Cognitive Load

Cognitive load theory, introduced by Sweller (1988), distinguishes intrinsic load (the inherent complexity of a task), extraneous load (load created by how information is presented, independent of the task itself), and germane load (load devoted to building durable mental models). Performance degrades once total load exceeds working-memory capacity, producing slower responses, missed information, and more errors, regardless of how skilled the performer is in isolation.

Reference: Sweller, 1988. The NeuroRank implementation holds the canonical form and scales interference via task-irrelevant stimulus density.

1. Tracking five separate ability cooldowns while simultaneously executing your own combo in a MOBA teamfight.
2. A cluttered HUD with overlapping kill-feed, minimap, and ability-icon updates raising extraneous load that has nothing to do with the fight itself.
3. The spike in intrinsic load right after a new patch or a new weapon drops, before repetition turns the new information into automatic pattern recognition.

NeuroRank does not report a standalone Cognitive Load score, but the Memory module's escalating grid-recall sequences and the Tracking module's simultaneous cursor-and-prediction demands both stress working-memory capacity directly, and degradation under those conditions is visible in the Working Memory and Tracking Accuracy dimensions.
