The effects of ritual and self-control resources depletion on deceptive behavior: Evidence from behavioral and ERPs...

Although researchers have indicated that individuals with depleted self-control resources have lower self-control behavior and exhibit more deceptive behaviors, recent psychological studies have shown that ritual can improve self-control and increase the likelihood that the individual makes prosocial decisions. However, little is known about whether ritual can regulate an individual's engagement in deceptive behavior when their self-control resources are depleted. This study adopted the spot-the-difference task to investigate the influences of ritual and self-control resources depletion on simple self-control behavior and deceptive behavior (Experiment 1 and Experiment 2); furthermore, relevant neural processes were explored using event-related potentials (Experiment 3). Experiment 1 showed that individuals with depleted self-control resources had lower self-control behavior and individuals performing a ritual had higher self-control behavior. Experiment 2 showed that individuals with depleted self-control resources exhibited more deceptive behaviors and individuals performing a ritual exhibited fewer deceptive behaviors; furthermore, ritual reduced deceptive behaviors in individuals with depleted self-control resources. Experiment 3 found that individuals with depleted self-control resources had larger P2 amplitudes after performing a ritual. Moreover, individuals with depleted self-control resources had larger LPP amplitudes over parietal sites after performing a ritual. These findings suggested that performing ritual may be an effective measure of inhibiting individuals with depleted self-control resources from engaging in deceptive behavior. Our findings verify the ego-depletion model and provide a new perspective for reducing deceptive behaviors in individuals with depleted self-control resources. We provide evidence that rituals could modulate deceptive behaviors in individuals with depleted self-control resources. This reveals that performing rituals may be an effective measure for inhibiting individuals with depleted self-control resources from engaging in deceptive behavior.
