A love that doesn’t last: Pornography consumption and weakened commitment to one’s romantic partner
Nathaniel M Lambert et al.; 2012
We examined whether the consumption of pornography affects romantic relationships, with the expectation that higher levels of pornography consumption would correspond to weakened commitment in young adult romantic relationships. Study 1 (n = 367) found that higher pornography consumption was related to lower commitment, and Study 2 (n = 34) replicated this finding using observational data. Study 3 (n = 20) participants were randomly assigned to either refrain from viewing pornography or to a self-control task. Those who continued using pornography reported lower levels of commitment than control participants. In Study 4 (n = 67), participants consuming higher levels of pornography flirted more with an extradyadic partner during an online chat. Study 5 (n = 240) found that pornography consumption was positively related to infidelity and this association was mediated by commitment. Overall, a consistent pattern of results was found using a variety of approaches including cross-sectional (Study 1), observational (Study 2), experimental (Study 3), and behavioral (Studies 4 and 5) data.
