SPCH COMM HCC Northwest Fall 2011
Today’s Objective
Continue to explore the communication
modeling process
Connect our knowledge of roles and
actions in the linear model to the
transactional model
Recognize and apply concepts of the
transactional model to our own
communication episodes
Pages 7-12 of your textbook. Model is Fig 2., page 9
Recall what we learned about the linear
model of communication
 Shannon and Weaver; 1949; scholarly dialogue in
business, communication, education, psychology
& sociology.
Critique of S&W’s linear model
Process explained
Highlights information transfer
Identification of roles, roles are rigid
Opens up process for questions about people
21 years later a more dynamic model emerged
Dean C. Barnlund submitted this model in 1970
Barnlund’s Transactional Model
of Communication
The language of communication
Two-way, continuous transaction
In a transactional model . . .
We activate a dynamic, simultaneous
Participants are ‘sending’ and ‘receiving’
at all times
Encoding and decoding can and will
happen unconsciously
 Communicators
give and get simultaneously
 Communicators
come into the episode with
personal experiences, personalities and traits,
cultural backgrounds and relational histories
 The
background details, along with the
physical location, comprise the environment
of the episode
Three types of noise impact communication in
the transactional model
External Noise: Auditory interference
Physiological Noise: Biological interference
Psychological Noise: Internal noise , thought
In 1970 Barnlund put forth the Transactional
Model of Communication, a two-way,
communicator and meaning centered model
Some concepts are revised from the linear model,
including simultaneous roles, impact of channels,
types of noise, communicator background and
shared meaning.
