Core Variables
The fundamental cognitive and biological terminology used in our computational research. Understanding these variables is essential for interpreting the Lab v1.1 datasets.
Tactical Tilt Horizon
The mathematically measurable period (in plies) following a significant blunder where a player's centipawn-loss metric remains statistically elevated. We use this to model emotional paralysis and recovery times during competitive play.
View Dataset Metrics →Heuristic Chunking
A cognitive process where individual piece coordinates are bound together into structural templates. This allows masters to bypass the strict 7-item limit of human working memory, enabling instant positional evaluation.
Read Deep Dive →Algorithmic Mimicry
A modern phenomenon where human players unconsciously adopt engine-like positional preferences (e.g., specific pawn pushes or unnatural king safety setups) without possessing the raw calculation depth required to sustain those structures.
Explore the Research →Cognitive Endurance
The biological capacity to maintain calculation accuracy over time. Our research maps how chronobiology (circadian rhythms), sleep cycles, and move-count directly correlate with sharp spikes in endgame error rates.
View Clinical Data →The Fallibility Matrix Framework
These variables form the foundation of our ongoing research into human error. Review our complete methodology to see how we extract these metrics from millions of PGN files.
