q2 i? A 30-minute rest increased product per unit of time by about 5 percent and a night's rest by about 7 percent more, while accuracy remained almost exactly the same. → Edward L. Thorndike 1911

q2 · i? · causal · r1

In the same 72-subject mental multiplication experiment, rows done after a 30-minute rest and after a night's sleep showed further gains: "The rest of 30 minutes increased the prod- uct produced per unit of time by about 5%" and the night's rest about 7% more, with accuracy essentially unchanged.

"The rest of 30 minutes increased the prod- uct produced per unit of time by about 5%; the rest of a night in- creased the product by about 7% more. The accuracy of the work remained almost exactly the same."
