The little Albert experiment proved that psychological fears could be influence by classical conditioning. Little Albert, an infant, was first shown a white rat. At first, he was not afraid of the white rat. However, John Watson, leader of the experiment, presented the white rat repeatedly with a frightening high pitched noise (unconditioned stimulus) which scared little Albert (the unconditioned response). After five times, the infant became frightened whenever the white rat was presented (conditioned response). The white rat was what he associated with the fear of the loud noise and was now the conditioned stimulus.
John B. Watson
Born 9MAR1919. After the experiment, he was sent home back to his mother. Around this time he was 8 months and 26 days old. On 10MAY1925 he later died of hydrocephalus (water in the brain). It is now believed that Little Albert was disabled at birth and Dr. Watson knew so. His experiment has been declared null and void due to these new findings.
Initially, little Albert wanted to touch and play with the rat. However, each time he tried he heard a loud clanging sound. This lead to Albert not wanting to play with the rat, and eventually to be frightened of it. This is connected to conditional learning, as Albert was conditioned to fear the rat through punishment.
To make an experiment valid you have to make sure that the experiments results answer the question that you first started from.
A loud noise
John B. Watson
Watson and Rayner's experiment with little Albert had a number of ethical issues. The most important is harm to the participant. Albert was subjected to loud clanging noises and was made to develop a phobia. He also did not give informed consent as he was only a very small child. For these reasons, the experiment would not be performed today.
controlled results stay the same in an experiment
The results of an experiment are called your data.

An experiment in which the results are repeatable....apex
The outcome of an experiment is a "conclusion", the interpretation of the results compared with the expected results and the goal of the experiment.
A disadvantage of a vitro experiment is that the results can be misleading.
The results of a science experiment do not have to match the original hypothesis. Indeed, the results collected in an experiment may be completely different to those that the scientist predicted.
There is no definitive response that can be given because there were two variables in the experiment that could lead to different conclusions.
Observations and measurements made during an experiment are called the data.
