Visual stimuli refer to any visual cues or information that are presented to an individual's eyes and processed by the visual system. This can include images, videos, patterns, colors, shapes, and more. Research in this area often focuses on how individuals perceive and interpret visual stimuli, how different types of visual stimuli impact cognition and behavior, and how visual stimuli are processed in the brain. This research is important for understanding how humans interact with their visual environment and can have implications for fields such as psychology, neuroscience, marketing, and design.
