Facilities provided by the department: overview
EyeLink eye-tracking system
The EyeLink 1000 system is an advanced eye-tracking system, based on the non-invasive acquisition of eye movements using video technology. Its capability includes:
- Extremely high spatial resolution measurements of an average of 0.15° accuracy.
- Fast video sampling rates of 1000 Hz.
- Network link (Ethernet) connects eye-tracking computer to experiment's subject-display computer. Support for real-time data transfer and protocol.
- On-line analysis of eye movement data into saccades, fixations and blinks. Data is automatically stored into a data file for flexible post-acquisition and analysis.

ERP System
The Laboratory of Experimental Psychology has an EEG-lab which enables ERP
(Event-Related Potentials) research. The ERP is an electrical change recorded
from the brain in relation to an event that occurs either in the external
world or within the brain itself. By looking at ERP components we are able
to study online cognitive processes with a high temporal resolution.
The lab is equipped with a regular EEG-cap and an EEG-cap with active electrodes.
Both these caps can measure up to 64 EEG channels and have a standard 10-20 electrode placement.
The software packages for data acquisition (cognitrace) and data analysis
(Eeprobe) were provided by ANT (from ANT, Enschede, The Netherlands).
