A study on the moral implications of human disgust-related emotions detected using EEG-based BCI devices

Abstract

This paper reports results obtained from a set of experiments aiming to compare the behaviour and cerebral rhythms in response to the vision of images related to different types of disgust: core, animal nature and moral. The approach combines Information Technology methods and cognitive technologies (specifically Brain Computer Interfaces) as well as behavioural study methods, especially referring to FACS. The presented experiment has been designed with the intent to define the use of images instead of videos in eliciting a disgust response from participants. A sample of individuals has been involved in a process during which they received visual stimuli based on disgust. The stimuli concerned both core/animal nature disgust and moral disgust. The obtained results show the interesting effects of the reaction of participants, abstracted from freeze framed images, as well as EEG correlates.
