The authors' purpose was to determine which form of therapeutic aid may influence academic approach and avoidance motivation in children with dyslexia. There were 165 children with dyslexia assessed with the use of "I and my school" questionnaire. The authors considered the children's previous therapeutic experience and on its basis they were divided into three groups. Children receiving systematic therapeutic treatment display a significantly higher level of academic approach motivation as compared to those from the two other groups. Those children also manifest a lower level of academic avoidance motivation compared to those receiving no form of specialist treatment. Girls, regardless of their therapeutic experience, demonstrate a higher level of approach motivation; boys, on the other hand, display a higher level of avoidance motivation. The study shows that the quality of provided therapeutic aid affects emotional-motivational sphere of children with dyslexia. Systematic therapeutic aid increases academic approach motivation and reduces avoidance motivation.
