Love in Infant Monkeys

HARRY HARLOW HAD A general hypothesis: Mothers are useful, in scientific terms. They have an intrinsic value, even beyond their breast milk. Call it their company.

In this hypothesis he was bucking a trend in American psychology. For decades experts on parenting had been advising mothers to show their children as little affection as possible. Too much affection was coddling, and coddling weakened a child. “When you are tempted to pet your child,” said a president of the American Psychological Association in a speech, “remember that mother love is a dangerous instrument.” This school of thought ran counter to what was believed by those not indebted for their child-rearing strategies to a rigorously monitored testing process. But it was dominant in the scholarship. To refute it, Harlow decided, the value of love would have to be demonstrated in a controlled experimental setting.

He worked long hours, seldom leaving his laboratory. With his experiments he made a name for himself, appearing on television programs and traveling the country on speaking engagements. He was seen as a rebel and an iconoclast. He spoke boldly of mother love, calling it “contact comfort.” He stressed its value to emotional health.

But he spoke harshly of his test subjects. “The only thing I care about is whether a monkey will turn out a property I can publish,” he said. “I don’t have any love for them. I never have. How could you love a monkey?”

To know how love works, a scientist must study its absence. This is simple scientific method; Harry admitted it. The suffering of lesser beings is often the price of knowledge. As he put it, “If my work will save only one million human children, I can’t get overly concerned about ten monkeys.”

Others were doing bold animal experiments at the same time, in the fifties, when Harry started, and after. Rats were dropped in boiling water, cats pinned down for months until their legs withered, dogs irradiated until their skin crisped, monkeys shot in the heads and stomachs or immobilized to have their spinal cords severed. When it came to the treatment of research animals, Harry was squarely in the mainstream. Only his willingness to speak bluntly was avant-garde.

He gathered disciples around him, young women and men who would continue his work, and decades later he would still be revered by psychology. While acknowledging the problem of what some might call animal cruelty, later scholars would view his collateral damage as a necessary unpleasantness. His chief biographer, a woman journalist, described him as a rose in a cornfield.

He was a high-functioning alcoholic, and there were long periods in his life when he was rarely sober. He had wives—first one, then another, then the first one again. He had two sets of children he never saw.

Harry Frederick Harlow had been born Harry Frederick Israel. Around the time of his doctoral dissertation he had changed his last name, not because he was Jewish—for he was not, in fact, Jewish—but because the name Israel sounded Jewish, and this made it hard to secure a good job. He did not dislike Jews; indeed, he admired them for their intelligence and their education. But others in academia had certain prejudices. A famous professor who was also his first mentor did not wish him to continue to be mistaken for a Jew, so Harry deferred to him.

It was a minor accommodation.

One way to prove the hypothesis was to take a newborn monkey away from its mother and never give it back. Put it in a bare box, observe it. Anxiety first, shown in trembling and shaking; then come the screams. Watch it huddle, small limbs clutching. Make careful notations. Next, construct a wire mannequin that holds a milk bottle. See if the baby thinks the mannequin is its mother. When it does not think so, give it a mannequin draped with terry cloth, but no milk. See it cling to this milkless cloth mannequin.

Repeat experiment with numerous infants. Make notations.

Second, place infant monkeys in isolation, with neither monkey nor human contact save the sight of the researchers’ hands entering the box to change bedding or food. Leave them there for thirty days. Make careful notations. When the infants are removed, watch two among them starve themselves till they expire. Notations. Repeat with longer isolation periods. First six months, then a year. If necessary, force-feed upon removal from box. Observe: If left in boxes for twelve months, infants will no longer move. Only life signs: pulse and respiration. Upon removal from box, such damaged infants may have to be reisolated for the duration of their short lives. Notations.

Third, attempt to breed the isolate monkeys to produce needed new experimental subjects. When the monkeys show no inclination to mate, inseminate the females. Observe the birth of infants. Observe that the longest-isolated mothers kill infants by chewing off fingers and toes or crushing heads with their teeth. Notations.

Fourth, create bad-mother surrogates: mothers with spikes, mothers that blast cold wind. Put baby monkeys on them. Observe: Time after time, baby monkeys return. Bad mother is better than none.

Only 8:00 pm, and he was already slurring. He would swing by that party. What the hell. Suomi had said he’d be there.

But first, check the experiments.

Walking along the row of vertical chambers, he gave cursory glances inside—one, two, three subjects in a row had given up trying to climb out of their wells of isolation. The pits were designed, of course, to make it impossible to escape.

One subject scrambled and fell back, a weak young female. She looked up with her great round black eyes. Blink blink. She was afraid, but still plucky. Still game to try to get out, change her situation. The others were abject at the bottom of their separate holes, knew by now they could never climb the sides of the wells. As far as they knew, they were in there for good. Plucky got you
