An illustration of the domino theory as it had been predicted
The domino theory was a theory prominent from the 1950s to the 1980s that posited that if one country in a region came under the influence of communism, then the surrounding countries would follow in a domino effect.[1] The domino theory was used by successive United States administrations during the Cold War to justify the need for American intervention around the world.
U.S. President Dwight D. Eisenhower described the theory during an April 7, 1954, news conference, when referring to communism in Indochina:

It is a cognitive system which receives the information collected by a person's senses and manipulates it for processing or for elaborating responses in the short run. Is crucial for reasoning and for the decision making processes that shape attitudes and behaviour.
The working memory is the intermediate step between the short term memory, where the information collected is immediately available for a short time not processed, and the long-term memory (LTM), where information is stored definitely.
