Why Interleaving Works
Interleaving involves studying different but related topics in a single session, rather than blocking all time on one topic. This forces your brain to constantly switch gears, which improves your ability to discriminate between concepts and strengthens retrieval. It's like practicing different types of problems in math rather than doing all addition problems first.
Example: Learning Psychology
Instead of studying all of memory theories in one block, you mix in a bit of perception and learning. When you switch between topics, you have to retrieve the relevant context each time, which makes the memory stronger and helps you see the connections between different theories.
