Every test runs in your browser and takes 2 to 15 minutes.
Research paradigms adapted for the browser with millisecond timing precision.
Each test adds a score out of 100 to your results, grouped into 7 domains, so your pattern of strengths and weaknesses takes shape as you go.
A purpose-built interpretation engine compares your results against published normative data and writes a structured report that cites published research.
The test battery is organized around the Cattell-Horn-Carroll (CHC) theory of cognitive abilities, the most widely accepted and empirically supported framework in intelligence research (McGrew, 2009). CHC maps broad cognitive abilities (fluid reasoning, processing speed, working memory) into a hierarchical model validated across cultures and age groups.
The domain structure mirrors the WAIS-V (Wechsler Adult Intelligence Scale, 5th Edition) index structure, supplemented with dyscalculia screening informed by Butterworth's Dyscalculia Screener and Dehaene's Triple Code Model of number processing.
Built with jsPsych, the most widely used library for behavioral experiments online, with timing precision suitable for individual difference measurement.
D-prime, span scores, interference ratios, Weber fractions, response time, and accuracy. Each test reports its own clinically relevant metrics.
This is a screening tool, not a clinical diagnosis. It has not been normed on large populations, and browser-based timing is less precise than laboratory equipment. Results are best used to guide professional referral.
