Failure generates impulsivity only when outcomes cannot be controlled

Verbruggen, Chambers, Lawrence & McLaren (2017) recently challenged the view that individuals act with greater caution following the experience of a negative outcome by showing that a gambled loss resulted in faster reaction time on the next trial. Over three experiments, we replicate and establish the boundary conditions of this effect in the context of a simple game (Rock, Paper, Scissors). Choice responding against unexploitable opponents replicated the link between failure and faster responding. However, individuals with high win-rates against exploitable opponents initiated slower rather than faster responding following loss. The data suggest that the link between failure and impulsivity is limited to contexts where participants cannot exert control over outcomes
