Intensive parenting is a style of child-rearing fit for an age of inequality, indicative of a stratified past, present, and future.

Differential rearing was not associated with differences in basal or stress-related plasma cortisol, although these levels did progressively decline as monkeys matured.

Rearing condition was a stronger predictor of body weight than treatment, because a significant interaction between rearing condition (AR-MIN, AR-MAX, MR-CON) and time (p < 0.001) was found.
