Infants' ability to discriminate between auditory stimuli presented in rapid succession and differing in fundamental frequency (Rapid Auditory Processing [RAP] abilities) has been shown to be anomalous in infants at familial risk for Language Learning Impairment (LLI) and to predict later language outcomes. This study represents the first attempt to investigate RAP in Italian infants at risk for LLI (FH+), examining two critical acoustic features: frequency and duration, both embedded in a rapidly-presented acoustic environment. RAP skills of 24 FH+ and 32 control (FH-) Italian 6-month-old infants were characterized via EEG/ERP using a multi-feature oddball paradigm. Outcome measures of expressive vocabulary were collected at 20 months. Group differences favoring FH- infants were identified: in FH+ infants, the latency of the N2* peak was delayed and the mean amplitude of the positive mismatch response was reduced, primarily for frequency discrimination and within the right hemisphere. Moreover, both EEG measures were correlated with language scores at 20 months. Results indicate that RAP abilities are atypical in Italian infants with a first-degree relative affected by LLI and that this impacts later linguistic skills. These findings provide a compelling cross-linguistic comparison with previous research on American infants, supporting the biological unity hypothesis of LLI.

This study examined the impact of the coronavirus disease 2019 (COVID-19) pandemic in Italy by specifically looking at the psychosocial response of children/adolescents with neurodevelopmental disabilities (NDD) and their parents, and explored which factors could potentially contribute to increasing or mitigating stress-related behaviors in children/adolescents as well as their parents' stress. An online anonymous survey was designed to investigate family demographic characteristics, COVID-19 outbreak and restriction-related variables, children/adolescents' behavioral regulation problems, parental stress, and resilience. Data were collected from 1,472 parents (83.1% mothers) of 1632 NDD children/adolescents (33.7% females). Compared to pre-emergency, parents reported a significant increase in their children's behavioral regulation problems: Anxious/depressed behavior, Attention problems, and Aggressive behavior (p < .001), and they reported feeling more Overwhelmed and Burdened (p < .001) as parents but less Unfulfilled, Numbness, Devastated, and Angry (p < .001). A hierarchical stepwise regression analysis revealed that both behavioral regulation problems in NDD children/adolescents and parental stress are-at least partially-buffered by resilience factors in parents (Perception of self, Planned future, Family cohesion). Results showed that behavioral regulation problems in children/adolescents with NDD and parental stress increased. However, parental resilience can act as a protective factor, counterbalancing parental difficulties in the care of their NDD children during the emergency. Identifying risk and protective factors impacting the psychosocial response ofchildren/adolescents with NDD and their parents is essential to implement appropriate support interventions both for parents and children/adolescents with NDD during the COVID-19 pandemic.

Previous research found that the parental autism phenotype is associated with child autism spectrum disorder (ASD), even if the pathway between autistic traits in parents and child ASD is still largely unknown. Several studies investigated frontal asymmetry in alpha oscillation (FAA) as an early marker for ASD. However, no study has examined the mediational effect of FAA between parental autistic traits and child ASD symptoms in the general population. We carried out a prospective study of 103 typically developing infants and measured FAA as a mediator between both maternal and paternal autistic traits and child ASD traits. We recorded infant baseline electroencephalogram (EEG) at 6 months of age. Child ASD symptoms were measured at age 24 months by the Child Behavior Checklist 1½–5 Pervasive Developmental Problems Scale, and parental autistic traits were scored by the Autism spectrum Quotient questionnaire. The mediation model showed that paternal vs. maternal autistic traits are associated with greater left FAA which, in turn, is associated with more child ASD traits with a significant indirect effect only in female infants vs. male infants. Our findings show a potential cascade of effects whereby paternal autistic traits drive EEG markers contributing to ASD risk.
