the impact of early maternal deprivation could be reversed in monkeys only if it had lasted less than 90 days
, and estimated that the equivalent for humans was six months.

Half of the monkeys were able to get milk from the wire mother and the other half got milk from the cloth mother. This experiment lasted
165 days
