This study examined longitudinally whether early differences in reactivity to stress are related to self‐recognition at 18 months of age. Adrenocortical and behavioral to Stress responses to routine inoculation at 2, and 4 months and at 6 and 18 months were obtained. Previous finding indicated a development shift in adrenocortical functioning by 6 months of age that included the emergence of stable individual differences in cortisol response from this point in development. Self‐recognition was related to greater cortisol response and less rapid quieting at 6 to 18 months, whereas 2‐ to 4‐month cortisol and quieting response did not differentiate self‐recognizers and non‐self‐recognizators. These findings indicate a role for temperament differences in facilitating the emergence of self‐recognition.
