The TL;DR of the article provides two links to the preprint, and in fact there is a Springer version accessible without cost: https://link.springer.com/content/pdf/10.3758/s13423-017-1317-5.pdf https://link.springer.com/content/pdf/10.3758/s13423-017-131... Even less friction than Sci-Hub is the Unpaywall browser extension http://unpaywall.org/products/extension http://unpaywall.org/products/extension which finds links to unpaywalled content matching paywalled journal articles.
