Harlow went so far as to say he had not feelings for the monkeys.

Harlow’s Classic Studies Revealed the Importance of Maternal Contact

Total social isolation involved rearing monkeys in isolation chambers that precluded any and all contact with other monkeys. Psychologically speaking, these infants were slightly strange: One might presume at this point that they find their situation to be hopeless.

In one instance, a mentally ill inmate at the Tamms supermax prison in Illinois declined to the point where he mutilated his own genitalia. In the first, the wire mother had a milk bottle and the cloth mother did not; in the second, the cloth mother had the food while the wire mother had none.

He found that, just as they were incapable of having sexual relations, they were also unable to parent their offspring, either abusing or neglecting them. Isolation in monkeys like to think that out of every bad situation, something good is derived from it.

The four monkeys who suffered isolation, either partial or total, were tested as a group of four in playroom situations, like the one here: The paper described briefly that for the past ten years the paper was published inHarlow and his team were studying the effects of partial isolation.

Although Harlow, his students, contemporaries, and associates soon learned how to care for the physical needs of their infant monkeys, the nursery-reared infants remained very different from their mother-reared peers.

The autopsy report attributed death to emotional anorexia. If anything, Harlow was detail-oriented and determined to not let confounds in his experiment. Harlow wrote, "most subjects typically assume a hunched position in a corner of the bottom of the apparatus.

It was through these studies that Harlow discovered that the monkeys he worked with were developing strategies for his tests. Harlow and Mears divorced in When placed in a novel environment with a surrogate mother, infant monkeys would explore the area, run back to the surrogate mother when startled, and then venture out to explore again.

Harlow married his first wife, Clara Mears, in One might presume at this point that they find their situation to be hopeless. If frightened, the infant ran back to the surrogate mother and clung to her for a time before venturing out again. They tend to do well, I believe.

Investigators have measured a direct, positive relationship between the amount of contact and grooming an infant monkey receives during its first six months of life, and its ability to produce antibody titer IgG and IgM in response to an antibody challenge tetanus at a little over one year of age.

The infants were assigned to one of two conditions.

In the paper, Total Social Isolation in Monkeys, the team sought to go one step further: When the isolated infants were re-introduced to the group, they were unsure of how to interact — many stayed separate from the group, and some even died after refusing to eat.

In the last of these devices, alternatively called the "well of despair", baby monkeys were left alone in darkness for up to one year from birth, Isolation in monkeys repetitively separated from their peers and isolated in the chamber. Stuart Grassian, a board-certified psychiatrist and a former faculty member at Harvard Medical School, has interviewed hundreds of prisoners in solitary confinement.

Total social isolation was now the name of the game. Going back to the paper. Yes, his experiments were that bad.These monkeys were then observed in various settings.

For the study, some of the monkeys were kept in solitary isolation for 15 years. In the total isolation experiments, baby monkeys would be left alone for three, six, 12, or 24 months of "total social deprivation". The experiments produced monkeys that were severely psychologically disturbed.

What happens when you make a baby monkey choose between food and comfort? The Harlows answered this question in a series of primate experiments. Four 6-month isolate monkeys were individually housed for 2 weeks after removal from the isolation chambers.

Total social isolation was now the name of the game. The total isolation was achieved by housing the monkeys only a few hours after their birth in stainless-steel chambers, like this one.

Harlow had already placed newly born monkeys in isolation chambers for up to one year. With the pit of despair, he placed monkeys between three months and three years old in the chamber alone, after they had bonded with their mothers, for up to ten weeks.

Within a few days, they had stopped moving about and remained huddled in a corner. Harlow also found that monkeys kept in isolation wound up “profoundly disturbed, given to staring blankly and rocking in place for long periods, circling their cages repetitively, and mutilating.
