Auditory extinction is the failure to hear simultaneous stimuli on the left and right sides. This extinction is also caused by brain damage on one side of the brain where awareness is lost on the contralesional side. Affected people report the presence of side-specific phonemes, albeit extinguishing them at the same time. This indicates that ...
The following criteria are required to classify an event as an inattentional blindness episode: 1) the observer must fail to notice a visual object or event, 2) the object or event must be fully visible, 3) observers must be able to readily identify the object if they are consciously perceiving it, [3] and 4) the event must be unexpected and the failure to see the object or event must be due ...
The dominant account of extinction involves associative models. However, there is debate over whether extinction involves simply "unlearning" the unconditional stimulus (US) – Conditional stimulus (CS) association (e.g., the Rescorla–Wagner account) or, alternatively, a "new learning" of an inhibitory association that masks the original excitatory association (e.g., Konorski, Pearce and ...
Visual spatial attention is a form of visual attention that involves directing attention to a location in space. Similar to its temporal counterpart visual temporal attention , these attention modules have been widely implemented in video analytics in computer vision to provide enhanced performance and human interpretable explanation [ 1 ] [ 2 ...
Attention allows a person to identify and react to pertinent objects in space, while ignoring other irrelevant objects. Patients with visual extinction, especially those with unilateral damage to the right parietal lobe, may be unable to attend and orient to objects in collateral space, therefore presenting neglect to visual stimuli.

Crossmodal attention refers to the distribution of attention to different senses. Attention is the cognitive process of selectively emphasizing and ignoring sensory stimuli. According to the crossmodal attention perspective, attention often occurs simultaneously through multiple sensory modalities . [ 1 ]

The scarcity of attention is the underlying assumption for attention management; the researcher Herbert A. Simon pointed out that when there is a vast availability of information, attention becomes the more scarce resource as human beings cannot digest all the information. [6] Fundamentally, attention is limited by the processing power of the ...
