The Right Ear Advantage In Response To Levels Of Linguistic Complexity: A Functional Magnetic Resonance Imaging Study, Elizabeth Hyatt

Theses and Dissertations

The right ear advantage (REA) phenomenon has been utilized in clinical and research settings to study auditory processing disorders and linguistic lateralization. Previous research has established that the REA is not reliable in its measures within or between individuals. This is likely due to the influence of other variables, such as neuromaturation and attention. One variable that has not been studied in depth in this context is linguistic complexity. It was hypothesized that stimulus conditions with levels of linguistic complexity would elicit corresponding levels of temporal lobe activity. Understanding and controlling the variables that affect the REA will increase the …

Story Generation In Five School-Aged Children With Language Impairment, Suzanne Tutt Jones

Theses and Dissertations

This project examined the story generations of five children with language impairment (LI) between the ages of 5;11 and 10;1 across the treatment sessions of a narrative-based intervention program designed to improve social communication. These stories were analyzed to find whether the participants would approach the task by describing the stimulus pictures or if their stories would reflect an episodic structure containing cause and effect relationships. Additionally, the stories were analyzed for inclusion of emotion words to discern the participants' awareness of the characters' emotions. There was a high degree of variability in the participants' performance; however, the majority of …

Changes In Acoustic And Kinematic Articulatory Working Space Across Three Intensity Levels, Panika Ellis Palmer

Theses and Dissertations

The purpose of this study was to compare changes in acoustic and kinematic measures of articulation across soft, comfortable, and loud speech conditions. There were 19 participants, 9 male and 10 female, with age ranging from 20 to 34 with a median age of 25. Each participant had electromagnetic sensors glued to their tongue, jaw, and lips. It was anticipated that the acoustic measures would accurately reflect the kinematic measures of speech as articulation changed across the intensity levels. Vowel space area (VSA) and vowel articulation index (VAI) were computed from the three corner vowels, /α, i, u/. Articulatory-acoustic vowel …

Previous studies have looked at the effectiveness of using SEEL with other young children with diverse backgrounds; however, this is the first study to focus on using SEEL intervention with children with ASD. The study used a single-subject, multiple-baseline-across-behaviors design to compare performance on phonic patterns before and after intervention. Three young, male …

Neurophysiological Correlates Of The Critical Bandwidth In The Human Auditory System, Grace Ann Bentley

Theses and Dissertations

The critical bandwidth (CBW) is an auditory phenomenon that has been used to study various aspects of auditory processing, including auditory masking, complex tone processing, and loudness perception. Although the psychoacoustic aspects of the CBW have been well studied, the underlying neurophysiology of the CBW has not been as thoroughly examined. The current study examined the neurophysiology of the CBW in young adults, as well as loudness perception in response to the CBW. Auditory stimuli consisting of complex tones of varying bandwidths were presented to 12 individuals (6 male and 6 female, ages 18-26 years). Complex tones were presented around …

The Effects Of Laryngeal Activity On Articulatory Kinematics, Katherine Marie Barber

This thesis examines the efficacy of a social communication intervention in increasing the emotion word productions in school-aged children with language impairment (LI). The study had a multiple baseline single subject design in which 5 children between the ages of 6 and 11 received 20 intervention sessions, each lasting 20 minutes. Intervention activities included reading and discussing children's books, enacting the stories using toys, and journal writing to reflect on experiences in each session. Emotion word productions during intervention sessions were coded for total productions within the categories of happiness, anger, sadness, fear, surprise, and disgust. Productions were also coded …

Automated Grammatical Tagging Of Clinical Language Samples With And Without Salt Coding, Andrea Nielson Hughes

Theses and Dissertations

Language samples are naturalistic sources of information that supersede many of the limitations found in standardized test administration. Although language samples have clinical utility, they are often time intensive. Despite the usefulness of language samples in evaluation and treatment, clinicians may not perform language sample analyses due to the necessary time commitment. Researchers have developed language sample analysis software that automates this process. Coding schemes such as that used by the Systematic Analysis of Language Transcripts (SALT) software were developed to provide more information regarding appropriate grammatical tag selection. The usefulness of SALT precoding in aiding automated grammatical tagging accuracy …

Precoding And The Accuracy Of Automated Analysis Of Child Language Samples, Rachel Christine Winiecke

Theses and Dissertations

Language sample analysis is accepted as the gold standard in child language assessment. Unfortunately it is often viewed as too time consuming for the practicing clinician. Over the last 15 years a great deal of research has been invested in the automated analysis of child language samples to make the process more time efficient. One step in the analysis process may be precoding the sample, as is used in the Systematic Analysis of Language Transcripts (SALT) software. However, a claim has been made (MacWhinney, 2008) that such precoding in fact leads to lower accuracy because of manual coding errors. No …

The Efficacy Of A Social Communication Intervention On Teacher Report Of Withdrawal For Children With Language Impairment, Allyson Roscher

Theses and Dissertations

Recent studies and literature regarding children with language impairment (LI) indicate that these children have difficulty with social communication skills. This study assessed the effect of a social communication intervention on teacher perceptions of withdrawal in six elementary school age participants with LI. The social communication intervention included story sharing, identifying pictures of facial expressions, and journaling to target emotion understanding. The Teacher Behavior Rating Scale (TBRS) was utilized to measure teacher perception of withdrawal. The TBRS examined three subscales of social withdrawal: solitary-active withdrawal, solitary-passive withdrawal, and reticence. Following treatment, teacher ratings of withdrawn behavior decreased for all six …

The Efficacy Of A Social Communication Intervention To Increase Syntactic Complexity In Narratives Of Children With Language Impairment, Alexandra Smith

Theses and Dissertations

Research has shown that children with Language Impairment (LI) struggle with social communication skills in addition to their characteristic syntactic difficulties. This pilot study analyzed the potential change in grammatical complexity in narratives of five children with LI when enrolled in a social communication intervention. The intervention itself focused on teaching emotion understanding by reading and reenacting children’s stories and journaling. Grammatical limitations were indirectly addressed by clinician modeling of complex forms during the intervention sessions. Each child’s productions were assessed and analyzed for grammatical complexity during retelling a book in the Mercer Mayer “a boy, a dog, and a …

Source Localization In Cross Modality Matching Of Brightness And Loudness Of Young Adults, Tawnya Nadine Coates

Theses and Dissertations

Cross modality matching is a magnitude matching procedure, developed to study the relationships between sensory modalities. Auditory and visual sensory integration can be examined through cross modality matching of brightness and loudness. Brightness and loudness are natural correlates of one another as they both represent the parameter of intensity for their respective sensory modalities. Past studies have demonstrated that typical individuals tend to match brighter lights with louder sounds and dimmer lights with softer sounds. The current study utilized a modified cross modality matching procedure, combined with electroencephalography (EEG) data, to examine the cortical response to sensory integration. It was …

Brain Mapping Of The Latency Epochs In A Mcgurk Effect Paradigm In Music Performance And Visual Arts Majors, Lauren Donelle Nordstrom

Theses and Dissertations

The McGurk effect is an illusion that occurs when an auditory /ba/ is combined with a visual /ga/. The two stimuli fuse together which leads to the perception of /da/, a sound in between /ba/ and /ga/. The purpose of this study was to determine whether music performance and visual arts majors process mismatched auditory and visual stimuli, like the McGurk effect, differently. Nine syllable pairs were presented to 10 native English speakers (5 music performance majors and 5 visual arts majors between the ages of 18 and 28 years) in a four-forced-choice response paradigm. Data from event-related potentials were …

External Validity Of Grammatical Word Category Classification Using An Adaptation And Selection Model, Michelle Chatterton

Theses and Dissertations

The process of acquiring language requires children to learn grammatical categories and apply these categories to new words. Researchers have proposed various explanations of this process in the form of algorithms and computational modeling. Recently, adaptation and selection models have been tested and applied as a possible explanation to the process of acquiring grammatical categories. These studies have proven promising, however, the external validity of this approach has not been examined by grammatically coding samples outside the training corpus. The current thesis applies an adaptation and selection model, which pauses the evolution of dictionaries after every thousand cycles to allow …

Modeling Children's Acquisition Of Grammatical Word Categories From Adult Input Using An Adaptation And Selection Algorithm, Nicole Adele Stenquist

Theses and Dissertations

It is understood that children learn the use of grammatical categories in their native language, and previous models have only been partially successful in describing this acquisition. The present study uses an adaptation selection algorithm to continue the work in addressing this question. The input for the computer model is child-directed speech towards three children, ages ranging from 1;1 to 5;1 during the course of sampling. The output of the model consists of the input words labeled with a grammatical category. This output data was evaluated at regular intervals through its ability to correctly identify the grammatical categories of language …

Visual Analog Rating Of Mood By People With Aphasia, Tyson G. Harmon, Katarina L. Haley, Jennifer L. Womack, Sharon W. Williams

Faculty Publications

Background:

Considerable attention has been given to the identification of depression in stroke survivors with aphasia, but there is more limited information about other mood states. Visual analog scales are often used to collect subjective information from people with aphasia. However, the validity of these methods for communicating about mood has not been established in people with moderately to severely impaired language.

Objective:

The dual purposes of this study were to characterize the relative endorsement of negative and positive mood states in people with chronic aphasia after stroke and to examine congruent validity for visual analog rating methods for people …

Language Pathways Defined In A Patient With Left Temporal Lobe Damagesecondary To Traumatic Brain Injury: A Qeeg & Mri Study, Janelle Lee Bailey

Theses and Dissertations

Though the current understanding of language processing is incomplete, it has been established that the left hemisphere is dominant for language in the majority of the population. Damage to language centers of the brain and to white matter tracts connecting these language centers results in a language deficit known as aphasia. Neuroplasticity in the brain can often compensate for these language deficits by strengthening neuronal connections between the right and left hemisphere, or by enhancing the neuronal connectivity of undamaged areas in the left hemisphere. Thus the brain can compensate for damaged language centers by using alternative cortical areas. These …
