Special pedagogy belongs to pedagogical disciplines. It is defined as a science branch that studies regularities of training and education of individuals who are disadvantaged comparing to the major population at mental, sensory, somatic area; communication skills; psycho-social area; learning disorders and accelerated talent. Nowadays especially terminological disunity is in the middle of attention at training-educational area; but also at legislative area, pedagogues, parents, educational advisors and also special pedagogues themselves. Special practice forces specialists and also special pedagogues to gain as much knowledge about terminology as possible not only here but also abroad with purpose of its unity. Objective attitude to a personality with disability or disorder can be only created as a result of complex attitude. Within this attitude the terminology makes a serious part. To understand the difficult issue regarding the terminology at special pedagogy a scientific monograph which had been created by many specialists not only from Slovakia but also from abroad can definitely help. We assume that not only students of special pedagogy but also teachers from practice, wide pedagogical and non-pedagogical public and all of those who concern about this issue (including special employees of various resorts) will find answers on many difficult questions about terminology at special monograph. We also believe that it will enrich the theory of special pedagogy as well in an important way. Excerpt from the Introduction
