Stroop Memory Test Challenge

Stroop Test Challenge

The Stroop effect is a classic cognitive psychology phenomenon where the time it takes to name the color of a word is longer when the color of the text conflicts with the meaning of the word. For example, the word "RED" printed in blue ink requires more mental effort to identify correctly than a word printed in a matching color.

Test your cognitive control and reaction time. When you see a color word on the screen, ignore what the word says and click the button that matches the COLOR of the text itself. Good luck!

A mini game for Crisis Command, and leadership and decision-making trainer

Leadership & Decision-Making Trainer

Crisis Command

A scenario-based simulator for practicing crisis response, conflict resolution and leadership judgment under time pressure. Every decision trades off between public trust, resources and team morale — exactly like the real thing.

How to play

1. Pick a role and difficulty below, then hit "Begin Simulation."
2. Crises arrive one at a time. Read the situation report and choose one of the response options before the countdown ring closes.
3. Each choice shifts three meters — Public Trust, Resources, Team Morale — shown live on the dashboard. There's rarely a free option: strengthening one often costs another.
4. Letting the timer run out counts as indecision and always costs you — in a real crisis, no decision is still a decision.
5. Survive all rounds with your meters above zero to complete the simulation. Your Leadership Score and decision log are tallied below the game as you play.

Letter Span Memory Test and Game

Cognitive Span Test

Letter Span

What this measures. Letter span is a classic test of short‑term (working) memory. You'll see a string of letters flash one at a time, then have to type them back. Get it right and the string grows by one letter; get it wrong and the session ends, recording the longest string you handled — your span.

Forward vs. backward. Forward span asks for the letters in the order you saw them. Backward span asks for them in reverse order, which leans harder on manipulating information in your head, not just holding it — most people score noticeably lower on it.

Set your options below, then press Begin Session. Your results and history are kept at the bottom of the page.
