While working at his thesis, N.Dmitrieva demonstrated a valuable quality for all the fields a linguist can work in, namely an ability to plan one’s time and effort. She conducted the experiments 6 months before the viva date, which gave her enough time for thinking over and analyzing the data, and finding the most appropriate form of presenting the findings. As a result of her immaculate planning she submitted an excellent research paper that adequately shows the outcomes of a series of psychological experiments with a large number of participants. It has to be emphasized that in order to fulfil the research successfully the student had to acquire some mathematical skills on her own, as the study of the probability theory is beyond the traditional linguistic curriculum.
