Abstract

In Experiment 1 rabbits were handled for the first 10 days of life while controls were not disturbed. In Experiment 2 rabbits were handled on Days 11–20. In Experiment 3 rabbits were handled on Days 1–10, 11–20, 1–20, or were not handled. Starting at 31 days the animals were given an open‐field test, a test for exploratory behavior toward novel stimuli, and a test of social behavior. The data were not consistent with the critical period concept. Instead, handling during the first and second 10‐day intervals appears to be additive and to approximate the effects of 20 days of handling.
