Estimating elementary cognitive functions based on EEG signals analysis

Human performance in complex mental tasks relies on elementary cognitive abilities, e.g., information processing speed and working memory capacity. These elementary functions can be measured on a behavioral level using elementary tasks, e.g., reaction time and memory scanning tasks. Cognitive and behavioral neuroscience aims to reveal cortical activity features underlying human performance in the elementary cognitive tasks. In this work, we designed a reaction time task based on the processing of ambiguous sensory stimuli. We found a correlation between the task performance on the behavioral level and the sensor-level cortical activity.
