The purpose of this study is to identify the best model that explains the relationship between conflicting risk structures and decision quality. Using confirmatory factor analysis and hierarchical regression techniques as statistical methods, the author confirmed that changes in the conflicting risk structures correlated with changes in decision…

The present study explored the dimensionality of cognitive structure from two approaches. The first approach used a famous relation between Visual Spatial Working Memory (VSWM) and calculation to demonstrate the multidimensional item response analyses when true dimensions are unknown. The second approach explored the detectability of dimensions by…
