2. Today’s Lecture
•Communication modeling
•Simple transactional communication model
•Interference transactional communication
model

3. What is communication modeling?
•It explains the way people
exchange information.
•Think of it as a way to
describe or illustrate
communication more
broadly…allowing you to
determine the best
approach for each situation.

8. Interference Transactional Model
Continued
•Builds upon the simple transaction model by adding the
concept of interference, both internal and external.
External interference is the surrounding noise and distraction that
serves as obstacles to communication (e.g., a crying baby).
Internal interference may be subjective, a person’s inability to
concentrate because of mental fatigue, or the inability to remain
objective towards the topic.
•Interference can impede the encoding, the transmission,
the decoding, and/or the feedback, thereby greatly
reducing the effectiveness of communication.
