I was really missing this from the article. I&#x27;d describe it as &quot;play&quot; to get to know the system you are trying to learn. This knowledge than helps with the specific task.<p>Given the study I assume a different mechanism coming in to play also:<p>If you try to play a musical piece on an instrument teachers will advise you to practice as slow as needed, not to make a single mistake, that could end up being learned.<p>It&#x27;s like trying to correct yourself on word you mangled up while speaking, you&#x27;ll be so fixated you immediately make the mistake again and again.<p>This memory effect might have been countered by the variations in the study.
