Attention Span

Attention span refers to the maximum duration over which an individual can maintain focused, productive attention on a single task without involuntary mind-wandering or measurable performance decline. It is closely related to sustained attention but emphasises a time-limit framing: not whether you can sustain attention, but for how long before drift becomes significant. Research shows that attention span is not fixed and varies substantially with task difficulty, motivational salience, individual differences in working memory capacity, and arousal state. The widely circulated claim that human attention span has shortened to eight seconds is not supported by peer-reviewed evidence and conflates different attentional constructs.

Reference: James, 1890; Smallwood & Schooler, 2015. The NeuroRank implementation holds the canonical form and scales interference via task-irrelevant stimulus density.

1. Maintaining active map awareness for the full duration of a League of Legends game rather than lapsing into tunnel-vision on local skirmishes as match length increases.
2. Watching a corner in CS2 across an entire round of static play without attention drifting to a teammate voice line or a background notification on screen.
3. Sustaining consistent awareness of all active threat vectors across a long Apex Legends match, where action density is low in the early game and spikes sharply at end-ring.

Attention span is not a standalone NeuroRank dimension but is partially indexed by consistency scores, which capture how performance holds across the full trial sequence of a module. Players whose accuracy and RT degrade toward the end of a module demonstrate attention decay, a pattern visible in the trial-by-trial records of the Composure and Reaction modules.
