The SLS Labs have 3 double wall sound-proof booths and 2 single wall sound-proof booths, housing the following research facilities:

NeuroScan EEG system
NeuroScan EEG system NeuroScan EEG system

Electroencephalography (EEG) is a non-invasive method to measure electrical activity in the brain. The SLS Lab is equipped with the NeuroScan EEG system with SynAmpsRT amplifiers for both 64 and 128 channels EEG experiments, together with the Curry 7 software to acquire data and STIM2 to present stimuli. Other stimulus presentation software, such as E-prime, and Presentation are also available.

Eyelink 1000 Plus
Eyelink 1000 Plus Eyelink 1000 Plus

The Eyelink 1000 Plus eye tracker allows researchers to track precise eye movements of a participant during a reading task to understand language processing. It has a desktop mount to stabilize the participant’s head during the experiment. It also supports the remote free-to-move mode using stickers. An iMac is paired up with the eye tracker for using the software Experiment Builder and Data Viewer to present stimuli and analyse data.

2 PC workstations
2 PC workstations

Each of the two PC workstations is equipped with a sound interface, a condenser microphone and a pair of headphones for recording speech and performing behavioral experiments.

BioSemi 32 channels EEG system
BioSemi 32 channels EEG system

Similar to the NeuroScan EEG system, the BioSemi EEG system collects brainwaves data. It is a portable EEG system that allows the researcher to conduct EEG experiments with a 32-channel cap.

Tobii Eye-tracker
Tobii Eye-tracker

The Tobii eye tracker is a portable equipment that can capture eye movements of the participant. It is user-friendly and has a simple calibration process. Tobii is located at Room AG316.

Interacoustic AS608 Audiometer
Interacoustic AS608 Audiometer

The Interacoustic AS608 audiometer is used to test the hearing sensitivity of a participant before perception experiments.

Soterix Medical 1x1 tDCS & 4x1 HD-tDCS (transcranial Direct Current Stimulation)
Soterix Medical 1x1 tDCS & 4x1 HD-tDCS (transcranial Direct Current Stimulation)

The Transcranial Direct Current Stimulation (tDCS) system is mainly used for research on speech pathology. The tDCS modulates the brain activity through low levels of constant current. The SLS Lab provides two types of stimulators: 1x1 tDCS and 4x1 HD-tDCS adaptors. The 1x1 tDCS aims to deliver low current to cover a broad area of the brain, whereas the 4x1 HD-tDCS targets a particular and profound region of the brain.

Software

The SLS Lab provides the following software for designing experiments and analyzing data:

  • E-prime (version 2.0 Professional)
  • Presentation
  • BESA
  • MATLAB

 

 


For students and CBS staff who would like to gain access to the SLS Lab for conducting linguistic experiments, please fill in the application form in the following link. Afterwards, you will need to attend a short briefing on how to use the equipment and familiarize yourself with the lab rules.
