Eye Gaze in Autism Spectrum Disorder: A Review of Neural Evidence for the Eye Avoidance Hypothesis

Reduced eye contact early in life may play a role in the developmental pathways that culminate in a diagnosis of autism spectrum disorder. However, there are contradictory theories regarding the neural mechanisms involved. According to the amygdala theory of autism, reduced eye contact results from a hypoactive amygdala that fails to flag eyes as salient. However, the eye avoidance hypothesis proposes the opposite-that amygdala hyperactivity causes eye avoidance. This review evaluated studies that measured the relationship between eye gaze and activity in the 'social brain' when viewing facial stimuli.

The valence-specific empathy imbalance hypothesis of autism: The role of autistic traits, alexithymia, emotion dysregulation, and gender differences

Individuals exhibiting pronounced autistic traits (e.g., social differences and specialised interests) may struggle with cognitive empathy (i.e., the ability to infer others' emotions), although the relationship with affective empathy (i.e., the ability to share others' emotions) is less clear in that higher levels of autistic traits may be linked with increased affective empathy for negative emotions but reduced affective empathy for positive emotions. The current study investigates this empathy profile and whether alexithymia and emotion dysregulation help to explain it.

Caregiver-Mediated Early Support Program Delivered Online Versus Care-as-Usual for Infants at Elevated Familial Likelihood for Autism

LiL' STEPS (Language development & Intervention Lab's SupporTing Early social-communication and language by Promoting caregiver Sensitive responsiveness) is a novel, manualized, caregiver-mediated early support program developed in India and delivered online for infants at elevated familial likelihood for autism. The program has been found to be feasible and acceptable. The preliminary efficacy of the LiL' STEPS program, which remains to be evaluated, was assessed in this study using a feasibility randomized controlled trial design. 

Utilising Behavioural and Sensory Profiles and Associated Perinatal Factors to Identify Meaningful Subgroups in Autism Spectrum Disorder

The heterogeneity of autism spectrum disorder clinically and aetiologically hinders intervention matching and prediction of outcomes. This study investigated if the behavioural, sensory, and perinatal factor profiles of autistic children could be used to identify distinct subgroups. Participants on the autism spectrum aged 2 to 17 years and their families were sourced via the Australian Autism Biobank.

Autistic and autism community perspectives on infant and family support in the first two years of life: Findings from a community consultation survey

Most support programmes for Autistic children are available only after they are diagnosed. Research suggests that parenting supports may be helpful for parents and their infants, when provided in the first 2 years of life - before a formal diagnosis is given, but when information suggests an infant is more likely to be Autistic. However, we do not know how acceptable these types of supports might be to the Autistic and autism communities.

Which emerging autism features at 12 months of age are associated with later parent-child interaction?

Parent-child interactions (PCI) in infants with an elevated likelihood (EL) of autism start to diverge from other infants toward the end of the first year. This divergence is often attributed to emerging features of autism impacting infant social interactions in ways that become increasingly amplified. The aim was to identify which, if any, 12-month autism features were associated with later PCI qualities.

Influences of bilingual input on English vocabulary size and academic outcomes: a large-scale longitudinal study following children in Australia from five to ten years

Research from large population-based studies investigating the language and academic outcomes for bilingual children is rare. The current study aimed to investigate the influence of dual language exposure on (i) English vocabulary outcomes at 5 years (126 bilinguals, 1675 monolinguals), and 10 years (vocabulary: 92 bilinguals, 1413 monolinguals:), and (ii) academic outcomes at 10 years (107 bilinguals, 1746 monolinguals).

Developmental vitamin D deficiency increases foetal exposure to testosterone

Autism spectrum disorder (ASD) is a group of neurodevelopmental disorders which are more common in males. The 'prenatal sex steroid' hypothesis links excessive sex-steroid exposure during foetal life with the behavioural differences observed in ASD. However, the reason why sex steroid exposure may be excessive remains unclear. Epidemiological studies have identified several environmental risk factors associated with ASD, including developmental vitamin D (DVD) deficiency.

LIFECYCLE - Early Life Stressors and LifeCycle Health

LIFECYCLE is a significant and visionary project to establish an integrated set of long-term world-wide cohorts and clinical trials, which can be investigated and compared across the full life of cohort participants.
