How different people confuse the terms
Bottom up, top down, perceived interest and overall gaze

studies from engelke and Wang, is importance map related to saliency?

Top Down factors influencing attention

inhibition of return to the same area
Occulomotor and orientation biases
Effects of the task and story

Bottom-up Saliency factors influencing attention

Popout and temporal surprise
Centre surround saliency
Neurological basis of centre-surround and bottom-up filters
