Barrett, The Honors College Thesis/Creative Project Collection


Barrett, the Honors College accepts high performing, academically engaged students and works with them in collaboration with all of the other academic units at Arizona State University. All Barrett students complete a thesis or creative project, supervised and defended in front of a faculty committee. The thesis or creative project allows students to explore an intellectual interest and produce an original piece of scholarly research. The thesis or creative project is a student’s opportunity to explore areas of academic interest with greater intensity than is possible in a single course. It is also an opportunity to engage with professors, nationally recognized in their fields and specifically interested and committed to working with honors students. This work provides tangible evidence of a student’s research, writing and creative skills to graduate schools and/or prospective employers.

The increase of Traumatic Brain Injury (TBI) cases in recent war history has increased the urgency of research regarding how veterans are affected by TBIs. The purpose of this study was to evaluate the effects of TBI on speech recognition in noise. The AzBio Sentence Test was completed for signal-to-noise ratios (S/N) from -10 dB to +15 dB for a control group of ten participants and one US military veteran with history of service-connected TBI. All participants had normal hearing sensitivity defined as thresholds of 20 dB or better at frequencies from 250-8000 Hz in addition to having tympanograms within ...

Preschoolers’ vocabularies are an important component of their receptive and expressive language skills. This study was designed to catalog preschoolers’ expressive vocabularies to provide an accurate estimate of how many words and which words seven preschoolers knew. In this study a LENA digital recorder was used to record language samples of the children (age range 40 months to 69 months) over 4-6 days. Their language samples were transcribed and individual root words were extracted. The children spoke an average of 1,698 unique words (range 1,522 – 1,957 words). There were 539 words produced by all of the children in the ...

The purpose of this research is to investigate the types of play and the use of play within daily routines that early intervention providers, parents of children with disabilities, and parents of typically developing children use with children under the age of three. It is important to research the current use of play by parents and providers to explore how play can be used most effectively to help children learn in other developmental domains. Two online surveys were created and distributed, one for early intervention providers and one for parents. The data from the surveys suggests early intervention providers and ...

This thesis compared two measures of phonological assessment of children, Shriberg and Kwiatkowski’s 1980 Percentage of Correct Consonants (PCC) and Ingram’s 2002 Proportion of Whole Word Proximity (PWP). Two typically developing two-year-old children were initially studied, and then nine children with speech sound disorders. The children’s words were divided into four categories ranging from least complex to most complex. It was hypothesized that the measures would correlate with word simplicity. The hypothesis was supported for the two typically developing children, and for five of the children with speech sound disorders. The other four children with speech disorders, however, did not ...

Research on /r/ production previously used formant analysis as the primary acoustic analysis, with particular focus on the low third formant in the speech signal. Prior imaging of speech used X-Ray, MRI, and electromagnetic midsagittal articulometer systems. More recently, the signal processing technique of Mel-log spectral plots has been used to study /r/ production in children and female adults. Ultrasound imaging of the tongue also has been used to image the tongue during speech production in both clinical and research settings. The current study attempts to describe /r/ production in three different allophonic contexts; vocalic, prevocalic, and postvocalic positions. Ultrasound ...

The purpose of this study was to explore the effects of word type, phonotactic probability, word frequency, and neighborhood density on the vocabularies of children with mild-to-moderate hearing loss compared to children with normal hearing. This was done by assigning values for these parameters to each test item on the Peabody Picture Vocabulary Test (Version III, Form B) to quantify and characterize the performance of children with hearing loss relative to that of children with normal hearing. It was expected that PPVT IIIB scores would: 1) Decrease as the degree of hearing loss increased. 2) Increase as a function of ...

The objective of this study was to examine the universality of three coarticulatory processes: glide epenthesis, stop epenthesis, and intervocalic voicing of stops. Five contrastive languages were selected to test these processes. These languages included English, Spanish, Mandarin, Arabic, and Navajo. All languages varied in phonemic inventory, stress patterns, phonological processes, and syllabic constructs. 16 participants were selected with relatively limited English exposure based on questionnaire responses regarding their language history. The participants went through a series of trainings and tasks to elicit these coarticulatory processes in several phonemic contexts. Part 1 of the study attempted to elicit the processes ...

Working memory and cognitive functions contribute to speech recognition in normal hearing and hearing impaired listeners. In this study, auditory and cognitive functions are measured in young adult normal hearing, elderly normal hearing, and elderly cochlear implant subjects. The effects of age and hearing on the different measures are investigated. The correlations between auditory/cognitive functions and speech/music recognition are examined. The results may demonstrate which factors can better explain the variable performance across elderly cochlear implant users.

The manner in which plants are able to acquire plant nitrate (NO3-) varies depending on a combination of distinct processes between “root high-and low-affinity NO-3 transporters and the proton gradient that is generated by the plasma membrane H+-ATPase” (Paez-Valencia et al, 2013). In this study we analyzed the response to limiting nitrate (0.5 mM) of seventy-four breeding lettuce (Lactuca sativa) lines derived from the cross Parade vs. Pavane. Parade had an enhanced root acidification capacity when grown under Nitrate limitation in comparison to Pavane, which had a poor root acidification capacity. Two successive experiments were conducted under distinct environmental conditions ...
