HANDLING OF PREGNANT RATS: EFFECTS ON EMOTIONALITY OF THEIR OFFSPRING

R ADER et al. Science. .

Abstract

Pregnant rats were either unmanipulated or were handled for 10 minutes three times daily throughout pregnancy. Offspring remained with their natural mothers or were crossfostered within and between experimental and control groups. When tested at 45 and 100 days of age, the offspring of handled mothers were found to be generally less emotional than the controls.
