The sensory enhancement theory assumes that attentional resources will spread until they reach the boundaries of a cued object, [1] [2] including regions that may be obstructed or are overlapping other objects. [3] [4] It has been suggested that sensory enhancement is an essential mechanism that underlies object-based attention.
Object-based attentional effects are attributed to the improved sensory representation of the object that results from attentional spread (an object-guided spatial selection). [ 8 ] : 1 [ 9 ] : 1 When attention is directed to a location within an object, other locations within that object also acquire an attentional advantage (via enhanced ...
Researchers in psychology and cognitive science study perceptual vigilance to understand how attentional mechanisms operate and how they can be influenced by internal and external factors. By investigating the cognitive processes underlying perceptual vigilance, researchers gain insights into human perception, behavior and decision-making. [4]
Perhaps one of the most studied sensory integrations is the relationship between vision and audition. [16] These two senses perceive the same objects in the world in different ways, and by combining the two, they help us understand this information better. [17] Vision dominates our perception of the world around us.
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] These modalities process information from the different sensory fields, such as: visual, auditory, spatial, and tactile. [2]
Perceptual load theory is a psychological theory of attention. It was presented by Nilli Lavie in the mid-nineties as a potential resolution to the early/late selection debate. [ 1 ] [ 2 ]

Feature integration theory is a theory of attention developed in 1980 by Anne Treisman and Garry Gelade that suggests that when perceiving a stimulus, features are "registered early, automatically, and in parallel, while objects are identified separately" and at a later stage in processing.
