Effect of swearing on strength: Disinhibition as a potential mediator [PDF]

open access: yesQuarterly Journal of Experimental Psychology, 2021
Swearing fulfils positive functions, including benefitting pain relief and physical strength. Here we present two experiments assessing a possible psychological mechanism, increased state disinhibition, for the effect of swearing on physical strength. Two repeated measures experiments were carried out with sample sizes N = 56 and N = 118. Both included
