Despite evidence that currency denomination can influence spending, researchers have yet to examine whether the physical appearance of money can do the same. This is important because smaller denomination bills tend to suffer greater wear than larger denomination bills. Using real money in the context of real purchases, this article demonstrates that the physical appearance of money can override the influence of denomination. The reason being, people want to rid themselves of worn bills because they are disgusted by the contamination from others, whereas people put a premium on crisp currency because they take pride in owning bills that can be spent around others. This suggests that the physical appearance of money matters more than traditionally thought, and like most things in life, it too is inextricably linked to the social context. The results suggest that money may be less fungible than people think.

New products are often incongruent with consumer expectations. Researchers have shown that consumers prefer moderately incongruent products, while being adverse to extremely incongruent products. Evidence from three studies suggests that this phenomenon is highly influenced by a consumer's state of arousal. Specifically, low arousal decreases preference for moderate incongruity while increasing preference for extreme incongruity, whereas high arousal decreases preference for any form of incongruity. Underlying these effects are discrete emotional states brought on by a physiological response to incongruity. Varying arousal subsequently varies the severity of the emotion, be it negative (anxiety) or positive (curiosity), which in turn varies evaluations for the product. This suggests that creating excitement around a product launch may be good for incremental innovation, but it may not be a good idea for something truly innovative.

Evidence from three experiments shows that due to superior visuo-spatial elaboration, females (relative to males) have a heightened ability to identify visually incongruent products that are promoted among competing products. Females discriminate relational information among competing advertisements and use this information to identify incongruent products that would otherwise go unidentified. Consequently, they evaluate the products more favorably. Consistent with predictions of a limited capacity in working memory, we find this performance for females coincides with a reduction in ad claim recognition. Close inspection reveals the trade-off between product identification and ad recognition is the result of involuntary resource allocation from verbal processing to visuo-spatial processing. Hence, females may be able to use the advertising context to identify an extremely incongruent product, but this performance is not without a cost. Our results have important implications for research on product incongruity, gender, and advertising context.
