In organizational psychology, communication is defined as the exchange of information, meaning, and understanding between two or more system entities. When this process fails, communication barriers emerge, leading to misunderstandings, reduced morale, and impaired organizational performance.
- Shannon-Weaver Model (1949): Introduced the concept of noise—any disturbance that interferes with the transmission of a signal from source to destination. This includes psychological noise (cognitive biases, emotional states) and semantic noise (jargon, language differences).
- Carl Rogers and Marshall McLuhan: Rogers emphasized that the major barrier to interpersonal communication is our very natural tendency to judge, to evaluate, to approve or disapprove the statements of the other person. McLuhan focused on channel constraints ("the medium is the message").
- Keith Davis (1967): Classified organizational communication flows (downward, upward, lateral) and identified primary filtering mechanisms used by individuals within hierarchies.
