Winch 1912¶

q2 · i? · causal · r1

Section-by-section comparison from Table III. The author notes the top section's superiority "is not due to some astonishing and quite abnormal work on the part of one individual, for every boy in this section of the afternoon group has beaten the corresponding boy", and asks whether strongly endowed children show the stimulating effect of the day's work.

"But the division of the groups into sections indicates that the afternoon workers in every section but the best do worse work in the afternoon than the corresponding sections in the morning."
