Evidence

Pechstein, L. A. (1921). Massed vs. Distributed Effort in Learning. The Journal of Educational Psychology. https://doi.org/10.1037/h0070137

q2 · i? · causal · r1

The author's fourth conclusion from the maze experiments, stated in the results discussion of Table I: whole-method learning of a difficult maze is uneconomical under either temporal distribution, so the part method with massed effort is advised.

"Fourth, the longer and more difficult the problem, the more advisable to break it up into units and learn both the units and the connection of these under massed conditions, it being uneconomical to learn the hard problem as a whole, irrespective whether effort is massed or distributed."
