Abstract Rats were reared during the first 3 weeks of life in a group or singly, with the mother rat or in an incubator with no maternal contact. Variations in early experience were assessed in terms of adrenal steroid functioning when the animals were 1‐yr old. Whether they were reared in a group or individually, incubator‐reared animals were found to have significantly higher basal and stress levels of plasma corticosterone. In addition, their corticosterone response to stress was greater regardless of initial levels.
