Luminance changes usually co-occur with motion
changes and can themselves capture attention (Christ &
Abrams, 2008; Enns et al., 2001; Ludwig, Ranson, & Gilchrist,
2008). Here luminance changes occurred throughout
because of the rotation and motion of the gratings.
Effects of luminance changes may have interacted with
those of bounces, but this cannot explain the elimination
of the effect seen in Experiment 2, in which luminance
characteristics were identical. Bounce events are associated
with those positions on the screen farthest from the
center of the boundary boxes, hence, it is possible that the
presence of gratings in these locations attracted attention.
Bounce events may also be associated with certain speed
profiles, since very slowly moving objects, for instance,
are likely to experience fewer collisions. However, neither
of these factors can explain the elimination of the effect
observed when the boundaries were made visible
