3. The purpose of this study was to prove whether or not baby monkeys will attach themselves and develop love for what’s comforting to them over what nourishes them.
4. There were various other authors mentioned such as Gertrude van Wagenen, Thomas McCulloch and George Haslerud, who all reported cloth pads contact-need with monkeys and chimpanzees. However John B. Watson ignited such research with his opposing view that love was a innate emotion elicited by cutaneous stimulation of the erogenous zones.
5. a. The subjects were neonatal monkeys and infant monkeys. They were all chosen at random with no specific sex preferred.
b. The researchers observed that the infant monkeys preferred the cloth pads which were soft and more comforting verses the bare wire cage. Also they had discovered that monkeys raised on bare wire mesh cage floor survived with difficulty. Once they accumulated that data they decided to conduct an experiment to study the development of affection. They produced a wire mesh surrogate mother and a soft terry cloth surrogate mother and then observed the amount of time the monkeys spent with each mother per day. The control group in this experiment was the monkeys.
c. The data was collected via a line graph which illustrated the amount of hours the baby monkeys spent with each mother per day.
d. The researchers found that over time the subjects showed less responsiveness to the lactating wire mother and increasing responsiveness to the non-lactating cloth mother. They also found that comfort is of major importance in the development of affection or love, while lactation is a variable of negligible importance.
e. The author interpreted his findings to show that contact comfort was an important
