You can't draw perfectly straight lines between this sort of study and real-world negotiations, of course, but the researchers are pretty sure they know what's going on here: Simply put, the presence of two values causes the perception of the reservation price to climb upward a bit relative to what it would be if only the lower number were there.
Good luck, job seekers.
