Scent research has focused primarily on the effects of ambient scent on consumer evaluations. We focus instead on the effects of product scent on consumer memories. For instance, if a pencil or a facial tissue is imbued with scent (vs. not), recall for the brand's other attributes increases significantly-with the effects lasting as much as 2 weeks after exposure. We also find that product scent is more effective than ambient scent at enhancing memory for product information. We suggest that this may be because, with product (ambient) scent, scent-related associations are focused on a single object (are diffused across multiple objects) in the environment. In support, we find that the memory effects are driven by the number of product/scent-related associations stored in long-term memory. The results suggest that, although ambient scent has received the bulk of attention from researchers and managers in recent years, greater focus on product scent is warranted.T he actions of firms in recent years suggest that imbuing products with scents can enhance brand equity. Firms have sought scent-based trademarks for products such as sewing thread (Brookman 1999), automobile tires (Carter 1995), and tennis balls (Bird 2000). Are such trademark protection efforts worthwhile? We attempt to answer this question by exploring the effect of product scent on consumers' ability to remember product information over time.To date, consumer research on scent has focused primarily on the effects of scent on product evaluation (Bone and Ellen 1999;Bone and Jantrania 1992;Bosmans 2006;Laird 1932;Mitchell, Kahn, and Knasko 1995;Spangenberg, Crowley, and Henderson 1996) as well as lingering time (Spangenberg et al. 1996) (Mitchell et al. 1995). Some initial work has examined the effects of scent on memory (Morrin andRatneshwar 2000, 2003), but these efforts have focused exclusively on the effects of ambient scent rather than product scent. Yet the use of product scent would appear to be much more widespread in the marketplace. Moreover, product scent may be particularly effective at enhancing memory for product information as a function of its ability to enhance a product's distinctiveness within its surrounding context. Specifically, we show that, when products are scented (vs. not), consumers are more likely to remember information about those products. This occurs even though the product scent is not reintroduced at the time of recall and even when memory is assessed as much as 2 weeks after product exposure. In exploring the process at work for this effect, we show that the number of scent-related thoughts available at the time of information retrieval mediates the effect of the product scent on memory for product information. Additionally, ambient scent is not found to exhibit a similar effect on memory for an individual product, and we argue that this is due to a product scent's ability to make a product perceptually distinctive within its environment. We rule out alternative explanations for a product scent's effect on memory, name...
