Outline of Annual Research Achievements

This study using explicit and implicit experimental methods examined color-shape associations(CSAs) in developmental disorders.
I found that participants with higher autistic traits showed stronger congruency effect of CSAs on both response based feature discrimination and feature binding (e.g., circle-red, triangle-yellow) tested by IATs and binding errors. Thus, people with higher autistic traits have stronger CSAs, and autistic traits play a role in the construction of CSAs.
Those results may be explained by the Bayesian model underlying autistic perception. People may construct CSAs at an early age, and the strength of those associations have been weakened by learning with co-occurrence of colors and shapes in the environment, while people with higher autistic traits may influenced less by prior learning experience.
