Our research focuses on identifying causal mechanisms that lead to the differential development of social attention in individuals with autism spectrum disorder (ASD) as well as the cascading effects of social attentional impairments, especially joint attention (JA), on various domains of functioning. We employ a range of methodologies, including eye tracking, large, shared data sets, and behavioral coding to examine JA and other social attention behaviors.
Ongoing research interests include:
- Applying information-processing theories of attentional impairment typically used to explain mood and anxiety disorders to examine the function and origin of attention biases in ASD.
- Using eye-tracking technology to:
- measure and increase the understanding of the development of JA.
- evaluate the effectiveness of interventions designed to enhance social attention among individuals in ASD.
- investigate critical points in development when children with autism demonstrate divergent social attention.
- Assessing how distinct social attention behaviors may relate to one another.

Cross Cultural & Global ASD Research
Our lab examines factors contributing to disparities in ASD services, such as ASD knowledge.
Current interests in this area include:
- Assessing ASD knowledge or stigmas of ASD:
- Developing a new measure of ASD knowledge entitled, the Autism Stigma & Knowledge Questionnaire (ASK-Q).
- Continuing to norm and assess the psychometric properties of the ASK-Q.
- Examining the cross-cultural utility of the ASK-Q.
- Assessing ASD knowledge or stigmas of ASD in low- and middle-income countries such as Tanzania.
- Examining factors, such as limited knowledge, that may contribute to an underutilization of Early Intervention services in local schools.
- Developing and implementing ASD knowledge interventions
- Implementing interventions among non-English-speaking parents and teachers to help increase knowledge of behavior modification strategies that can be used to improve child functional outcomes using verbal didactics, pictorial handouts, interpreters, and strategy modeling. Assessing the efficacy of these interventions using the ASK-Q.
- Developing individual and community intervention approaches to address low ASD knowledge and stigmas in low-income countries.
- Evaluating teacher and parent psychoeducational interventions conducted in Tanzania and other countries.
