The study found that individual differences in the average gaze time in the first round of reading were associated with resting function connections

Eye movement is one of the most important behaviors in reading.
that there are individual differences in eye movement in reading, but the academic community is not clear about its neural association.
li Xingshan, a researcher at the Key Laboratory of Behavioral Science of the Chinese Academy of Sciences, studied the problem and used eye tracking and resting magnetic resonance imaging to explore the correlation between the first round average gaze time of an individual in chapter reading and the connection of individual resting state function.
first-round average gaze time refers to the average length of time a reader has all gaze in the first reading and is an important indicator of the difference in eye movement in an individual's reading.
has found that first-round gaze is associated with at least four cognitive components, including early visual processing, word recognition, attention shifts, and eye movement control.
resting-state functional connectivity refers to changes in blood oxygen signals in different brain intervals in a non-tasking state.
studies have shown that there is a strong correlation between individual differences in rest state functional connections and individual differences in brain and behavioral indicators in task state.
researchers collected data on 49 subjects' resting-state functional magnetic resonance (resting-state fMRI) and recorded their eye movements during a discourse reading task.
Based on existing reading eye movement models (e.g. CRM models) and existing research in the field of cognitive neuroscience, the researchers defined the primary visual cortical cortical network, visual word form area, and eye movement control network/back-side attention network (including double-sided frontal eye movement area, double-sided top-down groove, and auxiliary eye movement area) as interest areas to examine the relationship between resting function connections and the first round of average gaze time.
study found that the resting state functional connections between the two parties in the three interest zones were positively related to the first round average gaze time, and that the resting state function connections in the three interest zones generally explained about a quarter of the variation in the individual differences in the first round of average gaze time, suggesting a strong correlation between the two.
researchers believe the results suggest that the length of the gaze may have some shaping effect on the resting functional connections in the relevant brain regions.
Specifically, this is mainly related to two known mechanisms: the prevalence of the time-on-task effect in the relevant brain regions of reading and eye movement control, i.e., the longer the gaze, the stronger the induced brain activation;
the researchers speculated that longer first-round average gaze time was more brain-activated in the relevant brain region, and that Heb learning had a stronger effect on resting-state functional connections, leading to a positive correlation between the two individually.
