Paper Abstract

We analyzed how much motion coherence was needed to detect a target group of three moving dots in a dynamic visual noise background and how the addition of color helps to achieve this coherence. In order to do this, 171 different situations were analyzed: the amount of noise dots, three different organizations of the samples, and different achromatic and chromatic situations both in the backgrounds and in the samples. The results indicate that: collinear targets are easily recognizable; in an achromatic situation the increase of noise dot produces a sharp decrease in recognition; color of the dots, particularly if the color is in opponence to the background color, re-establishes this loss. The results also indicate that movement and form regularity do not appear to be additive but are interactive.
