I remember learning that a pseudoscalar is one that changes sign under a parity inversion, like the determinant of a matrix. Pseudoscalar particles have parity eigenvalue 1. Why is it that pseudovector particles have parity value +1?

An ordinary vector changes sign under a parity inversion, so a pseudovector must not.

I think I get it. A pseudovector, after being reflected, is also reversed in direction. A vector is simply reflected.
