Barnlund's transactional model of communication was proposed in 1970 and presents a multi-layered feedback system where anyone can be a sender and receiver. It includes both verbal and non-verbal layers of feedback and is considered the most systematic of the functional models. The model accounts for public cues, private cues, behavioral cues, filters, noise and feedback in the communication process between sender and receiver.

2.  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

4.  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.

5.  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.

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

8.  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.

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