Who am I? - Development and Analysis of an Interactive 3D Game for Psychometric Testing

Abstract

Psychometric testing has become a popular scientific method to measure individuals’ mental capabilities and behavioural styles. Traditional psychometric tests are standardised and usually require the completion of paper forms. This means they are tedious to complete, can cause anxiety, and it is obvious to participants that a psychometric test is being conducted, potentially affecting how questions are answered. We develop and analyse an interactive 3D game which measures similar metrics to a psychometric test, but is unobtrusive and fun to complete. Specifically developed game elements are used to measure three psychometric properties related to motivation: extraversion, neuroticism and conscientiousness. A user study with 30 participants revealed that the game provided a valid measure for neuroticism when compared with traditional assessments, but was less successful for other traits. Participants were accepting a longer playtime compared to traditional tests, and most were unaware they completed a personality test.
