Reflecting on what is “skill” in human motor skill learning

Humans have an exceptional ability to execute a variety of skilled movements. Researchers been long interested in understanding behavioral and neurophysiological basis human motor skill learning for advancing both fundamental neuroscientific knowledge clinical outcomes. However, despite decades work this field there is lack consensus about what meant by “skill” learning. With advent various task paradigms testing behavior increasing heterogeneity assessments methods, it very crucial identify key features order avoid any ambiguity that may result misinterpretation or over-generalization findings, which could serious implications replication translational research. In review, we attempt highlight the following historical approach, considering seminal led first definitions including some contemporary concepts emerging from Overall, based on literature, emphasize has characteristics, such as- (i) optimal movement selection execution, (ii) improved speed accuracy, (iii) reduced variability error. These can emerge as consequence extensive practice/training/learning, thus resulting performance state beyond baseline levels. Finally provide examples model tasks appropriately capture these skill, conclude endeavor aimed at essence should focus aspects.
