Adolescence is a developmental period of significant risk for anxiety, depressive symptoms, and suicidality, and the investigators propose to target key peer-based risk and protective factors using Cooperative Learning (CL). CL is a small-group instructional approach that can enhance peer relations and reduce peer-related risks, as well as promote academic engagement and achievement and reduce racial disparities. CL will be delivered with the aid of technology that automates the design and delivery of CL lessons, promoting rapid implementation, scalability, high fidelity, accessibility, and sustainability.

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. Read Less

The purpose of this study is to test if priming expectations of transcranial Direct Current Stimulation (tDCS) can improve the efficacy of tDCS in enhancing motor learning. Read Less

The investigators propose to investigate Microbiota Transfer Therapy (MTT) for treating patients with Pitt-Hopkins Syndrome (PTHS) and gastrointestinal problems (constipation, bloating, abdominal pain). MTT involves a combination of 10 days of oral vancomycin (an antibiotic to kill pathogenic bacteria), followed by 1 day of bowel cleanse using magnesium citrate, followed by 4 days of high dose MTP-101P with an antacid, followed by 12 weeks of a lower maintenance dose of MTP-101P with an antacid.

Patients with hearing loss who use cochlear implants (CIs) show significant deficits and strong unexplained intersubject variability in their perception and production of spoken emotions in speech. This project will investigate the hypothesis that "cue-weighting", or how patients utilize the different acoustic cues to emotion, accounts for significant variance in emotional communication with CIs. The results will focus on children with CIs, but parallel measures in postlingually deaf adults with CIs will be made, ensuring that results of these studies benefit social communication by CI patients across the lifespan by informing the development of technological innovations and improved clinical protocols.

The goal of this clinical trial is to test the effectiveness of START (Startle Adjuvant Rehabilitation Therapy) in improving arm function after a stroke. The main questions it aims to answer are 1) Does startle rehabilitation therapy improve functional arm performance after training on a specific task and 2) Can training benefits, if any, be seen in other untrained tasks? Researchers will enroll participants across a wide range of upper extremity impairments post-stroke. Participants will be enrolled in three consecutive days of in-person training on an upper extremity task followed by a single-day follow-up session one month after training is completed. Each training session will last for approximately 3 hours per day. Participants will be randomly assigned to one of two groups; 1) Arm training with START and 2) Arm training without START. Study participants and assessors will be blinded to the type of training received. Before the training, participants will be clinically assessed to determine impairment level. During training, participants will be asked to perform; 1) a simulated feed task which involves transferring kidney beans using a spoon from one cup (start position) to another cup (end position) in front of them OR 2) A functional reaching task where participants will maintain a tool (spoon) in their hand while extending their arm forward towards an end position based on the severity of arm impairment as determined by the clinical assessment. Researchers will compare the % change in trained task scores, muscle activity, and arm movement outcome measures at three-time points; baseline on day 1, at the end of training on day 3, and one month after training.
