ABSTRACT
The “Spacing Effect” is one of the longest and most enduring findings in cognitive psychology. It was first detailed in 1885 by German psychologist Hermann Ebbinghaus who found that humans tend to forget large amounts of information if they only learn something once. Since then, research has consistently shown the power of spacing out your learning (#66). This is an effective technique, as it allows time for the material to be forgotten and re-learnt. This process can help a student cement this knowledge into their long-term memory.
