Many studies require standardized and replicable protocols composed of emotional stimuli. To this aim, several databases of emotional pictures are available. However, there are only few images directly depicting interpersonal violence, which is a specific emotion evocative stimulus for research on aggressive behavior or post-traumatic stress disorder. The objective of the current study is to provide a new set of standardized stimuli containing images depicting interpersonal situations (both positive and negative). This will allow a sensitive assessment of a wide range of cognitions linked to social interaction (empathy, perspective taking, traumatic experiences, etc.). To this aim, 240 participants rated the valence and arousal of 79 pictures collected from online sources in 2018. Results showed (1) a distinctive pattern of valence and arousal regarding the picture content and (2) specific associations between those two dimensions. Taken together, these results suggest a good reliability of the selected images. In conclusion, our study provides an open access set of recent pictures depicting interpersonal situations along with normative valence and arousal ratings, that are available for download from: https://osf.io/ak4m7/?view_only=None.
许多研究需要由情绪刺激组成的标准化且可重复的方案。为此，有几个情绪图片数据库可供使用。然而，直接描绘人际暴力的图像很少，而人际暴力是研究攻击行为或创伤后应激障碍的一种特定的情绪唤起刺激。本研究的目的是提供一组新的标准化刺激，其中包含描绘人际情境（包括积极和消极情境）的图像。这将有助于对与社会互动相关的广泛认知（同理心、换位思考、创伤经历等）进行敏感评估。为此，240名参与者对2018年从网上收集的79张图片的效价和唤醒程度进行了评分。结果显示：（1）图片内容的效价和唤醒程度呈现出独特的模式；（2）这两个维度之间存在特定关联。综合来看，这些结果表明所选图像具有良好的可靠性。总之，我们的研究提供了一组可公开获取的近期图片，这些图片描绘了人际情境，并带有标准化的效价和唤醒程度评分，可从以下网址下载：https://osf.io/ak4m7/?view_only=None 。
