Infants' reorienting efficiency depends on parental autistic traits and predicts future socio-communicative behaviors.

Researchers studied how well 8-month-old babies could shift their attention from one thing to another, and found this related to their parents' autism-like traits. Babies whose parents had more autism-like characteristics showed slower attention shifting. When these babies were tested again at 21 months old, those with slower attention shifting as infants had more difficulties with social communication skills. This suggests attention problems might be an early sign that could predict later social challenges.

This longitudinal study examined attentional reorienting in 8-month-old infants whose parents had varying levels of autistic traits. The research followed 71 infants, categorizing them into high parental traits (n=23) and low parental traits (n=48) groups based on parent self-reports. Using an attentional cueing task measuring saccadic latencies, researchers found that infants with sluggish reorienting systems showed this pattern predicted poorer socio-communicative behaviors when assessed at 21 months. The study suggests that early stimulus-driven attention difficulties may be transgenerationally influenced and could represent a causal pathway to later social-communication challenges, supporting the research domain criteria framework for understanding autism development.

Early attentional reorienting assessment at 8 months may serve as a potential screening tool for identifying infants at risk for future socio-communicative difficulties. Findings suggest attention-based early interventions might be beneficial, particularly for families with higher parental autistic traits.

Study does not specify methodology details or statistical analyses in the abstract. Sample size reduction from 89 to 71 participants suggests potential attrition issues. Limited information about measurement tools and outcome assessments. Causal relationships implied but not definitively established through study design.

Attentional reorienting is dysfunctional not only in children with autism spectrum disorder (ASD), but also in infants who will develop ASD, thus constituting a potential causal factor of future social interaction and communication abilities. Following the research domain criteria framework, we hypothesized that the presence of subclinical autistic traits in parents should lead to atypical infants' attentional reorienting, which in turn should impact on their future socio-communication behavior in toddlerhood. During an attentional cueing task, we measured the saccadic latencies in a large sample (total enrolled n = 89; final sample n = 71) of 8-month-old infants from the general population as a proxy for their stimulus-driven attention. Infants were grouped in a high parental traits (HPT; n = 23) or in a low parental traits (LPT; n = 48) group, according to the degree of autistic traits self-reported by their parents.

Infants (n = 33) were then longitudinally followed to test their socio-communicative behaviors at 21 months. Results show a sluggish reorienting system, which was a longitudinal predictor of future socio-communicative skills at 21 months. Our combined transgenerational and longitudinal findings suggest that the early functionality of the stimulus-driven attentional network-redirecting attention from one event to another-could be directly connected to future social and communication development.
