Most people practice in "Blocks" (e.g., AAABBBCCC), mastering one thing before moving to the next. This creates a dangerous "Illusion of Competence." Short-Term RAM: When you repeat the same task (e.g., shooting 10 similar math problems), your brain holds the solution in its short-term working memory. You aren't learning; you are just hitting "repeat." This leads to high immediate performance (89%) but terrible retention (20%) because the information never moves to long-term storage. The Reality (The "Reload" Hypothesis): True learning requires Interleaving—mixing different tasks together (e.g., Shoot -> Dribble -> Pass -> Shoot). By switching tasks, you force your brain to "dump" the previous solution and re-construct the motor program or math formula from scratch for the next rep. The Mechanism: Block practice teaches you how to execute a skill. Varied practice teaches you when to use it. By constantly switching problem types, you train the brain to identify the subtle differences between scenarios (Generalization), building a robust "schema" that works even in new, unseen situations.
