Eeg-Based Processing And Classification Methodologies For Autism Spectrum Disorder: A Review, Gunavaran Brihadiswaran, Dilantha Haputhanthri, Sahan Gunathilaka, Dulani Meedeniya, Sampath Jayarathna

Computer Science Faculty Publications

Autism Spectrum Disorder is a lifelong neurodevelopmental condition which affects social interaction, communication and behaviour of an individual. The symptoms are diverse with different levels of severity. Recent studies have revealed that early intervention is highly effective for improving the condition. However, current ASD diagnostic criteria are subjective which makes early diagnosis challenging, due to the unavailability of well-defined medical tests to diagnose ASD. Over the years, several objective measures utilizing abnormalities found in EEG signals and statistical analysis have been proposed. Machine learning based approaches provide more flexibility and have produced better results in ASD classification. This paper presents …

Electroencephalogram (Eeg) For Delineating Objective Measure Of Autism Spectrum Disorder, Sampath Jayarathna, Yasith Jayawardana, Mark Jaime, Sashi Thapaliya

Computer Science Faculty Publications

Autism spectrum disorder (ASD) is a developmental disorder that often impairs a child's normal development of the brain. According to CDC, it is estimated that 1 in 6 children in the US suffer from development disorders, and 1 in 68 children in the US suffer from ASD. This condition has a negative impact on a person's ability to hear, socialize, and communicate. Subjective measures often take more time, resources, and have false positives or false negatives. There is a need for efficient objective measures that can help in diagnosing this disease early as possible with less effort. EEG measures the …

An Intensive Book Camp Approach To The Remediation Of Speech Sound Disorders: A Case Report, Shawn L. Nissen, Melanie E. Peris, Kristine Tanner

Faculty Publications

Background: Understanding treatment dose is essential to optimizing therapeutic frequency and intensity for speech sound disorders. Intensive therapies, known as boot camp approaches, have proven efficacious in certain speech therapy contexts such as voice disorder treatment. However, few data exist regarding intervention intensity for developmental speech sound disorders. Method: This investigation examined the effects of an intensive boot camp speech therapy approach to remediate interdental /s/ production over two consecutive days. Treatment occurred in morning and afternoon blocks for a total of 5.5 h per day. Auditory-perceptual ratings were used to evaluate /s/ productions pre-treatment, immediately post-treatment, and one week …

Redmond (2002) Revisited: Have Standardized Behavioral Rating Scales Gotten Better At Accommodating For Overlapping Symptoms With Language Impairment?, Kirsten M. Hannig, Sean M. Redmond, Amy Wilder

Faculty Publications

Seventeen years ago, Redmond ¹ reviewed five standardized behavioral rating scales and identified several aspects of their design that made them prone to mischaracterize language impairments as socioemotional behavioral disorders. The purpose of this report is to provide an update and extension of the original audit. We consulted test manuals to evaluate: (1) representation of children with language impairments in their standardization samples; (2) presence of language, or academic items within their inventories; (3) accommodations for administering the measure to children with language impairments; and (4) procedures for identifying inordinately punitive ratings. Overlapping language and academic symptoms continued to be …

Automated Speech Recognition In Adult Stroke Survivors: Comparing Human And Computer Transcriptions, Tyson G. Harmon, Adam Jacks, Katarina L. Haley, Gary Bishop

Faculty Publications

Objective: Speech sound errors are common in people with a variety of communication disorders and can result in impaired message transmission to listeners. Valid and reliable metrics exist to quantify this problem, but they are rarely used in clinical settings due to the time-intensive nature of speech transcription by humans. Automated speech recognition (ASR) technologies have advanced substantially in recent years, enabling them to serve as realistic proxies for human listeners. This study aimed to determine how closely transcription scores from human listeners correspond to scores from an ASR system. Patients and Methods: Sentence recordings from 10 stroke survivors with …

Bidirectional Interference Between Simulated Driving And Speaking, Christopher Dromey, Kelsey Simmons

Faculty Publications

Purpose: This study relied on acoustic measures of connected speech and several indices of driving performance to quantify interference between speaking and simulated driving. Method: Three groups of 20 younger (ages 20–30 years), middle-age (ages 40–50 years), and older (ages 60–71 years) adults produced monologues and completed a simulated driving task, which involved maintaining a constant speed and lane position on a freeway. Both tasks were completed separately and concurrently. Results: There were significant divided attention effects, with a reduced speaking time ratio, and increases in vocal intensity, speed variability, and steering wheel adjustments. There was a significant between-subjects age …

Somatosensory Cross-Modal Reorganization In Children With Cochlear Implants, Garrett Cardon, Anu Sharma

Faculty Publications

Deprived of sensory input, as in deafness, the brain tends to reorganize. Cross-modal reorganization occurs when cortices associated with deficient sensory modalities are recruited by other, intact senses for processing of the latter’s sensory input. Studies have shown that this type of reorganization may affect outcomes when sensory stimulation is later introduced via intervention devices. One such device is the cochlear implant (CI). Hundreds of thousands of CIs have been fitted on people with hearing impairment worldwide, many of them children. Factors such as age of implantation have proven useful in predicting speech perception outcome with these devices in children. …

Outcomes Of An Intensive Exercise-Based Swallowing Program For Persons With Parkinson's Disease: A Single-Case Experiment, Jocelyn Jenks

Dissertations and Theses @ UNI

The leading cause of death in Parkinson’s disease (PD) is aspiration pneumonia, a negative consequence of swallowing impairment. Approximately 80%, and upward of 95%, of persons with Parkinson’s disease (PwPD) will present with progressive dysphagia, or swallowing impairment. Dysphagia may also lead to dehydration, malnutrition, weight loss, reduced quality of life, hospital readmissions, and high financial burden. Recent evidence suggests swallowing exercise is beneficial for PwPD and there is growing evidence that supports intense programs combining exercises, which may provide sufficient treatment intensity to improve swallowing. The present study investigated whether a four-week Intensive exercise-based Swallowing Program (ISP) combining lingual …

Cortical Stimulation Mapping Of Heschl’S Gyrus In The Auditory Cortex For Tinnitus Treatment, Austin Huang

CMC Senior Theses

Tinnitus is the perception of sound in the absence of an actual sound stimulus. Recent developments have shifted the focus to the central nervous system and the neural correlate of tinnitus. Broadly, tinnitus involves cortical map rearrangement, pathological neural synchrony, and increased spontaneous firing rates. Various cortical regions, such as Heschl’s gyrus in the auditory cortex, have been found to be associated with different aspects of tinnitus, such as perception and loudness. I propose a cortical stimulation mapping study of Heschl’s gyrus using a depth and subdural electrode montage to conduct electrocorticography. This study would provide high-resolution data on abnormal …

Speech Fluency In Acquired Apraxia Of Speech During Narrative Discourse: Group Comparisons And Dual Task Effects, Tyson G. Harmon, Adam Jacks, Katarina L. Haley

Faculty Publications

Purpose: Slowed speech and interruptions to the flow of connected speech are common in aphasia. These features are also observed during dual task performance for neurotypical adults. The purposes of this study were to determine (a) whether indices of fluency related to cognitive-linguistic versus motor processing would differ between speakers with aphasia plus AOS and speakers with aphasia only and (b) whether cognitive load reduces fluency in speakers with aphasia with and without AOS.

Method: Fourteen speakers with aphasia (seven with AOS) and seven neurotypical controls retold short stories alone (single task) and while simultaneously distinguishing between a high and …

Pupillometry As A Test Of Infant Word Recognition, Amy Vinyard

Masters Theses, 2010-2019

Pupillometry holds great promise as a tool for infant language research but has not yet been used to probe word recognition. The goal of the described study was to design a functioning method that can later be used to test the possibility of using pupil dilation as a gauge of word recognition in 11-month-olds. To do this, we used the methods of an existing study (The Role of Accentual Pattern in Early Lexical Representation, Vihman, Nakai, DePaolis, & Hallé 2004) with modifications. Our method ran a one-sided head turn preference paradigm with the addition of an eye tracker for pupil …

Mainstream Tablets As Speech Generating Devices: Considerations In Decision Making, Kaylee Sienza, Ann R. Beck, Amy L. Yacucci

Graduate Independent Studies - Communication Sciences and Disorders

In the last several years, the field of augmentative and alternative communication (AAC) has seen significant technological advances that are both innovative and exciting. One of the main advances in technology comes in AAC applications on mainstream tablet devices like iPads. Tablet devices with AAC applications are being explored as an alternative to dedicated speech generating devices due to cost and convenience. But, before choosing between a mainstream tablet AAC device and a dedicated AAC device, there are several foundational elements of AAC to be understood. All of the AAC basics and considerations should be part of the assessment process …

Augmentative And Alternative Communication In The Intensive Care Unit: A Service Delivery Model, Beverly Lloyd, Ann R. Beck, Amy L. Yacucci

Graduate Independent Studies - Communication Sciences and Disorders

Patients in the intensive care unit (ICU) often find it difficult or impossible to verbally communicate due to mechanical ventilation, tracheostomy tubes or increased fatigue and delirium. Augmentative and alternative communication (AAC) can provide ICU patients with a way to communicate during their ICU admittance. However, few hospitals currently have a systematic service delivery model in place for providing AAC tools and supports to ICU patients. This resource manual provides an outline for creating and implementing an AAC service delivery model along with AAC materials and resources appropriate for an ICU. Explanations of how each material is used, who they …

Examining The Learning Of Students Participating In An Interactive Simulated Patient Experience, Mary Smyers

Theses and Dissertations

Simulated patients are becoming increasingly used in the educational program of future speech-language pathologists. The use of standardized patients provides the opportunity to teach students clinical skills in a controlled environment (Bradley, 2006; Zraick, 2012). Simucase, a speech-language pathology software program, allows clinicians to practice their assessment and treatment skills on virtual patients and is a valid method when teaching clinical skills. Thus, this project examined five undergraduate senior clinicians’ performance and reflection about the Simucase program and their own clinical knowledge. The undergraduate student clinicians engaged in controlled simulation experiences that shared similar characteristics to their current clients, and …

P300 Event-Related Potentials To A Phoneme Discrimination Task Requiring A Motor Response, Kaitlyn Chelsea Turner

Theses and Dissertations

Speech perception typically takes place within the auditory cortex as evidenced by data collected using quantitative electroencephalography (qEEG). The purpose of this study was to determine if motor responses influence speech perception. We examined P300 event-related potentials during oddball stimulus recognition tasks that either required or did not require a motor response. Based on a review of the literature, it was hypothesized that similar areas of the brain would be activated in both the motor response task and the same task without a motor response immediately following the button-push condition. Two syllables, /ba/ and /ga/, were presented to 20 native …
