Visual change detection often fails when observers’ attention is distracted by some other visual disruptions in the environment that occur simultaneously with the change. This phenomenon is called change blindness. It has been claimed that selective attention is necessary for successful change detection. In the current experiment, two mechanisms of attention allocation in such a task were investigated. First, the number of distracting stimuli was varied to distract observers’ attention and…

Eye movements during change detection: the role of depth of field

This study investigates the eye movements when detecting changes in the scene with different levels of depth of field. A within-subjects experiment was conducted using a flicker paradigm to create

The Role of Iconic Memory in Change-Detection Tasks

It is concluded that people may have a fairly rich visual representation of a scene while the scene is present, but fail to detect changes because they lack the ability to simultaneously represent two complete visual representations.

Unvoluntary attentional capture in change blindness.

The results indicate that the transient of the change, although never occluded by mudsplashes, did not attract attention automatically but additional knowledge about its occurrence is necessary (top down).

Electrophysiological correlates of stimulus processing in change blindness

The N2pc cannot be taken as a direct correlate of awareness but rather as a marker for a process that is necessary but not sufficient for awareness.

ERP effects of change localization, change identification, and change blindness

Effects of localization with and without identification were remarkably similar on a sequence of event-related potential components (including change-related positivity and N2pc), indicating that change localization and change identification initially rely on a common processing sequence and differ only at later stages.

The N2pc as an Electrophysiological Correlate of Attention in Change Blindness

Changes between two successively presented pictures are hard to detect when their presentation is interrupted by a blank (change blindness). This task is well established for investigating the neural

Neural mechanisms of selective visual attention.

The two basic phenomena that define the problem of visual attention can be illustrated in a simple example and selectivity-the ability to filter out un­ wanted information is illustrated.

TO SEE OR NOT TO SEE: The Need for Attention to Perceive Changes in Scenes

When looking at a scene, observers feel that they see its entire structure in great detail and can immediately notice any changes in it. However, when brief blank fields are placed between

Current Approaches to Change Blindness

Across saccades, blinks, blank screens, movie cuts, and other interruptions, observers fail to detect substantial changes to the visual details of objects and scenes. This inability to spot changes

Involuntary Attentional Capture is Determined by Task Set: Evidence from Event-related Brain Potentials

The results do not support previous claims that attentional capture is initially unaffected by topdown intention, and demonstrate the central role of task set in involuntary attentional orienting.
