What concept explores how the brain retains information when learning is spread out over time?

The concept that explores how the brain retains information when learning is spread out over time is distributed practice. This technique involves spacing out learning sessions, which has been shown to enhance retention and understanding of material. Research indicates that learning is more effective when it occurs over longer periods with intervals between study sessions, rather than cramming information in a short time frame.

The benefits of distributed practice stem from the brain's ability to consolidate information and strengthen neural connections during the intervals of rest. This method allows learners to revisit and reinforce their understanding over time, making it easier to retrieve the knowledge later. In contrast, other methods such as massed practice, which involves intensive study in a short period, tend to lead to quicker forgetting, as the brain may not have adequate time to process and solidify the information.
