Many models of communication include the idea that a sender encodes a message and uses a channel to transmit it to a receiver. Noise may distort the message along the way. The receiver then decodes the message and gives some form of feedback. [1] Models of communication simplify or represent the process of communication.
The communication skills required for successful communication are different for source and receiver. For the source, this includes the ability to express oneself or to encode the message in an accessible way. [8] Communication starts with a specific purpose and encoding skills are necessary to express this purpose in the form of a message.
For example, teachers may share and explain information while students may listen and ask clarifying questions. As the background of communication, the relation also affects how the messages are interpreted. For example, seeing a person as an actor on a stage leads to one interpretation of their messages.
Many later theorists expanded this model by including additional elements in order to take into account other aspects of communication. For example, Wilbur Schramm includes a feedback loop to understand communication as an interactive process and George Gerbner emphasizes the relation between communication and the reality to which the ...
In regard to self-defense, communication is used to warn others and to assess whether a costly fight can be avoided. [167] Another function of communication is to mark and claim territories used for food and mating. For example, some male birds claim a hedge or part of a meadow by using songs to keep other males away and attract females. [168]
Because it treats various basic concepts of communication, some scholars also refer to it as "Lasswell's definition" and some dictionaries even make reference to Lasswell in their definitions of communication. [2] Zachary Sapienza et al. hold that there are many different conceptions of Lasswell's model, given both by himself and by other ...
Communication – purposeful activity of exchanging information and meaning across space and time using various technical or natural means, whichever is available or preferred. Communication requires a sender, a message, a medium and a recipient, although the receiver does not have to be present or aware of the sender's intent to communicate at ...
The receiver has to decode the message in order to understand it. [9] [10] However, as many subsequent communication theorists have pointed out, linear transmission models are too simple to account for all forms of communication. In regular face-to-face conversation, for example, there is usually no designated sender and receiver.
