Answer:
B. that it was possible to condition an emotional reaction to a previously neutral stimulus.
Explanation:
The "Little Albert" experiment was a controlled experiment that took place at John Hopkins University in 1920. This experiment tried to establish whether classical conditioning could be used to condition a child to fear a stimulus that normally would not be feared by a child. The experiment wanted to demonstrate that it was possible to condition an emotional reaction to a previously neutral stimulus. Although the experiment was considered to have been successful at the time, it has been criticized in recent years.
