Heuristics used in human decision-making are usually instinctually determined and can result in cognitive bias. People with developmental disorders are known to be particularly vulnerable to such cognitive biases. However, the relationship between these biases and developmental disorders in children has not yet been sufficiently established. Here, we created scenario tests with cognitive bias designed for children and sought to clarify the relationship between cognitive bias and autistic traits in children. Biased scenario tests designed for children were created and 25 6th graders (standard classes only) were asked to respond to scenario questions. We then examined the relationship between their responses and the Autism-Spectrum Quotient (AQ). Results showed that there was a relationship between specific cognitive biases and autistic traits. Specifically, total number of correct responses on the biased scenario test and severity of communication skill impairment were negatively correlated in both males and females, total number of correct responses on the biased scenario test and severity of social skill impairment were negatively correlated in males, and total number of correct responses cognitive reflection and imagination were positively correlated in females. These results show that autistic traits can be quantitatively evaluated using the cognitive bias scenarios we created.
