32 in the ferret. Continued growth of the MGB was observed through P77. This study provides information on the development of the ferret auditory thalamus. Due to the fact that the ferret is a useful animal model for studying development of the auditory system, it is important to document the development of the MGB. This information can be used for comparisons in future studies of the ferret auditory system.

▼ This study compared children's actual telephone discourse skills with pretend telephone discourse skills. The purpose of this study was to determine whether pretend telephone use represents actual telephone discourse skills by examining the similarities and differences between actual telephone discourses and pretend telephone discourse. In addition, this study provided information regarding the types and frequencies of pragmatic skills observed during real and pretend telephone conversations. Results indicated that there was no statistical relationship between children's actual and pretend telephone conversation. However, analysis of the quantity and quality of pragmatic skills demonstrated by the subjects provided insight to the nature of children's pretend telephone discourse. This information could be valuable to clinicians who use toy telephones as a tool help evaluate pragmatic skills.

▼ This study investigates the subjective benefits of cochlear implants in children with multiple handicaps according to their primary parent or gaurdian. The study enrolled twenty-one subjects from Cincinnati Children's Hospital Medical Center who have received a cochlear implant and have been diagnosed with at least one disability in addition to hearing loss. Children of all ages, races, and sex were eligible for participation. Participants in this study were notified of the study through their rehabilitation therapist or through letter. An interview time was then set up. At the interview. parents were asked questions from the designed questionnaire. Audiologic and demographic information was collected via chart review for additional analysis. As more children with multiple handicaps are receiving cochlear implants, it is important to better understand the needs of this population as well as the parents' perception of the benefit to provide them the best services and opprotunities to succeed with a cochlear implant. Results of this study and other related research will improve the quality of services and may lead to greater benefits in children with a cochlear implant and multiple handicaps.

▼ This study examines auditory processing abilities of children with severe-to-profound unilateral sensorineural hearing loss. Children typically experience a right ear advantage until auditory maturation occurs during the early stages of adolescence. The objective of this study was to determine if laterality of the hearing loss impacts how auditory stimuli are processed. There were six subjects, 4 males and 2 females, ranging in age from 6 to 13 years. Two subjects had a left ear loss, while 4 subjects had a right ear loss. Each subject had a severe to profound unilateral sensorineural hearing loss, with normal hearing sensitivity and an absence of middle ear pathology in the opposite ear. The peripheral audiologic characteristics of the subjects were determined in the ear with normal hearing sensitivity by standard pure tone audiometry, tympanometry, physical examination, speech recognition thresholds, and distortion product otoacoustic emission testing. Subjects were administered a battery of auditory processing assessments, including Filtered Words, Auditory Figure Ground, Random Gap Detection Test, Pitch Patterns Sequence Test, and Time Compressed Sentence Test. Results are reported in the form of six case studies and performance on the auditory processing battery. Given the limited number of subjects, comparison data is not available. This is an ongoing study, with the intention of acquiring 50 subjects, with an equal distribution of male and female and right verses left ear hearing loss.

▼ The purpose of the present study was to examine the effect of prolonged loud reading, intended to induce fatigue, on vocal function in adults with unilateral vocal fold paralysis (UVFP). Subjects were 20 adults, 37-60 years old, with UVFP secondary to recurrent laryngeal nerve paralysis. Subjects were asked to read continuously for as long and as loud as they could until they felt fatigued and wished to stop. Demographic and etiologic data were collected for each subject. Subjective ratings and instrumental (acoustic, aerodynamic, and videoendoscopic) measures of vocal function were obtained before and after reading. Acoustic and aerodynamic measures were collected for comfortable, high, and low pitches. Statistical analysis revealed subjects rated their vocal quality and physical effort for voicing more severely following prolonged loud reading, whereas expert raters did not detect a significant perceptual difference in vocal quality. Reading fundamental frequency (Fo) was significantly elevated following prolonged loud reading, as were mean airflow rates at all pitch conditions. Maximum phonation times for comfort and low pitches significantly decreased during posttests. Multiple regression analyses revealed significant associations between ratings of posttest physical effort and posttest measures of: reading Fo, low pitch noise to harmonics (N/H) ratio, mean airflow rates, high pitch maximum phonation time, glottic closure, supraglottic compression, and vocal fold edge. A significant association between total minutes read and the posttest acoustic measure of pitch range-lowest end and glottic closure was demonstrated. A multiple correlation analysis revealed no significant correlations between position of the paralyzed vocal fold and posttest ratings of physical effort, total minutes read, gender, or onset of paralysis. Interpretation of results indicates the prolonged loud reading task was successful in vocally fatiguing most of the UVFP subjects. Post-reading vocal fatigue was marked by changes in perceptual and kinesthetic sensations heard and felt by the subjects, as well as changes in instrumental values. Those values suggest that key physiologic correlates of vocal fatigue, in individuals with UVFP, include further reduction of glottic efficiency, resulting in decreased regulation of glottic airflow and a temporary destabilization of speaking fundamental frequency.

▼ Classical voice, music theater singers and actors use their voices in potentially damaging ways. The present study used a survey and personality inventory to differentiate voice use, and determine if personality type influences vocal abuse behaviors. Study results indicate music theater and acting students display a significantly higher amount of vocal abuse behaviors than classical voice students. The personality types of the three groups were similar. Most were extroverted, with idealist and guardian profiles. Areas in which students are successfully avoiding abusive situations and behaviors are discussed, and information to aide voice professionals in improving vocal hygiene education is provided.
