What ten sounds are most likely to make you react?

At Fast Company, Author Martin Lindstrom writes about an informal study conducted by his company Buyology Inc. and Elias Arts, a New York-based "sound identity company," to explore which sounds would most reliably cause involuntary responses in listeners. "Baby giggle," demonstrated so effectively by the little duderino in the video above, was number one on the list. Among branded sounds, the "Intel sound" was tops. Neuromarketers, listen up:
