Seventeen high school students with learning disabilities and 17 normal-achieving high school students participated in this study. Twenty scenes were presented verbally to the participants who were instructed to act out the part of a character in each scene, making up the dialogue to fit the scene. The responses were scored for their pragmatic appropriateness and linguistic quality. Task reliability and validity analyses indicated that the dramatization task was an effective measure of key aspects of pragmatic skills. …

Impact Of Amateur Educational Video Viewing On Language Acquisition Of Preschool Children, Jennifer L. Radcliffe

Masters Theses

Child language-learning is a complex process that varies for each individual child. Researchers have found that children learn from viewing professional television programs specifically designed for children, such as Sesame Street. Professional television programming principles can be adopted to produce amateur educational videos. Video may also be a viable option to provide repetitive models to improve vocabulary acquisition within speech-language pathology. The purpose of this study was to measure the effect of direct stimulation with amateur educational videos on a child's general and specific vocabulary acquisition.

A six-week experiment included an initial two-week control period, a two-week experimental period …

Speech-Language Pathologists' Opinions Of The Reliability Of The Modified Evan's Blue Dye Test For Detecting Aspiration, Amy N. Sanders

The Effects Of Interactive Songs On Syllable Production In A Child With Agenesis Of The Corpus Callosum, Kelly D. Beens

Masters Theses

Agenesis of the corpus callosum is a disorder which has been the focus of clinical research on various tasks involving interhemispheric transfer of information. However, therapeutic intervention for individuals with this disorder has not been located in the literature by this researcher. Speech-language therapy for a five-year-old male incorporating interaction with songs was employed to activate various portions of the congenitally separated cerebral hemispheres and to encourage information transfer through non-traditional ways to facilitate syllable production.

The child received speech-language therapy for 15, 30-minute sessions. He was prompted to participate physically (with actions or manipulation of props) and verbally in …

Investigation Of The Relationship Between Language & Mathematics In Regards To Problem Solving, Heather A. Grant

Masters Theses

While previous research has established language as a component of mathematical performance (Kintsch, 1988; Simon, 1985), none have identified a relationship between language and mathematics. This study was conducted to examine the relationships between language and mathematical abilities, specifically problem solving abilities and concept knowledge.

The subjects consisted of 29 fifth-grade students selected from an elementary school in central Illinois. These students were not receiving special education services. Each subject was administered the Test of Problem Solving (Zachman, et al., 1984) to assess the subjects' ability to utilize reasoning skills and expressive language to solve situational problems; and The WORD …

The Prevalence Of Developmental Apraxia In School-Aged Children Of Illinois, Mary Jo Seibert

Masters Theses

Current research involving developmental apraxia of speech has focused on two areas: 1) determining a unique set of speech and language characteristics of the disorder; and 2) determining an etiology or cause of developmental apraxia. Failure of researchers to determine these issues has lead to increased controversy over the existence of developmental apraxia. Further, no studies have been conducted which discuss the prevalence of developmental apraxia. This researcher suggests that determining the prevalence of developmental apraxia would assist in establishing the disorders' existence, as well as aid researchers in determining if speech-language pathologists have adequate training and knowledge in the …

Language Abilities Of Male Adolescents In A Juvenile Detention Center, Krista J. Klein

Masters Theses

This study was designed to analyze the language abilities of male adolescents with delinquent behavior. It was based on the hypothesis that male adolescents with delinquent behavior would have lower language skills during expressive language tasks. Language skills of male adolescents in a juvenile detention center were examined by comparing 12 grammatical variables, four subtest scores, and one total score from the Screening Test for Adolescent Language (STAL; Prather, Ausdal-Breecher, Stafford & Wallace, 1980). Results indicated that the adolescents with delinquent behavior omitted significantly more words, but also produced significantly more secondary verbs in a narration task. Significantly lower results …

Language Skills Of Adolescents With Emotional Disorders, Diane T. Hardy

The Effects Of Knowledge Of Accrued Clinical Clock Hours On Supervisors' Evaluations Of Clinical Competence, Julie Ann Johnston-Palmer

Masters Theses

Supervision in speech-language pathology is one facet of the field in which all speech-language pathologists have had to engage. The more that is known about the process of supervision the better future speech-language pathologists can be prepared to interact in a professional setting. Many variables are present in supervision related to the field of speech-language pathology. One variable which has received only minimal attention relates to the effect knowledge about a student clinician's number of accrued clinical clock hours has on the evaluation of the clinician's skills. The assumption is often made that a student clinician with more clinical clock …

Acoustic And Perceptual Correlates Of Breathy Vocal Quality, Ronald Allen Cleveland

Masters Theses

Recordings were made of seven normal female and eight normal male talkers producing sustained vowels under normal, moderately breathy, and very breathy conditions. Twenty listeners judged the recorded vowel tokens for degree of breathiness using a direct magnitude estimation procedure. A Cronbach coefficient alpha revealed strong intrasubject agreement.

Several acoustic analyses were evaluated by measuring their correlations with the mean of the listeners' breathiness ratings. Measures of cepstral peak prominence in band limited signals were most strongly correlated with perceived breathiness. The height of the autocorrelation peak in highpass filtered signals and the relative amplitude of the first harmonic were …

Acoustic Characteristics Of Vowels Produced By Men, Women And Children, Laura Arlene Getty

Masters Theses

This investigation was a replication and extension of Peterson and Barney’s (1952) research on the acoustics and perception of vowels. This study explored the acoustic characteristics of 12 vowels produced by 50 men, 50 women and 41 children. Speech samples were tape recorded as subjects read lists of words and isolated vowels. Speech samples were digitized. Speech waveforms, spectrograms and formant frequencies were examined and measured.

The average formant frequency values were similar but not identical to the values reported by Peterson and Barney (1952). The largest discrepancy between the two studies was the degree of overlap among vowel categories, …

Perceptual Effects Of Perturbation And Additive Noise, Richard E. Nero

Masters Theses

This study investigated the perceptual effects of varying glottal waveshape perturbation, duty cycle perturbation, jitter, signal-to-noise ratio perturbation, and shimmer at three levels of perceived magnitude (high, medium, and low). Voice signals were synthesized using a modified version of Klatt's (1980) formant synthesizer. Listeners rated signal dysphonia using an A-B dissimilarity procedure. Multidimensional scaling analysis suggested that signals judged low in magnitude of dysphonia were perceived to be most similar. Medium-level and high-level magnitude signals were judged to be respectively less similar. Signals varying in duty cycle and fundamental frequency perturbation were perceived to be very similar while those signals …

Analogical Reasoning Of Elderly Adults Using Three Modalities: Words, Pictures, And Figures, Judy L. Rau

Masters Theses

This study examined the analogical processing skills of elderly adults. Forty-seven subjects (ages 65-90) completed analogy tasks presented in three modalities: words, pictures, and geometric figures (90 total). The subjects for this study were elderly adults living independently in a federally subsidized apartment building. The subjects used in this study possessed characteristics similar to the "typical" American adult. Results indicated that performance does not vary significantly with age in the word and picture modalities. Significant (p < .05) negative relationships were found between performance on the geometric figure analogies and increased age and between overall performance and increased age. Significant (p < .05) positive relationships were found between education and performance on each of the three modalities as well as between education and overall performance.

Effects Of Intervention On The Ability Of Students With Hearing Impairments To Write Personal Narrative Stories, Beth L. Miller

Masters Theses

This study was designed to determine whether students with hearing impairments could be taught to write more mature personal narrative stories. An experimental group of junior high students received intervention focused on teaching the elements of story grammar and their application to the students' written narrative stories. A matched control group of students spent equal time with the researcher and received intervention focused on improvement of basic language skills. Pretest, posttest-1, posttest-2, and generalization samples were taken. Students' metatextual skills for telling how to write a story were also probed.

A significant difference was found between the experimental and control …

The Effects Of Unilateral Brain Damage On Analogical Reasoning By Stroke Patients, Letitia Lynn Gillespie

Masters Theses

It is the purpose of this study to provide a descriptive analysis of 13 patients who have undergone a modified pharyngeal flap surgery completed by one plastic surgeon. Variables associated with the speech of these individuals were based on four measures, including a questionnaire, the Iowa Pressure Articulation Test, the screening portion of the Templin-Darley Test of Articulation, and listener ratings of audio-taped post-surgical speech samples.

Of the eight subject variables studied, two variables were found to be closely associated with speech results. These variables included number of surgeries performed on subjects and number of years in speech therapy. The …

Reliability And Validity Of The Black English Sentence Scoring System, Yvette D. Hyter

Masters Theses

The purpose of this study was to assess the concurrent validity and interscorer reliability of a specific diagnostic tool of language assessment which is designed to be nonbiased for dialectally different children. Black English Sentence Scoring (BESS; Nelson, 1983), which is based on Lee's (1974) Developmental Sentence Scoring (DSS), is a system for analyzing spontaneous language samples that gives cred it for the normally developing features of Black English dialect. The sample consisted of 17 children between three and seven years who were residing in Michigan in communities where Black English was spoken frequently. All were identified as having language …

Rhythmicity, Rate, And Perceived Effort Level Of Fluent And Disfluent Children And Their Parents, Lorraine Destefano Proctor

Masters Theses

Finger tapping and CVC syllable repetition measures of 7 four to eight year old fluent and disfluent children and their mothers were evaluated. Perceptual ratings of speech rate and effort level were also completed by the children, their mothers, and nine graduate students. These procedures were used to test hypotheses that mean interval durations for tapping and for speech, and perceptual ratings of speech rate and effort level are individual in nature.

Results indicated that the subjects1 measures of mean interval durations for tapping and for speech as estimates of rhythmicity, and perceptual ratings of speech rate and effort level …

Mothers' Intervention Strategies In A Structured Question-Answer Dialogue, Marcia C. Hill

Masters Theses

Language intervention strategies of the mothers of ten normal and ten language-impaired children were compared. An experimenter asked each child questions of varying difficulty about a storybook, in the presence of the mother, who was free to help her child as needed. Both the children's and mothers' utterances were coded. The frequency and types of mothers' strategies were analyzed. The analysis revealed that mothers of normal children intervened significantly more often than mothers of language -impaired children, when all interventions were considered. However, the differences were not significant when only interventions related directly to the predetermined questions were considered. The …

Comparison Of Sentence Completion Procedures For The Elicitation Of Copula And Auxiliary Verb Forms From Three-Year-Old Children, Teresa Ann Muchmore

Masters Theses

Speech pathologists have several formal diagnostic methods available for the analysis of language. A diagnostician may elect to use a non-standardized procedure to supplement formal methods. A clinician-designed procedure can facilitate the transition from test result to treatment plan. Such a procedure may be constructed to account for an individual child's age, strengths, and weaknesses. Previous research has indicated that two types of sentence completion tasks, syntactic elicitation and emphatic elicitation, are effective in the elicitation of copula and auxiliary forms of TO BE from kindergarten children. The purpose of this study was to compare the use of these two …

A Hearing Assessment Using Operant Audiological Testing With A Severely Retarded Deaf-Blind Child, Patricia Timpson

Masters Theses

This study assessed the feasibility of teaching a 7-year-old severely retarded, hearing and vision impaired girl to respond consistently to a pure tone stimulus using operant audiometric techniques. The experimenter first shaped a head turn response using the opportunity to rock on a rocking horse as reinforcement. Following response shaping, the experimenter used a bone conduction transducer (BCT) as a tactile stimulus in training the subject to turn her head to the left in a similar fashion to a 500 Hz, 65 dB tone/vibration. After 15 days of transfer training, designed to bring the left head turn response under control …

Magnitude Estimation Of The Quality And Intelligibility Of Degraded Speech, Theresa Smith

Masters Theses

The purpose of the study was to identify within-group and between-group differences in perceived quality and perceived intelligibility of degraded speech for listeners with normal and impaired hearing. Following a visual magnitude estimation task, 10 subjects with normal hearing and 10 subjects with sensory-neural hearing impairment listened to connected speech samples degraded by seven levels of harmonic distortion and estimated the magnitude of their quality and intelligibility. Log average quality estimates and log average intelligibility estimates varied linearly with log degradation values for each group. The slopes of the log-log functions were interpreted as measures of perceptual sensitivity. Slopes for …

A Comparison Of Overall Verb Complexity Between Aphasic Adults And Language Disordered Children, Cheri Suzanne Carrico

Masters Theses

In this investigation, no difference in the overall complexity of verbs produced in spontaneous speech existed between adults and children with primarily expressive language disorders. Six adults, four males and two females between 37;1 and 68;7 years of age, and eight children, five males and three females between 4;3 and 8;3 years of age, comprised the subjects. Each had essentially intact receptive language skills, but was deficient in expressive language abilities. None evidenced a history of hearing, mental or emotional deficits.

Spontaneous language samples elicited from each subject were scored using the Developmental Sentence Scoring (DSS) procedure (Lee, 1974). Marginal, …

The Use Of Thorsen’S Primary Individual Language Screening Test As A Language Assessment Tool, Susan K. Sanders

Masters Theses

An attempt was made to establish Thorsen's Primary Individual Language Screening Test (PILS) as a valid instrument for screening child language by comparing performance of a kindergarten population on the PILS and the Carrow Test of Auditory Comprehension of Language (TACL). Seventy-five subjects were administered both tests and correlational data was analyzed. If a statistically significant relationship existed, then one could assume that a score on the PILS would predict how one would do on the TACL. Test-retest reliability and intra- and inter-examiner reliability were examined. Discriptive statistical characteristics of the PILS scores and TACL scores were obtained for the …
