If you can’t think of anything directly linked to psychology, think what kinda job you’ll be doing, and link the skills you believe you’ll need to a possible work experience later on, i mean, generally at university, alot of courses now have dedicated years to getting into work related to your course, so aslong as the work experience is relevant and shows some level of skill, go for it. Also try looking up some jobs related to psychology, and see if there are any businesses locally that do that work. I wouldn’t get too hung up on it
