A classic phenomenon known as prototype preference effect (PPE) or beauty-in-averageness effect is that prototypical exemplars of a neutral category are preferred over atypical exemplars. This PPE has been explained in terms of deviance avoidance, hedonic fluency, or preference for certainty and familiarity. However, typicality also facilitates greater activation of category-related information. Thus, prototypes rather than atypical exemplars should be more associated with the valence of the category, either positive or negative. Hence, we hypothesize that the evaluation of a prototype depends on the valence of its category. Results from three experiments crossing a standard PPE paradigm with an evaluative conditioning procedure support our hypothesis. We show that for positive categories, greater typicality increases liking. Critically, for negative categories, greater typicality decreases liking. This pattern of results challenges dominant explanations of prototype evaluation.

The articulatory in-out effect describes the preference for stimuli with an inward-wandering consonant order (e.g., BODIKA) as opposed to an outward-wandering consonant order (e.g., KODIBA). Originally, the in-out effect has been explained in terms of articulation trajectories, with inward trajectories being preferred over outward trajectories. However, recent research by Maschmann et al. ( 2020) raised doubts on this explanation of articulation trajectory preferences and offered a parsimonious alternative explanation for the in-out effect based on consonant preferences instead. As we show in the present article, stimulus materials in Maschmann et al. ( 2020) diverged from materials used in previous research and might have prevented the experience of articulation trajectories. Here, we present a conceptual replication of Maschmann et al. ( 2020), using stimulus materials more likely to elicit articulation trajectory preferences. In a preregistered, high-powered experiment (N = 349), we find strong support for the original idea of trajectory preferences but no evidence for the consonant preference account. Our research shows that preferences for articulation trajectories are robust and cannot be explained by mere consonant preferences. We discuss further implications of these findings for future research on the processes involved in the empirical in-out effect.

In the last decade, there has been a growing research focus on the subtle modifications of choice architecture that have strong effects on consumer behavior and are subsumed under the term nudging. There is still little research, however, on how different nudges influence individuals with different personality characteristics. An experimental online shopping scenario is used to test whether a customer's Need for Cognition and Need for Uniqueness moderate the effectiveness of two of the most prominent nudges—defaults and social influence. Two experiments with samples stratified by age, gender, and education (total N = 1,561) reveal that defaults and social influence have the predicted impact on a customer's decision. Across both studies, nudge effectiveness was partially impacted by Need for Cognition and not impacted at all by Need for Uniqueness. These findings imply that both types of nudges are strong and robust techniques to influence consumer decision‐making and are effective across different levels of consumer's Need for Cognition or Need for Uniqueness.
