“…It has been interpreted (see O'Regan, Rensink, & Clark, 1999;Simons & Levin, 1997) as suggesting that standard introspections of perceiving a rich visual world are aǹ illusion'. We agree that change blindness provides a particularly compelling example of the in¯uence that attentional factors can have on phenomenal visual experience, as when a previously undetectable change becomes overwhelmingly salient once its location is cued.…”

Issues concerning selective attention provoke new questions about visual segmentation, and vice-versa. We illustrate this by describing our recent work on grouping under conditions of inattention, on change blindness for background events and the residual processing of undetected background changes, on modal versus amodal completion in visual search, and the differential effects of these two forms of completion on attentional processes, and on attentional modulation of lateral interactions thought to arise in early visual cortex. Many of these results indicate that segmentation processes substantially constrain attentional processes, but the reverse in¯uence is also apparent, suggesting an interactive architecture. We discuss how the`proto-objects' revealed by studies of segmentation and attention (i.e. the segmented perceptual units which constrain selectivity) may relate to other object-based notions in cognitive science, and we wrestle with their relation to phenomenal visual awareness. q

“…For example, normal observers may not notice salient changes in a visual scene (e.g. large object shifting or disappearing) when the attention-grabbing capacity of these events is disrupted by the concurrent presentation of distracting material, likè mudsplashes' [164], or when observers do not expect to see the change because they are making a dif®cult perceptual judgment about other elements in the scene [165]. In these`change blindness' experiments, normal observers are totally unaware of an important part of what is going on in their visual ®eld, and often incredulous of having missed such major modi®cations of the visual scene.…”

After right posterior brain damage, patients may ignore events occurring on their left, a condition known as unilateral neglect. Although de®cits at different levels of impairment may be at work in different patients, the frequency and severity of attentional problems in neglect patients have been repeatedly underlined. Recent advances in the knowledge of the mechanisms of spatial attention in normals may help characterizing these de®cits. The present review focuses on studies exploring several aspect of attentional processing in unilateral neglect, with particular reference to the dichotomy between`exogenous', or stimulus-related, and`endogenous', or strategy-driven, orienting of attention. A large amount of neuropsychological evidence suggests that a basic mechanism leading to left neglect behavior is an impaired exogenous orienting toward left-sided targets. In contrast, endogenous processes seem to be relatively preserved, if slowed, in left unilateral neglect. Other component de®cits, such as a general slowing of the operations of spatial attention, might contribute to neglect behavior. These results are presented and discussed, and their implications for hemispheric specialization in attentional orienting and for the mechanisms of visual consciousness are explored. q

“…Demonstrations of change blindness and inattentional blindness support this view, showing that without visual attention, significant events or changes can easily escape our awareness (Mack & Rock, 1998;O'Regan, Rensink, & Clark, 1999;Rensink, O'Regan, & Clark, 1997;Simons & Levin, 1997).…”

Perception of Objects in Natural Scenes: Is It Really Attention Free?

Studies have suggested attention-free semantic processing of natural scenes in which concurrent tasks leave category detection unimpaired (e.g., F. Li, R. VanRullen, C. Koch, & P. Perona, 2002). Could this ability reflect detection of disjunctive feature sets rather than high-level binding? Participants detected an animal target in a rapid serial visual presentation (RSVP) sequence and then reported its identity and location. They frequently failed to identify or to localize targets that they had correctly detected, suggesting that detection was based only on partial processing. Detection of targets was considerably worse in sequences that also contained humans, presumably because of shared features. When 2 targets were presented in RSVP, a prolonged attentional blink appeared that was almost eliminated when both targets were detected without being identified. The results suggest rapid feature analysis mediating detection, followed by attention-demanding binding for identification and localization.
