1.
 Proposed by Dean Barnlund in 1970
 Presents a multi-layered feedback system
for all parties involved, and recognizes that
anyone can be a sender and receiver at the
same time.
 Layers of feedback consists of both verbal
and non-verbal cues.
 Most systematic of the functional models

2.
 Cues refer to the signs for doing something.
› Public Cues (CPU) – are physical,
environmental, or artificial and natural or man-
made.
› Private Cues (CPR) – are also known as private
objects of orientation which includes senses of a
person.
› Behavioral Cues – can be verbal as well as
non-verbal.

3.
 Jagged lines show that the availability of
cues can be unlimited and are denoted as
VVVV.
 The valence signs, +, 0, and – are also
attached to these types of cues.
 Speech act refers to particular instance of
communication in the model.

4.
 Filters are the realities of people engaged in
communication.
 Noise is the problem that arises in
communication flow and disturbs the
message flow.

5.
 The model shows shared field experience of
the sender and receiver.
 Talks about simultaneous message sending
noise and feedback.
 Is taken by critics as the most systemaic
model of communication.

6.
 Very complex
 Both the sender and receiver must
understand the codes sent by the other .
