We used a naming task in which participants were asked to name the color of colored line drawings of objects in Cantonese1. The relationship between color and object was manipulated in such a way that the onset of the color and object was phonologically related or -unrelated (see Figure 1). We expected to see not only ERP differences (i.e., evidence of segment as a functional unit of phonological processing), but also behavioral facilitation (i.e., evidence of segment being the proximate unit of processing) as has been found in Dutch. Furthermore, we were interested in how ERP evidence on initial segment priming may differ from or confirm findings in Qu et al. (2012) and Yu et al. (2014).
