Deliberate practice in 1970s: Digit-span training

The log for Deliberate practice in 1970s is the line “Digit-span training.” The figure written with it is 10. Do not convert that figure into a group intelligence score or an inborn grade.

Skill carry-over across domains; usually limited. Figures valid only inside a dated window. Country/language notes that must not stay English under a local URL. Prefer dated bands over current live figures. Labs and universities publish methods — not destiny scores for groups. Selection systems here are individual pathways without race or nation ranks.
