Evidence from multiple studies supports the premise that specific structural conditions, such as targeted tasks, immediate feedback, and deliberate guidance, are necessary for practice to effectively improve expert performance.
The retrieved papers consistently emphasize that deliberate practice is not merely repeating an activity, but requires specific structural components like immediate feedback, concentration, expert guidance, and problem-solving opportunities to drive performance gains. Papers 0, 1, 2, 10, and 11 all support the claim, while none refute it, leading to a verdict of SUPPORTED.
