Visual Attention Drawn to Meaning, Not What Stands Out

Our visible courtesy is drawn to tools of a stage that have meaning, rather than to those that are distinct or “stick out,” according to new investigate from a Center for Mind and Brain during a University of California, Davis. The findings, published in a journal Nature Human Behavior, overturn a widely-held indication of visible attention.

“A lot of people will have to rethink things,” pronounced psychology highbrow John Henderson, who led a research. “The saliency supposition unequivocally is a widespread view.”

Our eyes understand a far-reaching margin of perspective in front of us, nonetheless we usually concentration a courtesy on a tiny partial of this field. How do we confirm where to approach a attention, but meditative about it?

The widespread speculation in courtesy studies is “visual salience,” Henderson said. Salience means things that “stick out” from a background, like colorful berries on a credentials of leaves or a brightly illuminated intent in a room.

Saliency is comparatively easy to measure. You can map a volume of saliency in opposite areas of a design by measuring relations contrariety or brightness, for example.

Henderson called this a “magpie theory”: Our courtesy is drawn to splendid and glossy objects.

“It becomes obvious, though, that it can’t be right,” he said, differently we would constantly be distracted.

Making a map of meaning

Henderson and postdoctoral researcher Taylor Hayes set out to exam either courtesy is guided instead by how “meaningful” we find an area within a view. They initial had to erect “meaning maps” of exam scenes, where opposite tools of a stage had opposite levels of definition to an observer.

To make their definition maps, Henderson and Hayes took images of scenes, pennyless them adult into overlapping round tiles and submitted a particular tiles to a online crowdsourcing use Mechanical Turk, seeking users to rate a tiles for meaning.

Based on a voting results, a researchers reserved levels of definition to opposite areas of images and combined definition maps allied to saliency maps of a same scenes.

Next, they tracked a eye movements of volunteers as they looked during a scenes. Those eyetracks gave them maps of what tools of images captivated a many attention. These “attention maps” were closer to a definition maps than a saliency maps, Henderson said.

In hunt of meaning

Henderson and Hayes don’t nonetheless have organisation information on what creates partial of a stage meaningful, nonetheless they have some ideas. For example, a cluttered list or shelf captivated some-more courtesy than a rarely distinct dash of object on a wall. With serve work, they wish to rise a “taxonomy of meaning,” Henderson said.

Although a investigate is directed during a elemental bargain of how visible courtesy works, there could be some near-term applications, Henderson said, for example, in building programmed visible systems that concede computers to indicate confidence footage or to automatically brand or heading images online.
