Target objects presented within color images of naturalistic scenes were deleted or rotated during a saccade to or from the target object or to a control region of the scene. Despite instructions to memorize the details of the scenes and to monitor for object changes, viewers frequently failed to notice the changes. However, the failure to detect change was mediated by three other important factors: First, accuracy generally increased as the distance between the changing region and the fixation…

Change detection in the flicker paradigm: The role of fixation position within the scene

A major role for fixation position is suggested in the detection of changes to natural scenes across discrete views and participants detected scene changes more accurately, with fewer false alarms, and more quickly when allowed to move their eyes in the scene than when required to maintain central fixation.

Eye movements and visual memory: Detecting changes to saccade targets in scenes

In the present study, critical objects presented within color images of naturalistic scenes were changed during a saccade toward or away from the target, and detection performance for type and token changes, both when the changing object was the target of the saccades and when the object had just been fixated but was not the sAccade target, was well above chance.

Change perception using visual transients: object substitution and deletion

Contrary to previous findings showing that response times for luminance change detection in a multi-element display are not altered by attention, it is found changes in Objects of central interest to be detected faster than in objects of marginal interest when objects’ identity was to be held in working memory.

To see and remember: Visually specific information is retained in memory from previously attended objects in natural scenes

Three findings support the two competing hypotheses regarding the accumulation of visual information during scene viewing that visual representations do not necessarily decay upon the withdrawal of attention, but instead can be accumulated in memory from previously attended regions.

Overt attentional prioritization of new objects and feature changes during real-world scene viewing

The authors investigated the extent to which a change to an object's colour is overtly prioritized for fixation relative to the appearance of a new object during real-world scene viewing. Both types

Eye movements and picture processing during recognition

It is concluded that information about object presence and identity in a scene is limited to a relatively small region around the current fixation point.

Accurate visual memory for previously attended objects in natural scenes

The nature of the information retained from previously fixated (and hence attended) objects in natural scenes was investigated. In a saccade-contingent change paradigm, participants successfully

Prioritization of new objects in real-world scenes: evidence from eye movements.

These effects were not modulated by observers' expectations concerning the appearance of new objects, suggesting the prioritization of a transient is automatic and that memory-guided prioritization is implicit.

Abstract : An accurate and detailed representation of the environment is presumed to help observers notice when an object moves or changes. Unfortunately, when change in the environment coincides

Failure to detect changes to attended objects in motion pictures

Our intuition that we richly represent the visual details of our environment is illusory. When viewing a scene, we seem to use detailed representations of object properties and interobject relations

Visual stability across saccades while viewing complex pictures.

Evidence suggests that subjects' detection of image changes primarily involves the use of local information in the region of the eyes' landing position, and a saccade target theory of visual stability is proposed.

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

It was concluded that some information is stored from the visual periphery during picture viewing after a two-alternative forced-choice recognition test in which the targets and distractors differed in only a single, critical detail.
