WebbA Model of Visual Attention is a description of the observed and/or predicted behavior of human (or animal) visual attention. Models can use natural language, system block diagrams, mathematics, algorithms, or computations as their embodiment and attempt to mimic, explain, and/or predict some or all of visual attentive behavior. WebbUnderstanding the perceptual, cognitive, and neural mechanisms that mediate selective attention is a core issue in cognitive neuroscience. One prominent model of selective attention, known as load theory, offers an account of how task demands determine when information is selected and an account of the efficiency of the selection process. ctra stock yield https://reesesrestoration.com
