________ theory is a result of research conducted for the AT & T telecommunications company, aimed to account for how a unit of information which is produced by a sender at one end of a communication channel is able to be faithfully reproduced at the other end by a receiver.

The correct answer is - Shannon and Weaver theory

Key Points

• Shannon and Weaver theory
  • This theory was developed by Claude Shannon and Warren Weaver during their research at Bell Laboratories, which was part of AT&T.
  • It focuses on how a unit of information created by a sender can be faithfully reproduced by a receiver through a communication channel.
  • The model identifies key components: sender, encoder, channel, decoder, and receiver.
  • It aims to minimize errors and noise during the transmission process to ensure accurate communication.

Additional Information

• Critical theory
  • Developed by the Frankfurt School, it focuses on critiquing society and culture to reveal and challenge power structures.
  • It is more concerned with societal issues and ideology than communication processes.
• Gerbner enrichment theory
  • This theory is associated with media effects and how media exposure shapes perceptions and beliefs.
  • It is not directly related to the technical communication process between sender and receiver.
• Walter Lippmann theory
  • Lippmann's work, particularly in "Public Opinion," deals with how media shapes public perceptions and the role of stereotypes.
  • It does not specifically address the technical aspects of communication transmission like the Shannon and Weaver model.
