The book addresses the study of reading mechanisms and visual perception using the method of eye-tracking. The authors conduct their research in the Laboratory for Cognitive Studies of Saint Petersburg State University that was the first in Russia to utilize eye-tracking in experimental studies of language more than 15 years ago. Psycholinguistic experiments aimed at analyzing reading in Russian are described; a systematic description of factors which influence reading process at different stages and linguistic levels from a single letter to a coherent text is provided. The mechanisms of separate graphemes recognition, activation and competition processes in word recognition, contextual integration processes, syntactic parsing, and anaphora resolution in eye-tracking experiments are described. The influence of the text type on its processing is demonstrated, the advantages and disadvantages of the infographics compared to verbal text are described, the relationship between visual perception of images and their verbalization is discussed. The significant role of context is highlighted: on the one hand, it helps the reader to anticipate new information, and on the other hand, it enables different multiple interpretations of a sentence or text. In the book a virtual assistant — Schroedinger’s cat — is used as a model of a subject who processes and transmits information. The book will appeal to linguists and cognitive psychologists who use eye-tracking in their research, as well as for the wide range of those who are interested in objective methods of studying language processing and human behavior.
The article analyses the implementation of the convergent approach on the example of studying mechanisms for selecting meanings in situations of ambiguity by the methods of cognitive psychology, linguistics, and neurophysiology. We describe the rationale of the problem statement for convergent research and the necessary prerequisites for implementing an interdisciplinary approach. We consider that in case of ambiguity resolution the special mechanism provides the choice: which meaning would enter consciousness (and he / she becomes aware of it), and which — is rejected. That being said, the unselected meaning is not simply ignored, but rather actively suppressed. Such suppression results in its negative after-effect; more precisely the difficulty of retrieving the previously suppressed information. In our research the fMRI method made it possible to study brain mechanisms involved in the selection of a word’s meaning while behavioral methods allowed for the study of the after-effects of this selection. Thanks to the mutual development of a design by representatives of cognitive psychology, linguistics, and neurophysiology, it is possible to overcome the considerable methodological incompatibility of those methods. The results discovered in behavioral psychological research demonstrated negative after-effects of the rejected meaning. However, without the neurophysiological approach the data would remain unclear due to two possible interpretations. As a result of the analysis of the brain functional activity, the decrease in the localized hippocampal activity during the selection of meaning for an ambiguous word was revealed. This supports the hypothesis that the involvement of suppression processes in ambiguity resolution exists. Our work once again illustrates how important forethought and a philosophical foundation of the question posed is for interdisciplinary research regarding the processes of brain mechanisms. Unification of the efforts of representatives of various sciences provides qualitative new knowledge, which would not be possible to achieve in a different experimental situation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
