Deontic norms are expected to impose individuals’ control over their behavior. In this paper, we address such norms presented in trafc signs and test their infuence over executive control functions. For Experiment 1, we develop a trafc fanker task in which the typical neutral arrows are replaced with trafc prohibition/obligation signs. Experiment 2 isolated the deontic aspect of the signs using simple arrows on red, blue, and green backgrounds and either primed them to be interpreted as trafc signs or as elements of a gaming console controller. Results in both studies show evidence of controlling context interferences more efciently when dealing with deontic (trafc) signs than with simple arrows (Experiment 1) or with similar perceptive targets when primed with a deontic context than with a gaming context (Experiment 2). In both studies, obligation/blue signs mitigate fanker efects less than prohibition/red signs. Stimuli color afects the alertness of the cognitive system, with the color red being, by itself, a cue for increased control. Based on temporal analysis, we further discuss these results as evidence of an increase in proactive control that aims to prevent the occurrence of undesirable infuence.
