In memory studies, what effect does spacing out study sessions have?

Spacing out study sessions, often referred to as the spacing effect, significantly enhances retention of information. This phenomenon is based on the idea that when study sessions are distributed over time rather than crammed into a single session, it allows the brain to consolidate the information more effectively. Through spaced repetition, learners have the opportunity to revisit the material periodically, which helps to reinforce the connections in memory.

Moreover, the intervals between study sessions allow time for processing and reflection, which can enhance understanding and recall. Studies have consistently shown that individuals who space out their learning sessions perform better on tests of recall compared to those who study intensively over a short period. Thus, the spacing effect is a key strategy in cognitive psychology for improving long-term memory retention.
