Stroop Challenge Go vs Disease Dynamics

Stroop Challenge is a precision cognitive training tool based on the Stroop Effect — one of the most replicated findings in experimental psychology — measuring interference between word reading and color recognition. THE SCIENCE: The Stroop Effect demonstrates that automatic processing (word reading) can interfere with controlled processing (color identification). Regular exposure to Stroop-type stimuli has been associated with improved selective attention, cognitive flexibility, and processing speed. TWO VALIDATED MODES: • Classic (Color-Naming) — Identify the ink color of the presented word. Suppresses automatic reading response. • Word Match (Word-Reading) — Identify the color named by the word. Tests semantic processing independence. METRICS TRACKED: • Score per round (accuracy × speed composite) • Best accuracy rate (percentage of correct responses) • Fastest average reaction time (milliseconds per response) • Session totals: rounds played, correct and incorrect responses • Combo chains: consecutive correct responses DIFFICULTY SCALING: • Easy: 4 color stimuli (Red, Blue, Green, Yellow) • Medium: 5 color stimuli (adds Purple) • Hard: 6 color stimuli (adds Orange) DATA PRIVACY: All data is stored locally via UserDefaults. No network requests are made. No personal information is collected, transmitted, or shared. The app functions completely offline. Ideal for daily cognitive warm-up, focus training, or simply exploring one of psychology's most fascinating phenomena.

Disease Dynamics is a single-player disease strategy game where every outbreak is a tactical race against global containment. Choose a pathogen, select a starting region, evolve transmission routes and symptoms, and react as countries close borders, launch quarantines, and accelerate the cure. The simulation spans 12 world regions with climate, density, healthcare, and wealth affecting spread. Four game modes change the rules: Standard Outbreak, Necroa Outbreak, Neurax Worm, and Simian Uprising.
