Look and listen! The online processing of Korean case by native and non-native speakers

The L2 learners varied as concerns the typological proximity between their L1 (French or Kazakh) and Korean. Processing was compared for canonical (SOV) and scrambled (OSV) word order. Nominal case marking was either accusative (NOM-ACC) or dative (NOM-DAT). Native Koreans showed anticipatory looks to the correct image, regardless of word order or case. Neither L2 group showed anticipatory looks to the correct image prior to the final auditory verb. Both L2 groups demonstrated superior performance for the dative. However, the Kazakh group showed better capacities to correctly interpret utterances based on case than the French. Our results provide evidence of the incremental nature of processing in Korean for native speakers and, for L2 learners, the effect of L1-L2 overlap and specific case marking.

Processing metalinguistic negation: Evidence from eye-tracking experiments

It has been suggested that negation is interpreted as descriptive by default and that an MN interpretation is taken only after the DN interpretation turns out to be a semantic contradiction to the clarification clause (a semantic account). Another suggestion is that the type of negation is chosen by considering optimal relevance. That is, people take an interpretation that yields greater cognitive effects with less processing effort (a cognitive account). Eye-tracking experiments were conducted on MN-DN pairs that received similarly high ratings on sensicality: the first with external negation and the second with longform negation. In each pair, the two negative clauses were followed by the same clarification clause. In the experiments, clarification clauses showed no significant differences in the processing time between MNs and DNs. The results provide no evidence of the semantic account that the participants interpreted negation as descriptive by default. We suggest that they decided on the type of negation when they read the clarification clause, so that their processing times at the clarification clauses were not different between MNs and DNs, which is consistent with the cognitive account.

We examined the online processing of nominal case morphology in Korean by native speakers and L2 learners by contrasting canonical (SOV) and scrambled (OSV) structures, across auditory (Experiment 1) and written (Experiment 2) formats. Moreover, we compared different instances of nominal case marking: accusative (NOM-ACC) and dative (NOM-DAT). During auditory processing, Koreans showed incremental processing based on case information, with no effect of scrambling or specific case marking. In contrast, the L2 group showed no evidence of predictive processing and was negatively impacted by scrambling, especially for the accusative. During reading, both Koreans and the L2 group showed a cost of scrambling on first pass reading times, specifically for the dative. Las...
