Communication, as a fundamental element of human interaction, encompasses a wide spectrum of aspects ranging from verbal to non-verbal communication. Persuasion is a key concept within communication, which implies the deliberate use of various strategies and techniques to influence the opinion, attitudes or behavior of others. Signs in communication play a key role in conveying messages, where verbal and non-verbal signs together shape the meaning of communication. Symbolic reality is a theoretical framework that explores how symbols shape our perception of reality and thus our communication. Manipulation in communication is deeply related to persuasion, and it is often used to achieve the desired reaction in the recipient of the message. This may include distortion of information, emotional manipulation, or veiled suggestion. Subliminal messages are a special form of manipulation, including messages or symbols that are presented in an imperceptible way, usually below the threshold of consciousness, with the aim of influencing the behavior or decisions of the recipient. In the context of the final thesis, the research of these terms is crucial for understanding the deeper mechanisms of communication. Analyzing how signs and symbols shape the perception of reality and how they are used for persuasive purposes is important for understanding the complexity of human interaction. Also, the study of manipulation and subliminal messages provides insight into potential risks and numerous ethical issues that may arise in all phases of communication processes. In conclusion, communication is a deeply complex phenomenon involving persuasion, signs, symbols, manipulation and subliminal messages. Their interaction shapes the way we understand the world around us and how we act in it. Understanding these concepts is crucial to any analysis of communication and can have wider implications in areas such as marketing, politics and social interactions.
