Can Attention be Diverted (Kan Uppmarksamheten Avledas),

Abstract

If two objects of similar shape but different contrast are searched for in a cluttered environment, the questions are posed: how much difference in contrast is needed for the object with the greater contrast to be detected first, and does detection of the first object cause delay in detecting the second object. Two experiments were carried out with the aid of a tachistoscope. One with the objects placed in a cluttered environment and the other with the objects in a terrain background. As a result it was found that it is possible with a high level of probability, to direct an observer's attention towards the desired objects, and a delaying effect can be demonstrated but many other factors capable of interfering with it.
