Welcome to the EmoReg site! The purpose of this site is to conduct an experiment on the topic of emotion regulation through music recommendations. This research is part of my master thesis for Computer Science at Delft University of Technology in the Netherlands. This first page explains the goal of the experiment, what you'll have to do for the experiment and the requirements for participating. The entire experiment can be done on this website and mainly consists of listening to 4 songs.


The goal is to research an application which can recommend songs that will improve the emotional state of a listener. There could be many uses for this. It could for example be used in the care of elderly with dementia in healthcare facilities. In this setting we could use the research to generate a playlist which calms the person with dementia and play it when they get agitated. However this first experiment targets people without dementia. This research differs from currently existing systems (e.g. Spotify song recommendations) by focusing on improving the emotional state instead of making recommendations which are similar to what you are currently listening to.


  • A Spotify premium account
  • A desktop computer or laptop, the experiment does not work on mobile devices
  • Age: 18+

What do you have to do?

You will be asked to listen to 4 songs, while listening to these songs you will be asked some questions.

Before the experiment make sure:

  • You have 20 minutes where you will not be disturbed.
  • Your audio configuration is working.You can test this by playing:
  • You are comfortable and don’t have to go anywhere.

During the experiment:

  • Listen to the songs.
  • Answer the questions.
  • Don’t perform other activities (e.g. checking mail, browsing the web, …).

Why do I have to login with Spotify?

We require Spotify to be able to play full length songs. Additionally we also use it to receive information about tracks you have previously liked.

Data collection

During the experiment we will save all your answers to the questions you are asked. Additionally we will also save which songs you were listening to. This data will also be made available to the research community after the experiment is over. Outside of this no data will be collected. This means that all answers will be anonymous since no names, e-mail addresses or other identifying information will be collected.
