The Psychologist
Name: Harry Harlow

The Monkey Love Experiment studied various aspects:
Child growth and social development
Harry Harlow was interested in the concept of love and what caused it.
Between a mother and infant/young child

Theories of Love
During the 1960s, it was thought that the reason there was an attachment between mother and child was because the mother provided:
Nutrition (Food & Drink) for the child
Warmth and safety
Pain Reliever

Harry Harlow believed this was an insufficient explanation of attachment so he designed the MONKEY LOVE EXPERIMENT.
The Experiment
Rhesus Monkeys- Infants/Young
Built Two Surrogate Mothers-
#1.) Made of wire with a baby bottle filled with food
#2.) Made of terry-cloth, no food
1.) Infant monkeys are separated from mothers a few hours following birth, both mother and infant react in anger and violence
2.) Infants are put in an cage to be raised by the surrogate mothers
Terry Cloth
Two Mothers
The Subsequent Experiments- Iron Maiden & Well of Despair
Observation #1
Infant Rhesus Monkey significantly lingered more around the terry cloth mother.

Meaning & Interpretation

Comfort is more important to the infant than food
Attachment is not caused because of an infant's need to quench hunger and thirst
Love grows from touch not taste
Meaning & Interpretation
The needs of an infant are much more complicated than replenishing hunger
The first face an infant sees is the most beautiful, the one they love
Scenario #2
Observation #2
Infant embraced and admired the blank faced mother
The baby monkey reacted in horror when the new face was attached
Reactions- screaming, rocking, and clutching themself
Harry Harlow wished to design a surrogate mother (terry cloth) with a more appealing, pretty face. However, it was not done in time for the new infant. The surrogate monkey had a blank face. Later, the new head with features was attached.
The Problems
Problems with the surrogate raised monkeys in the Monkey Love Experiment:
Infant monkeys abused themselves, were antisocial, and emotionally disturbed
Females attacked males- no sexual interaction
Females could not reproduce normally. If they produced children, they killed them
Four Variables of Love
Touch- critical
Contact Comfort- essential component

Nursing was no longer recognized as a variable of love.
The Results & Conclusion
Iron Maiden
Harry Harlow designed another surrogate mother.
The Iron Maiden-
Shot out sharp spikes
Dispensed a super strong cold air
Rattled their child
Some killed the infant
Caused the baby monkey to scream and be frightened

Observation: Infant monkeys remained attached to the surrogate.
Well of Despair
Harry Harlow designed a Well of Despair:
Isolation chamber
Animals were hung upside down for a maximum of two years
Unable to see the outside world
Fed through a grid on the bottom of the cage

Animals were mentally ill and psychotic with no such cure for their condition. This demonstrated effects of social isolation
Harlow's experiments made a huge impact on people's understanding of maternal deprivation and child development
The most important thing to ensure a normal child's development is comfort and safety
The experiments are thought to be controversial and inhumane
Increased awareness of animal cruelty
Received numerous awards such as the National Medal of Science ('67) and the gold medal from the A.P.A. ('73)
