The effects of memory set accessibility and relevance on the use of memory information during product choice

The Accessibility-Relevance framework provides a useful perspective to consider the retrieval and use of memory information during product decision making (Alba, Lynch, and Hutchinson, 1990; Lynch, Marmorstein, and Weigold, 1989). However, it considers accessibility on an individual brand basis, while actual product choice often includes information across multiple alternatives. Thus, memory set accessibility (MSA), the relative accessibility across memory brands, is introduced as a potentially important but unexplored issue within the Accessibility-Relevance research stream. This study 1) provides an explanation for how MSA may produce results which significantly expand the current Accessibility-Relevance conceptualization and 2) considers the effects of MSA and relevance on both brand processing and choice.
