Multiple instances of vocal sensorimotor adaptation to frequency-altered feedback within a single experimental...

Vocal sensory-motor adaptation is typically studied by introducing a prolonged change in auditory feedback. While it may be preferable to perform multiple blocks of adaptation within a single experiment, it is possible that a carry-over effect from previous blocks of adaptation may affect the results of subsequent blocks. Speakers were asked to vocalize an /a/ sound and match a target note during ten adaptation blocks. Each block represented a unique combination of target note and shift direction. The adaptation response was found to be similar for all blocks, indicating that there were no carry-over effects from previous blocks of adaptation.
