Repeated testing leads to better long-term retention than repeated study by reducing competition from related memories

Research from the Norman Lab further strengthens our understanding of the neural basis of learning

Published in, the Norman Lab reports that the neural signature of competition from rival memories can be detected during memory retrieval. This neural signature can be used to track competition levels across successive retrieval practice trials. 

The lab found that a drop in competition over these trials predicted long-term memory retention.
