Resolving Sequential Self-Control Dilemmas: The Role of Pride and Guilt
Extant evidence suggests that the two self-conscious emotions pride and guilt guide people's behavior in the context of self-control dilemmas. Pride and guilt are both outcomes of and antecedents to how people resolve self-control dilemmas. However, evidence on how pride and guilt motivate individuals to exert self-control is inconsistent. Based on the Expectancy Value Theory, we propose a conceptual framework to predict when and how pride and gu…
In Visceral Control: When Visceral States Facilitate Versus Inhibit Priming Effects
Despite the abundance of priming effects identified in the literature, the replicability of prior findings pertaining to several priming effects has been recently challenged. Therefore, research has focused more extensively on pinpointing boundary conditions under which priming effects might surface or be attenuated. We contribute to this stream of literature, showing how visceral states (“hot” affective states) moderate the effectiveness of prim…
With a little help from my retailer: Shopper acceptance of nutritional decision aids supporting healthy grocery shopping
Front-of-package (FOP) nutrition labels are increasingly implemented as an intervention for promoting healthier purchases. However, the impact of FOP labels on actual purchase decisions appears to remain rather limited. As healthy grocery shopping is an effortful and difficult task, shoppers may benefit from additional support. Therefore, this study examines shopper acceptance of seven nutritional decision aids (NDAs), tools that support shoppers…
Can graphic warning labels reduce the consumption of meat
The classification of red meat as "probably carcinogenic" and processed meat as "carcinogenic" was followed by pleas to place warning labels, akin to those used for tobacco products, onto meat products. These labels educate people about the health risks associated with the target behavior and are typically accompanied by graphic imagery that elicits disgust (e.g., a picture of blackened lungs). Although the emotion of disgust has been shown to be…
Losses tune differently than gains: How gains and losses shape attentional scope and influence goal pursuit
Research on the asymmetric effect of negative versus positive affective states (induced by gains or losses) on scope of attention, both at a perceptual and a conceptual level, is abundant. However, little is known about the moderating effect of anticipating gains or losses versus actually experiencing them and about any downstream consequences of these effects on goal-directed behaviour. In two studies, we show that gains versus losses induce qua…
A packaged mindset: How elongated packages induce healthy mindsets
Propelling pride to promote healthy food choices among entity and incremental theorists
Past research suggests that people's beliefs about the malleability of their body weight influence their motivation to engage in healthful behaviors: people who perceive their body weight as fixed (entity theorists) engage less in healthful behaviors than people who perceive their body weight as changeable (incremental theorists). Accordingly, current health interventions frequently aim at shifting entity theorists' beliefs about the malleability…
In-Store Spending Dynamics: How Budgets Invert Relative-Spending Patterns
The authors conduct four controlled lab experiments and one field study in a brick-and-mortar grocery store to demonstrate that relative spending-the price of the purchased item relative to the mean price of the product category-evolves nonlinearly and distinctly for budget and nonbudget shoppers. While the relative spending of budget shoppers evolves in a concave manner, the relative spending of nonbudget shoppers evolves inversely in a convex m…
Fast Food Restaurant Lighting and Music can Reduce Calorie Intake and Increase Satisfaction
Recent research shows that environmental cues such as lighting and music strongly bias the eating behavior of diners in laboratory situations. This study examines whether changing the atmosphere of a fast food restaurant would change how much patrons ate. The results indicated that softening the lighting and music led people to eat less, to rate the food as more enjoyable, and to spend just as much. In contrast to hypothesized U-shaped curves (pe…
Plate Size and Color Suggestibility: The Delboeuf Illusion's Bias on Serving and Eating Behavior
Despite the challenged contention that consumers serve more onto larger dinnerware, it remains unclear what would cause this and who might be most at risk. The results of five studies suggest that the neglected Delboeuf illusion may explain how the size of dinnerware creates two opposing biases that lead people to overserve on larger plates and bowls and underserve on smaller ones. A countercyclical sinus-shaped relationship is shown to exist bet…

Bottoms Up! The Influence of Elongation on Pouring and Consumption Volume
Although the effects of shapes on area perceptions have been widely investigated, we replicate, extend, and generalize one of the few studies to relate the effects of shapes to consumption volumes (Raghubir and Krishna 1999). While Raghubir and Krishna demonstrate the effect of the elongation of prepoured drinks on consumption volume, we have people pour their own drinks in a series of controlled field experiments. Two experiments in cafeterias s…
