“…Therefore, we expected RSVP accuracy to be much better in Experiment 2 than in Experiment 1. The silhouette was always presented two items prior to the target letter-the lag at which Folk et al (2002) observed the greatest attentional capture effects. Note, however, that the temporal lag between the distractor and the target was variable in Folk et al's experiment whereas in Experiment 2, we used a fixed lag between the silhouette and the RSVP target.…”

“…As in Experiment 1, participants in Experiment 2 performed a difficult RSVP task at fixation, but because our interest here is in testing whether our task-irrelevant stimuli are more likely to capture attention when they appear in the RVF rather than the LVF, the procedure was adapted in order to be optimal for measuring attentional effects from a peripheral stimulus on performance (cf., Folk et al, 2002). Each trial began with a central fixation cross; the participant pressed the space bar when ready to begin.…”

Multiple objects compete for representation in visual cortex. Competition may also underlie the perception of a single object. Computational models implement object perception as competition between units on opposite sides of a border. The border is assigned to the winning side, which is perceived as an object (or " figure"), whereas the other side is perceived as a shapeless ground. Behavioral experiments suggest that the ground is inhibited to a degree that depends on the extent to which it competed for object status, and that this inhibition is relayed to low-level brain areas. Here, we used fMRI to assess activation for ground regions of task-irrelevant novel silhouettes presented in the left or right visual field (LVF or RVF) while participants performed a difficult task at fixation. Silhouettes were designed so that the insides would win the competition for object status. The outsides (grounds) suggested portions of familiar objects in half of the silhouettes and novel objects in the other half. Because matches to object memories affect the competition, these two types of silhouettes operationalized, respectively, high competition and low competition from the grounds. The results showed that activation corresponding to ground regions was reduced for high-vs. low-competition silhouettes in V4, where receptive fields (RFs) are large enough to encompass the familiar objects in the grounds, and in V1/V2, where RFs are much smaller. These results support a theory of object perception involving competitionmediated ground suppression and feedback from higher to lower levels. This pattern of results was observed in the left hemisphere (RVF), but not in the right hemisphere (LVF). One explanation of the lateralized findings is that task-irrelevant silhouettes in the RVF captured attention, allowing us to observe these effects, whereas those in the LVF did not. Experiment 2 provided preliminary behavioral evidence consistent with this possibility.

“…A slightly different version of RSVP experiments has looked at how RSVP target processing is affected by distractors presented at separate locations surrounding the central RSVP stream (Folk, Leber, & Egeth, 2002;Jiang & Chun, 2001). In Jiang and Chun's (2001) study, flanking distractors interfered with, or facilitated identification of, the second RSVP target (depending on the distractor-target compatibility) when the lag between first and second target was short but not when the lag was long.…”

The detection or discrimination of the second of 2 targets in a rapid serial visual presentation (RSVP) task is often temporarily impaired-a phenomenon termed the attentional blink. This study demonstrated that the attentional blink also affects localization performance. Spatial cues pointed out the possible target positions in a subsequent visual search display. When cues were presented inside an attentional blink (as induced by an RSVP task), the observers' capacity to use them was reduced. This effect was not due to attention being highly focused, to general task switching costs, or to complete unawareness of the cues. Instead, the blink induced a systematic localization bias toward the fovea, reflecting what appears to be spatial compression.

“…performance during visual searching is impaired only when targets are preceded by distractors carrying task-relevant features (Du & Abrams, 2008;Folk, Leber, & Egeth, 2002;Serences, Shomstein, Leber, Golay, Egeth, & Yantis, 2005).…”

We investigated whether attentional set is available at the beginning of a trial or whether it develops gradually within a trial. Thus, we manipulated the time from the onset of a trial to a target and observers' search strategy. We also observed the effect of the presence or absence of distractors as an index of the temporal development of attentional set. Participants identified a target letter embedded in a stream of rapidly presented nontargets while ignoring peripheral distractors. Baseline accuracy when no peripheral distractor was presented increased as the target appeared later in the stream, suggesting attentional awakening. Identification accuracy was impaired by the presence of peripheral distractors (i.e., attentional capture) early in the stream only when observers adopted the feature search mode. The magnitude of attentional capture increased over the course of the first 1, 000 ms of a trial under the singleton detection and feature search modes. These results suggest that singleton detection mode requires time for a bottom-up signal to be effective in capturing attention, whereas the feature search mode does not require such a warm-up period to be effective and is available from the beginning of viewing the stream.
