    Pennings, H
    2022-05-01 | PDF
    Many professions require procedural skills to perform routine tasks, as well as adaptive skills to deal with unexpected situations. Whereas routine skills are acquired by repetitive practice of the same task, adaptive skills develop with variability of practice. We hypothesize that negative transfer may occur when routine skills are trained with (t ...
