Study 11: Vocal Characteristics Study

Enabled:Statistics Tracking
Study Title: Vocal Characteristics Study
IRB Approval Number: IRB-2019-145
Experimenter(s): Jack Purcell (student), Joshua Tatz, Zehra Peynircioglu
Contact Info:
Time Commitment: 1 to 2 hours (1 hour in lab + other time finding materials) 2 credits
Eligibility Requirements: Having recordings of childhood voice (age 3 to 12) available. The voice samples should involve a minimum of 3 sentences with at least 3 words each. No known, existing speech diagnoses.
Description: This study has two phases: 1) Please send an online link to the voice recordings OR arrange to give us the recordings on any digitized medium (e.g., camcorder, CD) or cassette tape. Please note that all of recordings will be made anonymous and no personal information will be used. We will not be using any visual materials that may accompany the recordings. 2) The experimenter will then arrange a meeting time with you to record your speaking voice.

Study 2: Cerebro-cerebellar circuits in autism spectrum disorder

Enabled:Statistics Tracking
Study title: Cerebro-cerebellar circuits in autism spectrum disorder 
IRB Approval number: IRB-2016-188  
Experimenter’s name: Laura Blevins
Contact info:
Time Commitment: 3 hours
Number of credits (1 credit = approx. 1 hour commitment): 3 credits
Eligibility requirements: Males with Autism, Age 18-40, Right-handed, Native English Speaker
Description of study: Participants attend three study sessions scheduled one week apart at the Center for Functional and Molecular Imaging at Georgetown University. During each session, participants perform a series of motor and cognitive tasks after transcranial direct current stimulation (tDCS) is applied over the cerebellum. tDCS is a non‐invasive technique that delivers a very small electrical current (like a 9 Volt battery) to the scalp. Participants will take part in a brain imaging study following tDCS. Each session will take about 1‐ 2 hours, and participants can be compensated with Psychology research participation credit OR $50 per session.

Study 5: Effects of cerebellar tDCS on reading

Study title: Effects of cerebellar tDCS on reading
IRB Approval number: IRB-2018-271
Experimenter’s name:* Marissa Marko, Dr. Catherine Stoodley
Contact info:;
Time Commitment: up to 3 hours (1 hour per session)
Number of credits (1 credit = approx. 1 hour commitment): 1-3 credits
Eligibility requirements: Adults with and without dyslexia are invited to participate as long as they meet the following criteria: ability to provide consent, right-handed, native English-speaker, between ages 18-40, no diagnosis of a neurological, psychiatric, or developmental disorder (other than dyslexia), no history of serious head trauma, not currently pregnant (if applicable), no metal implants, no cochlear implants, no pacemakers, not currently taking medications (i.e. anti-psychotics, anti-depressants, anti-convulsants, sedative/hypnotics). 
Description of study:  The current study seeks to investigate the relationship between the cerebellum and reading in people with and without developmental dyslexia. We will utilize transcranial direct current stimulation (tDCS), a non-invasive neuromodulatory method, which directs a small amount of electrical current (2 mA) onto the cerebellum for 20 minutes. After 20 minutes of tDCS, participants will complete a set of reading-related tasks. Participants will complete 3 tDCS testing sessions over the course of 3 weeks (each session 1 week apart).
