The article provides a review of current dominant view on impulsivity which distinguishes personality and behavioral models. In the context of personality models, impulsivity is measured by self-report questionnaires. Behavioral models further divide impulsivity into impulsive action and impulsive choice. Both impulsivity subtypes are measured by different behavioral tests. The present article focuses in detail on the most frequently used tests in the individual categories (Barratt Scale, UPPS-P Scale, Go/NoGo Task, Stop Signal Task and Delay Discounting Task) and on selected methodological aspects of impulsivity measuring which can contribute to heterogeneous results in the current literature (especially high test parameters variability and the lack of studies comparing different tests in different populations). The review also discuss-es the relations between different impulsivity dimensions and specific impulsivity types, such as emotional impulsivity or impulsivity targeted on specific stimuli (e.g. food or alcohol). The existence of such impulsivity subtypes can explain why impulsivity tests sometimes won't detect impulsivity in people who clearly suffer from poor self-control. The article suggests future directions of impulsivity research with emphasis on specific impulsivity types detection and risky behaviour prediction.
