User experience (UX) is a person's emotions and attitudes about using a particular product, system or service. This is what makes an interior designer so unique and special to you and the space. The ability to guide you gently through design choices  and open your mind to new innovative ideas, while keeping a stern understanding of the clients preferences and needs. There is a lot of common ground between both fields. Many of your skills as a psychologist will transfer smoothly to a career in UX design, including your research experience, empathy abilities, and knowledge about human behavior and the human mind.
