The Lasswell Model is one of the fundamental theories in the field of communication that establishes the key elements involved in the communication process. Developed by Harold D. Lasswell in 1948, this model offers a conceptual framework to understand how communication occurs and what factors are involved in this essential process for human interaction.
Background of the Lasswell Model
Harold D. Lasswell was a prominent researcher in the field of communication and political science, known for his contributions to communication theory. In his work "The structure and function of communication in society", published in 1948, Lasswell proposed a model that would become a fundamental reference in the study of communication.
The Model Lasswell's is based on the idea that communication is a complex process that involves various interrelated elements. Lasswell posed a central question that summarizes the essential components of communication: "Who says what through what channel to whom and with what effect?" This question became the basis of the model and guides the understanding of the elements involved in communication.
Elements of the Lasswell Model
1. Who
The first element of the Lasswell Model refers to the sender or source of the communication. In every communication process, there is a person or entity that initiates the act of communication, that is, the one who transmits the message. The sender can be an individual, a group or an organization that intends to send information or influence the audience.
2. What
The second element of the model focuses on the message, that is, what is communicated. The message is the information that the sender wishes to transmit to the receiver. It can be composed of words, images, gestures, symbols or other elements that carry meaning and are used to express an idea, an emotion or a concept.
3. Through which channel
The third element of the model refers to the communication channel, that is, the medium through which the message is transmitted. It can be oral, written, visual, digital, among others. The channel used can influence the way the message is perceived and interpreted, which is why it is a relevant aspect in the communication process.
4. To whom
The fourth element of the model focuses on the receiver or recipient of the communication. It is the person or group that receives the message sent by the sender. The receiver plays a fundamental role in communication, since he is the one who interprets and decodes the information received. The effectiveness of communication depends largely on the recipient's ability to understand the message.
5. With what effect
The last element of the model refers to the effect of the communication on the receiver. Lasswell highlighted the importance of considering the impact the message has on the audience. Communication can generate different responses, emotions or changes in the behavior of the recipient, so it is essential to evaluate how the transmitted information will be received and processed.
Applications of the Lasswell Model
The Lasswell Model has been widely used in various fields of study, including communication, advertising, politics and psychology. Its focus on the fundamental elements of communication has allowed us to better understand communication processes and improve the effectiveness of the messages transmitted.
In the field of advertising, for example, the Lasswell Model is used to design effective campaigns that manage to impact the desired audience. By analyzing who the sender is, what is being communicated, through what channel, to whom it is addressed and with what effect, advertisers can create persuasive and relevant messages.
In the field of politics, The Lasswell Model is used to study the influence of political messages on public opinion and the behavior of citizens. Understanding who issues communications, what is communicated, through what means, to whom it is directed and with what consequences, allows us to analyze the impact of political communication on society.
Criticisms of the Lasswell Model
Despite its relevance and usefulness, the Lasswell Model has also been the subject of criticism and questioning by some researchers in the field of communication. One of the most common criticisms is that the model oversimplifies the communication process by reducing it to five basic elements, which may not reflect the real complexity of human communication.
In addition, it is argued that the model It does not consider aspects such as cultural context, emotions, interpersonal relationships or communicative noise, which also influence the way communication is produced and interpreted. Therefore, some scholars suggest that the model could be enriched by integrating these and other relevant elements.
Conclusions
The Lasswell Model continues to be a valuable tool for understanding the essential elements of communication and its influence on society. Although it has been the subject of criticism and debate, its focus on the fundamental aspects of the communication process remains relevant today.
By considering who sends the communication, what is transmitted, through what channel, to who is addressed and with what effect, it is possible to more completely and systematically analyze the messages sent in different contexts and evaluate their impact on the audience. The Lasswell Model offers a solid conceptual framework that continues to be very useful in the study and practice of communication.
