Last week the class went on trip to the Powerhouse Museum in Sydney to view a number of exhibitions. Although very visually pleasing and fun to look at, the objects in the exhibitons also have a particular meaning and function. The objects can be given connonative, denotative and normative meaning.
Congnitive Dissonance theory suggests that people seek consistency among their cognitions. When something happens to create an inconsistency betwen attitudes or behaviours (dissonance), something else must happen to free them of the dissonace. Dissonace often occours when a person must choose between two incompatible beliefs or actions. The strongest dissonance is created when two alternatives are equally attractive. Sometimes advertising can be the source of cognitive dissonace.
