Editing Working memory (section)

=== Behavioral genetics ===
Individual differences in working-memory capacity are to some extent [[heritable]]; that is, about half of the variation between individuals is related to differences in their genes.<ref name=":1">{{cite journal | vauthors = Engelhardt LE, Mann FD, Briley DA, Church JA, Harden KP, Tucker-Drob EM | title = Strong genetic overlap between executive functions and intelligence | journal = Journal of Experimental Psychology.
