Source refers to a person or group of persons with a purpose for engaging in communication
Receiver refers to the person or group of persons at the other end of the communication process
Message is what the source must have to transmit
Channel is the mode of encoding and decoding messages
Effect is the outcome of communication or the response of the receiver to the message
Feedback is the communication response to both source and receiver
Levels of Communication:
Intrapersonal Communication: Communication with oneself
Interpersonal Communication: Face-to-face communication, person-to-person communication
Mass Communication: Communication that employs technological devices to disseminate symbolic content to large, heterogeneous, and widely dispersed audiences
Laswell's Model by Harold D. Laswell:
S (who), R (to whom), M (says what), E (with what effect), C (in which channel)
Shannon and Weaver's "Mathematical" Model by Claude Shannon and Warren Weaver:
Information, transmitter, receiver, destination, one-way linear model
Newcomb’sModel:
Introduces the role of communication in a society or social relationship
Communication maintains equilibrium within a social system
If A and B have similar attitudes about X, then the system is in equilibrium. Should their attitudes differ, then there is no equilibrium and A and B must communicate to find a way to put their system in balance
Osgood and Schramms Model by Wilbur Schramm and Charles Osgood:
Compares their model to Shannon and Weaver’s (focus on channel)
Focuses on the actors in the communication to be equal in performing the tasks of encoding, interpreting, and decoding messages
Cyclical representation (Schramm, 1954) states that the communication process is endless
Dance’s Helical Model:
Portrays the communication process as moving
Shows the dynamism of the communication process
May be used to illustrate information gaps and the thesis that knowledge tends to create more knowledge
Kincaid’sConvergence Model by D. Lawrence Kincaid:
Shows a process of convergence to which participants share information so that mutual understanding is reached
Once mutual understanding is reached, there is mutual agreement, then collective action can be taken
Distortions in effective communication:
Distortions in the message
Misinformation
Lackofinformation
Berlo's explanation of communication effectiveness:
Effect is the difference between what a receiver thinks, feels, and does before and after exposure to a message
Effect is best expressed in behavioralterms
The communicator has one or more purposes: to gain attention, understanding, or acceptance, or to elicit action
Noise in communication:
Anyinterference with the message travelling along the channel
Examples include static over telephone lines, blaring of the radio, car horns outside your window
Classifying Communication Barriers:
Technical Problems Barriers: How accurately the message can be transmitted
Semantic Problems: How precisely the meaning is conveyed
Effectiveness Problems: How effectively does the received message affect behavior
Barriers of communication classified by a group of scientists into five categories:
1. Physical barriers
2. Psychological-cultural barriers
3. Socialbarriers
4. Channel Noise
5. Environmental Factors
6. Semantic Noise
7. Socio-Psychological Barriers
Communication Competence according to Rothwell (1992):
Knowing what constitutes human communication does not automatically make you an effective communicator
Qualities of a Competent Communicator:
They have a We-not-Me Orientation
They understand communication effectiveness
They have a sense of appropriateness
4 Basic Components Of Communication Competence by Littlejohn and Jabusch (1982):
1. Understanding
2. Communication skills
3. Interpersonal sensitivity
4. Ethical responsibility
Shockley-Zalabak (1988) modified the components into four easily remembered elements:
