WEB-BASED NEUROPSYCHOLOGICAL EXECUTIVE-ASSESSMENT BATTERY: A COMPUTERIZED ADAPTATION OF TRADITIONAL PAPER-AND-PENCIL TESTS

This study presents a comprehensive web-based neuropsychological assessment battery comprising six computerized adaptations of established executive function tests: the Trail Making Test (A and B), Tower of London, Corsi Block-Tapping Test (forward and backward), Wisconsin Card Sorting Test, a 24-item Stroop task, and verbal fluency tasks (phonological and semantic). Developed entirely in JavaScript using HTML5 Canvas API and modern web standards, the battery is currently undergoing validation with 150 participants aged 20-30 years.Two principal advantages distinguish this platform from traditional paper-and-pencil assessments. First, the fully online implementation enables universal accessibility without specialized equipment or training, facilitating standardized administration across diverse settings through any standard web browser. This eliminates examiner variability and enables remote assessment while maintaining psychometric rigor.
Second, the system captures fine-grained inter-item reaction times alongside conventional performance metrics (accuracy, completion time, error rates). This temporal granularity provides unprecedented opportunities for fundamental research into executive function subprocesses, including the dynamics of planning, cognitive flexibility, working memory updating, and inhibitory control mechanisms. Traditional paper-and-pencil versions cannot capture these millisecond-level temporal patterns that reveal underlying cognitive processing strategies.
The platform implements automated data collection with CSV export, built-in quality control features, and standardized protocols. All source code will be made available on GitHub to facilitate replication by the community. This accessible, standardized battery addresses the demand for remote neuropsychological evaluation while opening new methodological possibilities for cognitive neuroscience research through detailed temporal analysis of executive control processes. Normalization results from the ongoing validation study will be presented in the poster.
