To answer the question whether the bilingual categories consistently lie in between the monolingual categories, the ratio of the indirect distance to the direct distance for each monolingual category pair was calculated. The indirect distance consists of the summed distance from the monolingual Dutch to the bilingual Dutch center, from bilingual Dutch to bilingual French and bilingual French to monolingual French. If the bilingual categories are indeed situated in between the monolingual category centers, then the ratio of the indirect distance to the direct distance should be approximately one. Ameel et al. (2009) reported that this was the case indeed. Figure 7 displays the ratios of the indirect distance to the direct distance of the replication study. However, unlike the original study, this is only consistently the case for the category pair tube-tube regardless of the dimension or whether the centers were calculated in a boundary dependent or boundary independent way.
