Event segmentation tests have shown substantial overlaps in how adults recognize starts and endpoints as events unfold. However, far less is known about what role different language systems play in the process. Variations in grammatical aspect have been shown to influence event processing. We tested how closely first language (L1) speakers of…

In this paper, we report a longitudinal study of the effects of procedural task repetition on learners' task performance (i.e., syntactic complexity in relation to lexical complexity). We investigated how task repetition results in differences at the group and individual level across each task interval (T = 7). Intermediate-level Saudi learners of…

Previous studies have shown that prior linguistic knowledge affects semantic implicit learning when stimuli are presented in the first language. We report an experiment that investigated whether such crosslinguistic influence from the first language would still emerge in the second language for semantic implicit learning of novel articles and…

This study investigated how students' self-reported individual differences predicted second language (L2) spoken discussion task output, an objective behavioral outcome, in the Japanese university English as a Foreign Language (EFL) context. Although numerous psychological theories are used as a rationale for task-based language teaching (TBLT),…

Second language (L2) speakers often experience difficulties in learning words with L2-specific phonemes due to the unfaithful lexical encoding predicted by the fuzzy lexical representations hypothesis. Currently, there is limited understanding of how allophonic variation in the first language (L1) influences L2 phonological and lexical encoding.…

A central question in multilingualism research is how multiple languages interact. Most studies have focused on first (L1) and second language (L2) effects on a third language (L3), but a small number of studies dedicated to the opposite transfer direction have suggested stronger L3 influence on L2 than on L1 in postpuberty learners. In our study,…

Several previous studies showed that prime-target pairs with orthographical overlap but no semantic or morphological relationship (e.g., freeze-free) produced a masked priming effect in second language (L2) speakers but not in first language (L1) speakers. The present study further explored this intriguing L1-L2 difference by comparing English…

Some listeners exhibit higher sensitivity to subphonemic acoustic differences (i.e., higher speech gradiency). Here, we asked whether higher gradiency in a listener's first language (L1) facilitates foreign language learning and explored the possible sources of individual differences in L1 gradiency. To address these questions, we tested 164…

Extending previous findings on adult L2 learners' integration of verbal and constructional information, this study investigated how child learners of English as a foreign language produce verbs in target constructions and whether (a) receptive skills and (b) the specific production modality (spoken versus written) modulate the integration process.…

The current study investigated the effects of repetition on the learning of second language (L2) spoken word forms. Japanese university students learning L2 English were randomly assigned to one of three treatment conditions (one, three, and six exposures) and learned 40 words while hearing them and viewing their corresponding pictures. A…

This article examines the performance of heritage speakers on a bimodal acceptability judgment task that targeted morphologically complex words. A major goal of the study was to compare participants' acceptance of conventional and creative words. Data were collected from 57 adult heritage speakers of Spanish who were subsequently divided into two…

This study investigated the effects of individual word frequency, collocational frequency, and association on L1 and L2 collocational processing. An acceptability judgment task was administered to L1 and L2 speakers of English. Response times were analyzed using mixed-effects modeling for 3 types of adjective-noun pairs: (a) high-frequency, (b)…

The current study examined the degree to which collocation use (i.e., meaningful co-occurrences of multiple words) is related to first language (L1) raters' intuitive judgments of second language (L2) speech. Speech samples from a picture description task performed by 85 Japanese learners of English with varied L2 proficiency profiles were…

The constructionist approach holds that an argument structure construction, a conventionalized form-meaning correspondence of a sentence, allows language users to efficiently access sentential information. This study investigated whether increased sensitivity to constructional information would enable second language learners to efficiently fuse…

Languages often use different constructions to convey the same meaning. For example, the meaning of a causative construction in English ("Jen had her computer fixed") is conveyed using an active structure in Korean ("Jen-NOM her computer-ACC fixed"), and yet little is known about how bilinguals represent and process such…
