科学领域:

  • 神经科学是一个神经科学.
  • 精神病学是一个精神病学.
  • 行为科学 行为科学

背景情况:

  • 问题性色情使用越来越被认可,ICD-11将其归类为强迫性行为障碍.
  • 目前还在争论它是否是一种冲动控制障碍,还是一种行为成.
  • 学习和记忆机制是成的关键,但在冲动控制障碍中不那么重要.

研究的目的:

  • 调查问题性色情使用的神经生物学基础.
  • 在色情使用中区分冲动控制障碍和行为成机制.

主要方法:

  • 功能性磁共振成像 (fMRI) 用于58名男性色情使用者 (35名无问题,23名有问题).
  • 参与者接受了食欲调节,消灭和回忆任务,使用色情,游戏和金钱的线索.
  • 记录了大脑活动,皮肤导电性反应 (SCR) 和主观评分.

主要成果:

  • 病态色情使用者在食欲调节过程中对条件刺激 (CSs) 呈现出更强烈的腹腔条纹体反应.
  • 在灭绝和回忆中改变的大脑激活是病态使用者的色情相关CS的特征.
  • 背前环状皮质和中间轨道前皮质活化增加表明对色情内容的持续性食欲记忆,得到SCR数据的支持.

结论:

  • 神经生物学发现与成理论一致,表明特定刺激的奖励敏感性和食欲记忆.
  • 这些结果支持将有问题的色情使用归类为行为成.
  • 这项研究提供了证据表明,在有问题的色情使用中,学习和记忆过程发生了变化.
