[The retention of a color image in short-term memory]

The article deals with the study of the dynamics of retention of a colour image in the short-term memory by a technique of multidimensional scaling under conditions of delayed administration of a second stimulus in a pair. Comparison of colour spaces of the short-term memory (delays of 4, 15, and 60 sec) with the perceptive space without any delay showed that the four-dimensional spherical structure of the colour space remained stable, but the accuracy of assessments decreased with increase of the delay time. This led to a deterioration of the metrical determinacy of the space and an increase in the thickness of the spherical layer.
