Synopsis
Excerpt from Individual Differences and Family Resemblances in Animal Behavior: A Study of Habit Formation in Various Strains of Mice
Preliminary tests were made with albino rats, but later mice, which are more active and more easily handled, were substituted. The mice were given one trial each day at as nearly the same time as possible. Light was found to play but a minor mile in the tests, day light and artificial light serving equally well. At the outset the age of the mice when first tested was not always known, but later, when the various litters were obtained, the young mice were tested at, or about, the age of four weeks.
