He abandoned his research into maternal attachment and developed an interest in isolation and depression. Harlow's first experiments involved isolating a monkey in a cage surrounded by steel walls with a small one-way mirror, so the experimenters could look in, but the monkey could not look out. The only connection the monkey had with the world ...
Monkey clinging to the cloth mother surrogate in fear test. Harry Frederick Harlow (October 31, 1905 – December 6, 1981) was an American psychologist best known for his maternal-separation, dependency needs, and social isolation experiments on rhesus monkeys, which manifested the importance of caregiving and companionship to social and cognitive development.
Harlow, being fascinated with the concept of love and nurturing, worked with monkeys to test these theories. (Berger, 2005) In Harlow's monkey experiment, newborn monkeys were separated from their mothers almost immediately after birth. They were then raised with substitute "mothers" made of either (1) wire or (2) wood covered with a soft cloth.

[ 36 ] [ 37 ] Writing on the researcher's legacy, John Gluck, a former student of Harlow's opined, "On the one hand, his work on monkey cognition and social development fostered a view of the animals as having ...
The formal origin of attachment theory can be traced to the publication of two 1958 papers, one being Bowlby's The Nature of the Child's Tie to his Mother, in which the precursory concepts of "attachment" were introduced, and Harry Harlow's The Nature of Love, based on the results of experiments which showed, approximately, that infant rhesus ...
Suomi describes his current research interests as focusing on the role of genetic and environmental factors in shaping individual psychological development in non-human primates; the effect of change on psychological development; and whether findings on monkeys in captivity can translate to monkeys living in the wild, and between human beings of different cultures.

The baby monkey would choose to snuggle up to the cloth mother and felt secure. If the experiment was performed again without the cloth mother then the baby monkey would freeze up, scream, and cry. This study shows a secure attachment to something that is soft and comforting. Babies can feel the same way with blankets or stuffed animals. [14]
