| Outline of Research at the Start |
This study aimed to fill the gap in crossmodal correspondence study by exploring the factors constructing CSAs with examining individuals with developmental disorders, sensory deprivation, and different personality traits. It will be helpful to understand the mechanism in crossmodal correspondence

| Outline of Final Research Achievements |
The present study used both explicit and implicit experimental methods to examine color-shape associations in developmental disorders. By the online questionnaire survey, participants with higher autistic traits showed fewer consensual color-shape associations. However, using computer-based indirect experimental method, participants with higher autistic traits showed stronger congruency effect of CSAs on both feature discrimination and feature binding (e.g., circle-red, triangle-yellow) tested by IATs and illusory conjunction task. Thus, autistic traits play a role in the construction of color-shape associations. Those results may be explained by the Bayesian model underlying autistic perception. People may construct color-shape associations 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.

| Academic Significance and Societal Importance of the Research Achievements |
People with higher autistic traits showed a stronger binding of color-shape associations. Autistic traits play a role in the construction of color-shape associations. Those results shed light on the nature of color-shape associations and autistic perception, which could be used in visual design.
