Dynamic Difficulty Adjustment in a P300 Speller Task for Attention Training

NCT05576649 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 51

Summary

This study compares different adaptation approaches in a P300-based BCI neurofeedback training to improve short-term attention. Participants will spell several words on a computer by focusing on a letter on the screen while their brain activity is recorded (P300 speller). The difficulty of this task will be adapted to train their attention. Their cognitive abilities will be evaluated using a random dot kinematogram, where they are asked to indicate the direction a fraction of moving dots on the computer screen is going in, before and after the training to analyse any improvements. Questionnaires will be used to compare the perceived task load of the different adaptation approaches.
