Answer:
Law of Effect.
Explanation:
Edward L. Thorndike (1874-1949) was an American psychologist and researcher, and one of the pioneers of behavioral psychology. Thorndike's experiments with cats led him to discover a psychological pattern he called the Law of Effect. According to this law, if faced with similar or recurring situations, we tend to repeat the behaviors that resulted in satisfying or positive consequences, while we don't tend to repeat the behaviors that resulted in unpleasant or negative consequences. One application of this principle was a learning method based on rewards and punishments called operant conditioning, developed by another well-known American psychologist and author, B. F. Skinner, in the early 20th century.
During the era of slavery in the United States, the education of African Americans, enslaved and free, was often discouraged, except for religious instruction, and eventually made illegal in many of the Southern states. It was believed that literacy was a threat to the institution of slavery. First, literacy facilitated knowledge about the successful slave revolution in Haiti of 1791–1804, the end of slavery in the British Empire in 1833, and the writings of abolitionists. Secondly, literacy allowed or potentially allowed slaves better access to information about the Underground Railroad and other routes to freedom.
