Describe what subliminal perception is and explain how the experiment discussed by the professor illustrates this phenomenon.
Subliminal Perception
Humans are constantly perceiving visual and auditory stimuli. Sometimes our perception of these stimuli occurs consciously: we are aware of a stimulus and know that we are perceiving it. But our perception of a stimulus can also occur without our awareness: an image might appear and disappear before our eyes too quickly for us to notice that we saw it, or a sound might be too faint for us to realize that we heard it. This phenomenon—the perception of a stimulus just below the threshold of conscious awareness—is called subliminal perception. Experiments have shown that subliminally perceived stimuli can influence people's thoughts and attitudes.
