Summary of the Classic Psychology experiments
There are several psychological experiments, which have beendeveloped by different scholars. One of these is the Harlow’sRhesus Monkey Experiment. It was pioneered by Harry Fredrick Harlow,who was an American psychologist, born in 1905. He was laterstationed at Henry Villas Zoo, where he used nonhuman primate, tostudy dependency need, maternal-separation and social isolation. Tostudy cognition, memory and learning, he developed Wisconsin GeneralTesting Apparatus (WGTA) and separated infant primates from theirmothers. These infants showed some social deficits compared to theircounterparts. His aim was to determine the importance of a mother inrearing children. He conducted several studies in relation tomaternal care. His conclusion was that physical contact between amother and a child is important, for child development.
The second experiment is the Monster Study which was done by WendellJohnson, through Tudor, who was one of his students in the Universityof Iowa. It was referred to as stuttering experiment. It involvedtwenty two children who were selected randomly in the city ofDavenport, Iowa. The aim was to induce stuttering to the healthychildren and determine if there were any changes in their speeches.There were ten orphans who were stutterers in the group. Tudordivided all children into different groups and subjected them todifferent psychological stimuli. Together with her five students, shelistened to each child occasionally, for five months. There werepsychological changes to the children, which made Johnson concludethat in most cases, stuttering starts from mothers, not from achild’s mouth.
The third experiment was the Landis Facial Expressions Experiment.In 1924, Carney Landis, who was a psychologist in the University ofMinnesota, carried out an experiment to determine the relationshipbetween facial expression and emotions. He painted a group of hisstudents’ faces with black lines, to make their facial musclesclear, as they reacted to different stimuli, including beheadingrats. He did not get the results he expected, but his conclusion wasthat human beings were ready to do what they were asked to.
