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, retain, and compare visual information from one glance to the next; our awareness of our visual surroundings is far more sparse than most people intuitively believe. These failures of awareness and the erroneous intuitions that often accompany them have both theoretical and practical ramifications…

C Change Blindness

Change blindness is a phenomenon of visual attention in which changes to a visual scene may go unnoticed under certain circumstances, despite being clearly visible and possibly even in an attended

Change blindness: past, present, and future

Change Detection Without Awareness: Do Explicit Reports Underestimate the Representation of Change in the Visual System?

Evidence from many different paradigms (e.g. change blindness, inattentional blindness, transsaccadic integration) indicate that observers are often very poor at reporting changes to their visual

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.

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

Change Blindness Images

This paper presents the first computational model of change blindness to quantify the degree of blindness between an image pair, which comprises a novel context-dependent saliency model and a measure of change, the former dependent on the site of the change, and the latter describing the amount of change.

A Three-Feature Model to Predict Colour Change Blindness

A fully automated model to predict colour change blindness in cartoon images based on image complexity, change magnitude and observer experience is introduced and the predictions of the proposed model correlate significantly with measured detection times.

Beyond the Grand Illusion : What Change Blindness

Experiments on scene perception and change blindness suggest that the visual system does not construct detailed internal models of a scene. These experiments therefore call into doubt the traditional

Detecting changes in real-world objects: The relationship between visual long-term memory and change blindness

This work demonstrates that long-term memory is capable of storing a massive number of visual objects with significant detail about each item if they are given sufficient time to encode each item.

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.



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

Failure to detect changes to people during a real-world interaction

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

In Sight, Out of Mind: When Object Representations Fail

Models of human visual memory often presuppose an extraordinary ability to recognize and identify objects, based on evidence for nearly flawless recognition of hundreds or even thousands of pictures

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.

Solving the "real" mysteries of visual perception: the world as an outside memory.

This paper discusses several defects of vision and the classical theories of how they are overcome, and suggests an alternative approach, in which the outside world is considered as a kind of external memory store which can be accessed instantaneously by casting one's eyes (or one's attention) to some location.

The results suggest that Gestalt grouping does occur without attention but that the patterns thus formed may not be encoded in memory without attention.

Relation between cognitive and motor-oriented systems of visual position perception.

Although subjects failed to detect a target displacement if it occurred near the time of a saccadic eye movement (a cognitive visual task), they were still able to point to the center of the target

Blind to Object Changes: When Learning the Same Object at Different Levels of Categorization Modifies Its Perception

The perceptual features people extract from objects depend on how they typically categorize them. It is now commonly acknowledged that the human perceiver can interact with the objects of his or her

Fleeting memories : cognition of brief visual stimuli

The investigation of what people understand and remember from rapidly presented sequences of visual stimuli began in the late 1960s. In this book prominent researchers approach the topic from
