The spacing effect, if not the most studied learning factor, is certainly in the top five. As Harry Bahrick and Lynda Hall said in 2005, “The spacing effect is one of the oldest and best documented phenomena in the history of learning and memory research.”
The spacing effect is the finding that repetitions that are spaced over time produce better long-term remembering than the exact same repetitions spaced over a shorter amount of time or massed all together.
About 10 new scientific studies are carried out each year on the spacing effect (I counted 31 in the last three years). Why such frenzied dedication to exploring the spacing effect? Scientists want to know what causes it! It's really rather fascinating!
