Investigating the multicausality of processing speed deficits across developmental disorders with eye tracking and EEG: extended abstract

Abstract

Neuropsychological tests inform about performance differences in cognitive functions but they typically tell little about the causes for these differences. Here, we propose a project which builds upon a recently developed novel multimodal neuroscientific approach of simultanous eye-tracking and EEG measurements to provide insights into diverse causes of performance differences in the Symbol Search Test (SST). Using a unique large dataset we plan to investigate the causes for performance differences in the SST in healthy and clinically diagnosed children and adolescents. Firstly, we aim to investigate how causes for differences in performance in the SST evolve over age in healthy, typically developing children. With this we plan to dissect aging effects from effects that are specific to developmental neuropsychiatric disorders. Secondly, we will include subjects with deficient performance to investigate different causes for bad performance to identify data-driven subgroups of poor performers.
