In a recent New York Times<\/a> article, auditory neuroscientist\u00a0Seth S. Horowitz<\/a> of Brown University dove into the science and art of listening. Enjoy the post below learning exactly what the difference is between hearing and listening.<\/p>\n HERE\u2019S a trick question. What do you hear right now?<\/p>\n If your home is like mine, you hear the humming sound of a printer, the low throbbing of traffic from the nearby highway and the clatter of plastic followed by the muffled impact of paws landing on linoleum \u2014 meaning that the cat has once again tried to open the catnip container atop the fridge and succeeded only in knocking it to the kitchen floor.<\/p>\n The slight trick in the question is that, by asking you what you were hearing, I prompted your brain to take control of the sensory experience \u2014 and made you listen rather than just hear. That, in effect, is what happens when an event jumps out of the background enough to be perceived consciously rather than just being part of your auditory surroundings. The difference between the sense of hearing and the skill of listening is attention.<\/p>\n <\/p>\n Hearing is a vastly underrated sense. We tend to think of the world as a place that we see, interacting with things and people based on how they look. Studies have shown that conscious thought takes place at about the same rate as visual recognition, requiring a significant fraction of a second per event. But hearing is a quantitatively faster sense. While it might take you a full second to notice something out of the corner of your eye, turn your head toward it, recognize it and respond to it, the same reaction to a new or sudden sound happens at least 10 times as fast.<\/p>\n This is because hearing has evolved as our alarm system \u2014 it operates out of line of sight and works even while you are asleep. And because there is no place in the universe that is totally silent, your auditory system has evolved a complex and automatic \u201cvolume control,\u201d fine-tuned by development and experience, to keep most sounds off your cognitive radar unless they might be of use as a signal that something dangerous or wonderful is somewhere within the kilometer or so that your ears can detect.<\/p>\n This is where attention kicks in.<\/p>\n Attention is not some monolithic brain process. There are different types of attention, and they use different parts of the brain. The sudden loud noise that makes you jump activates the simplest type: the\u00a0startle<\/a>. A chain of five neurons from your ears to your spine takes that noise and converts it into a defensive response in a mere tenth of a second \u2014 elevating your\u00a0heart rate<\/a>, hunching your shoulders and making you cast around to see if whatever you heard is going to pounce and eat you. This simplest form of attention requires almost no brains at all and has been observed in every studied vertebrate.<\/p>\n More complex attention kicks in when you hear your name called from across a room or hear an unexpected birdcall from inside a subway station. This stimulus-directed attention is controlled by pathways through the temporoparietal and inferior frontal cortex regions, mostly in the right hemisphere \u2014 areas that process the raw, sensory input, but don\u2019t concern themselves with what you should make of that sound. (Neuroscientists call this a \u201cbottom-up\u201d response.)<\/p>\n
