the spacing effect

The spacing effect is a psychological phenomenon where learning and memory improve when study sessions are spaced out over time, rather than crammed into a short period. When you review information at intervals, your brain has more opportunities to reinforce and strengthen the memory, making it easier to recall later. This method leverages the natural way our brains consolidate knowledge, leading to better long-term retention. In essence, spreading out learning sessions helps embed information more deeply compared to studying everything at once.
