Description: **Abstract** The vast majority of research on human emotional tears has relied on posed and static stimulus materials. In this paper, we introduce the Portsmouth Dynamic Spontaneous Tears Database (PDSTD), a free resource comprising video recordings of 24 female encoders depicting a balanced representation of sadness stimuli with and without tears. Encoders watched a neutral film and a self-selected sad film and reported their emotional experience for 9 emotions. Extending this initial validation, we obtained norming data from an independent sample of naïve observers (N = 91, 45 females) who rated the expressions on 7 discrete emotions, negative and positive valence, arousal, and genuineness during three time phases (neutral, pre-sadness, sadness), yielding a total of 72 recordings. All data were analyzed by means of general linear mixed modelling (GLMM) to account for sources of random variance. Our results confirm the successful elicitation of sadness, and demonstrate the presence of a tear effect, i.e., a substantial increase in perceived sadness for spontaneous dynamic weeping. To our knowledge, the PDSTD is the first database of spontaneously elicited dynamic tears and sadness that is openly available to researchers. The stimuli can be accessed free of charge from this repository and may be used by other researchers for the purposes of new research studies as well as in presentations. **How to obtain access to the database videos:** The participants whose videos are included in this database signed an extended consent (University of Portsmouth ethics committee reference number: SFEC 2018-011) covering the use of their videos for creating the database as well as the following purposes: 1. Consent for their videos to be used in future experiments where they will be seen by others 2. They understand that the results of studies may be published and / or presented at meetings or academic conferences and may be provided to research commissioners or funders. They consented for their anonymous data, which does not identify them, to be disseminated in this way. 3. They agreed to the data being retained for any future research that has been approved by a Research Ethics Committee. 4. They consented for videos of them to be taken during the experiment for use in scientific presentations and publications (identity may not be obscured). As a researcher, you can therefore request access to the following two components: * The PDSTD videos of Weepers: https://osf.io/83g4b/ * The PDSTD videos of Non-Weepers: https://osf.io/abxsu/ Please ensure that your OSF profile information includes all relevant information required to verify your status as a researcher (e.g., university or other type of research institution) when sending the requests. Note that by sending this request, you confirm that your intended use of these materials is for research purposes as defined above. You do not need to send any detailed information concerning your research project. Please further note that as per the EU General Data Protection Regulation, Art. 13, participants who provided these videos might make use of their right to withdraw their consent at any time. In order for us to be able to implement any such potential requests, accepting your request for access to the video components (as per the links above) will automatically add you to the list of read-only access contributors to these two project components. You can unsubscribe from these components at any time and without the need to state any reasons. However, by unsubscribing from this component, you confirm that you will no longer be using these videos, and that you have deleted all local copies of them. For the same reason, you are furthermore not allowed to re-share these materials by any other means than through the official OSF-links stated in the paper and in the project description.
