Inhibition of return (IOR)
The relative difficulty in getting attention (or the eyes) to move back to a recently attended (or fixated) location.
spotlight model
attention is restricted in space and moves from one point to hte next. areas within the spotlight receive extra processing
zoom lens model
the attended region can grow or shrink depending on the size of the area to be processed.
