Fear certainly seems to attract bears, although many bear attacks have occurred so suddenly that the human attacked never even knew they were being tracked by a bear. But I have heard one story of a mauling where the female of the couple stood her ground and tried the talk the bear down ("hey bear, hey bear") and the male of the couple panicked and tried to run away. He got about two steps before the sow brown bear got him across the face with her paw. The bear never went after the female hiker. The sow then took off into the trees to her cubs once she felt the "threat" had been neutralized. The male hiker had extensive facial injuries but survived and today you have to know what happened to see the scars. Anyway, the female hiker felt that it was the fear in her partner that had triggered the attack on him as until he panicked and started to run, the bear had seemed to be bluff charging and the hikers were backing off.

I can't see what I'm typing now so I'll ppost this.
