Soft is often used to describe non-facilitating subjects, so to answer your question both Psychology and ICT are considered softer subjects. With that in mind, it doesn't mean they're easier since different subjects suit different people. Psychology is relatively easy conceptually, however there is a lot to memorise and I mean a lot, and you've got to nail your exam technique. Considering you're taking English Literature, I would assume you don't mind essay-writing so hopefully that should help you with Psychology. I can't comment on ICT that much, but I would assume a lot of it is coursework based so as long as you keep on top of your work you'll be fine.
A Levels aren't easy by any stretch of the imagination, so you shouldn't worry too much about your subject choices. As long as your choices aren't detrimental when applying to the universities you want to apply to (assuming you want to go to university) and you're happy with the subjects you chose, you should be fine.
