Age of weaning in two subspecies of deer mice.

Weaning age in deer mice is defined as the age at which the young mice maintain or gain weight during a 24-hour period of isolation; mice younger than weaning age lose weight. Two subspecies of deer mice differed in weaning age; the age for Peromyscus maniculatus bairdii was 18 days; for P. m. gracilis, 24 days. Age and food consumption were better predictors of the weaning condition, as defined in terms of weight change with isolation, than body weight.

Critical period in the social development of dogs.

Litters of puppies were isolated, with the bitch, in fenced acre fields from 2 to 14 weeks of age. They were removed indoors at different ages, played with for a week, and returned to the field. The pups manifested an increasing tendency to withdraw from human beings after 5 weeks of age and unless socialization occurred before 14 weeks of age, withdrawal reactions from humans became so intense that normal relationships could not thereafter be established
