Knowledge that Transforms

A model is proposed which expresses consumer satisfaction as a function of expectation and expectancy disconfirmation. Satisfaction, in turn, is believed to influence attitude change and purchase intention. Results from a two-stage field study support the scheme for consumers and nonconsumers of a flu inoculation.

The relationships between 24 print ad characteristics and recall, readership, and inquiry-generation measures of effectiveness are examined for 1160 industrial ads. Both recall and readership are strongly related to format and content characteristics of industrial ads. The relationship between inquiry-generation and ad characteristics is significant but weaker. Some characteristics, such as ad size and position in the magazine, are consistently related to effectiveness across product categories and effectiveness measures. The effects of other characteristics, such as the use of four colors and attention-getting techniques, are specific to the product category and effectiveness measure. In addition to these substantive findings, methodological issues in model development and testing are presented.

Two segmented methods of performing conjoint anal/sis, clustered and componential segmentation, are compared with each other as well as with individual level and totally aggregate level analyses. The two segmented methods provide insights to the data that (1) are not obtainable at the aggregate level and (2) are in a form that is more easily communicated than the information from the individual level analysis. The predictive power of the clustered segmentation method is higher than that of componential segmentation, and both are superior to the aggregate analysis but inferior to individual level analysis.

Repetition of a pattern of television commercials caused wearout in viewers’ evaluation of the commercials and the products being advertised. As predicted by an information processing view, wearout was not forestalled by strategies designed to enhance attention.
