对情感表达的研究得到了数据库的支持。审查可用资源使我们相信有必要开发一个优先考虑生态有效性的资源。数据库的基本单位是一个剪辑，这是一个视听记录的一集，似乎是合理的自足。剪辑范围从10 - 60秒，并捕获为MPEG文件。它们来自两个主要来源。研究人员记录了人们在相互之间或与研究团队中的一个人讨论情感主题的情况。我们还记录了电视节目的片段，在这些节目中，公众以一种至少看起来基本上是自发的方式进行互动。与每个剪辑关联的还有两种其他类型的文件。音频文件（.wav格式）仅包含语音，经过编辑以删除除主扬声器之外的声音。一个解释文件描述了观察者归因于主要发言者的情绪状态，使用FEELTRACE系统提供了一个连续的记录，记录了感知到的情绪起伏。100个发言者的剪辑被提取出来，每个发言者至少有两个（一个相对中立，其他人表现出不同类型的明显情绪）。
Research on the expression of emotion is underpinned by databases. Reviewing available resources persuaded us of the need to develop one that prioritised ecological validity. The basic unit of the database is a clip, which is an audiovisual recording of an episode that appears to be reasonably selfcontained. Clips range from 10 – 60 secs, and are captured as MPEG files. They were drawn from two main sources. People were recorded discussing emotive subjects either with each other, or with one of the research team. We also recorded extracts from television programs where members of the public interact in a way that at least appears essentially spontaneous. Associated with each clip are two additional types of file. An audio file (.wav format) contains speech alone, edited to remove sounds other than the main speaker. An interpretation file describes the emotional state that observers attribute to the main speaker, using the FEELTRACE system to provide a continuous record of the perceived ebb and flow of emotion. Clips have been extracted for 100 speakers, with at least two for each speaker (one relatively neutral and others showing marked emotions of different kinds).
