It's a keeper!
This is one of those names where actively seeking a buyer will pay off. Find an online psychology site that isn't just an advertisement for some psychology firm but rather one that has psychology related content. Assess their name/site and see if it appears they could benefit from a broader more appealing name. If so, contact them and pitch your name.
With that said and assuming you find an interested party I would start out at high $x,xxx. They probably won't like that price but if you got their attention and they like the name they will probably counter offer. In the end I would say you should be able to get mid $x,xxx. I would'nt settle for less than low $x,xxx.
Reseller you are probably looking at low $xxx.
Good luck!
