The Little Albert Experiment by John Watson and Rosalie Rayner

Little Albert's experiment was a well-known case study and discussed by many psychologists. In 1920, activist John Watson and his assistant Rosary Leiner began their first experiment with their children. In this case study, Mr. Watson wants to minimize injuries during the experiment, so stability is the main factor in choosing Albert. The Watson approach in this experiment was to use the principle of classical conditioning to create a child's stimulus that would lead to fear.

1920 - John B. Watson and his assistant Rosary Leiner will experiment with the classical conditioning of children. In many cases, research by Watson and Reiner, called Little Albert's study, suggests that children may be stimulated by the fear that they were not afraid of the front. This research is impossible today because of ethical safeguards. 1922 - Abigail Adams Elliott, with the help of Mrs. Henry Greenleaf Pearson, founded Ruggles Street kindergarten in Rocksbury, Massachusetts, one of the earliest educational kindergartens in the United States. It became Elliott - Pearson Children's School and is now part of Child Development Department at Elliott - Pearson Tufts University.

Experimental details: The Little Albert experiment is considered as one of the most unethical psychological experiments ever. The experiment was conducted by John Watson and Rosary Leiner of Johns Hopkins University in 1920. Hypothesis is that through a series of pairs, they can investigate children in nine months to develop irrational fear. The experiment began with placing a white mouse in front of a baby who was not worried about animals at first. Whenever Albert is sent to the mouse, Watson will hit the steel bar with a hammer and make a loud noise. Whenever the mouse appeared in the room, after several pairs (noise and white mouse playing) the boy started to cry and showed signs of fear. Until Albert is concerned about them all, Watson created conditioning similar to other common animals and things (rabbits, beat of Santa Claus etc)

In 1920, activist John B Watson and his assistant Rosary Leiner performed experiments called "Little Albert". The ideal result of this experiment is empirical evidence of human classical conditional reflex. (T. Bartlett) Russian physiologist Ivan Pavlov did a similar study before "Little Albert" which proved the dog's conditioning process. It is said that Watson wants to continue Pavlov's research and make further progress, and finally it shows that the emotional reaction may be a typical state of humans. Watson and Rayner first chose a nine month old baby from a local hospital whose name is Douglas Merritte.
