With each eye fixation, we experience a richly detailed visual world. Yet recent work
on visual integration and change direction reveals that we are surprisingly unaware of the details
of our environment from one view to the next: we often do not detect large changes to objects
and scenes (`change blindness'). Furthermore, without attention, we may not even perceive
objects (`inattentional blindness'). Taken together, these findings suggest that we perceive and
remember only those objects and details that receive focused attention. In this paper, we briefly
review and discuss evidence for these cognitive forms of `blindness'. We then present a new study
that builds on classic studies of divided visual attention to examine inattentional blindness for
complex objects and events in dynamic scenes. Our results suggest that the likelihood of noticing
an unexpected object depends on the similarity of that object to other objects in the display and
on how difficult the priming monitoring task is. Interestingly, spatial proximity of the critical
unattended object to attended locations does not appear to affect detection, suggesting that
observers attend to objects and events, not spatial positions. We discuss the implications of these
results for visual representations and awareness of our visual environment.
