This is Scientific American’s 60-Second Science. I’m Christopher Intagliata. Got a minute?
On September 10th we reported that people will pay more for snacks within reach. Now, another finding for the shopping science files—when you're trying to decide between two snacks on the shelf, chances are you'll choose the one you look at just a fraction of a second longer. The study appears in the journal Nature Neuroscience.
Researchers recruited 39 students who are self-professed snack food junkies. They had the students fast for three hours, before rating the tastiness of snack foods like candy and chips. Then they asked the students to choose between pairs of snack foods they had previously 1 rated as more or less equally desirable. And they tracked the subject’s eye movements
Just like when you're hovering 2 in front of a grocery store shelf, the students looked back and forth 3 several times, usually glancing first at the snack on the left. But 70 percent of the time, they ended up choosing the snack food they looked at for just a half-second longer. Which probably confirms something packaging designers have known for a while now—flashy, eye-catching wrappers could lure 4 us into studying a snack for a bit longer—and, they hope, throwing it in our cart.
Thanks for the minute for Scientific American’s 60-Second Science. I’m Christopher Intagliata.
