Too Dog Tired to Avoid Danger: Like Humans, Dogs Engage in Riskier Behaviors When Their Self-Control Is Depleted

ScienceDaily (Apr. 2, 2012) — Like humans, dogs engage in riskier behaviors when their self-control is depleted.


How do dogs behave when their ability to exert self-control is compromised? Are they more likely to approach dangerous situations or stay well away? According to a new study by Holly Miller, from the University of Lille Nord de France, and colleagues, dogs that have 'run out' of self-control make more impulsive decisions that put them in harm's way. The work was just published online in Springer'sPsychonomic Bulletin & Review.



To avoid danger, people often exert self-control over their behavior. When they do not and they behave more impulsively, they may unintentionally put themselves in dangerous situations e.g. pedestrians jaywalk across busy streets, children stick objects into electrical outlets, and teenagers join dangerous gangs. Miller and colleagues' work is the first to demonstrate that this phenomenon of 'self-control depletion' also has significant behavioral implications in animals: mentally fatigued dogs do not think straight and are more likely to inadvertently subject themselves to risks that may result in physical harm.
