Positive Testing is carried with positive perceptions in otherwords testing carried out on the module taking input values which match the customer requirements.

Negative Testing is carried with negative perceptions in otherwords testing carried out on the module taking input values which donot match the customer requirements.

Positive Testing is carried with an idea of checking whether the Application works as per requirements or not. In otherwords making sure of whether the system does what it should really is intended to do(generally this is a typical developer's attitude)

Negative Testing is trying to make sure that the application does what it should not and does not what it should (generally this is a typical tester's attitude)
