An onion model used in social penetration theory. The onion model is a graph-based diagram and conceptual model for describing relationships among levels of a hierarchy, evoking a metaphor of the layered "shells" exposed when an onion (or other concentric assembly of spheroidal objects) is bisected by a plane that intersects the center or the innermost shell.
Shannon–Weaver model of communication [86] The Shannon–Weaver model is another early and influential model of communication. [10] [32] [87] It is a linear transmission model that was published in 1948 and describes communication as the interaction of five basic components: a source, a transmitter, a channel, a receiver, and a destination.
Some theorists hold that Lasswell's model is too simple to be called a model of communication and is better characterized as a questioning device. [10] Against this view, it has been argued that the model's simple presentation in terms of five questions is a convenient starting point but does not do justice to its theoretical complexity. [2]
Both depth and breadth are related to the onion model. As the wedge penetrates the layers of the onion, the degree of intimacy and the range of areas in an individual's life that an individual chooses to share increases. The breadth of penetration is the range of areas in an individual's life being disclosed, or the range of topics discussed.
Communication theory is a proposed description of communication phenomena, the relationships among them, a storyline describing these relationships, and an argument for these three elements. Communication theory provides a way of talking about and analyzing key events, processes, and commitments that together form communication.
Schramm's model of communication was published by Wilbur Schramm in 1954. It is one of the earliest interaction models of communication. [1] [2] [3] It was conceived as a response to and an improvement over earlier attempts in the form of linear transmission models, like the Shannon–Weaver model and Lasswell's model.

The SMCR model is usually described as a linear transmission model of communication. [4] [17] Its main focus is to identify the basic parts of communication and to show how their characteristics shape the communicative process. In this regard, Berlo understands his model as "a model of the ingredients of communication". [24]
