This study examined number marking comprehension among Japanese learners of L2 English, whose L1 does not have an obligatory number marking system. The study conducted an online sentence comprehension experiment with 96 L1-Japanese learners and 32 native speakers of English, wherein participants engaged in a self-paced reading with Stroop-like number judgment tasks. Participants were required to determine the number of single words in stimuli (e.g., _cat_/_cats_, one word; _the cats_/_the cat_, two-word sets), and their judgment time was measured for singular and plural words. The results indicated that both groups took more time to judge single plural nouns, suggesting that Japanese L2 learners of English automatically activate plurality in online sentence comprehension as native speakers do. In contrast, neither group showed an interference effect of singularity in judging singular two-word noun sets (_the cat_), unless the singularity is explicitly marked by indefinite article (_a cat_). The lack of interference may be because of unmarkedness of singularity.

Investigation of the relationship between animacy and L2 learners’ acquisition of the English plural morpheme
It has been argued that languages differ in the extent to which they allow plural forms of nouns according to the Animacy Hierarchy. Japanese distinguishes between animate and inanimate nouns; the latter are less likely to receive plural markers (e.g., ? hon‐tachi), unlike English. This L1‐L2 difference might cause difficulty in acquiring the plural morpheme. The present study thus investigates the influence of animacy on the processing of the English plural morpheme in online sentence processing. In this study, 34 Japanese university students engaged in a moving window version of a self-paced reading task, during which they also judged whether the number of words presented was one or two when prompted. If animacy matters, Japanese EFL learners might not show an interference effect of this second task for inanimate nouns. However, as no such effect was found, the prediction based on the animacy hierarchy was not confirmed.

Rule-based or efficiency-driven processing of expletive there in English as a foreign language
Although Native speakers (NSs) of English make plural agreement in preverbal-subject sentences (e.g., A pen and eraser *is/are…), previous studies have demonstrated that they prefer singular – not plural – agreement between verbs and conjoined noun phrases (NPs) in expletive there constructions (e.g., there is/are a pen and an eraser…), showing efficiency-driven processing prioritization of agreement between nearest constituents. This paper assesses whether Japanese L2 learners of English (JLE) show this tendency. The results of two self-paced reading experiments together indicated that even though efficiency-driven processing was available to L2 learners, their use was unstable due to the repeated exposure to there are NPpl– and NPpl-type sentences during the task. It seems possible that repeated exposure triggered learners’ knowledge that that conjoined NPs are always plural. Hence, it could conceivably be hypothesized that a learner’s specific knowledge intervenes the efficiency-driven processing strategy.

L2 learners’ number agreement in the expletive there constructions: Conjoined NP always plural?
The purpose of this study was to investigate whether L2 learners of English can employ efficiency-driven number agreement processing with conjoined noun phrases (NPs) in expletive there constructions (ETC). Previous studies reported that native speakers of English prefer singular agreement over plural agreement when conjoined NPs are used in ETCs (e.g., there is a pen and an eraser…), which implies that native speakers (NSs) of English prioritize efficiency over the canonical agreement. The present study examined whether L2 learners can show similar processing tendencies. In Experiment 1, an offline error correction task was administered to Japanese L2 learners of English to see the learners’ explicit knowledge. The results indicated that they tend to make a plural agreement in ETCs. In Experiment 2, L2 learners were compared with NSs in the self-paced reading task, which demonstrated that—unlike the NS group—L2 learner group analyzed conjoined NPs as a plural. The fact that L2 learners preferred plural agreement could be due to their explicit knowledge that conjoined NP should always be plural. This knowledge led to a non-nativelike agreement in ETC in online sentence processing.
