About the PhD thesis

With the growth of online shopping, a new era of market communication is administered. Internet as a combined communication- and sales-channel has blurred the borders between persuasive communications to activate goals (i.e., abstract messages that are traditionally communicated via advertisements, commercials and billboards) and concrete recommendations to activate choices (i.e., concrete messages that are traditionally communicated by promotions on the shop floor). The blurring borders between abstract persuasive communications and concrete recommendations call for new research to gain insight in the interplay between abstract and concrete product messages.

In the first essay, the differential impact of abstract benefit messages and concrete product examples on goal activation and choice behaviour are investigated. In the second essay the cognitive structure in consumers’ minds that underlies the behaviour observed in essay 1 is further unravelled. In essay 3 the applicability of the findings is broadened by investigating the impact of abstract benefit messages versus concrete product messages on consumer behaviour outside the focal product category mentioned in the messages. The findings are based on consumer data gathered in lab-experiments and from a panel survey. All of the essays discuss applications to health related products.

In summary, this dissertation shows some interesting theoretical findings about the relative impact of abstract versus concrete product messages. It is also of particular interest to commercial companies and public policy makers, because it provides suggestions on how to steer consumer decision-making processes with product messages to promote healthier consumer choices.
