Facilities

Apal3Our sound attenuated booth is utilized extensively for vocal imitation studies. Outside the booth is a workstation that seats an assistant who controls the experiment. This room also has an extra desk with monitors for running additional perception experiments.  Inside the sound booth, participants hear auditory feedback through comfortable circumaural headphones while clean, high quality vocal recordings are obtained with a dynamic microphone.

EMG recordings also are used for measuring sub-vocalizations in vocal imitation studies. Here a lab member is attaching EMG electrodes to a participant.

The sequence production room is where tapping and keyboard-based experiments are performed. A motion capture camera system is mounted from the ceiling and is used in tapping experiments examining intrinsic timing patterns.

Part of the motion capture system involves attaching apal5tiny light-emitting diodes to each finger (shown here). Light from the diodes are then detected by the motion capture cameras mounted above the participant. As the fingers move upwards and downwards on the tap pad, the camera records the movement of the diodes. After the experiment, recorded velocities and accelerations of each tapping movement undergo detailed analysis.

 

 

 

Computers used at the laboratory workstations are capable of running numerous operating systems and data analysis programs.
