Description¶

How long a learner can sustain focus, and how readily something else takes it. Distinct from working memory: attention governs what reaches the store, capacity governs what it holds. It converts into segment length, distractor design, and how much a page may hold in one uninterrupted run. The design lever is mostly subtractive — the strongest findings here are about what to remove [-M].

Implications¶

Context¶

Sets segment length and how much a page may present in one uninterrupted run.
Interesting-but-irrelevant material is the classic trap: it raises reported engagement and lowers learning [-M].
Signalling is the additive counterpart — directing attention rather than competing for it [+M].

Target Learners¶

Younger learners and anyone with attention-related differences, for whom segment length is not a stylistic choice.
Learners in environments they do not control — noise, interruption, shared devices.

Target Learning Objectives¶

Affects anything requiring sustained processing: extended reading, multi-step problems, video.
Largely irrelevant to short retrieval tasks, which is why brief checks survive conditions long tasks do not.

The evidence by question¶

Does making material more interesting with details that do not carry the target cost learning? Interesting but irrelevant details can impair comprehension and transfer, with effects that vary with the material and the learner [+S]
Does breaking a continuous presentation into segments improve learning over presenting it whole? Segmenting Improves Multimedia Learning [+M]
Does physical activity during the school day (movement breaks, active lessons, organised active recess) improve children's on-task behavior and readiness for class? Classroom physical activity increases children's on-task behaviour, with no consistent gain on attention or other cognitive tests [~S]
Can a mindfulness or cognitive-training programme improve learners' attention itself? Across all RCTs, mindfulness-based interventions significantly improve mindfulness, executive functioning, attention, depression, anxiety/stress and negative behaviours in youth, with small effect sizes [+M]

Working memory — the adjacent bottleneck, and the one this is most often confused with.
Affect regulation — anxiety consumes attention directly, so the two compound.
Time and continuity — whether a task can finish before attention has to be re-established.

Examples¶

Attention — the element that names the design target
Proximity — places related material where attention does not have to travel
Signaling — cues the structure so attention lands on what carries the point
Brain Breaks — short resets between sustained runs
Movement Breaks — the physical-activity remedy in practice
