During the recent pandemic, it became necessary to adapt lab-based studies to online experiments. To investigate the impact of online testing on the quality of data, we focus on three paradigms widely used in infant research: a word recognition task using the Intermodal Preferential Looking Paradigm, a word learning task using the Switch task, and a language assessment tool (WinG) where children identify a target word amongst a set of picture cards. Our results for synchronous and asynchronous studies provide support for the robustness of online testing. In Experiment 1, robust word recognition was found in 24-month-old toddlers. In Experiment 2, 17-month-old infants consistently learned a new word. Finally, Experiment 3 demonstrated that 19- to 26-month-old children performed well on a language assessment test administered online. Overall, effect sizes or language scores were found to be higher than in lab-based studies. These experiments point to promising possibilities for reaching out to families around the world.

This study explored monolingual and multilingual two- to five-year-olds' reliance on a non-verbal and a verbal cue during word-referent mapping, in relation to vocabulary knowledge and, for the multilinguals, Dutch language exposure. Ninety monolingual and sixty-seven multilingual children performed a referential conflict experiment that pitted a non-verbal (pointing) cue and a verbal (mutual exclusivity) cue. Mixed-effect regressions showed no main effects of vocabulary and language exposure. An interaction between vocabulary and group showed that lower vocabulary scores were associated with a stronger reliance on pointing over mutual exclusivity for multilinguals (but not monolinguals). Furthermore, an interaction between vocabulary, language exposure, and cue word (novel vs. familiar label) indicated that multilinguals with lower exposure and lower vocabulary showed a stronger reliance on pointing over mutual exclusivity when a novel rather than familiar word was used. These findings suggest that multilingual and monolingual children go through different trajectories when learning to map words to referents.

This scoping review aimed to investigate the communication strategies utilized by children who acquire a minority language (L1) and subsequently learn a community language (L2) during what is commonly referred to as the "silent period." Electronic database searches were conducted using keywords such as "silent period" and "bilingual children," resulting in the inclusion of 40 studies in the review. The findings revealed that emergent bilingual children utilize various communication strategies, including nonverbal communication, private speech, and their L1, to communicate within classroom environments. The findings shed light on the adaptability of emergent bilingual children during early stage of L2 acquisition. Furthermore, our review provides information about the classroom contexts such as teacher support and peer interactions where children develop their L2 skills. From a clinical perspective, recognizing these strategies and classroom contexts could significantly enhance the screening process for emergent bilingual children.

This study mapped the trajectory of developing derivational morphological knowledge in Hebrew monolingual and Russian-Hebrew bilingual children. We investigated 2^nd and 4^th graders, using a two-by-two structure along the dimensions of modality (comprehension, production) and type of word (real-word, pseudo-word). Performance in the morphological analogies comprehension tasks improved with grade, and monolingual and bilingual children performed equally well. A different pattern was evident in production tasks. In real-word production, monolingual children were more accurate than bilingual children, but this group difference narrowed with age. In pseudo-word production, monolingual children used more morphological elements than bilingual children, and there was also a tendency towards group differences narrowing with age. Detailed error analyses across all tasks revealed that monolingual children recruited more morphological elements than bilingual children. We present implications for assessment of morphological knowledge, and suggest that morphological intervention is a promising avenue for promoting bilingual children's success.

This study investigated how infants deal with cross-talker variability in the perception of native lexical tones, paying specific attention to developmental changes and the role of task demands. Using the habituation-based visual fixation procedures, we tested Cantonese-learning infants of different age groups on their ability to discriminate Cantonese Tone 1 (high level) and Tone 3 (mid level) produced by either multiple talkers or a single talker. Results demonstrated that the 12-month-old and 24-month-old groups showed reliable discrimination across talkers, whereas the 18-month-old group did not (Experiment 1), despite their ability to discriminate the same contrast when the talker was held constant (Experiment 2). In a task that included a novel object as a referent to the sound, the 18-month-olds discriminated the contrast across talkers from Tone 1 to Tone 3 (Experiment 3). These results revealed a U-shaped developmental path and perceptual asymmetry in native lexical tone discrimination across talkers.

Compounds (e.g., jellybeans) and list forms (e.g., jelly, beans) can be distinguished by the presence or absence of boundaries, marked by durational and pitch cues. Studies have shown that 5-year-olds learning English have acquired both cues for distinguishing compounds and lists. However, it is not clear how and when this ability is acquired by children speaking tonal languages, such as Mandarin. This study examined whether Mandarin-speaking preschoolers can use durational and pitch cues to distinguish compounds and lists and whether their productions are adult-like. Thirty-one 4-year-olds, 34 5-year-olds, 29 6-year-olds, and 43 adults participated in an elicited production experiment. Results showed that similar to English-speaking preschoolers, Mandarin-speaking preschoolers can use durational cues to mark boundaries, triggering appropriate pitch changes for distinguishing compounds and lists, though these were not fully adult-like, even in the oldest age group.

Time is frequently structured in terms of motion as moving-time (e.g., “summer is coming”), moving-ego (e.g., “we approach winter”), or sequence-as-position (e.g., “winter follows autumn”) across the world’s languages, including Chinese – a language that shows greater variability in its expression of such metaphors. Using a metaphor explanation and a metaphor comprehension task, we tested 60 children learning Chinese, equally divided into ages 3–4, 5–6, 7–8. Children’s performance improved with age, marking ages 7–8 as the period with significant gains in both comprehension and explanation of metaphors – a later mastery compared to children learning English shown in earlier work. Metaphor type also affected children’s performance, but only for the explanation and not the comprehension of metaphors. Overall, our findings highlight that the structure of spatial metaphors for time in Chinese influences the timing but not the trajectory of children’s development in learning spatial metaphors for time.

Co-speech gestures accompany or replace speech in communication. Studies investigating how autistic children understand them are scarce and inconsistent and often focus on decontextualized, iconic gestures. This study compared 73 three- to twelve-year-old autistic children with 73 neurotypical peers matched on age, non-verbal IQ, and morphosyntax. Specifically, we examined (1) their ability to understand deictic (i.e., pointing), iconic (e.g., gesturing ball), and conventional (e.g., gesturing hello) speechless video-taped gestures following verbal information in a narrative and (2) the impact of linguistic (e.g., vocabulary, morphosyntax) and cognitive factors (i.e., working memory) on their performance, to infer on the underlying mechanisms involved. Autistic children displayed overall good performance in gesture comprehension, although a small but significant difference advantage was observed in neurotypical children. Findings suggest that combining speech and gesture sequentially may be relatively spared in autism and might represent a way to alleviate the demand for simultaneous cross-modal processing.

Regional accent biases in 27 Essex five-year-olds are investigated. This study is the first to analyse implicit language attitudes by measuring children’s neural activity (event-related potentials) while they take part in an Implicit Association Test. Both measures find a preference towards the prestigious accent, Standard Southern British English (SSBE), which is associated with cleverness (CLEVER). A late positive potential in the brain data for the association of the familiar, low-prestige Essex accent with CLEVER suggests the children also have a positive association with their home accent. The association between the less familiar, low-prestige Yorkshire accent and either CLEVER or NOT-CLEVER depends on the measure. Differences in the results are found relating to the children’s accent exposure; those with a more heterogenous group of caretakers show more positive bias towards all three accents overall. Consequences for modelling the development of language attitudes are discussed.

The prolonged developmental window of irony understanding opens up the question of which socio-cognitive repertoire underlies this pragmatic capacity. In the present study, we investigated the relationship between epistemic vigilance and irony understanding in 5/6- and 6/7-year-old children using a picture selection task. We assessed children’s vigilance towards unreliable informants and manipulated the reliability of the irony target. Our findings confirm that irony comprehension is a late-emerging skill and highlight the need to differentiate its full-fledged understanding from mere sensitivity to contextual mismatches. While irony understanding was not affected by our reliability manipulation, our findings revealed that more vigilant children were better at irony understanding than less vigilant ones. This provides the first empirical evidence that epistemic vigilance is a good predictor of irony performance and lays the ground for future research on the intricate relationship between these two capacities.
