Introduction There is no doubt that the human brain can be considered as a very complex mechanism that allows people to complete a wide range of tasks in everyday life. In spite of that, things and processes that are difficult to understand have always attracted a lot of attention of the most prominent researchers in different fields. Speaking about people specializing in psychology, it is necessary to say that many of them were interested in studying the phenomenon of intelligence. Conducting their studies on the topic, researchers tried to understand the real nature of intelligence, further problems related to cognition, studying, and individual perception. In the twentieth century, famous researchers made their first attempts to understand the nature of intelligence and provide a final definition to this notion. Speaking about famous people who studied the discussed subject and made a significant contribution to further development of psychology, it is necessary to pay an increased attention to Gardner who proposed his theory of multiple intelligences in the 1980s. Analyzing and comparing different theories describing the notion of intelligence and factors defining its work, one can understand that theory developed by Gardner represents the most realistic interpretation of intelligence. Multiple Intelligences: The Theory by Gardner In reference to the topic of intelligence, it can be said that this aspect is believed to have been widely studied not only in people of different ages but also in various animals. Apart from that, the studies conducted on the topic allowed researchers to apply the principles of work of the human brain in order to develop a system that we call artificial intelligence. Speaking about the theory that was developed by Howard Gardner, it is important to note that his way to see intelligence and differences between people in this sphere was not supported by a wide range of researchers in the field initially. It was due to the fact that his vision seemed unusual to other people specializing in psychology. Nevertheless, it is necessary to say that the theory became extremely popular because of numerous opportunities to implement it into practice. As for the modern situation, the given theory is appreciated by those people related to education and by parents trying to reveal talents and strong suits of their children as soon as possible in order to help them to become more successful in the future. 1 Types of Intelligence According to the most important ideas outlined in the theory developed by the discussed researcher, intelligence is not something that should be considered as a unified whole. The author still supports such opinion despite the assumptions expressed by many other people related to the field. Many authors whose works appeared earlier than that of Gardner believed that intelligence was a process that was defined by only one ability. 2 Nevertheless, with the help of his work, Gardner proposed the notion of multiple intelligences that was in conflict with findings reported by previous researchers. Speaking about multiple intelligences and their importance, it is necessary to say that this notion helps to better understand a wide range of strong suits that different people possess. Having introduced this notion, Gardner singled out a range o
