The Dickman Impulsivity Inventory (DII), developed by Dickman (1990), revealed that impulsivity can be distinguished between Functional and Dysfunctional Impulsivity (FI and DI); FI being an optimal tendency to act with relatively little forethought, and DI being a non-optimal tendency to act with less forethought. A Japanese version of the DII was developed through surveying 1080 women for an exploratory factor analysis, and 234 undergraduate students (123 women, 111 men) for a confirmatory factor analysis. Results revealed three factors: Functional Impulsivity; Dysfunctional Impulsivity; and Discretion. These tendencies were then correlated with performance of a cognitive task in which two geometrical figures were presented side by side, and participants were required to judge whether these figures were different as quickly as possible. Results showed that FI, but not DI, positively correlated with the number of responses and the number of correct responses.
