The hypothesis suggesting that steadiness and distribution of attention are results of internal acts per-formed in mind was investigated. Steadiness (tested by task to find and fix all figures of one form among others) requires the following actions: comparison of each figure with pattern; transition to the next figure. Distribution (finding all figures of two forms in the same test) requires the same actions but arranged in two algorithms: 1) comparison with one of the patterns, fixation of identity, transition to the next figure; 2) comparison with one pattern, comparison with another one, transition to the next figure. The sequence of these algorithms is irregular and depends on position of figures. Method that improved steadiness of attention did not influence its distribution. Two groups of 3;6-4;2 year old children were taught to compare various objects with a model according to two characteristics with the help of two methods. In the retest the mistakes in the first group reduced from 83 to 13 %, in the second group - from 95 to 13 %.
