Document Summary
Light energy and eye structure: our eyes receive light energy and traduces (transform) it into neural messages that our brain then processes into what we consciously see. The stimulus: light energy: wavelength: distance from one wave peak to the next determines its hue, hue: colour we experience such as tulip"s red petals or green leaves, intensity: the amount of energy in light waves in uences brightness. In dim light they become ineffectual so you see no colour: rods, enable black and white vision, remain sensitive in dim light. For example, some cells are stimulated by green and inhibited by red; others are stimulated by red and inhibited by green. Gestalt psychologists emphasized our tendency to integrate pieces of information into meaningful wholes. Grouping: grouping: perceptual tendency to organize stimuli into coherent groups, proximity - group nearby gures, continuity - smooth continuous patters, closure - ll gaps to create whole object.
