What are the changes in the achievements of classical communication in network communication?

Carl Hovland (192l-1961) was a professor of experimental psychology at Yale University and one of the founders of communication. In 1953, Communication and Persuasion was published.

5. Talk about the three periods of communication effect research and the changes in the effect concept.

A: From the bullet theory in the early 20th century, to the theory of limited effects in the 40s and 60s, and then to the macro effects after the 70s, people's understanding of the effects and influence of mass communication has undergone a process of continuous deepening. On the surface, the early bullet theory and the macro-effect theory after the 70s both emphasized the benefits of mass communication effects and influences, but there are fundamental differences between the two.

In other words, the former advocates an unconditional, unmediated absolute effect, while the latter is a re-evaluation of the impact and effect of mass communication on the basis of full consideration of various constraints.

Communication is a science that studies the occurrence and development of all human communication behaviors and communication processes, as well as the relationship between communication and people and society, and is a science that studies social information systems and their operation laws. In short, communication is the study of how human beings use symbols to communicate social information. Communication is also known as communication, communication, etc.

There must be a correct form of communication to avoid adverse effects

With the continuous improvement of human cognitive ability, all kinds of sciences continue to extend and interconnect, and a large number of new theories and new theories emerge, which paves the way for the emergence of communication studies.

The research object of communication is very broad, broadly speaking, it includes all the communication phenomena and communication activities of human society, and in a narrow sense, it can be divided into two major schools, one is the traditional school centered on the United States, including Canada, Australia and other Pacific Rim countries, and the other is the Western Europe-centered critical school opposed to the United StatesHowever, the connection between things is always multi-faceted and multi-angled, which requires no one research method and correspondingly several different characteristics to meet the in-depth study and investigation of a certain aspect of things.

No matter what kind of communication science is, it is inseparable from the two subjects of the receiver and the recipient. The ultimate purpose of the communicator is to meet the information needs of the recipient, and the receiver as the receiver of the message is more eager to receive the information that he is interested in from the receiver, which requires the establishment of an interactive relationship between the transmitter and the receiver, that is, the receiver surveys the audience, and the audience gives the communicator information feedback

Although the direct and obvious purpose of communication is to achieve the best communication effect, the production of the effect will naturally have an impact on society, and the development of society will also bring changes to all aspects of communication science. The progress of science and technology is increasingly enriching the media of communication, improving the speed of communication, expanding the scope of communication, making communication science better serve the society and the people, so that fresh information can be transmitted to every inch of space at the fastest speed, and let the dawn of communication illuminate the whole earth.

Satisfy the in-depth study and investigation of a certain aspect of things.
