Воздействие транскраниальной стимуляции переменным током на понимание предложений: роль альфа-ритма в поверхностной обработке

How people comprehend language is still a controversial issue among researchers, although there have recently been an increasingly greater number of discoveries in the field of neurobiology of language and language processing. As sentence information is critical to successful language comprehension (Fodor, Bever, & Garrett, 1974; Frazier & Rayner, 1990), in this study we would like to focus on such domain of language as syntax. The aim of this study is to attempt to modulate the alpha oscillation band via tACS in order to discover its role in sentence processing, more precisely, whether this oscillation is involved in top-down semantic prediction, driving “good-enough” processing. In other words, we would like to assess whether it is possible to worsen the performance on sentence comprehension task by stimulating the particular oscillatory frequency. Our predictions are that such stimulation would lead to more mistakes in sentence comprehension task due to greater reliance on semantics, meaning top-down prediction, rather than on bottom-up information, driven by syntactic structure itself.
