Transcript The Process and Effects of Mass Communications

Communication theory
Communication: a two-way process
that involves the exchange of
messages between two or more
parties.
Key to successful communication
• relationship that exists between the sender
and receiver of message
• type of message and timing of its
transmission
• environment in which the message is
transmitted and received
• ability of both parties to understand each
other and relate to each other

Decoding
• receiver interprets words, signs, symbols,
colours, sounds
• high incidence of misunderstandings
• receiver selectivity in interpretations
• e.g. public health communications – ‘it
couldn’t happen to me’
• effective communication – if the receiver
gives message the same meaning that the
sender gave it.
Noise
• busy environments
• noise from the sender – conflicting messages can
often be sent
• quality of media
• competitor activity
Feedback
• Helps measure effectiveness of communication
• research
Measuring communications
effectiveness
• research to assess target audience’s
awareness and understanding of message
• identification of noise sources
• sales
• direct response rates
• uptake of sales promotions
Interpreting communications
• codes
– a common set of rules or interpretative devices known
to the sender and receiver of messages
– assign a specific meaning or content to a sign
– improve consumers’ efficiency
– add to the enjoyment of consumers’ activities
• semiotics
– the study and interpretation of various signs used in
communication
