Recent research on change detection has documented surprising failures to detect visual changes occurring between views of a scene, suggesting the possibility that visual representations contain few details. Although these studies convincingly demonstrate change blindness for objects in still images and motion pictures, they may not adequately assess the capacity to represent objects in the real world. Here we examine and reject the possibility that change blindness in previous studies resulted… 

Memory for centrally attended changing objects in an incidental real-world change detection paradigm.

It is shown that change blindness for a conversation partner occurs in a variety of situations, and participants who noticed the substitution showed better memory for both pre- and post-change experimenters than participants who did not detect the change.

Evidence for Preserved Representations in Change Blindness

In three experiments, it is shown that people often do have a representation of some aspects of the pre-change scene even when they fail to report the change, and they appear to "discover" this memory and can explicitly report details of a changed object in response to probing questions.

Change Blindness in the Absence of a Visual Disruption

In two experiments, it is demonstrated that change blindness can occur even in the absence of a visual disruption, and when changes are sufficiently gradual, the visible change signal does not seem to draw attention, and large changes can go undetected.

Trajectory changes are susceptible to change blindness manipulations

The study provides evidence that the flicker paradigm can be used to induce change blindness with dynamic stimuli, and that changes to predictable trajectories are detected or missed in the similar way as orientation changes.

Attentional bias in change detection

57 We live in a constantly changing environment and change detection is important in order to efficiently function in the world that surrounds us. Our sensory organs are biased to register changes in

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.

A Comparison of Change Blindness and the Visual Perception of Museum Artefacts in Real-World and On-Screen Scenarios

Change blindness is a phenomenon of visual perception that occurs when a stimulus undergoes a change without this being noticed by its observer. Since it was first described in the 1990s, change

Undetected changes in visible stimuli influence subsequent decisions

The scene and the unseen: Manipulating photographs for experiments on change blindness and scene memory

A step-by-step tutorial on how to produce changes in natural-scene images with a freely available image-processing tool (GIMP), and an experiment confirming that scenes manipulated according to these guidelines are effective in inducing change blindness and demonstrating the relationship betweenchange blindness and the physical properties of the change.

The scene and the unseen: Manipulating photographs for experiments on change blindness and scene memory

The change blindness paradigm, in which participants often fail to notice substantial changes in a scene, is a popular tool for studying scene perception, visual memory, and the link between



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

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

Is the Richness of Our Visual World an Illusion? Transsaccadic Memory for Complex Scenes

The results reveal the poverty of transsaccadic memory for real-life complex scenes and are discussed with respect to Dennett's view that much less information is available in vision than the authors' subjective impression leads us to believe.

Familiarity and visual change detection

Detection of change when one display of familiar objects replaces another display might be based purely upon visual codes, or also on identity information (i.e., knowingwhat was presentwhere in the

Change blindness

People often fail to notice large changes to visual scenes, a phenomenon now known as change blindness. The extent of change blindness in visual perception suggests limits on our capacity to encode,

Visual Attention and the Perception of Features and Objects

Feature integration theory (Treisman & Gelade, 1980) suggested that simple features are codel in parallel in a number of specialized feature maps, but that focussed attention is required to ensure

Transsaccadic Memory and Integration During Real-World Object Perception

What is the nature of the information that is preserved and combined across saccadic eye movements during the visual analysis of real-world objects? The two experiments reported investigated

Failure to integrate visual information from successive fixations

Screen brightness (2 log units above threshold) eliminated the phosphor persistence that probably accounts for the success of Jonides et al.
