Lag Effect

Students were retaught english-german vocabulary after lags of 0,1, or 10 days and tested 35 days later. 

When vocabulary was tested, students from lags of 1 or 10 days performed better than those from 0 lag. 

We reatin information better when there are longer breaks in between presentations of the same information.
