Performance plateaus often require a change in approach to surmount

Purposeful practice, after Ericsson and Pool requires that you’re always pushing your comfort zone. By honing a given set of practices, it’s often possible to perform incrementally better, but returns usually diminish. At that point, “generally the solution is not ‘try harder’ but rather ‘try differently’” (Ericsson & Pool, 2016, p. 19). (Compare to Naive approaches to practice rapidly plateau)

Consequently: Practice efficacy is highly sensitive to method design.

Coaches can help here, since they’re generally familiar with the barriers you might encounter, and what alternative approaches might help.

Nicely summarized by “What got you here won’t get you there.” (Marshall Goldsmith).

Empirical examples:

  • In a series of experiments on Span of working memory, Chase and Ericsson report that their subject was stuck at a plateau until he replaced his initial strategy of rehearsal with a mnemonic technique (1981, p. 146–147).
