To address experimentally the question of what kind of imformation may interfere with the process of cognitive tasks accomplishment and at which levels of information processing hierarchy such interference may take place.
The main research method was the laboratory experiment, also the quasi-experimental designs were used. Psychometric tools were used and developed as well. The process of the cognitive task accomplishment served as an object of study.
Empirical base of research
467 healthy volunteers of different age took part in ten experimental series.
Results of research
The following new results were obtained. It was shown that while different visual features of an object may be independently stored in the visual working memory, the object representation facilitates feature encoding and search (which implies that feature and object representation in the working memory is hierarchical). Another experiment demonstrated that attention guidance is influenced not by obejct brightness or contrast per se, but by the role of such visual feature in the task at hand. A study of visual attention in juniour schoolchildren revealed that, despite the inmaturity of their frontoparietal system which underlies top-down regulation of visual attention, children of 8-9 y.o. demonstrate top-down visual search guidance. No evidence was found in favour of hypothesis that low effect of the negative mood on working memory updating is due to using appraisal strategies of emotional control. Yet another study has shown that when in creativity tasks participants are asked to enlist and describe objects that share some functional property of the target object, but posess it to a lesser degree (and when naming this shared property aloud is not approved by the experimenter), originality of ideas on uncommon usage of the target object increases. We consider the obtained results as important for theoretical views of hierarchical layout of the cognitive task accomplishment in humans.
Level of implementation, recommendations on implementation or outcomes of the implementation of the results
The project was essentially fundamental and did not imply any direct implementation of its results.
