Evidence	Context
Roughly 3–5 chunks	Na summary from different experiments under particular conditions, no be new measurement of worldwide average. Original abstract
Units matter	Familiar groups fit work as chunks, so number of items no dey show pure storage capacity by itself. Review
No matching Helibrain cutoff	Visual pattern game no dey repeat all the review's experimental controls.

Wetin dey affect am?

Rehearsal, wetin person sabi before and grouping fit help person remember. The review's estimate of restricted capacity purposely separate those kinds of help from the central limit wey e dey describe. Review

The review na about temporary storage under controlled conditions. E no set limit for everything wey you fit learn.

Number memory na the same kind of measurement?

The way dem present and score them no be the same. Make person no compare digit span and visual pattern level as if dem be the same units.
