Research
Developmental stuttering is a multifaceted, complex speech-motor disorder that can have a severe, negative impact on a person’s life. Research in the Speech Fluency laboratory is assessing how emotional reactivity and regulatory processes affect speech-motor control in adults who stutter. Our current project is assessing how social stress influences speech movements in high- and low- socially anxious people who stutter.
INSIDE THE LAB
Speech motor control is assessed using the motion capture technology Optitrack (NaturalPoint, Inc.). This is a motion capture system that allows us to capture lip and jaw movement. The lab is also equipped with Northern Digital’s Wav system (NDI, Inc.). This is an electromagnetic tracking system that enables us to capture tongue movement.
Emotional reactivity and regulation from social stress is measured using Biopac’s MP160 (Biopac, Inc.). This is a data acquisition system that enables us to track heart rate variability and skin conductance levels, indices of emotional processing.
The Speech Fluency Lab has teamed up with Gareth Walkom, founder of withVR. Gareth has created a virtual speaking situation specific to the needs of our current project. The lab is equipped with an HR Omnicept (HP.com) headset for eliciting the virtual reality environment.
