Answer:
B) provide controls to avoid the biasing effects of the exposure context.
Step-by-step explanation:
The Positioning Advertising Copy Testing (PACT) are a set of 9 principles used to test the effectiveness of advertisements. They were developed by a group of 21 leading advertising agencies.
- Provides measurements which are relevant to the objectives of the advertising.
- Requires agreement about how the results will be used in advance of each specific test.
- Provides multiple measurements, because single measurements are generally inadequate to assess the performance of an advertisement.
- Based on a model of human response to communications—the reception of a stimulus, the comprehension of the stimulus, and the response to the stimulus.
- Allows for consideration of whether the advertising stimulus should be exposed more than once.
- Recognizes that the more finished a piece of copy is, the more soundly it can be evaluated and requires, as a minimum, that alternative executions be tested in the same degree of finish.
- Provides controls to avoid the biasing effects of the exposure context.: it refers to how the audience recalls the ads depending on whether they were TV, radio or printed ads.
- Takes into account basic considerations of sample definition.
- Demonstrates reliability and validity.
