Исследования несимволического чувства числа с помощью айтрекинга: систематический обзор

Introduction. The processing of quantitative information is one of the basic processes that ensures successful interaction with the environment. In one form or another, this ability is found in a large number of biological species. In humans, the specifics of processing quantitative information in different formats are analysed in experimental and correlational studies using various methods and approaches, including eye tracking. Eye tracking makes it possible to follow the mechanisms of the formation of the mental representation of quantity and to evaluate the connection of the non-symbolic "sense of number" with the systems of representation of other visual parameters, such as the size of objects. Methods. This paper presents a systematic review of eye tracking studies of non-symbolic numerosity estimation published from 2008 to 2023. A search of Scopus, Web of Science and PubMed databases identified 13 studies. Results and Discussion. The research questions, the characteristics of the tasks and stimulus materials used, the characteristics of the sample and the results obtained have been systematised. This review highlights the mechanisms of operation of the numerosity representation system and the characteristics of conducting eye-tracking studies to investigate them.
