Since I’ve been obsessed in recent months with marketing techniques and the social psychology of shopping, Dmitriy T.M. sent me a video found at Time; in the video Martin Lindstrom argues that sound can be used to encourage shoppers to buy more items.

So if you need to increase sales in your store, get a bunch of babies and have them sitting around giggling. You don’t even have to pay sound licensing fees!

NOTE: I see that a lot of commenters are discussing their personal lack of reaction to the sound of giggling babies, etc. I totally get it–I raised an eyebrow as well. But we should keep in mind that there may be a difference between actively reacting to something or caring about it greatly (say, loving kids) and being indirectly influenced by sounds that might vaguely evoke some element of it. Of course, from the video we don’t know if any business has actually been successful at getting people to buy things by using sounds similar to babies giggling (or water being poured), only that people seem to react positively to those sounds in the lab. So I don’t know how much legitimacy there is to this, but I know marketers have definitely tried to use smells to influence people to linger in an area, hopefully then leading to higher sales.
