Registro de neuroseñales con una Interfaz Cerebro-Computador para estimar el nivel estrés en un estudiante durante una clase

Abstract

Introduction: This work shows an individual study of the capture, recording, and analysis of the level of stress of a university student during a class that involves an evaluation. The stress information was estimated using a commercial and low-cost computer-brain interface. This allows solving the problem of easily obtaining quantitative and not only qualitative measures.

Objective: The aim of this article is to analyze the behavior of neural signals to estimate the level of stress in a student to some verbal and nonverbal events generated by a teacher.

Methodology: An experimental design of individual character was developed taking as disturbances the level of stress, events such as questions, time limits, and gestures.

Results: Some events that caused stress in students produced by the verbal and non-verbal language of the teacher when teaching the class were evidenced.

Conclusions: Teachers are encouraged to moderate their body language during assessments by avoiding actions that emulate anxieties or pressures in unnecessary times.
