While scientists have done a tremendous number of studies of distributed practice, many fundamental questions about distributed practice remain poorly understood.
We don't understand in detail why exponential decay of memory occurs, or when that model breaks down. We don't have good models of what determines the rate of decay, and why it varies for different types of memories. We don't understand why the decay takes longer after subsequent recalls. And we have little understanding of the best way of expanding the inter-study intervals.
