Do Varying Levels of Exposure to Pornography and Violence Have an Effect on Non-Conscious Emotion in Men (2020)
Comments: Ignoring Prause et al.’s unsupported title, the authors accepted the most likely explanation mentioned in Prause et al., 2015:
“Prause et al. suggested that this unexpected finding may be due to habituation effects, as the participants who presented with the reduced LPP waveform also scored significantly higher in the amount of hours they spent viewing pornographic material.”
Habituation, not ‘falsification”.
Excerpt mentioning Prause et al., 2015:
Studies investigating neural attributes to problematic or frequent pornographic material use are relatively scarce. Unproblematic or infrequent use of pornographic material generally induces an enhanced LPP waveform when individuals are presented with erotic visual information (Prause et al., 2015). A larger amplitude LPP is an index of sustained processing of emotionally relevant stimuli and is a marker of motivational significance (Voon et al., 2014). In contrast, with regard to ERP effects of problem viewing of visual sexual stimuli, existing literature has generally shown a reduced amplitude LPP component. Prause et al. presented individuals who either reported or denied problematic pornography use with emotion-inducing images (including explicit sexual images). Individuals who reported problems policing their pornography use and who had a stronger desire for sex demonstrated lower LPP amplitudes in response to the explicit sexual images. Prause et al. suggested that this result was unexpected. Numerous studies of individuals with addictive behaviors have employed cuerelated emotional tasks. Typically, these studies have found an increased LPP amplitude when presented with images of the individual’s addiction-inducing substance (Minnix et al., 2013). Prause et al. suggested that this unexpected finding may be due to habituation effects, as the participants who presented with the reduced LPP waveform also scored significantly higher in the amount of hours they spent viewing pornographic material.
