Similarities And Difference In The Neural Processing Of Speech And Song In Religious Music, Brett Pielstick
Similarities And Difference In The Neural Processing Of Speech And Song In Religious Music, Brett Pielstick
Undergraduate Honors Theses
An fMRI study was performed to see the differences in the neurological processing between spoken and sung language in religious music. Students at Brigham Young University, who are members of the Church of Jesus Christ of Latter-day Saints, were exposed to alternating blocks of spoken and sung lyrics of religious and non-religious songs. There was no significant activation when contrasting speech and song, but there was significant activation in the right middle temporal gyrus and the posterior cingulate gyrus when listening to spoken and sung religious lyrics, suggesting an emotional reaction to religious stimuli. Contrasting spoken stimuli for both religious …
Effects Of Syntactic Complexity On Speech Motor Performance, Kelsey Lewis Boyce
Effects Of Syntactic Complexity On Speech Motor Performance, Kelsey Lewis Boyce
Theses and Dissertations
This study evaluated the possible influence of linguistic demands on speech motor control by measuring articulatory movement stability during conditions of increasing grammatical complexity. There were 60 participants in three age groups: 20-30 years, 40-50 years, and 60-70 years, with equal numbers of men and women in each group. These speakers produced 10 repetitions of five different sentence or phrase conditions. These five conditions included two baseline measurements and three sentences of varying complexity. Each complexity condition had an MLU count of 23, word length of 17, syllable length of 25, and contained the phrase open boxes of pompoms. …
The Effects Of Intensive Lower Limb Training On The Speech Of Patients With Parkinson's Disease, Lauren Fjeldsted Allen
The Effects Of Intensive Lower Limb Training On The Speech Of Patients With Parkinson's Disease, Lauren Fjeldsted Allen
Theses and Dissertations
Research has documented the positive effects of physical therapy as a treatment for limb motor symptoms associated with Parkinson's disease (PD). Previous studies have shown that speech and voice measures can be reflective of overall cardiovascular health and fitness in young, middle-aged, and older adults. In healthy individuals, increased respiratory drive has been found to influence vocal function and speech articulation. The rationale for the present study was that improved lower limb function might lead to improvements in overall fitness, which then may influence speech in individuals with Parkinson's disease. To investigate this premise, 10 participants diagnosed with mild to …
The Effects Of Task Preference On Speech And Motor Performance Under Divided Attention Conditions, Amy Sue Leiter
The Effects Of Task Preference On Speech And Motor Performance Under Divided Attention Conditions, Amy Sue Leiter
Theses and Dissertations
Dual task performance and the interaction of tasks has been the subject of much research. When tasks are performed together they affect each other to varying degrees depending upon such factors as the similarity of the tasks, their difficulty, and whether one task is given preference over another. In this study, task preference was investigated under divided attention conditions in order to determine what effect preference had on task performance. Twenty young adults took part in this study and were randomly assigned into two groups. Each group was experimentally motivated to favor one of the two tasks – either speaking …
Effects Of Delayed Auditory Feedback On The Bereitschaftspotential, Jennifer L. Johnson
Effects Of Delayed Auditory Feedback On The Bereitschaftspotential, Jennifer L. Johnson
Theses and Dissertations
This study examined the brain electrical activity of normal speakers in a non-delayed auditory feedback (DAF) condition and when experiencing DAF to determine the effect DAF would have on the Bereitschaftspotential (BP). The BP reflects the preparatory state of a person prior to motor execution of an act and can be observed 1500 to 500 ms prior to voluntary movement. The participants in the study included 10 adults with normal speech. Each read a series of 30 sentences, both without DAF and with DAF, while the BP was measured. Results indicate that the BP is present across the scalp in …
How Individuals With Parkinson's Disease Modify Their Speech In A Repetition For Clarification, Lynn Marie Watkins
How Individuals With Parkinson's Disease Modify Their Speech In A Repetition For Clarification, Lynn Marie Watkins
Theses and Dissertations
The speech of individuals with Parkinson's disease (PD) is typically characterized as lacking in proper prosody because of its monopitch and monoloud quality, in addition to its reduced intensity. These qualities make it difficult for others to understand speakers with PD. The purpose of the current study was to identify what individuals with PD would do vocally, if anything at all, to improve speech production following a simulated misunderstanding of what they had just said. The study evaluated the performance of 5 individuals with PD and compared their performance to 5 age- and sex-matched controls. Specifically, measures of vocal intensity …
Exploration Of Lip Shape Measures And Their Association With Tongue Contact Patterns, Jessica Lynn Wagner
Exploration Of Lip Shape Measures And Their Association With Tongue Contact Patterns, Jessica Lynn Wagner
Theses and Dissertations
A variety of tools and techniques have been developed to measure the movements of the vocal tract, specifically of the tongue and lips. In recent years, computer technology has allowed for extensive exploration of these precise movements and for the development of speech recognition systems. However, there has been relatively little work on the combination of visible facial movements and internal articulatory activity. In this study, two different technologies were used to explore the internal and external movements of speech production in eight speakers: palatometry quantified tongue contact patterns and computerized video image analysis was used to derive lip shape …
