The present invention relates to the field of neurological assessments and, in particular, to the assessment of Information Processing Speed in the context of drug research and development, diagnostics and patient and health care management. More specifically, it pertains to a computer-implemented method for automatically assessing information processing speed in a test subject comprising the steps of determining at least one first qualimetric activity parameter for sensorial transmission, cognition and motoric output activity and at least one second qualimetric activity parameter for sensorial transmission and motoric output activity in a preexisting dataset of cognitive oculomotor activity measurements obtained from said test subject, determining at least one third qualimetric activity parameter for cognition by comparing the said first and the said second qualimetric activity parameter to each other, and assessing the information processing speed in a subject based on the at least one first, second and third qualimetric activity parameter. The present invention further contemplates a method for determining cognitive impairment in a subject suspected to suffer therefrom comprising determining information processing speed, and determining the cognitive impairment based on the determined information processing speed. The invention also provides for a mobile device or system for carrying out the methods of the invention as well as the use of said mobile device or system for assessing information processing speed and/or cognitive impairment.La présente invention concerne le domaine des évaluations neurologiques et, en particulier, l'évaluation de la vitesse de traitement d'informations dans le contexte de la recherche et de la mise au point de médicaments, du diagnostic et de la gestion du patient et des soins de santé. Plus particulièrement, l'invention concerne un procédé mis en œuvre par ordinateur pour évaluer automatiquement une vitesse de traitement d'informat
