03 / LABORATORY EQUIPMENT

Research equipment.

Neurophysiological recording and eye-tracking systems documented in LAPELC²'s institutional inventory. Equipment specifications are distinguished from potential research applications.

01 / ELECTROENCEPHALOGRAPHY256 channels

Geodesic EEG System 400

Electrical Geodesics, Inc. (EGI) · acquired in 2015

LAPELC² has a high-density geodesic EEG system with 256 channels, designed to record electrical brain activity. According to the pMulti/UFAL inventory, its configuration includes sensor nets in three sizes, a high-sensitivity, low-noise amplifier, and a computer equipped with specialized recording and analysis software.

The distribution of electrodes across the scalp makes it possible to examine the timing of neural responses during language tasks. Applications include event-related potentials (ERPs), comparisons of responses to different stimuli, and the investigation of cognitive processes involved in language perception and comprehension. Preparation, recording, and analysis procedures depend on the research protocol.

02 / EYE TRACKING1000 EyeLink

EyeLink 1000

SR Research · acquired in 2012

A camera-based eye tracker that estimates where a participant is looking and how eye position changes during a task. The pMulti/UFAL inventory explicitly identifies the EyeLink 1000 model and describes measurements of fixations (periods during which gaze remains within a region) and saccades (rapid movements between gaze positions).

These measures can be aligned with stimulus presentation and behavioral responses to examine reading, visual scene exploration, attention, and language processing. Interpretation requires defined areas of interest, calibration, signal-quality criteria, and appropriate processing of oculomotor events. The institutional inventory does not specify every accessory or recording mode installed.

03 / EYE TRACKINGII Head Mounted

EyeLink II Head Mounted

SR Research · equipment listed on the FALE institutional website

The EyeLink II is an eye-tracking system mounted on the participant's head. Its design uses eye-facing cameras and head-position tracking, allowing eye movements to be recorded during experiments. It therefore differs from the external-camera configuration typical of the EyeLink 1000.

The system can be used to study fixations, saccades, and the distribution of visual attention in psycholinguistics and cognition experiments. FALE's official website confirms that it is part of the laboratory's inventory, but does not state its acquisition year or complete accessories configuration; those details are therefore not presented as verified.

The systems and records above document the facilities associated with the laboratory. Availability for each protocol, including operational conditions and technical support, must be confirmed before scheduling.

04 / EXPERIMENTAL ENVIRONMENT

Recording spaces.

Sound-treated booth

The laboratory also has a sound-treated booth for experiments requiring controlled acoustic conditions. The suitability of the environment, stimuli, and equipment must be evaluated when planning each study.

Isolation ratings, dimensions, and construction specifications are not reported because they are not available in the institutional records consulted.
