Psychology isn't just about counselling.  That's just generally what people know it to be.  There's all sorts of other things which involve psychology.  An example could be an aircraft safety system - it needs to be designed that pilots, for example, can properly handle the situation if there's an issue.  On a similar note, it can also be applied to computer user interfaces - eg what's the easiest for someone to understand or most intuitive?  I'm not good at explaining this, but I hope you understand what I'm getting at.
