项目摘要

There are numerous indications that pornography consumption has reached a new dimension due to easy access via the internet. While most men report no problems concerning their VSS-consumption, some experience a loss of control in the course of their consumption history. Despite seriously negative consequences (e.g., occupational and relationship problems, depression), these men seem to be unable to achieve a lasting reduction of their VSS-consumption. Some researchers interpret these symptoms in terms of a behavioral addiction. Results from drug addiction research point to an association between stress and augmented addiction behavior as well as relapses, potentially mediated by an interaction between the stress hormone cortisol and the dopaminergic reward system. Habitual VSS-consumption (VSS-consumption-intensity) considerably differs between men. It is widely unknown which personality traits are predictive for VSS-consumption-intensity and whether increasing VSS-consumption-intensity is associated with altered VSS-processing. Altered VSS-processing would be expected given the the well-established neurobiological incentive-sensitization theory of addiction by Robinson and Berridge (1993). To date, studies investigating the impact of stress and VSS-consumption-intensity on VSS-processing are rare and have so far revealed inconsistent results.For the proposed research project, it is planned to investigate the impact of (1) stress, (2) individual VSS-consumption-intensities and (3) the stress x VSS-consumption-intensity interaction on VSS-processing in men. In a between subject design, half of the participants will undergo a stress test, which reliably results in cortisol release. The other half will pass a control condition without an expected cortisol release. Both groups consist of four subgroups with different (very low, low, high, very high) VSS-consumption-intensities. In the planned experiment, VSS-anticipation and VSS-consumption phases will alternate. For the different phases, a different impact of stress and VSS-consumption-intensity is expected. Beside fMRI data, humoral, morphometric, connectivity, peripher-physiological, behavioral, and subjective data will be collected. Further, personality traits, VSS consumption motives as well as psychopathological symptoms will be assessed by questionnaires. These data offer a remarkable data basis for mediator and moderator analyses concerning the impact of stress and VSS-consumption-intensity on VSS-processing. This will result in testable hypotheses of critical factors involved in the development of excessive and out-of-control consumption behavior with regard to VSS.

有许多迹象表明，由于通过互联网很容易获得，色情消费已经达到了一个新的层面。虽然大多数男性报告他们的VSS消费没有问题，但有些人在消费过程中失去了控制。尽管有严重的负面后果（例如，职业和关系问题，抑郁症），这些人似乎无法实现他们的VSS消费的持久减少。一些研究人员将这些症状解释为行为成瘾。药物成瘾研究的结果指出，压力和成瘾行为以及复发之间存在关联，可能是由压力激素皮质醇和多巴胺能奖励系统之间的相互作用介导的。习惯性VSS消费（VSS消费强度）在男子之间有很大差异。目前还不清楚哪些人格特质可以预测VSS消费强度，以及VSS消费强度的增加是否与VSS处理的改变有关。考虑到罗宾逊和贝里奇（1993）完善的成瘾神经生物学激励-致敏理论，VSS处理的改变是预料之中的。目前，关于压力和VSS-消耗-强度对VSS-加工的影响的研究很少，且结果不一致。本研究计划调查（1）压力、（2）个体VSS-消耗-强度和（3）压力× VSS-消耗-强度交互作用对男性VSS-加工的影响。在受试者之间的设计中，一半的参与者将接受压力测试，这可靠地导致皮质醇释放。另一半则会通过控制条件，而不会释放预期的皮质醇。两组均由具有不同（非常低、低、高、非常高）VSS消耗强度的四个亚组组成。在计划的实验中，VSS预测和VSS消费阶段将交替进行。对于不同的阶段，压力和VSS消耗强度的影响是不同的。除了功能磁共振成像数据，体液，形态测量，连接，外周生理，行为和主观数据将被收集。此外，人格特质，VSS消费动机以及精神病理症状将通过问卷调查进行评估。这些数据提供了一个显着的数据基础，中介和调节分析压力和VSS消费强度对VSS加工的影响。这将导致可检验的假设的关键因素参与发展过度和失控的消费行为方面的VSS。
