“…These data were part of a larger study where parents were asked to contribute data longitudinally on a monthly basis from 16 to 30 months of age (note that there were some missing data, discussed further below). This age range corresponds to that for the MacArthur-Bates Communicative Development Inventories (CDI): Words and Sentences Forms (Boudreault et al, 2007;Marchman et al, 2023). Most parents had at least some postsecondary education, and family incomes were generally high: 50% of families had a disclosed yearly income greater than 100,000 Canadian dollars, and 95% of families had disclosed yearly incomes of greater than 50,000 Canadian dollars, which is above the Statistics Canada (2023) low-income cutoff for a family of four in large urban centers.…”

Sometime before their second birthday, many children have a period of rapid expressive vocabulary growth called the vocabulary spurt. Theories of the underlying mechanisms differ: Accumulator models emphasize the accumulation of experience with words over time to yield a spurtlike pattern, while cognitive models attribute the spurt to cognitive changes. To test these theories, English-French monolingual and bilingual children with different exposure to each language were studied. Dense, longitudinal data were analyzed from 45 infants aged 16-30 months, whose expressive vocabulary was measured on a total of 617 occasions in English and/or French. Single-language (English and/or French), concept (number of concepts lexicalized across both languages), and word (sum of both languages) vocabulary scores were computed. Infants' exposure to each language and their exposure balance were measured using a language exposure questionnaire. Logistic curves were fitted to each infant's data to estimate the timing (midpoint) and steepness (slope) of the vocabulary spurt in single-language, concept, and word vocabularies. Seventy-six percent of infants showed a spurt in at least one vocabulary type, and bilinguals were less likely to show one in their nondominant than their dominant language. For single-language vocabulary, infants with more exposure to a language had earlier spurts. For combined vocabularies (concept and word), monolinguals and unbalanced bilinguals had earlier and steeper spurts than balanced bilinguals. Results better support the predictions of accumulator models than cognitive theories and show that infants follow different vocabulary acquisition trajectories based on their language background. Public Significance StatementA growing number of children are being raised bilingual, but they continue to be underrepresented in language research. This study highlights the influence of bilingual language exposure on vocabulary acquisition in infancy, showing that bilingualism alters the expected timing and magnitude of the vocabulary spurt. Our findings will help families raising bilingual children, educators, and health care professionals to accurately assess early language milestones and better identify potential language delays.

“…Secondary outcomes were biochemical and clinical parameters, as well as change in electroencephalogram (EEG). Neurological and psychiatric examinations were included in the clinical evaluation, in addition to a standardized assessment of gastrointestinal symptoms using the GSI ( 28 ); autism severity through ADOS-2 ( 29 ), Childhood Autism Rating Scale (CARS) ( 30 ), and Social Communication Questionnaire (SCQ) ( 31 ); limited and repetitive actions utilizing the Revised Repetitive Behavior Scale (RBSR) ( 32 ); screening for emotional, behavioral, and social issues with the Child Behavior Checklist (CBCL) ( 33 ); improvements in one’s mental faculties as measured by means of the Griffiths Mental Development Scales-Extended Revised (GMDS-R) ( 34 ); improvement in adaptive skills as measured by the Vineland Adaptive Behavior Scales-II ( 35 ); language abilities can be assessed using the McArthur-Bates Communicative Development Inventories (CDI) ( 36 ).…”

Background and objectiveThe potential impact of gut health on general physical and mental well-being, particularly in relation to brain function, has led to a growing interest in the potential health advantages of prebiotics, probiotics, and synbiotics for the management of ASD. A comprehensive meta-analysis and systematic review was conducted in order to evaluate the effectiveness and protection of many drugs targeted at manipulating the microbiota in the treatment of ASD.MethodsThe present study employed a comprehensive examination of various electronic databases yielded a total of 3,393 records that were deemed possibly pertinent to the study. RCTs encompassed a total of 720 individuals between the ages of 2 and 17, as well as 112 adults and participants ranging from 5 to 55 years old, all of whom had received a diagnosis of ASD.ResultsOverall, 10 studies reported Autism-Related Behavioral Symptoms (ARBS). Regarding the enhancement of autism-related behavioral symptoms, there wasn’t a statistically significant difference between the intervention groups (combined standardized mean difference = −0.07, 95% confidence interval: −0.39 to 0.24, Z = 0.46, p = 0.65). We observed that in the patients with ASD treated with probiotic frontopolar’s power decreased significantly from baseline to endpoints in beta band (Baseline: 13.09 ± 3.46, vs. endpoint: 10.75 ± 2.42, p = 0.043, respectively) and gamma band (Baseline: 5.80 ± 2.42, vs. endpoint: 4.63 ± 1.39, p = 0.033, respectively). Among all tested biochemical measures, a significant negative correlation was found between frontopolar coherence in the gamma band and TNF-α (r = −0.30, p = 0.04).ConclusionThe existing body of research provides a comprehensive analysis of the developing evidence that indicates the potential of probiotics, prebiotics, and synbiotics as therapeutic therapies for ASD. Our findings revealed that those there was no significant effect of such therapy on autism-related behavioral symptoms, it has significant effect on the brain connectivity through frontopolar power in beta and gamma bands mediated by chemicals and cytokines, such as TNF-α. The psychobiotics showed no serious side-effects.

“…For example, Bakker et al (2023) found evidence for differences in the pattern of prediction to numeracy from other cognitive measures at the high end of the distribution with that in the low-and average-range. We are not aware of any research on either extreme of math vocabulary in the preschool period, although there is much evidence for very substantial variability in general vocabulary (Marchman and Dale, 2023). Research on math difficulties, which may include children with a diagnosed disability related to math or those struggling with instruction or both, begins in the kindergarten period at the earliest (Nelson and Power, 2018).…”

There are well-documented associations between numeracy development in preschool age children and general and math vocabulary, literacy, and executive functions. However, the studies have largely included small samples of children with parents with either predominantly low or higher socioeconomic background (SES); further, few studies have included measures of all these domains in the same analyses. In this current study, we examined how general vocabulary, math vocabulary, rhyme detection and three measures of executive functions are associated with numeracy development in a population representative sample of 2,931 Danish children 3–5 years (51% male, 89% white). Multi-level regressions controlling for child age and, sex, and in some analyses also parental education and income confirmed that general vocabulary (β = 0.16), math language (β = 0.17), rhyme detection (β = 0.14), attention shifting (β = 0.09), inhibitory control (β = 0.05), and working memory (β = 0.09) each are associated with numeracy after controlling for covariates when estimated in the same model. Analyses of extreme performance (low-high) suggests a much closer and symmetrical connection between math language and numeracy compared to that between general vocabulary and numeracy. Interestingly, family SES is weakly but significantly related to all measures, most strongly for the vocabulary measures, but does not influence the pattern of results from regression analyses. In conclusion, both general vocabulary and mathematics-specific vocabulary contribute substantially to early numeracy skills. Rhyme detection and executive functions are also associated with numeracy skills, but with a lower magnitude.
