Visual attention refers to the cognitive process by which individuals selectively concentrate on specific aspects of the visual environment while ignoring others. This process allows individuals to focus on relevant information, filter out distractions, and efficiently allocate their limited cognitive resources. Research in visual attention examines how individuals prioritize and process visual information, how attention is directed and controlled, and how attentional processes interact with perceptual and cognitive processes. This research area is important for understanding how humans perceive and interact with their surroundings, as well as for designing effective visual displays and interfaces in various fields such as psychology, neuroscience, and human-computer interaction.
