Previous ERP studies have often reported two ERP components—LAN and P600—in response to subject-verb (S-V) agreement violations (e.g., the boys *runs). However, the latency, amplitude and scalp distribution of these components have been shown to vary depending on various experiment-related factors. One factor that has not received attention is the extent to which the relative perceptual salience related to either the utterance position (verbal inflection in utterance-medial vs. utterance-final contexts) or the type of agreement violation (errors of omission vs. errors of commission) may influence the auditory processing of S-V agreement. The lack of reports on these effects in ERP studies may be due to the fact that most studies have used the visual modality, which does not reveal acoustic information. To address this gap, we used ERPs to measure the brain activity of Australian English-speaking adults while they listened to sentences in which the S-V agreement differed by type of agreement violation and utterance position. We observed early negative and positive clusters (AN/P600 effects) for the overall grammaticality effect. Further analysis revealed that the mean amplitude and distribution of the P600 effect was only significant in contexts where the S-V agreement violation occurred utterance-finally, regardless of type of agreement violation. The mean amplitude and distribution of the negativity did not differ significantly across types of agreement violation and utterance position. These findings suggest that the increased perceptual salience of the violation in utterance final position (due to phrase-final lengthening) influenced how S-V agreement violations were processed during sentence comprehension. Implications for the functional interpretation of language-related ERPs and experimental design are discussed.

Emotionality is increasingly given prominence in the field of language acquisition and socialization in migration contexts. This cross-sectional study explores the emotional experiences of Chinese and African immigrant families in their practices of maintaining their children's heritage languages. We used open-ended interviews, field notes from informal conversations and observations, photographic evidence of children's literacy practices, and language portrait (LP) descriptions, to collect data. Results from an ethnographic analysis of the data revealed a whole range of negative and positive parental emotions (e.g., anxiety, loss, shame vs. enjoyment, accomplishment, and pride), in the discourse of maintaining heritage and minority languages. We discuss the language emotions, whether positive or negative, in light of language ideologies, which specifically points to the significance of profit discourse in the formation of family language policies (FLPs). This materialistic valorization reveals the complexities of power relations between English and minority languages, between Chinese and African languages, and within various Chinese and African languages. Consequently, the distinct hierarchies between English and minority languages and the hidden layers within minority languages further legitimate diasporic ideologies of Chinese and African parents in terms of the emotionality associated with prioritizing, maintaining, and forgoing languages. These findings suggests that language emotionality is of vital importance to the psycho-social wellbeing of immigrant families and has practical implications for policymakers and heritage language research.
