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，由于通过互联网轻松访问，色情消费已经达到了新的维度。虽然大多数男性在消费历史的过程中都会遇到有关VSS消费的问题，但有些人在消费历史上遭受了失去控制权。尽管严重的负面后果（例如，职业和关系问题，抑郁症），这些人似乎无法实现其VSS消费的持久减少。一些研究人员用行为成瘾来解释这些症状。药物成瘾研究的结果表明，压力与增强成瘾行为之间的关联以及复发，可能是由压力激素皮质醇与多巴胺能奖励系统之间的相互作用介导的。男性之间的习惯性与消费（VSS消费强度）有很大不同。哪些人格特征可预测VSS征服强度以及增加VSS消耗强度是否与VSS处理的改变有关，这是未知的。鉴于Robinson and Berridge（1993）的成瘾良好的神经生物学激励理论，将有望改变VSS加工。 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.在主题设计之间，一半的参与者将接受压力测试，这可靠地导致皮质醇释放。另一半将通过控制条件，而没有预期的皮质醇释放。这两组由四个亚组组成，具有不同的（非常低，低，高，非常高）的VSS消费强度。在计划的实验中，VSS-预先和VSS征服阶段将交替。对于不同的阶段，预期应力和VSS消耗强度的不同影响。除了fMRI数据外，还将收集体液，形态计量学，连通性，外围生理学，行为和主观数据。此外，人格特征，VSS消费动机以及心理病理症状将由问卷评估。这些数据为中介和主持人分析提供了有关压力和VSS消耗强度对VSS处理的影响的显着数据基础。这将导致有关VSS过度和控制性消耗行为的发展涉及的关键因素的可检验假设。
