ABSTRACT Grammatical aspect captures ways in which a language uses grammatical markers to describe the temporal structure of an event. An event-related potential experiment was conducted to investigate event-related potential correlates of agreement violations of Chinese grammatical aspect. Participants read sentences containing either aspect agreement violations, semantic violations, or no violations. Semantic violations elicited an N400, whereas aspectual violations elicited a 200-400 ms posterior and left central negativity, followed by a P600, instead of left anterior negativity or N400, suggesting that left anterior negativities may not reflect a general, rule-governed, syntactically compositional process, and that grammatical aspect processing is at least not completely semantically driven. The negativity mostly reflects a failure to bind aspect markers or the detection of aspectual errors.

    ABSTRACT: Human languages are equipped with an impressive repertoire of time-encoding devices which vary significantly across different cultures. Previous research on temporal processing has focused on morphosyntactic processes in Indo-European languages. This study investigated the neural correlates of temporal processing in Mandarin Chinese, a language that is not morphologically marked for tense. In a sentence acceptability judgment task, we manipulated the agreement between semantically enriched temporal adverbs or a highly grammaticalized aspectual particle (-guo) and temporal noun phrases. Disagreement of both the temporal adverbs and the aspectual particle elicited a centro-parietal P600 effect in event-related potentials (ERPs) whereas only disagreeing temporal adverbs evoked an additional broadly distributed N400 effect. Moreover, a sustained negativity effect was observed on both the words following the critical ones and the last words in sentences with temporal disagreement. These results reveal both commonalities and differences between Chinese and Indo-European languages in temporal agreement processing. In particular, we demonstrate that temporal reference in Chinese relies on both lexical semantics and morphosyntactic processes and that the level of grammaticalization of linguistic devices representing similar temporal information is reflected in differential ERP responses.

    ABSTRACT: Although there is broad agreement that error signals generated during an unexpected linguistic event are reflected in event-related potential (ERP) components, there are at least two distinct aspects of the process that the ERP signals may reflect. The first is the content of an error, which is the local discrepancy between an observed form and any expectations about upcoming forms, without any reference to why those expectations were held. The second aspect is the cause of an error, which is a context-aware analysis of why the error arose. The current study examines the processes involved in prediction of morphological marking on verbal forms in Hindi, a split ergative language. This is a case where an error with the same local characteristics (illicit morphology) can arise from very different cues: one syntactic in origin (ergative case marking), and the other semantic in origin (a past tense adverbial). Results suggest that the parser indeed tracks the cause in addition to the content of errors. Despite the fact that the critical manipulation of verb marking was identical across cue types, the nature of the cue led to distinct patterns of ERPs in response to anomalous verbal morphology. When verbal morphology was predicted based upon semantic cues, an incorrect future tense form elicited an early negativity in the 200–400 ms interval with a posterior distribution along with a marginally significant P600 effect. In contrast, when verbal morphology was predicted based upon morphosyntactic cues, an incorrect future tense form elicited a right-lateralised anterior negativity (RAN) during the 300–500 ms interval, as well as a P600 response with a broad distribution.

    ABSTRACT: a b s t r a c t The present study used magnetoencephalographic neuroimaging to examine the neural correlates supporting the processing of a negative polarity item (NPI) (renhe) in Mandarin Chinese. Participants monitored the appearance of a catch word in sen-tences while their brain activities during the processing of the NPI or a perfective aspect marker (-le) were recorded. The results revealed that the NPI in a non-downward entailing context elicited a larger M350 component, possibly reflecting the cost of semantic integration. As a contrast, sentences violating grammatical aspects elicited greater brain responses in a later time window between 500 and 600 ms. The present findings not only demonstrate a clear distinction between semantic and syntactic processing in disso-ciable time courses, but further indicate that the processing of negative polarity items in Chinese is mainly constrained by the conditions imposed by semantic context.
