Colour words shape adults’ categorical perception \citep{Roberson:2007wg,Winawer:2007im}.

There is evidence that the infant mode of categorical perception of colour continues to operate in adults, although it is often inhibited or overshadowed by the adult mode \citep{Gilbert:2006yb}.

‘Several studies found that category effects occur only or more strongly in the right visual field but not at all or less strongly in the left visual field (Drivonikou et al. 2007, Gilbert et al. 2006, Roberson et al. 2008, Zhou et al. 2010). Visual information from the right visual field is processed in the left hemisphere and language is also processed in the left hemisphere for almost all people who are right-handed (for a review, see Ocklenburg et al. 2014). The observation that the category effect is lateralized to the left hemisphere suggested that language processing is involved in those category effects. Although several studies found evidence in support of the lateralized category effect, many other studies could not reproduce the effect, even in extensive series of experiments and with carefully calibrated color stimuli (Brown et al. 2011; Suegami et al. 2014; Webster \& Kay 2012; Witzel \& Gegenfurtner 2011, 2015, 2016). It has been suggested that the lateralization of the category effect occurs only at early stages and disappears at later stages of visual processing, possibly due to transfer through the corpus callosum (Roberson et al. 2008, Constable \& Becker 2017)’ \citep[pp.~487--8]{witzel:2018_colora}.
