Final answer:
In a cognitive psychology lab test, a man with blindsight would demonstrate visual processing abilities without conscious awareness, such as detecting motion without consciously seeing it. This emphasizes the visual system's complexity and our selective attention.
Step-by-step explanation:
If a man being tested in a cognitive psychology lab exhibits blindsight, he would demonstrate some visual processing abilities without conscious awareness. This condition means that while he may not have conscious visual perception, certain aspects of vision like detecting the motion or location of an object still function. People with blindsight may respond to visual stimuli without consciously experiencing them. For example, if a ball is thrown towards them, they may catch it, but not because they 'see' it in the way most people do. This phenomenon highlights the complexity of the visual system and how it processes information in the brain.
In research on visual attention and perception, experiments like the one conducted by Simons and Chabris in 1999 demonstrate how selective our visual attention can be. Participants were so focused on counting basketball passes that they failed to notice a person in a gorilla suit on the screen. This illustrates inattentional blindness, where noticeable things can be missed if our attention is directed elsewhere.
