What the study is about

This study meets the NIH definition of a clinical trial, but is not a treatment study. Instead, the goal of this study is to investigate how hearing ourselves speak affects the planning and execution of speech movements. The study investigates this topic in both typical speakers and in patients with Deep Brain Stimulation (DBS) implants. The main questions it aims to answer are:

  • Does the way we hear our own speech while talking affect future speech movements?
  • Can the speech of DBS patients reveal which brain areas are involved in adjusting speech movements? Participants will read words, sentences, or series of random syllables from a computer monitor while their speech is being recorded. For some participants, an electrode cap is also used to record brain activity during these tasks. And for DBS patients, the tasks will be performed with the stimulator ON and with the stimulator OFF.

Being studied: Auditory feedback perturbation during speech; Visual feedback perturbation during reaching; DBS stimulation ON/OFF

Conditions: Speech

  • 250-4000 Hz pure tone hearing thresholds equal to or better than 25 dB HL for children and young adults and equal to or better than 35 dB HL for older adults
  • no medications that affect sensorimotor functioning (except for in the DBS group)
  • adult subjects: 18 years of age or older
  • typical children: 4;0 to 6;11 [years;months] or 10;0 to 12;11 [years;months])

Specific inclusion criteria for children

Specific inclusion criteria for DBS patients:
