Cognitive states

Measurement of cognitive states and mental workload

Cognitive states directly influence performance, safety and decision-making. Their measurement makes it possible to analyze mental workload, stress, vigilance and attention in real or simulated situations.

T.E.A. Tech Ergo Appliquées relies on multimodal solutions combining EEG, biofeedback and complementary measurements.

Why measure cognitive states?

• Understand task-related mental workload
• Assess stress and vigilance
• Optimize interfaces and environments
• Study human factors and decision-making processes

What is measured?

EEG

Analysis of brain activity to assess attention, mental fatigue and engagement.

Biofeedback

Measurement of physiological responses related to stress and emotional activation.

Cognitive states

Mental workload, vigilance, attention and engagement.

How is it measured?

Hardware

Wireless T-Sens physiological sensors:

EEG systems (Soma, B-Alert, Thought Technology)

Complementary sensors (physiology, eye-tracking)

Software

CAPTIV ensures synchronization between EEG signals, behavior and task context.

Methodology

Protocols adapted to field studies, with expert interpretation of cognitive data.

Applications
