EVENT-RELATED POTENTIALS IN GO/NOGO TEST IN GROUPS OF SUBJECTS WITH DIFFERENT LEVELS OF VERBAL CREATIVITY

Connection between creative thinking and attention was repeatedly discussed in literature. However, the question about organization of attention processes in individuals with different levels of creativity remains not sufficiently studied. In the present work, we compared the event-related potentials of the subgroups of subjects with different levels of creative abilities (verbal creativity, assessed by the test of distant associations of Mednik's (RAT) when performing the two-stimulus modification of the Go/NoGo test, which is a traditional tool for studying the mechanisms of attention. As a result, it was shown that subgroups of subjects with high and medium level of verbal creativity differ from subgroup of subjects with low level of verbal creativity by greater amplitude of the positive component P300. The direction of the identified differences between the subgroups is the same in the Go and NoGo trials, but significant differences between subgroups are found only in the NoGo trial. Also, the subgroup of subjects with a high level of creative abilities differs from the subgroup of subjects with a low level by a shorter reaction time in the Go trial. The data obtained suggest that the subgroups of subjects with different levels of verbal creativity differ by the mechanisms of attention associated with the processes of suppression of the response and, possibly, with the processes of involvement in action.
