This diploma thesis deals with the power of language and the relation between language and thought, perception and experience. The topic is viewed through the "Respektovat a být respektován" (To Respect and To Be Respected) educational method. The main assumption of this method is that the way the parent communicates with the child affects educational success as well as the behaviour of the child and the values and attitude he or she will have as an adult. This premise is empirically tested by interviews with parents and observations in families, which show how the specific way of communication (which is based on particular grammatical and pragmatic rules) influences the behaviour and experience of both the child and the parent.
