Expectancy–value theory has been developed in many different fields including education, health, communications, marketing and economics. Although the model differs in its meaning and implications for each field, the general idea is that there are expectations as well as values or beliefs that affect subsequent behavior.
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.
Value theory is the interdisciplinary study of values.Also called axiology, it examines the nature, sources, and types of values.Primarily a branch of philosophy, it is an interdisciplinary field closely associated with social sciences like economics, sociology, anthropology, and psychology.
Value in marketing, also known as customer-perceived value, is the difference between a prospective customer's evaluation of the benefits and costs of one product when compared with others. Value may also be expressed as a straightforward relationship between perceived benefits and perceived costs: Value = Benefits - Cost .
One key activity in communication theory is the development of models and concepts used to describe communication. In the Linear Model, communication works in one direction: a sender encodes some message and sends it through a channel for a receiver to decode. In comparison, the Interactional Model of communication is bidirectional. People send ...
The term Social Information Processing Theory was originally titled by Salancik and Pfeffer in 1978. [4] They stated that individual perceptions, attitudes, and behaviors are shaped by information cues, such as values, work requirements, and expectations from the social environment, beyond the influence of individual dispositions and traits. [5]
The value function that passes through the reference point is s-shaped and asymmetrical. The value function is steeper for losses than gains indicating that losses outweigh gains. Prospect theory stems from loss aversion, where the observation is that agents asymmetrically feel losses greater than that of an equivalent gain. It centralises ...
George Gerbner, the founder of the cultivation theory, expanded Lasswell's model in 1956 to focus "attention on perception and reaction by the perceiver and the consequences of the communication". [19] Laswell's 5W model of communication was expanded by Richard Braddock into a 7W model in his 1958 paper "An Extension of Lasswell's Formula".
