Infants at increased likelihood for autism spectrum disorder (ASD) exhibit more negative affect and avoidance behaviour than typically developing infants, and children with ASD express fear differently than typically developing peers. We examined behavioural reactions to emotion-evoking stimuli in infants at increased familial likelihood for ASD. Participants included 55 increased likelihood (IL) infants (i.

Research concerning temperament in children and adults with autism spectrum disorder (ASD) has suggested a consistent profile of low positive affect, high negative affect, and low regulation (Visser et al., 2016). One area receiving less attention is individual differences among children diagnosed with ASD.

Autism spectrum disorder (ASD) represents a group of neurodevelopmental disabilities that can be difficult to identify before the age of 2 or 3 years, the age when the full range of behavioral symptoms has emerged in most cases. Initiation of joint attention is an important developmental function in which impairments are already observable before the second birthday and can predict children's ASD symptomatology. In the first part of this review, we summarize results pertaining to retrospective studies of initiation of joint attention in children with ASD and prospective studies of infants at high risk for ASD during the first 2 years, when this behavior is becoming more complex in terms of frequency, quality, and variety.

Impairments in visual disengagement are a current focus of research in autism spectrum disorders (ASD) and may play a key role in the early expression of social-emotional deficits associated with the disorder. This review summarizes current knowledge of visual disengagement and orienting in ASD. Convergent reports from infancy to adulthood indicate that (1) impairments to visual disengagement are apparent on Gap-Overlap tasks, spatial orienting tasks, and tasks involving social stimuli; and (2) these impairments emerge in the first year of life and continue into adulthood.

As part of a major collaborative research initiative, Advancing Interdisciplinary Research in Singing (AIRS), we developed a protocol for obtaining audiovisual information reflecting aspects of the ability to sing. We also developed a digital library prototype, the Children's International Media Exchange for Singing (CHIMES), to index and store the data for access through the Internet by researchers worldwide. The protocol was piloted at five monthly intervals with 20 individuals (children 3, 5, and 7 years of age and adults differing in vocal training level), validating its feasibility in Western culture and producing rich data amenable to numerous levels and kinds of analysis.
