RESUMEN
According to Levelt's language production model, in order to name an object, speakers must first conceptualize and lexicalize the object before its name can be articulated. Conceptualization is conducted through the semantic network that exists at the conceptual level, with the highly activated concept(s) activating lexical items at the lemma-level, i.e., lexicalization. So far, research focused mostly on semantic categories (i.e., semantic interference) but less so on animacy - a concept that is correlated with semantic categories. To investigate the role of this semantic feature in language production, we conducted a picture-word interference study in Mandarin Chinese varying animacy congruency and controlling for classifier congruency while recording behavioral and electrophysiological responses. We observed an animacy interference effect together with a larger N400 component for animacy-incongruent vs. congruent picture-word pairs, suggesting animacy-congruent concepts may be in closer proximity and hence lead to a stronger spreading of activation relative to animacy-incongruent concepts. Furthermore, a larger P600 component was observed for classifier-incongruent vs. congruent picture-word pairs, suggesting syntactically-driven processing of classifiers at the lemma level.
RESUMEN
An essential step to create phonology according to the language production model by Levelt, Roelofs and Meyer is to assemble phonemes into a metrical frame. However, recently, it has been proposed that different languages may rely on different grain sizes of phonological units to construct phonology. For instance, it has been proposed that, instead of phonemes, Mandarin Chinese uses syllables and Japanese uses moras to fill the metrical frame. In this study, we used a masked priming-naming task to investigate how bilinguals assemble their phonology for each language when the two languages differ in grain size. Highly proficient Mandarin Chinese-English bilinguals showed a significant masked onset priming effect in English (L2), and a significant masked syllabic priming effect in Mandarin Chinese (L1). These results suggest that their proximate unit is phonemic in L2 (English), and that bilinguals may use different phonological units depending on the language that is being processed. Additionally, under some conditions, a significant sub-syllabic priming effect was observed even in Mandarin Chinese, which indicates that L2 phonology exerts influences on L1 target processing as a consequence of having a good command of English.

English words with an inconsistent grapheme-to-phoneme conversion or with more than one pronunciation ("homographic heterophones"; e.g., "lead"-/lεd/, /lid/) are read aloud more slowly than matched controls, presumably due to competition processes. In Japanese kanji, the majority of the characters have multiple readings for the same orthographic unit: the native Japanese reading (KUN) and the derived Chinese reading (ON). This leads to the question of whether reading these characters also shows processing costs. Studies examining this issue have provided mixed evidence. The current study addressed the question of whether processing of these kanji characters leads to the simultaneous activation of their KUN and ON reading, This was measured in a direct way in a masked priming paradigm. In addition, we assessed whether the relative frequencies of the KUN and ON pronunciations ("dominance ratio", measured in compound words) affect the amount of priming. The results of two experiments showed that: (a) a single kanji, presented as a masked prime, facilitates the reading of the (katakana transcriptions of) their KUN and ON pronunciations; however, (b) this was most consistently found when the dominance ratio was around 50% (no strong dominance towards either pronunciation) and when the dominance was towards the ON reading (high-ON group). When the dominance was towards the KUN reading (high-KUN group), no significant priming for the ON reading was observed. Implications for models of kanji processing are discussed.
