Infant Sibling Study: Attention and Emotional Regulation in Typical Development and Autism Spectrum Disorder

Characterizing Autism


Azadeh Kushki, PhDJessica Brian, PhD

Participate in this study

We are trying to determine whether early behavioural signs of Autism Spectrum Disorder (ASD) can be observed in young infants. Second we hope to learn more about whether differences in certain body signals (such as temperature, heart rate, sweating) during a variety of tasks can be observed. We want to see if these signs are different in infants who go on to have ASD, compared to those who do not.

Who can participate

Younger siblings (6-12 months of age) who have an older sibling with ASD OR younger siblings (6-12 months of age) who have an older sibling whose families do not have a history of ASD.

What's Involved


  • We will use tests that look at the symptoms of autism, tests that look at the way that your child thinks and behaves, and activities that look at the way your child reacts.
  • Your child will be seen for their first visit at 6 or 12 months based on their age at recruitment.
  • Your child will be followed in 6 month intervals between 6 months and 24 months then at 36 months.
  • Parent interviews and questionnaires will also be completed at these time points.

Benefits of participating include:

  • Ongoing feedback about your child's development.
  • Opportunities to ask questions about your child's development.
  • Contribute to our understanding of autism.


Recruitment for this research project ended in January 2020.
