This is all speculation, on my part (certainly not an expert in this area)<p>In the article they say that &quot;Contextual variability can strengthen retention [15] and generalization of skills&quot;, but that they &quot;chose to increase sensorimotor variability while maintaining constant the original learning context.&quot;<p>They also mention that &quot;attributing errors to internal sources can strengthen learning [19, 20] and generalization [21] of motor behavior&quot;<p>My guess for an autodidact would be how powerful internal attribution is compared to the change in context and exploration of the sensorimotor space. Of course, they&#x27;re probably not discrete, and probably also impact one another.<p>Sounds like some really interesting possible implications, and possibilities for further research. Really makes me want to reread the article and go through some of the articles they cite
