Five experiments demonstrate that exposure to novel visual stimulus arrays of geometric shapes affects consumers' real choices among products. The authors first demonstrate that exposure to variety arrays (arrays of differing shapes) increases variety seeking (Study 1). They then show that exposure to uniqueness arrays (e.g., one circle among six squares) increases choice of unique over common objects (Studies 2 and 3) and interacts with chronic need for uniqueness (Study 3). In the final two studies, the authors show that variety and uniqueness arrays activate distinct constructs; specifically, they find no effect of exposure to uniqueness arrays on variety seeking (Study 4a) and no effect of exposure to variety arrays on uniqueness seeking (Study 4b). Taken together, these studies build on the existing literature about nonconscious effects on consumer behavior and choice behavior in particular by showing that consumers' real choices are affected by subtle exposure to novel stimuli that do not have any previous associations.

Studies of consumer decision making often begin with the identification of a dimension on which options differ, followed by an analysis of the factors that influence preferences along that dimension. Building on a conceptual analysis of a diverse set of problems, the authors identify a class of related consumers choices (e.g., extreme vs. compromise, hedonic vs. utilitarian, risky vs. safe) that can all be classified according to their levels of self- versus other-expression (or [un]conventionality). As shown in four studies, these problem types respond similarly to manipulations that trigger or suppress self-expression. Specifically, priming self-expression systematically increases the share of the self-expressive options across choice problems. Conversely, expecting to be evaluated decreases the share of the self-expressive options across the various choice dilemmas. In addition, priming risk seeking increases only the choice of risky gambles but not of other self-expressive options. These findings highlight the importance of seeking underlying shared features across different consumer choice problems, instead of treating each type in isolation.

People often infer expertise from the choice of unique, rare, or sophisticated options. But might mere variety‐seeking also serve as a signal of expertise, and if so, how? Six studies show that the relationship between variety‐seeking and perceived expertise is not unidirectional and depends on the perceiver's own level of expertise. Category experts perceive lower variety‐seeking as indicative of discernment, which in turn increases perceived expertise in that category. Consequently, experts choose less variety to portray themselves as experts. In contrast, novices perceive high variety‐seeking as indicative of category breadth knowledge, which in turn increases their perception of category expertise. Consequently, novices choose more variety to portray themselves as experts. The findings make novel theoretical contributions to research on variety‐seeking, consumer expertise, and social perception, as well as practical contributions for marketers of product assortments and bundles.

In this paper, we present a framework for understanding long-lasting influences on children's foodpurchase choices and consumption. The framework interacts the characteristics of agents (i.e., children and parents/caretakers) with marketing-related effects to explain how these agents make short-and long-term decisions in the food category. We develop each of the components of our framework with different theories and multiple empirical examples, focusing on how children develop their food preferences and how their understanding of and resistance to persuasion and marketing messages may influence choices. Overall, the presented approach suggests firms, consumers, and parents can benefit from taking these factors into account when making choices that affect children and when allowing children to make their own choices.
