Cognitive Flexibility

Cognitive flexibility is the ability to shift perspective, strategy, or response rules when a situation demands it, rather than persisting with a plan that has stopped fitting the moment. Diamond's (2013) influential review of executive function places cognitive flexibility as the third of three core executive functions, built on top of the other two: it requires holding a rule in working memory and inhibiting the pull of the previous rule before the new one can be applied cleanly. Flexibility deficits show up as perseveration, continuing an old strategy past the point it stopped working, a pattern that is easy to spot in competitive play when a player keeps running a read the opponent has clearly adjusted to.

Reference: Diamond, 2013. The NeuroRank implementation holds the canonical form and scales interference via task-irrelevant stimulus density.

1. Abandoning a planned aggressive entry the instant new information (a sound cue, a rotation) makes the read stale, without needing to consciously talk yourself out of the old plan.
2. A support player switching from a peel-focused mindset to an engage-focused one mid-fight when the win condition flips.
3. Adjusting a loadout or itemization strategy mid-match after identifying a counter, rather than forcing the pre-match plan through.

NeuroRank does not currently run a dedicated set-shifting or rule-switching paradigm, so cognitive flexibility itself is not scored as a standalone dimension. The closest available signal is Decision Quality, drawn from choice-RT accuracy and go/no-go commission errors in the Reaction module, which reflects the ability to select correctly among competing response options, a prerequisite for flexible responding even though it does not directly test switching between rules.
