The purpose of this study was to examine early fast mapping abilities in late talkers (LT) and typically developing (TD) Spanish-speaking children by considering the effect of different variables on fast mapping (age, vocabulary level, grammatical category and number morphology). Thirty-eight Spanish-speaking children were assessed at three times (21 to 24 months at the beginning of the study). A group of LT was matched in age with a TD control group. They completed a fast mapping task with a disambiguation phase and an extension phase. Results show that vocabulary level and age interact with grammatical category and number morphology. TD children’s performance was significantly higher than LT children’s, but these differences decreased with age. Results suggest that the incorporation of new labels does not work automatically; some children may need repeated exposures to word–referent pairings. Longitudinal results suggest the importance of looking at the dynamics of lexical acquisition in addition to vocabulary size.

Abstract This study compares the lexical composition of 118 children with autism spectrum disorder (ASD) aged 12 to 84 months with 4626 vocabulary-matched typically developing toddlers with and without language delay, aged 8 to 30 months. Children with ASD and late talkers showed a weaker noun bias. Additionally, differences were identified in the proportion of nouns and verbs, and in the semantic categories of animals, toys, household items and vehicles. Most differences appear to reflect the extent of the age differences between the groups. However, children with ASD produced fewer high-social verbs than typical talkers and late talkers, a difference that might be associated with ASD features. In sum, our findings identified areas of overlap and distinction across the developing lexical profiles.

Expressive language outcomes measured by MLU and the Index of Productive Syntax (IPSyn) at ages 3;0 and 4;0 were investigated in 34 late talkers with normal receptive language identified between 2;0 to 2;7 and 16 typically developing comparison children matched on age, SES, and nonverbal ability. Late talkers made greater gains than comparison children between 3;0 and 4;0 in both MLU and IPSyn raw score. However, when age-standardized z-scores were analysed, the late talkers were about 2·5 standard deviations below comparison children on both measures at both ages. At 3;0, 41% of the late talkers had MLUs above the 10th percentile based on Scarborough's (1990) benchmark sample; by 4;0, 71% did so. Using the IPSyn, a more stringent measure, 34% scored above the 10th percentile at 3;0 and only 29% did so at 4;0. MLU was significantly correlated with the IPSyn at both ages for the late talkers, but only at 3;0 for the comparison children. A converging set of regression analyses indicated no group differences in the predictive relationship between MLU and IPSyn, suggesting that the late talkers were delayed on both measures but not deviant in their development.

ABSTRACTThis study investigated vocabulary size and vocabulary composition in Greek children aged 1 ; 6 to 2 ; 11 using a Greek adaptation of Rescorla's Language Development Survey (LDS; Rescorla, 1989). Participants were 273 toddlers coming from monolingual Greek-speaking families. Greek LDS data were compared with US LDS data obtained from the instrument's normative sample (Achenbach & Rescorla, 2000). Vocabulary size increased markedly with age, but Greek toddlers appeared to get off to a slower start in early word learning than US children. The correlation between percentage word use scores in Greek and US samples was moderate in size, indicating considerable overlap but some differences. Common nouns were the largest category among the fifty most frequent words in both samples. Numbers of adjectives and verbs were comparable across languages, but people and closed-class words were more numerous in the Greek sample. Finally, Greek late talkers showed similar patterns of vocabulary composition to those observed in typically developing Greek children.

AbstractThe purpose of this study was to examine attention allocation in toddlers who were late talkers and toddlers with typical language development while they were engaged in a word-learning task in order to determine if differences exist. Two-year-olds who were late talkers (11) and typically developing toddlers (11) were taught twelve novel pseudo-words for unfamiliar objects over ten training sessions. The toddlers' attention allocation during the word-learning sessions was measured as well as their comprehension of the newly learned words. Late talkers showed reduced attention allocation to objects during word-training sessions, and also comprehended fewer of the novel words than toddlers with typical language development. Attention allocation was found to be a stronger predictor of word learning as compared to cognition and auditory comprehension. Reduced attention allocation may contribute to the early lexical delay characteristic in late talkers.

Relevance. The article discusses the relationship between the development of joint (shared) attention of a child with an adult, and the social and cognitive development of the child. Based on previous studies of typically developing children that demonstrate their participation and responsiveness to fundamental social characteristics, it is significant to identify manifestations of atypical joint attention when a child does not register which object (event) or which aspects of this object (event) are the focus of an interlocutor’s attention. The question of which aspects of joint attention are related to the normative development of the child makes this relevant for comparing groups with different forms of atypical development. For the study, the main indicator of understanding the intentions of the other in the direction of view was used, as one of the aspects of joint attention. Objective. To compare the development of social cognition and joint attention among typically developing children and children with various forms of atypical development in order to identify the correlation between the theory of mind and cognitive lesion. Methods. In a sample of preschool children with typical development and of those with mental retardation, hearing impairment, speech impairment, or visual impairment (N = 90), the following methods were used to evaluate the children’s understanding of the intentions, desires, and interests of others by their behavioral manifestations: “Test for Erroneous Opinion”, “Sally-Ann”; the “What does Charlie want?” task, and others. The task was also used to assess the child’s ability to use the direction of a character’s gaze in a picture to determine the person’s intentions. Results. We identified the “primary psychological” characteristics of the atypical development of the child, which prioritize violations of social communication. Several variations of the violation of joint attention were singled out by determining a person’s intentions by the direction of their gaze. It was shown that determining intentions by the direction of gaze is associated with the normative age formation of the child. Symptoms of deficiency in this skill vary depending on the specifics of the child’s atypical development. Conclusions. Secondary deviations in the development of social cognition are specific to a particular primary defect. The limited inflow of information in the event of a violation of the analyzer creates unusual conditions in the children’s accumulation of the experience of social interaction that is necessary to form a mental model.

Many studies demonstrate that in typically developing (TD) children joint attention constitutes a prerequisite for language development. However, data on the development of joint attention and its relation to language development in Down syndrome (DS) are contradictory. The present study aims to examine joint attention in toddlers with DS as well as its association with language comprehension and production. Participants were 10 toddlers with DS (mean chronological age: 58 months) and 10 TD toddlers matched for language comprehension (mean chronological age: 32 months). Language Comprehension and language production were assessed using the Müllen Scales of Early Learning, expressive vocabulary was assessed using the Language Development Survey, and the communicative behaviors were assessed through observation of interactions with the mother in a semi-structured condition with toys. According to the findings, toddlers with DS exhibit significantly morejoint attention behaviors compared to TD toddlers. Moreover, it was shown that in toddlers with DS language production was significantly negatively correlated with initiating request gestures. Conclusively, it seems that in toddlers with DS the transition from pre-linguistic to linguistic period follows a similar developmental path as in TD toddlers, although a severe delay is observed.
