In communications and information processing, code is a system of rules to convert information—such as a letter, word, sound, image, or gesture—into another form, sometimes shortened or secret, for communication through a communication channel or storage in a storage medium. An early example is an invention of language, which enabled a person, through speech, to communicate what they thought, saw, heard, or felt to others. But speech limits the range of communication to the distance a voice can carry and limits the audience to those present when the speech is uttered. The invention of writing, which converted spoken language into visual symbols, extended the range of communication across space and time.
Herbert Marshall McLuhan was a Canadian philosopher whose work is among the cornerstones of the study of media theory. He studied at the University of Manitoba and the University of Cambridge. He began his teaching career as a professor of English at several universities in the United States and Canada before moving to the University of Toronto in 1946, where he remained for the rest of his life. He is known as the "father of media studies".
Media ecology theory is the study of media, technology, and communication and how they affect human environments. The theoretical concepts were proposed by Marshall McLuhan in 1964, while the term media ecology was first formally introduced by Neil Postman in 1968.
The sensory nervous system is a part of the nervous system responsible for processing sensory information. A sensory system consists of sensory neurons, neural pathways, and parts of the brain involved in sensory perception and interoception. Commonly recognized sensory systems are those for vision, hearing, touch, taste, smell, balance and visceral sensation. Sense organs are transducers that convert data from the outer physical world to the realm of the mind where people interpret the information, creating their perception of the world around them.
Understanding Media: The Extensions of Man is a 1964 book by Marshall McLuhan, in which the author proposes that the media, not the content that they carry, should be the focus of study. He suggests that the medium affects the society in which it plays a role mainly by the characteristics of the medium rather than the content. The book is considered a pioneering study in media theory.
A sensorium (/sɛnˈsɔːrɪəm/) is the apparatus of an organism's perception considered as a whole, the "seat of sensation" where it experiences, perceives and interprets the environments within which it lives. The term originally entered English from the Late Latin in the mid-17th century, from the stem sens- ("sense"). In earlier use it referred, in a broader sense, to the brain as the mind's organ. In medical, psychological, and physiological discourse it has come to refer to the total character of the unique and changing sensory environments perceived by individuals. These include the sensation, perception, and interpretation of information about the world around us by using faculties of the mind such as senses, phenomenal and psychological perception, cognition, and intelligence.
The Gutenberg Galaxy: The Making of Typographic Man is a 1962 book by Marshall McLuhan, in which he analyzes the effects of mass media, especially the printing press, on European culture and human consciousness. It popularized the term global village, which refers to the idea that mass communication allows a village-like mindset to apply to the entire world; and Gutenberg Galaxy, which we may regard today to refer to the accumulated body of recorded works of human art and knowledge, especially books.
Visual literacy is the ability to interpret, negotiate, and make meaning from information presented in the form of an image, extending the meaning of literacy, which commonly signifies interpretation of a written or printed text. Visual literacy is based on the idea that pictures can be "read" and that meaning can be discovered through a process of reading.
The Medium Is the Massage: An Inventory of Effects is a book co-created by media analyst Marshall McLuhan and graphic designer Quentin Fiore, with coordination by Jerome Agel. It was published by Bantam Books in 1967 and became a bestseller with a cult following. The U.K. edition was published by Allen Lane Penguin Books using cover art by Newsweek photographer Tony Rollo.
In semiotics, a modality is a particular way in which information is to be encoded for presentation to humans, i.e. to the type of sign and to the status of reality ascribed to or claimed by a sign, text, or genre. It is more closely associated with the semiotics of Charles Peirce (1839–1914) than Ferdinand de Saussure (1857–1913) because meaning is conceived as an effect of a set of signs. In the Peircean model, a reference is made to an object when the sign is interpreted recursively by another sign, a conception of meaning that does in fact imply a classification of sign types.
"The medium is the message" is a phrase coined by the Canadian communication theorist Marshall McLuhan and the name of the first chapter in his Understanding Media: The Extensions of Man, published in 1964. McLuhan proposes that a communication medium itself, not the messages it carries, should be the primary focus of study. He showed that artifacts such as media affect any society by their characteristics, or content.
Medium theory is a mode of analysis that examines the ways in which particular communication media and modalities impact the specific content (messages) they are meant to convey. It Medium theory refers to a set of approaches that can be used to convey the difference in meanings of messages depending on the channel through which they are transmitted. Medium theorists argue that media are not simply channels for transmitting information between environments, but are themselves distinct social-psychological settings or environments that encourage certain types of interaction and discourage others.
Transmedia storytelling is the technique of telling a single story or story experience across multiple platforms and formats using current digital technologies.
Presence is a theoretical concept describing the extent to which media represent the world. Presence is further described by Matthew Lombard and Theresa Ditton as “an illusion that a mediated experience is not mediated." Today, it often considers the effect that people experience when they interact with a computer-mediated or computer-generated environment. The conceptualization of presence borrows from multiple fields including communication, computer science, psychology, science, engineering, philosophy, and the arts. The concept of presence accounts for a variety of computer applications and Web-based entertainment today that are developed on the fundamentals of the phenomenon, in order to give people the sense of, as Sheridan called it, “being there."
Mediation in Marxist theory refers to the reconciliation of two opposing forces within a given society by a mediating object. Put another way "Existence differs from Being by its mediation"...."The Thing-in-itself and its mediated Being are both contained in Existence, and each is an Existence; the Thing-in-it-self exists and is the essential Existence of the Thing, while mediated Being is its unessential Existence ..."
Joshua Meyrowitz is a professor of communication at the department of Communication at the University of New Hampshire in Durham. He has published works regarding the effects of mass media, including No Sense of Place: The Impact of Electronic Media on Social Behavior, an analysis of the effects various media technologies have caused, particularly television.
Commonly called new media theory or media-centered theory of composition, stems from the rise of computers as word processing tools. Media theorists now also examine the rhetorical strengths and weakness of different media, and the implications these have for literacy, author, and reader.
Multiliteracy is an approach to literacy theory and pedagogy coined in the mid-1990s by the New London Group. The approach is characterized by two key aspects of literacy - linguistic diversity and multimodal forms of linguistic expressions and representation. It was coined in response to two major changes in the globalized environment. One such change was the growing linguistic and cultural diversity due to increased transnational migration. The second major change was the proliferation of new mediums of communication due to advancement in communication technologies e.g the internet, multimedia, and digital media. As a scholarly approach, multiliteracy focuses on the new "literacy" that is developing in response to the changes in the way people communicate globally due to technological shifts and the interplay between different cultures and languages.
Multimodality is the application of multiple literacies within one medium. Multiple literacies or "modes" contribute to an audience's understanding of a composition. Everything from the placement of images to the organization of the content to the method of delivery creates meaning. This is the result of a shift from isolated text being relied on as the primary source of communication, to the image being utilized more frequently in the digital age. Multimodality describes communication practices in terms of the textual, aural, linguistic, spatial, and visual resources used to compose messages.
Multimodal pedagogy is an approach to the teaching of writing that implements different modes of communication. Multimodality refers to the use of visual, aural, linguistic, spatial, and gestural modes in differing pieces of media, each necessary to properly convey the information it presents.
