Rooms and equipment
The Socio-Cognitive Laboratory consists of three testing rooms: a video studio, an EEG room, and an eyetracking room. In addition, the lab has a control room, a waiting area and a data processing office. All testing rooms have camera(s) and ceiling-mounted microphones supervised from the control room.
This animation offers a virtual tour of the lab.
Video studio (room 113)
The video studio is equipped with 4 PTZ Full HD cameras, placed in the 4 corners of the room on pegs to adjust the height of the lens. The audio is recorded primarily from the microphones hanging from the ceiling, or additionally from 4 clip-on microphones. All the cameras get the same audio mixed in their video files with minimal drifting between sound and video. The video studio is ideal for conducting, for example, focus-group interviews of participants of all ages, studies of gesture, and collection of conversational data.
EEG room ("pink" room, 115)
The EEG room is equipped with a 128-channel EEG system from BrainProducts. With EEG, we are able to measure electrical activity in the cortex via electrodes on the scalp and investigate online cognitive and sensory processes. EEG is a widely used and safe method that can be applied for various questions spanning from infant language acquisition to language comprehension processes in adults.
Eyetracking room ("green" room, 116)
The lab has two eye-trackers: The Eyelink 1000 Plus has a sampling rate of up to 2000 Hz and allows the precise tracking of eye gaze in infants, children and adults. The SMI RED 250 mobile eyetracker is portable and suitable for testing inside and outside of the lab. With eyetracking, we can measure participants' gaze to objects or events by tracking the position of the pupil and corneal reflections. Because there is a strong link between visual attention and cognitive processes, eyetracking can provide insights into how different types of speakers understand, process and plan speech.
For stimulus presentation, we use Presentation (Neurobehavioral Systems) and E-Prime (Psychology Software Tools), and Analyzer (BrainProducts) for EEG analysis.
Data processing office
On the second floor of Henrik Wergelands hus is a four-desk office especially designed for discreet processing of sensitive data.
