The most important difference in comparison to the original studies by Ameel et al. (2005, 2008, 2009) is the expanded set of stimuli. Concerning the collection of the naming data for the adults, we opted for an online naming task for practical reasons. In the original study, two different sets of stimuli were used (“bottles” set and “dishes” set). Since we expanded the stimulus set, it was not feasible to replicate the study for both sets of stimuli. As to the sorting task, we made the decision to only collect sorting data from monolingual participants. Given that perceived similarity collected from different language groups shows negligible differences, previous studies support the assumption of a common underlying object representation (Malt et al., 1999; Ameel et al., 2005). People of different languages and cultures share a perception of the similarity among entities within at least some domains (e.g., common household containers: Malt et al., 1999; Ameel et al., 2005; color: Roberson and Davidoff, 2000; human locomotion: Malt et al., 2014; and spatial relations: Munnich et al., 2001). As mentioned above, we also allowed the participants to sort in different levels in order to obtain more detailed information concerning perceived similarity (see earlier). In the original study, participants completed both the naming task and the sorting task. Given the large dataset, and the longer duration of the testing procedure, we opted to gather the sorting data with participants who did not do the naming task.
