Common Parietal Activation In Musical Mental Transformations Across Pitch And Time, Nicholas E.V. Foster, Andrea R. Halpern, Robert J. Zatorre

Faculty Journal Articles

We previously observed that mental manipulation of the pitch level or temporal organization of melodies results in functional activation in the human intraparietal sulcus (IPS), a region also associated with visuospatial transformation and numerical calculation. Two outstanding questions about these musical transformations are whether pitch and time depend on separate or common processing in IPS, and whether IPS recruitment in melodic tasks varies depending upon the degree of transformation required (as it does in mental rotation). In the present study we sought to answer these questions by applying functional magnetic resonance imaging while musicians performed closely matched mental transposition (pitch …

Analysing A New Mobile Bilateral Audiology Test For Children, Luke J. Brook

Theses : Honours

Hearing loss in Australian children, primarily Aboriginal and Torres Strait Islanders, is a growing concern for the Australian public health sector. In certain rural communities up to 90 per cent of children have been found to experience some form of hearing loss. Although hearing loss can be the result of a number of different causes, including congenital influences, the most common cause of hearing loss in Australian children is attributed to a common middle ear infection, otitis media.

To address the issue, numerous solutions have been proposed, tested and implemented, although the problem persists due to geographic, environmental and cultural …

The Use Of The Communication Checklist - Adult (Cc-A) For Assessing The Communication Abilities Of Individuals Post Traumatic Brain Injury, David B. Fitzgerald

Theses : Honours

Background and aims: Standardised and non-standardised assessments are used in speech pathology to evaluate an individual’s communication abilities post traumatic brain injury (TBI; e.g. Turkstra et al., 2005b). However, valid, reliable and norm-referenced standardised assessments that examine functional communication abilities of individuals post TBI outside of the clinical environment are limited. This study sought to investigate the validity of the Communication Checklist - Adults (CC-A; Whitehouse & Bishop, 2009), a caregiver questionnaire that assesses the communication abilities of individuals post TBI.

Method: The project recruited 14 participants post TBI with varying communicative impairment severities. Each participant completed a routine communication …

Experiences Of Speech-Language Pathology Graduate Students: An Exploratory Phenomenological Study, Anysia J. Ensslen

Theses and Dissertations--Educational Leadership Studies

Within the past decade little research has been conducted in the United States to examine the preparedness of beginning speech-language pathologists; the seminal article used for this research study comes from the United Kingdom (Horton, Byng, Bunning, & Pring, 2004). Literature from the past few decades indicates that there may be deficiencies in the way that beginning speech-language pathologists are being trained clinically.

The review of the literature suggests that the field may lack a clear and broadly supported learning theory or framework for the clinical supervision and training of speech-language pathology graduate students. The literature further supports the importance …

Effects Of Speech Production Ability On A Measure Of Speech Perception Capacity In Young Children With Cochlear Implants And Their Articulation-Matched Peers, Victoria Beatriz Gonzalez

USF Tampa Graduate Theses and Dissertations

With reductions in the age criterion for cochlear implantation, the need for age-appropriate measures of speech perception skills has increased. One recently developed tool that shows great promise for the clinical assessment of auditory speech perception capacity in young children with cochlear implants is the On-Line Imitative Test of Speech-Pattern Contrast Perception (OlimSpac). The OlimSpac requires a child to imitate nonword utterances by providing a verbal response. The child's perceptual abilities are inferred from the child's productions through having a listener, who is masked to the stimulus select the utterance produced by the child in an eight-alternative force-choice task. Although …

The Effect Of Timbre And Vibrato On Vocal Pitch Matching Accuracy, Sirisha Duvvuru

Theses and Dissertations (ETD)

Research has shown that singers are better able to match pitch when the target stimulus has a timbre close to their own voice. This study seeks to answer the following questions: 1. Do classically trained female singers more accurately match pitch when the target stimulus is more similar to their own timbre? 2. Does the ability to match pitch vary with increasing pitch? 3. Does the ability to match pitch differ depending on whether the target stimulus is produced with or without vibrato? 4. Are mezzo sopranos less accurate than sopranos?

Improving Literacy Through Instruction And Community Experiences: : The Effect Of A Summer Program On Literacy Outcomes Of Students From Low Ses Homes, Lisa Delozier Bowers

Theses and Dissertations (ETD)

Among the academic challenges faced by students from low socio-economic (SES) homes is the loss of academic skills during the summer months. Unfortunately, the public schools are often unable to provide summer learning opportunities because limited space, funding, and teacher availability. Established community organizations frequently provide summer programs, however, there is little research to indicate that they can be used to address summer learning loss.

A summer program was designed to improve oral and written narrative skills for students from low SES homes. This program was based in a local community ministry and was designed to use thematic units that …

Independent Component Analysis Of Event-Related Electroencephalography During Speech And Non-Speech Discrimination: : Implications For The Sensorimotor ∆∞ Rhythm In Speech Processing, Andrew Lee Bowers

Theses and Dissertations (ETD)

Background: The functional significance of sensorimotor integration in acoustic speech processing is unclear despite more than three decades of neuroimaging research. Constructivist theories have long speculated that listeners make predictions about articulatory goals functioning to weight sensory analysis toward expected acoustic features (e.g. analysis-by-synthesis; internal models). Direct-realist accounts posit that sensorimotor integration is achieved via a direct match between incoming acoustic cues and articulatory gestures. A method capable of favoring one account over the other requires an ongoing, high-temporal resolution measure of sensorimotor cortical activity prior to and following acoustic input. Although scalp-recorded electroencephalography (EEG) provides a measure of cortical …

Efficacy was assessed by number of: verbalizations, correct words, words reported by parent, and imitative attempts. Additionally it examines the effect of exposure to MBCT on social language abilities as measured by score on the Pragmatic Language Skills Inventory (PLSI); the effect of age on the response to treatment, and the predictors of overall effectiveness of treatment. Participants were 12 nonverbal children with autism ages 5 through 7 randomly assigned …

Intelligibility And The Sinewave Speech Carrier Phrase Effect, Danielle R. Werle

Honors Theses

Several studies have examined the perception of sinewave speech. Early work showed that listeners could transcribe sinewave sentences. Recent work on sinewave vowels found that listeners could recognize sinewave speech at the phonetic level with moderate (about 50-55%) accuracy. Sinewave vowel intelligibility scores improve significantly when preceded by a sinewave carrier phrase, an effect that disappears when the carrier phrase is removed. The present study was designed to examine this carrier phrase enhancement effect and analyze whether listeners require the carrier phrase to be intelligible to produce increased intelligibility scores. Sinusoidal carrier phrases and /hVd/ syllables were generated from recordings …

Spatiotemporal Coupling Of The Tongue In Amyotrophic Lateral Sclerosis, Mili S. Kuruvilla, Jordan R. Green, Yana Yunusova, Kathy Hanford

Department of Special Education and Communication Disorders: Faculty Publications

Purpose: The primary aim of the investigation was to identify deficits in spatiotemporal coupling between tongue regions in amyotrophic lateral sclerosis (ALS). The relations between disease-related changes in tongue movement patterns and speech intelligibility were also determined.

Methods: The authors recorded word productions from 11 individuals with ALS with mild, moderate, and severe dysarthria using an x-ray microbeam during word productions. A coupling index based on sliding window covariance was used to determine disease-related changes in the coupling between the tongue regions across each word.

Results: The results indicated decreased spatiotemporal coupling of mid-posterior tongue regions and reduced tongue speed …

Spontaneous Recovery In Children With Expressive Language Delay, Jaimie Sierakowski

Honors Theses

By age 2, most children have an expressive vocabulary of approximately 200 words and begin to combine these words into meaningful phrases. However, some children acquire expressive language skills more slowly than others while displaying no signs of cognitive, receptive, or sensory delays. These children who experience an expressive language delay are often characterized in the literature as late talkers. Research shows that many of these children have delays early in childhood, but eventually catch up to their typically-developing peers, with no need for language intervention. Others, however, continue to experience expressive delays and. have an increased risk of developing …

Nonword Repetition And Interactions Among Vocabulary, Phonotactic Probability, And Phonological Awareness In Four Linguistic Groups, Sue Ann S. Lee, Brenda K. Gorman

Speech Pathology and Audiology Faculty Research and Publications

The current study was designed to compare the English nonword repetition accuracy in 7-year-old monolingual English, Korean–English bilingual, Chinese–English bilingual, and Spanish–English bilingual children. The relationships among nonword repetition accuracy, vocabulary, phonological awareness, and phonotactic probability in each group of children were also examined. The results indicated significant differences among the groups’ accuracy of consonants and vowels by syllable length. Different correlational patterns emerged among nonword repetition accuracy, vocabulary, and phonological awareness. Theoretical and clinical implications for the use of nonword repetition tasks for children from various linguistic backgrounds are discussed.
