Stimuli Selection Criteria for the Experiment “Visual Perception of Imitative Words in Native and Non-Native Language by the Method Lexical Decision”

Introduction. The present article is aiming to describe the procedure of stimuli selection for the psycho-semantic experiment on visual perception of imitative words in native (Russian) and non-native language (English). The methodology of the experiment is predominantly based on the implementation of the “lexical decision” method. Thus, the aim of the article is to verify the procedure of and to define clear-cut criteria for the material selection. In particular, we introduce indicating de-iconization stage of imitative words as an important criterion for data pre-selection. De-iconization is a gradual loss of an iconic sound-sense link in an imitative word due to the parallel impact of regular sound changes and semantic shifts.Methodology and sources. The research methodology is based on the works ofS. V. Voronin who is the founder of phonosemantics as a linguistic discipline inRussia, as well as on works of his followers (including a co-author of this paper, M. A. Flaksman). The article is also based on the methodology of research on phonotactics. The authors also use psycho-semantic methods such as the method of lexical decision. The main sources of stimuli selection are The Russia Etymological Dictionary by M. Vasmer, The Oxford English Dictionary, the frequency dictionaries by O. N. Liashevskaya and S. A. Sharov. The classification of imitative words according to their de-iconization stages was done by the method of the diachronic evaluation of the imitative lexicon.Results and discussion. As a result of a rigorous selection procedure described in the article the authors arrived on 128 stimuli (an even number (64 + 64) of words and quasiwords). The quasi-words are coined according to phonotactic rules and made according to the same pattern as the corresponding words. The group of real words is constituted of two sub-groups: 32 imitative words and 32 non-imitative words. The words from these two subgroups are homomorphous – they have the same number of syllables, frequency and belong to the same parts of speech. Imitative words include onomatopoeic and soundsymbolic words of different sub-classes and de-iconization stages. The combination of the material selection methods discussed in this paper (especially, the introduction of the distinction of imitative words according to their de-iconization stage) is aiming at facilitating the experiment procedure as well as eliminating the chance factors.Conclusion. The stimuli selection for the psycholinguistic experiment based on the procedure introduced in this paper allows to establish the existing patterns of the systematic function of human brain in the process of visual perception of imitative words on different de-iconization stages.
