Executive Function Battery
Executive function tests in the browser. We only picked tests that match paper versions closely in the research. Each test also tracks how the mouse moves. Speed, pauses, wobbles. Research tool, not a diagnosis.

Sampler
In development00 · All constructs · guided demo
One short round of every task, back to back, then a single report that reads across all of them. The fastest way to see the whole battery. Descriptive only, not a diagnosis.
Trail Making (A + B)
In development01 · Processing speed · Set shifting
Connect numbered circles in order as fast as you can. Trial A is just numbers. Trial B switches between numbers and letters.
Digit Span
In development02 · Working memory
Listen to a string of numbers and repeat them back. First forward, then backward. Digital versions land within 0.1 SD of paper.
Verbal Fluency
In development03 · Word retrieval · Lexical access
Say as many words as you can in 60 seconds. One round by starting letter, one by category. Voice is recorded and transcribed. Of every EF test, this one matches paper best.
Color-Word Interference
In development04 · Inhibition · Cognitive control
Name the ink color of color words when word and ink disagree. Four conditions: color alone, word alone, mismatched, and mixed with rule switches.
Tower
In development05 · Planning · Working memory · Inhibition
Move stacked discs from one peg to another without putting a big disc on a small one. Puzzles get harder each round. Scores time to first move, extra moves past the shortest path, rule breaks, and pauses mid-drag.
N-Back
In development06 · Working memory updating
Shapes flash on the screen one at a time. Hit a key when the current one matches the shape from 1, 2, or 3 back. Tracks hits, false alarms, d-prime, and response time at each level.
Why this battery
Current EF tests have real problems. CPT-3 gets the ADHD call right only about 52% of the time. TOVA’s adult norms come from 250 mostly-White college students in 1993. Q-interactive crashes mid-test.
This battery picks up where the research leaves off. Every test we included matches paper versions closely. Then we add what paper can’t catch: how the mouse moves. Speed, hesitation, time to fix a wrong click, total path length.
No diagnostic claims. Phase 0 asks two things. Do the tests hold up in a real practice? And does the mouse-movement data give clinicians anything they can actually use?
