The authors present the results of two studies that show how consumers' evaluations of an advertised product can be influenced by the compatibility or conflict between the regulatory goals (promotion or prevention) addressed by the product and prior advertising of related products. Participants across both studies were exposed sequentially to the advertising of two products (prime and target), and they demonstrated a regulatory goal fluency effect in their evaluations of the target brand. When the regulatory goal serviced by the target matched (conflicted with) the regulatory goal serviced by the prime, participants indicated higher (lower) purchase intent (Experiment 1) and more favorable evaluations of the target brand (Experiment 2). These effects were not accounted for by differences in participants' involvement or affective state across the conditions. Instead, mediation analyses show that participants' ease of processing the target advertisement underlies the effect of goal compatibility on brand evaluation.

According to the processing fluency model, advertising exposures enhance the ease with which consumers recognize and process a brand. In turn, this increased perceptual fluency leads to consumers having more favorable attitudes toward the brand. The authors extend the processing fluency model to examine the effect of conceptual fluency on attitudes. In three experiments, the authors show that when a target comes to mind more readily and becomes conceptually fluent, as when it is presented in a predictive context (e.g., a bottle of beer featured in an advertisement that shows a man entering a bar) or when it is primed by a related construct (e.g., an image of ketchup following an advertisement of mayonnaise), participants develop more favorable attitudes toward the target. It is believed that positive valence of fluent processing underlies these processing-fluency effects. When conceptual fluency is associated with negative valence (e.g., hair conditioner primed by a lice-killing shampoo), the authors observe less favorable attitudes.

More than 200 studies suggest that metacognitive difficulty reduces the liking of an object. In contrast to those findings, the authors demonstrate that the effects of metacognitive experiences on evaluation are sensitive to the consumption domain. In the domain of everyday goods, metacognitive difficulty reduces the attractiveness of a product by making it appear unfamiliar. However, in the context of special-occasion products, for which consumers value exclusivity, metacognitive difficulty increases the attractiveness of a product by making it appear unique or uncommon. The authors reconcile their findings with prior research by positing that the effect of metacognitive experiences on evaluation depends on the naive theory people associate with product consumption. Four studies demonstrate the proposed effect and test for the role of lay theories in the interpretation of metacognitive experiences. The authors conclude with a discussion of theoretical and marketing implications.
