Abstract: The purpose of the research presented in the article is to determine the possibility of changing the success of solving tasks of a convergent type by junior schoolchildren through varying the external motivational attitude. Within the framework of the research convergent tasks mean the tasks that have only one correct decision. In her research Gavrilova has used two types of tasks: tasks aimed at abstract-logical thinking and tasks aimed at spatial thinking. The author of the article discusses the results of an empirical study of the success of solving convergent tasks by junior schoolchildren depending on three different motivational attitudes: neutral, competitive and negative, held in 2016-2017 on the basis of one of Moscow's educational establishments. The main method of the study was an experiment. All in all, 126 second-grade students participated in the study. During the analysis of the results obtained, statistically significant differences were found both for the tasks of the abstract-logical block and for the spatial block. In particular, the author has revealed tendencies to decrease the success of solving logical tasks under competitive attitudes. In addition, significant differences in the success of solving the tasks of the two blocks mentioned were found - as the study showed, contemporary second-grade school students are much less successful in solving spatial thinking tasks. At the same time, these are the tasks of the spatial type that are more susceptible to the change of the attitude.
