Neuropsychopharmacology - Abstract of article: Can Pornography be Addictive[quest] An fMRI Study of Men Seeking Treatment for Problematic Pornography Use

    Pornography consumption is highly prevalent, particularly among young adult males. For some individuals, problematic pornography use (PPU) is a reason for seeking treatment. Despite the pervasiveness of pornography, PPU appears under-investigated, including with respect to the underlying neural mechanisms.

    Using functional magnetic resonance imaging (fMRI), we examined ventral striatal responses to erotic and monetary stimuli, disentangling cue-related 'wanting' from reward-related 'liking' among 28 heterosexual males seeking treatment for PPU and 24 heterosexual males without PPU.

    Subjects engaged in an incentive delay task in the scanner, in which they received erotic or monetary rewards preceded by predictive cues. BOLD responses to erotic and monetary cues were analyzed and examined with respect to self-reported data on sexual activity collected over the 2 preceding months.

    Men with and without PPU differed in their striatal responses to cues predicting erotic pictures, but not in their responses to erotic pictures. PPU subjects when compared to control subjects showed increased activation of ventral striatum specifically for cues predicting erotic pictures but not for cues predicting monetary gains.

    Relative sensitivity to cues predicting erotic pictures versus monetary gains was significantly related to the increased behavioral motivation to view erotic images (suggestive of higher 'wanting'), severity of PPU, amount of pornography use per week and number of weekly masturbations.

    Our findings suggest that, similar to what is observed in substance and gambling addictions, the neural and behavioral mechanisms associated with the anticipatory processing of cues specifically predicting erotic rewards relate importantly to clinically relevant features of PPU.

    These findings suggest that PPU may represent a behavioral addiction and that interventions helpful in targeting behavioral and substance addictions warrant consideration for adaptation and use in helping men with PPU.

    Pornography Consumption, Modality and Function in a Large Internet Sample

    Pornography consumption research often contains measurement inconsistencies that make the literature difficult to integrate.

    We investigated measurement issues relating to four key areas of pornography research simultaneously in a single data set:

    (a) differential endorsement across commonly used pornography consumption measures;

    (b) common modalities of pornography use (e.g., pictures, videos);

    (c) function of pornography use; and

    (d) association of age and gender with the above.

    The sample (n = 1,392) of adults in the United States was collected using Amazon Mechanical Turk and included a much wider age range (ages 18-73) than in typical pornography research.

    Using all modalities of pornography, 91.5% of men and 60.2% of women herein reported having consumed pornography in the past month.

    The three primary modalities of pornography consumed were
    · written pornography,
    · pictures, and
    · videos.

    Videos were consumed most often, but women were much more likely to consume written pornography than men. The primary function of viewing pornography was to enhance masturbation, but notably there was endorsement of many other uses.

    Cross-sectional age trends and gender differences are discussed with suggestions for future research. Empirical concerns for research in pornography are addressed, with special attention to considerations for estimates of pornography consumption rates and research definitions of pornography.

    Written pornography? That’s almost an oxymoron
