Development and Validation of a New Risk-Taking Game: Helsinki Aiming Task (HAT)
Ilmari Määttänen, Jussi Palomäki, Juha Vepsäläinen, Emilia Makkonen

TL;DR
The Helsinki Aiming Task (HAT) is a new game that measures risk-taking behavior and how people respond to rewards and punishments.
Contribution
HAT introduces a novel method to assess risk-taking with fine-grained behavioral responses to penalties and rewards.
Findings
Participants became more cautious with higher penalties and gun inaccuracy.
HAT reward and punishment sensitivity was linked to personality traits and self-reported risk-taking.
HAT indicators explained self-reported risk better than BART.
Abstract
We introduce and describe a new risk-taking game, Helsinki Aiming Task (HAT), and test its construct (internal) and convergent (external) validity. HAT is a shooting game, in which the participants aim at a target under varying levels of “gun” inaccuracy and penalty for missing the target. It allows fine-grained examination of risk-taking behaviour, as it contains information on the effects of penalties and rewards on single, isolated decisions, immediately after each isolated event outcome. We validate HAT by studying individual responses to changing penalty levels and the accuracy of the “gun”, and by comparing it to behavioural and self-reported risk measures, personality traits, and socioeconomic variables. In study one (n = 51), we evaluated risk-taking responses (measured by aiming point) and their relation to other task variables (such as penalty levels and “gun” inaccuracy). In…
