1. Sensation is the detection of physical stimuli by sensory receptors, while perception is the interpretation of sensory information by the brain. 2. The visual system detects color, brightness, and hue, using rods and cones in the retina to detect light, rather than functioning like a camera. 3. Gestalt principles describe how the brain organizes visual elements into meaningful patterns through principles of proximity, similarity, closure, and continuity.
