| Outline of Final Research Achievements |
The Implicit Association Test (IAT) is a computer-based psychological experiment and is now widely used in a variety of fields of psychology as an effective measure of a person’s implicit attitudes. However, it has been pointed out several factors unrelated to implicit attitudes, the tentative condition of body and mind, strategic effects and so on, considerably affect the IAT results. In order to assess individual differences, decomposing of the IAT effect into the indicators of implicit attitudes and other confounding factors is very important.
In this study, we have proposed to analyze the IAT data based on the Ratcliff’s diffusion model and have shown the possibility that the diffusion model analysis provides a theory-based tools to filter out IAT effects from confound factors. In addition, we have developed a user-friendly software in order to facilitate the application of diffusion model analyses, based on fast-dm-30 by Jochen Voss and Andreas Voss.
