It refers to the direct and unmediated experience in case of humans.
A person might be an different in his ethnicity but he would care about the host country because he and everyone else in the particular country experiences things in an 'immediate' way.
Another example of 'immediate' is Shakespeare's works which are essentially an 'immediate presentation' as Dryden had said of Shakespeare's dramas that he drew from nature not 'laboriously but luckily' which leads to a body of work which is not mediated and has universal aspects to it.
