Filter by:The goal of this clinical trial is to examine whether stuttering is associated with a tendency to attend more quickly or for longer durations to threat-related information in the environment (threat-related attention bias). The main questions it aims to answer are: Do adults who stutter, relative to adults who do not stutter, attend to threat-related stimuli more than neutral information? Are attentional biases observed across different types of threat or are they specific to threats related to stuttering experiences? Do measures of attention bias explain individual differences in psychological reactions among adults who stutter?
It will be determined whether bihemispheric stimulation (anodal to the left IFG and cathodal to the right IFG) is used with fluency-facilitating conditions for 5 consecutive days in individuals with stuttering and whether there is a difference in terms of the effects seen in speech fluency compared to the sham condition.
Stuttering negatively impacts communication and reduces the overall quality of life and well-being of individuals who stutter. This study will provide a strong foundation for developing neural and behavioral interventions for stuttering. Participants will be asked to name pictures, read words/sentences silently or aloud, and listen to speech and nonspeech sounds while their speech, muscle, and brain signals are collected. Some participants may also receive brain stimulation while reading and speaking.
The purpose of the study is to use altered auditory vocal feedback to increase fluency in people who stutter and to examine changes in this effect over the course of a one month period occurring outside the laboratory setting.
The purposes of this study are to 1) investigate potential speech, language, and psychosocial contributions to the experience of stuttering in monolingual and multilingual speakers, and to 2) evaluate interdisciplinary, telehealth, and speech-language pathology treatment methods and clinical training specific to fluency disorders.
The purpose of this research study is to understand how speech and language are processed in the brain. This study will provide information that may help with the understanding how speech and language are processed in children and whether there may be differences between children who stutter and children who do not stutter. This project will evaluate these neural processes for speech signals in children who stutter and control subjects through a battery of behavioral speech and language tests, electroencephalography-based (EEG) tasks, functional magnetic resonance imaging (fMRI), and computational modeling.
studying how the cortical auditory evoked potentials differ in children who stutter from who do not stutter and how these potentials change with therapy
The project is leading to investigate the effects of neuromodulation techniques on speech fluency among adults who stutter (AWS). While stuttering is responsive to a variety of treatments in childhood, this is not the case for AWS. Behavioural treatments to reduce stuttering for adults typically consist of speech restructuring methods, which involves the person using one of the altered speech patterns known to increase fluency, such as chorus reading, speaking in rhythm, and prolonging (smoothing/stretching out) speech sounds. Research has shown that behavioural interventions such as these change brain activation patterns in the regions associated with stuttering. Unfortunately, around 70% of AWS who receive these speech restructuring treatments do not maintain the benefits in the longer term and frequently re-present to speech clinics. The aim of this proposed research is to explore whether the brain stimulation using repetitive transcranial magnetic stimulation (rTMS) can consistently enhance effects of behavioural stuttering therapy by examining their responsiveness to the treatment across different outcome measures including a) immediate effect on different speaking contexts, and b) the maintenance of effects over one week after therapy.
Persistent developmental stuttering affects more than three million people in the United States, and it can have profound adverse effects on quality of life. Despite its prevalence and negative impact, stuttering has resisted explanation and effective treatment, due in large part to a poor understanding of the neural processing impairments underlying the disorder. The overall goal of this study is to improve understanding of the brain mechanisms involved in speech motor planning and how these are disrupted in neurogenic speech disorders, like stuttering. The investigators will do this through an integrated combination of experiments that involve speech production, functional MRI, and non-invasive brain stimulation. The study is designed to test hypotheses regarding the brain processes involved in learning and initiating new speech sound sequences and how those processes compare in persons with persistent developmental stuttering and those with typical speech development. These processes will be studied in both adults and children. Additionally, these processes will be investigated in patients with neurodegenerative speech disorders (primary progressive aphasia) to further inform the investigators understanding of the neural mechanisms that support speech motor sequence learning. Together these experiments will result in an improved account of the brain mechanisms underlying speech production in fluent speakers and individuals who stutter, thereby paving the way for the development of new therapies and technologies for addressing this disorder.
In this study, the investigators will research the efficacy of a novel auditory neuro modulating technology that leverages euphonic music tracks with broad-spectrum binaural beats to induce selective EEG spectral power changes.
