The Role Of Vocal Development Patterns: Predicting Neurogenetic Risk In Infancy Using Early Vocal Development And Sex, Alyssa Cregg, Rachel Siela, Olivia Battaglia, Kaylee Bobay, Madison Chin, Athena Fordwor, Conghao Gao, Deeksha Handa, Erin Lee, Tiernan Mcdivitt, Grace Strabala, Victoria Tuell, Laurel Williams

The Journal of Purdue Undergraduate Research

Extant literature documents a higher rate of language/speech disorders in males; however, despite sex being a potential moderator of outcomes, we do not know what role it plays in early vocal behavior of infants at high risk for such disorders. The purpose of this study was to ask: (1) Do high-risk infants demonstrate atypical vocal development patterns? (2) Is the quality and quantity of early babble distinct for male and female infants, and does this pattern vary across risk? To answer these questions, we examined the canonical babbling ratio (CBR; the ratio of canonical syllables, those with a consonant and …

Developing A Drug Delivery System For Treatment Of Vocal Fold Scarring, Aaron Michael Kosinski

Open Access Dissertations

Vocal fold scarring is an affliction that results in the formation of a disorganized and stiff extracellular matrix (ECM) with abnormal ECM component densities & structures including a significant increase in collagen deposition. It is caused by improper healing post injury and results in profound changes in the biomechanical properties of the vocal folds impairing their ability to generate a normal mucosal wave during phonation.

Finding an effective treatment for vocal fold scarring has been elusive. Currently, treatments seek temporary solutions that correct glottal incompetence and reduce stiffness caused by the scar through the augmentation of the vocal folds using …

Predicting Language Impairment Status: A Risk Factor Model, Johanna Maria Rudolph

Open Access Dissertations

The etiology of specific language impairment (SLI) is multifactorial. Research has shown that genetic, environmental, and developmental factors may influence the course of its development. Because many of these factors are present even before a child is born, it is possible that a child's risk of developing the disorder can be identified long before grammatical deficits are observed. The goal of this study was to develop and validate a screening tool to discriminate between children with SLI and typically developing (TD) children using risk factor information including gender, family history of communication or reading disorders, socioeconomic status, maternal and paternal …

Age-Related Changes To The Production Of Linguistic Prosody, Daniel Richard Barnes

Open Access Theses

The production of speech prosody (the rhythm, pausing, and intonation associated with natural speech) is critical to effective communication. The current study investigated the impact of age-related changes to physiology and cognition in relation to the production of two types of linguistic prosody: lexical stress and the disambiguation of syntactically ambiguous utterances. Analyses of the acoustic correlates of stress: speech intensity (or sound-pressure level; SPL), fundamental frequency (F0), key word/phrase duration, and pause duration revealed that both young and older adults effectively use these acoustic features to signal linguistic prosody, although the relative weighting of cues differed by group. Differences …

Preschool Language And Phonological Proficiencies In Predicting Stuttering Recovery Or Persistence, Caroline E. Spencer

Open Access Theses

The purpose of this study was to investigate the relationship between expressive and receptive language, phonological, and verbal working memory proficiencies in the preschool years and eventual recovery from or persistence in stuttering. Participants included 40 children who stutter (CWS). At ages 3-5 years, participants were administered the Test of Auditory Comprehension of Language, 3rd edition (TACL-3), the Structured Photographic Expressive Language Test, 3rd edition (SPELT-3), Bankson-Bernthal Test of Phonology--Consonant Inventory subtest (BBTOP--CI), Test of Auditory Perceptual Skills--Revised (TAPS--R) auditory number memory and auditory word memory subtests, and the Dollaghan & Campbell Nonword Repetition Test (NRT). Stuttering behaviors were tracked …
