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. (PsycInfo Database Record (c) 2022 APA, all rights reserved).
