摘要：The research aims to reveal the typical expressions of cognitive dissonance and consonance among the primary-school children by their argumentations upon their deed. The relevance of the research stems from the applicability of the study of the phenomena of dissonance and consonance,which inherently emerge in the sphere of argumentation among the children who study how to play chess. Cognitive dissonance and consonance in the sphere of argumentation in the course of the game of chess are gradually transforming both into the respective reference points – relevant to the situation given,and into the emotional and behavioural manifestations – either adequately or inadequately expressed and,by the logical and inner conflict,are observed as the result of juxtaposition of the realms of emotions and logic. The present research evidences that,in the case of similar chess skills,the manifestation of cognitive dissonance,and the own argumentation as well are detectable within the domain of extroversion – emotional instability. Such children,even more than the introverts,need the school psychologist’s support. The cognitive consonance is typical of those of the children involved who are ready to gain new experience and appear to be more positively charged towards their rivals or opponents..
