Lasswell’s Model

Harold Lasswell, a political scientist, developed a communication model combining the main elements of communication. His model has been widely discussed since 1940s. He expressed the model as, “Who says what, in which channel, to whom, with what effect.” That means, Lasswell’s model of communication consists of four parts – who, what, channel, and whoa. Aristotle mentioned three of these four parts:- sender (who), message (what) and receiver (whom). Lasswell added only the component- channel. Most modern-day theorists discuss these four parts of the communication process by using different terms. The Lasswell’s model is shown below-

This model is about process of communication and its function to society, According to Lasswell there are three functions for communication:

  • Surveillance of the environment
  • Correlation of components of society
  • Cultural transmission between generation

Lasswell model suggests the message flow in a multicultural society with multiple audiences. The flow of message is through various channels.
