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.

Adults rate the speech of children assigned male at birth (AMAB) and assigned female at birth (AFAB) as young as 2.5 years of age differently on a scale of definitely a boy to definitely a girl (Munson et al., 2022), despite the lack of consistent sex dimorphism in children's speech production mechanisms. This study used longitudinal data to examine the acoustic differences between AMAB and AFAB children and the association between the acoustic measures and perceived gender ratings of children's speech. We found differences between AMAB and AFAB children in two acoustic parameters that mark gender in adult speech: the spectral centroid of /s/ and the overall scaling of resonant frequencies in vowels. These results demonstrate that children as young as 3 years old speak in ways that reflect their sex assigned at birth. We interpret this as evidence that children manipulate their speech apparatus volitionally to mark gender through speech.

We investigate the effects of age and first language (L1) on the acquisition of verb morphology in L2 English by Chinese and Russian children learning English as a foreign language in EFL schools in Shanghai and Moscow. We tested children 5 years after they started their EFL classes and considered two groups in each country: one group started EFL classes at the age of 4 and was tested at the age of 9, while the other group started at 7 and was tested at 12. We assessed the production of 3SG-agreement and past tense using two elicited production tasks (TEGI). Our results show that later starters consistently outperform earlier starters. Unexpectedly, Chinese children showed higher accuracy with 3SG-agreement than their Russian counterparts. Finally, learners were more accurate with regular past tense than 3SG-agreement.

The main aim of this study, which presents the Slovenian adaptation of the Macarthur-Bates Communicative Development Inventory CDI–III, was to investigate the characteristics of language development in monolingual Slovenian-speaking children aged 30–48 months. In addition, we examined the relationships between different measures of child language assessed by the CDI–III, namely vocabulary, grammar and metalanguage. The sample comprised 301 children whose language was assessed by their parents using the Slovenian version of the CDI–III. The results indicate that language development at this age continues to progress relatively quickly, particularly in terms of children’s metalinguistic abilities, although there are large individual differences in language ability between children of the same age. The findings also indicate that some of the pre-existing relationships established between the different domains of infant and toddler language ability persist into early childhood, with vocabulary emerging as an important predictor of children’s grammar.

How do children learn the language-to-concept mappings within the domain of Mechanical Support – a spatial domain involving varied and complex force-dynamic relations between objects based on specific mechanisms (stickiness, clips, etc.)? We explore how four- and six-year-olds, and adults encode dynamic events and static configurations of Mechanical Support via attachment (picture put on a door). Participants viewed spatial configurations (Experiment 1 – in dynamic events or Experiment 2 – in static states) and were then prompted with the question, “Can you tell me what my sister did with my toy?” Children and adults used lexical verbs, and the visibility of the mechanism influenced the type of verb used. Also, whereas children preferentially used Orientation Verbs (e.g., “hang”), adults preferentially used Verbs of Attaching (e.g., “tape,” “stick”). Our findings shed light on how children acquire mechanical support language and the linguistic and cognitive constraints involved.

This study assessed the relationship between preschoolers' directly and indirectly assessed emotion word comprehension. Forty-nine two-to-five-year-old Norwegian children were assessed in a tablet-based 4-alternative forced choice (AFC) task on their comprehension of six basic and six complex emotions using facial expression photographs. Parents reported emotion word comprehension and production of the same words. Parent-reported emotion word production interacted with age to predict preschoolers' performance, with a parent-child alignment only observed for older children. Parent-reported word comprehension did not significantly predict accuracy. The results suggest that, in preschoolers, direct and indirect assessments might address distinct representational levels of emotion word comprehension.
