Emotional stimuli such as images, words, or video clips are often used in studies researching emotion. New sets are continuously being published, creating an immense number of available sets and complicating the task for researchers who are looking for suitable stimuli. This paper presents the KAPODI-database of emotional stimuli sets that are freely available or available upon request. Over 45 aspects including over 25 key set characteristics have been extracted and listed for each set. The database facilitates finding of and comparison between individual sets. It currently contains sets published between 1963 and 2020. A searchable online version ( https://airtable.com/shrnVoUZrwu6riP9b ) allows users to select specific set characteristics and to find matching sets accordingly, as well as to add new published sets.

Emotional stimuli such as images, words, music, speech, or video-clips are often used in studies researching emotion. Over the past decades, new sets have continuously been published and presented to the research community. The immense number of available sets can complicate the task when researchers are looking for suitable stimuli for their study.This paper presents the comprehensive work of the creation of a database currently including 364 stimuli sets published between 1963 and 2020. All included sets are freely available or available upon request. Over 45 aspects, including over 25 key set characteristics such as sort, number and resolution of included stimuli; rating scales; included emotions; age, gender and number of raters; or, age, gender and number of models, have been extracted and listed for each stimuli set. A searchable online version of the database allows users to select specific set characteristics and to find matching stimuli sets accordingly. The KAPODI searchable database facilitates finding of and comparison between individual sets, and therefore provides a useful resource for researchers aiming to access emotional stimuli sets.
