Most second language acquisition (SLA) research has documented the processes involved in learning second/foreign languages, with few studies focusing on the durability of attained second language (L2) skills once instructed learners/users are no longer receiving formal instruction. The current study examines the effects of continued exposure and peak instructional attainment on the long-term evolution of advanced, instructed L2 learners’ skills following a longitudinal mixed-methods research design. Participants (n = 28) completed an oral proficiency test, an oral interview, and a vocabulary knowledge test at multiple times over an 8-year period, 6 years of which were postinstruction. Results showed that continued exposure contributes to long-term retention (and some further development) of oral proficiency and fluency and that peak attainment at the end of formal instruction is also an important variable for some areas of L2 performance. Additionally, even the participants with limited exposure demonstrated little attrition over time.

This study examined the influence of cognate status and language distance on simultaneous bilingual children's vocabulary acquisition. It aimed to tease apart effects of word-level similarities and language-level similarities, while also exploring the role of individual-level variation in age, exposure, and nontarget language proficiency. Children simultaneously acquiring two closely related languages (n = 203) or two more distant languages (n = 109) performed extended versions of the LITMUS Cross-Linguistic Lexical Task (Haman et al., 2015), a productive vocabulary test with words varying in their phonological similarity to their translation equivalents. Children speaking closely related languages obtained higher vocabulary scores than children speaking more distant languages, who showed a stronger positive effect of phonological similarity. The effect of language distance on vocabulary was not solely driven by the presence of (near-)identical cognates in the test. These findings show that similarities beyond specific test items and/or beyond the phonological level play a role in vocabulary acquisition.

Collocational priming is a priming effect induced by collocationally related words; it has been taken to explain the cognitive reality of collocation. Collocational priming has largely been observed in first language (L1) speakers, whereas work on the representation of collocation in a second language (L2) is still limited. In the present study, we sought to investigate this phenomenon in L1 and L2 speakers of Italian. We used a lexical decision task to explore collocational priming in verb–noun and noun–adjective collocations differing in frequency and collocational strength. Both L1 and L2 speakers were found sensitive to the frequency of collocations. Importantly, exposure to L2 Italian was found to play a role. The results suggest that collocational priming occurs both in L1 and L2 speakers, and that the mechanisms associated with collocation processing and representation in L1 and L2 speakers may be comparable.

For Spanish nouns, masculine gender is unmarked and feminine is marked. Effects of markedness on gender agreement processing are inconsistent, possibly owing to differences between online methods. This study presents a reanalysis of eye-tracking data from Keating's (2022) study on the processing of noun-adjective gender agreement in speakers of Spanish as a majority and a heritage language. Pairwise comparisons by noun class showed that both groups displayed sensitivity to gender violations with masculine nouns earlier in the time course of agreement processing than they did to violations with feminine nouns, although sensitivity to errors with both classes emerged later for heritage speakers. The time course advantage for detecting gender violations with masculine nouns disappeared when a word occurred between nouns and adjectives. In sum, the native Spanish parser utilizes markedness information during online computation of gender agreement dependencies, even when exposure to native language input is significantly reduced.

In a recent study, preschoolers adapted their syntactic expectations about a familiar phrase in French; this adaptation affected later word learning. In two experiments, we probed the generality of this finding by replicating the experiment and extending it to a different expression in English. We examined the ambiguous phrase the baby, which can be followed by nouns (the baby monkeys) or verbs (the baby sleeps). In induction trials, the baby consistently preceded either familiar nouns (noun condition) or verbs (verb condition). In later novel-word trials, children in the verb condition were more likely to interpret novel words following the baby (The baby gorps!) as verbs than were children in the noun condition. In Experiment 2, a modified design isolated the effect of experience with the critical phrase from possible effects of task structure, and an added baseline condition showed the adaptation effect to be asymmetrical, suggesting frequency or surprisal effects on adaptation.

Adults learning a new language tend to judge unconventional utterances more leniently than fluent speakers do; ratings on acceptable utterances, however, tend to align more closely with fluent speakers. This asymmetry raises a question as to whether unconventional utterances can be statistically preempted by conventional utterances for adult learners. We report a preregistered study that provided undergraduates in Spanish classes with three days of exposure to conventional Spanish sentences without feedback. Judgment data reveal a significant effect of statistical preemption, particularly on intermediate learners, as predicted: Repeatedly witnessing conventional sentences led learners to subsequently judge as significantly lower the corresponding unconventional formulations in comparison to unrelated unconventional sentences. Current findings indicate that adult learners can take advantage of statistical preemption to learn the unacceptability of unconventional sentences from repeated exposure to acceptable alternatives, without explicit instruction or feedback.

This study explored the effects of practice schedule on the processing of new second language (L2) vocabulary and resulting knowledge. Participants were 107 low-achieving adolescents attending a vocational high school in Korea. They were randomly assigned to one of three practice groups and completed a L2 English–L1 Korean paired-associates learning task. The blocking group practiced one word at a time before switching to different words (e.g., A/A/A/B/B/B/C/C/C); the interleaving group practiced multiple words in sequence (e.g., A/B/C/A/B/C/A/B/C); and the hybrid group had both blocked and interleaved practice. Results revealed that (a) interleaved practice alone posed undesirable difficulty for low achievers, (b) blocked practice in the early learning phase facilitated the development of new declarative knowledge, and (c) hybrid practice produced more robust long-term retention than blocking and interleaving. The findings are discussed in relation to real-time processing accuracy, reaction time, coefficient of variation, and meaning recognition test outcomes. Additionally, I explore possible applications of these findings in developing optimal algorithm-based software for vocabulary learning.

Concrete symbols (e.g., sun, run) can be learned in the context of objects and actions, thereby grounding their meaning in the world. However, it is controversial whether a comparable avenue to semantic learning exists for abstract symbols (e.g., democracy). When we simulated the putative brain mechanisms of conceptual/semantic grounding using brain-constrained deep neural networks, the learning of instances of concrete concepts outside of language contexts led to robust neural circuits generating substantial and prolonged activations. In contrast, the learning of instances of abstract concepts yielded much reduced and only short-lived activity. Crucially, when conceptual instances were learned in the context of wordforms, circuit activations became robust and long-lasting for both concrete and abstract meanings. These results indicate that, although the neural correlates of concrete conceptual representations can be built from grounding experiences alone, abstract concept formation at the neurobiological level is enabled by and requires the correlated presence of linguistic forms.

What is the relationship between literacy skills and implicit learning? To address previous mixed findings, we compared school-aged readers, typical (CON, n = 54) and with dyslexia (DYS, n = 53), in relation to their performance on a serial reaction time task. For the first time, we also included an isolated spelling deficit group (ISD, n = 30) to control for distinctive effects of reading and spelling deficits. A linear reaction times analysis did not reveal between-group differences in implicit learning. However, further examination revealed that most CON (65%) and ISD (63%) were implicit learners, whereas most DYS were nonlearners (64%). Brain activity showed differences in early learning phases: CON learners and DYS nonlearners activated the left inferior frontal gyrus (IFG) and left insula more than other groups. Our findings imply that implicit learning is more frequently disrupted in children with dyslexia than in typical readers, and that activation of the left IFG and insula contributes to effective learning in the latter group but it does not in the former.

Taza in Spanish refers to cups and mugs in English, whereas glass refers to different glass types in Spanish: copa and vaso. It is still unclear whether such categorical distinctions induce early perceptual differences in speakers of different languages. In this study, for the first time, we report symmetrical effects of terminology on preattentive indices of categorical perception across languages. Native speakers of English or Spanish saw arrays of cups, mugs, copas, and vasos flashed in streams. Visual mismatch negativity, an implicit electrophysiological correlate of perceptual change in the peripheral visual field, was modulated for categorical contrasts marked in the participants’ native language but not for objects designated by the same label. Conversely, P3a, an index of attentional orienting, was modulated only for missing contrasts in the participants’ native language. Thus, whereas native labels influenced participants’ preattentive perceptual encoding of objects, nonverbally encoded dissociations reoriented their attention at a later processing stage.
