We investigated the relationship between manifestations of the emotions of fear and accuracy of human motor task. The research was conducted in two stages. At the first stage, each of 40 examinees was asked to fill out the application of the Spiel- berg - Hanina test. Then, examinees did the test RDO twice with a break of 4-5 weeks. Before performing the test questions examinees got motivating instructions. There was a video that recorded testee’s actions during the test. Videos were used to assess the emotional state. Rating emotional condition conducted by three experts according to the methodological recommendations of Paul Ekman. There were obtained the following results (mathematical processing - chi-square test, Wilcoxon T-criterion, multivariate analysis of variance). Based on them, it is possible to make several conclusions. First, examinees who experienced the emotion of fear in the first stage of researches, felt the same in the second stage. Second, examinees with high levels of situational anxiety experienced more emotion fear than examinees with low levels of situational anxiety. Thirdly, it is shown that men with high levels of situational anxiety allow fewer errors than women with high levels of situational anxiety, whereas men and women with low situational anxiety, situation is reversed. Also men who do not show emotion of fear do more errors than women who do not show emotion of fear, however, among men and women emote fear the situation is reversed. So, hypotheses about number of motor errors and manifestation of the emotion of fear were confirmed partially.
