Experimental data on structure of "important other" perception in senior schoolchildren include a compact list of semantically equidistant descriptors of importance of the other. The schoolchildren used the list for the evaluation of personal characteristics of 10 the most important for them persons. In order to obtain reliable results the evaluations were anonymous and the experimenters did not know the identity of described persons (instruction demanded of a participant to evaluate persons of both sexes and different age, provoking sympathy and antipathy as well). Four factors characteristic for the evaluation (emotional attractiveness, business abilities, extraordinary looks, mysteriousness) were marked out. Some of them can divide, bearing positive and negative values.
