Numerous studies have demonstrated that observers often fail to notice large changes in visual scenes, a phenomenon known as change blindness. Some experiments have suggested that phenomenological experience in change blindness experiments is more diverse than the common distinction between change detection and change blindness allows to resolve. Recently, it has been debated whether changes in visual scenes can be detected (“sensed”) without a corresponding perception of the changing object… 

An EEG study of detection without localisation in change blindness

The results suggest that changes can be ‘sensed’ without knowledge of the location of the changing object, and that participant certainty scores can provide valuable information about the perception of changes in change blindness.

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.

Implicit Binding of Facial Features During Change Blindness

The bidirectional modulation of the N170 component during change blindness suggests that implicit change detection can also occur at the level of complex features in the case of facial stimuli.

Explicit behavioral detection of visual changes develops without their implicit neurophysiological detectability

Findings of explicit change detection developing with and without implicit change detection may suggest that the two modes of change detection recruit independent neural mechanisms.

Change detection on a hunch: Pre-attentive vision allows “sensing” of unique feature changes

Findings suggest that pre-attentive registration of a change on a feature map can give rise to a conscious experience even when feature binding has failed: that something has changed without knowing what or where.

Attentional Modulation of Change Detection ERP Components by Peripheral Retro-Cueing

Present results confirm that the early and late ERP components related to change detection can be functionally dissociated through manipulations of exogenous retro-cueing using a change blindness paradigm.

Event-related potentials reveal rapid registration of features of infrequent changes during change blindness

The results suggest that the brain registers changes very rapidly, and that changed features in images are neurally represented even without participants' ability to report them.

Sensing and seeing associated with overlapping occipitoparietal activation in simultaneous EEG-fMRI

Both seeing and sensing a change were associated with an overlapping occipitoparietal network of activation when compared to blind trials, suggesting that the quality of the visual representation, rather than the lack of one, may result in partial awareness during the change blindness paradigm.



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.

An ERP study of change detection, change blindness, and visual awareness.

It is suggested that the earlier negativity is associated with a change in the content of visual awareness, whereas the later positivity may reflect more global processes needed in decision making and action planning.

An implicit measure of undetected change.

A simple change detection paradigm coupled with a speeded orientation discrimination task demonstrates that the nature of the change can be represented in the absence of awareness.

Time Course of Brain Activity during Change Blindness and Change Awareness: Performance is Predicted by Neural Events before Change Onset

A unique topography of event-related potential activity was observed during correct change and correct no-change reports, but not during blindness, with a recurrent time course in the stimulus sequence and simultaneous sources in the parietal and temporo-occipital cortex.

Electrophysiological correlates of change detection.

Findings demonstrate that ERPs are a useful tool for dissociating processes underlying change blindness and change detection, and suggest that short-latency ERP differences between these trial types reflect trial-by-trial fluctuations in advance task preparation, whereas differences in the P3 time range are due to variations in the duration of perceptual and decision-related processing.

Picture Changes During Blinks: Looking Without Seeing and Seeing Without Looking

Observers inspected normal, high quality colour displays of everyday visual scenes while their eye movements were recorded. A large display change occurred each time an eye blink occurred. Display

Representation of Change: Separate Electrophysiological Markers of Attention, Awareness, and Implicit Processing

The present data suggest that attention, awareness of change, and implicit representation of change may be mediated by separate underlying systems.
