While search rates in a sparse display are determined by the number of objects, search rates in clutter are also affected by the number of object parts.

When the objects were presented in a sparse array, search times to find the target were similar for displays composed of simple and complex objects. But when the same objects were presented as dense clutter, search functions were steeper for displays composed of complex objects.

People think that you search based on objects. You think you're seeing everything, but you're really seeing very, very little.

Weapons can come in any form. Baggage checkers don't know exactly what they're looking for.

Online advertising is display plus search.

My husband and I go to Mexico every year and we collect blown decorative glass objects and we display them on shelves in the restaurant. The first time they danced, everything was shaking pretty good. But now we take all the glass off the ledge before they dance.
