A two-sample t-test demonstrated that the average distance in category centers between bilinguals is significantly smaller than the average distance between roughly corresponding centers for monolinguals. This is the case for the boundary dependent measure [t(29) = 8.90, p < 0.0001] and for the boundary independent measure [t(29) = 6.01, p < 0.0001]. Convergence takes place at both category boundaries and category centers confirming the findings of Ameel et al. (2009).
