Sexual objectification – perceiving or treating a woman as a sexual object – is a widespread phenomenon. Studies on sexual objectification and its consequences have grown dramatically over the last decades covering multiple and diverse areas of research. However, research studying sexual objectification might have limited internal and external validity due to the lack of a controlled and standardized picture database. Moreover, there is a need to extend this research to other fields including the study of emotions. Therefore, in this paper we introduce the SOBEM Database, a free tool consisting of 280 high-resolution pictures depicting objectified and non-objectified female models expressing a neutral face and three different emotions (happiness, anger, and sadness) with different intensity. We report the validation of this dataset by analyzing results of 134 participants judging pictures on the six basic emotions and on a range of social judgments related to sexual objectification. Results showed how the SOBEM can constitute an appropriate instrument to study both sexual objectification per se and its relation with emotions. This database could therefore become an important instrument able to improve the experimental control in future studies on sexual objectification and to create new links with different fields of research.

性对象化——将女性视为性对象或将其视为性对象——是一种普遍现象。在过去的几十年中，关于性对象化及其后果的研究急剧增加，涵盖了多个不同的研究领域。然而，由于缺乏受控和标准化的图片数据库，研究性对象化的研究可能具有有限的内部和外部有效性。此外，有必要将这项研究扩展到其他领域，包括情绪研究。因此，在本文中，我们介绍了 SOBEM 数据库，这是一个免费工具，由 280 张高分辨率图片组成，这些图片描绘了客观化和非客观化的女性模特，表达了中性面孔和三种不同强度的情绪（快乐、愤怒和悲伤）。我们通过分析 134 名参与者根据六种基本情绪和一系列与性客观化相关的社会判断判断图片的结果来报告该数据集的验证。结果表明，SOBEM 如何构成一个合适的工具来研究性客观化本身及其与情绪的关系。因此，该数据库可以成为一个重要的工具，能够在未来的性客观化研究中改进实验控制，并与不同的研究领域建立新的联系。
