“The current research examines the effect of self-regulation on the likelihood of committing infidelity.
Thirty-two college students in exclusive romantic relationships interacted through a private chat room with an opposite-sex confederate. Prior to this interaction, a food-restriction task depleted half the participants of self-control.
As predicted, depleted levels of self-regulation increased the likelihood of infidelity.
Specifically, depleted participants were more likely to both accept a coffee date from and supply a personal telephone number to the confederate than non-depleted participants.
Weakened self-control may be one potential cause for the levels of infidelity occurring in romantic partnerships today.”
This is the abstract of the original study here (2009)
