“…Inclusion criteria were identical to our previous studies of this population 41,[46][47][48][49][50][51][52] . Speci cally, we selected participants based on the following criteria 1) Consistency: Participants' caregivers must have lled out at least three evaluations, and the interval between the rst and the last evaluation was six months or longer.…”

Typical children demonstrate nearly constant syntactic language learning-rate, as measured by a parent-reported Mental Synthesis Evaluation Checklist (MSEC), from 2 to 6 years of age and reach the ceiling MSEC score around 8 years of age 1. In this study we report syntactic language learning-rate (measured as MSEC score change per year) in 15,183 autistic individuals of 2 to 22 years of age. Of these, 98.5% participants did not reach the ceiling MSEC score. Computational models used to estimate the trajectory of underlying learning-rate showed that unlike a constant syntactic language learning-rate in typical children, which is observed until at least 6 years of age, learning-rate in autistic individuals declined exponentially starting from 2.3 years of age. Furthermore, this decline started earlier in more severe forms of autism. One possible explanation for this difference is a shorter critical period for syntactic language acquisition in autistic children compared to typical controls. This early closing of the critical period may explain lifelong syntactic language deficits in some autistic individuals.

Prefrontal synthesis (PFS) is a component of constructive imagination. It is defined as the process of mentally juxtaposing objects into novel combinations. For example, to comprehend the instruction "put the cat under the dog and above the monkey," it is necessary to use PFS in order to correctly determine the spatial arrangement of the cat, dog, and monkey with relation to one another. The acquisition of PFS hinges on the use of combinatorial language during early development in childhood. Accordingly, children with developmental delays exhibit a deficit in PFS, and frequent assessments are recommended for these individuals. In 2018, we developed the Mental Synthesis Evaluation Checklist (MSEC), a parent-reported evaluation designed to assess PFS and combinatorial language comprehension. In this manuscript we use MSEC to identify differences in combinatorial language acquisition between ASD (N=29138) and neurotypical (N=111) children. Results confirm the utility of the MSEC in distinguishing language deficits in ASD from typical development as early as 2 years of age (p<0.0001).

2021). However, recent research has shown that environmental factors can increase the likelihood of autism's development and exacerbate its symptoms (Chaste & Leboyer, 2012;Ratajczak, 2011).One environmental factor that affects all children's development is diet (Whiteley et al., 2013). Autistic children have been shown to be especially susceptible to imbalances and abnormalities in gastrointestinal function (Adams et al., 2018;Peretti et al., 2019). Imbalances in gut function heavily influence the central nervous system through the brain-gut axis, and dysfunction of this broad neural circuitry can significantly impact the development of the higherorder cognitive functions that autistic children struggle with (Carabotti et al., 2015;Jones et al., 2022). Thus, many recent studies have attempted to elucidate the correlation between autistic children's behaviors and their diet (Adams
