The focus of this brief literature review is to explore whether there is a relationship between the unique anatomical and physiological paradigms of the adolescent brain and an increased sensitivity to sexually explicit material.
The EBSCO Research Data bases were searched using the following key terms: adolescence, adolescent brain development, neuroplasticity, sexually explicit material, sexualization, and pornography.
The literature highlighted several components of the adolescent brain that are different than the mature brain. These include: an immature prefrontal cortex and over-responsive limbic and striatal circuits, heightened period for neuroplasticity, overactive dopamine system, a pronounced HPA axis, augmented levels of testosterone, and the unique impact of steroid hormones. The physiological response to sexually explicit material is delineated. The overlap of key areas associated with the unique adolescent brain development and sexually explicit material is noteworthy. A working model summary that compares the response of the adult and adolescent brain to the same sexually explicit stimulus is outlined.
The literature suggests that the adolescent brain may indeed be more sensitive to sexually explicit material, but due to a lack of empirical studies this question cannot be answered definitively. Suggestions for future research are given to further advance the work in this applicable field of today.
本次简短文献回顾的重点是探讨青少年大脑独特的解剖学和生理学模式是否与对色情材料的敏感性增加有关。
使用以下关键词在 EBSCO 研究数据库中进行搜索：青少年、青少年大脑发育、神经可塑性、色情材料、性化和色情。
文献强调了青少年大脑与成熟大脑不同的几个组成部分。这些包括：不成熟的前额叶皮层和反应过度的边缘和纹状体回路、神经可塑性增强期、过度活跃的多巴胺系统、明显的 HPA 轴、睾酮水平升高以及类固醇激素的独特影响。描述了对色情材料的生理反应。与青少年大脑发育独特相关的关键区域的重叠值得注意。概述了一个比较成人和青少年大脑对相同色情刺激反应的工作模型摘要。
文献表明，青少年的大脑可能对色情材料确实更敏感，但由于缺乏实证研究，这个问题无法得到明确回答。为了进一步推进这一当前适用领域的工作，提出了未来研究的建议。
