### Comparison of Average Fixation Duration According to Age, Reading Conditions, and Text Types  
A main effect of age on average fixation duration (AFD) was observed (\(F\)(5, 545) = 14.976, \(p\) < 0.001), with a trend towards shorter AFD among older students compared to younger students (see Figure 1). According to the subsequent [PERSON] post hoc test, in the R condition, age-related differences reached statistical significance only when participants were reading fictional text. Significant differences in AFD were observed between grade 1 and grade 4 (\(p\) < 0.001), grade 1 and grade 5 (\(p\) < 0.001), grade 1 and grade 6 (\(p\) < 0.001), as well as between grade 2 and grade 5 (\(p\) = 0.005) and grade 2 and grade 6 (\(p\) = 0.047). Within the AR condition, a significant difference in AFD between grade 1 and grade 3 was observed while reading fictional text (\(p\) = 0.041). When engaging with non-fictional text in the AR condition, significant differences in AFD emerged between grade 1 and grade 4 (\(p\) < 0.001), grade 1 and grade 5 (\(p\) < 0.001), and grade 1 and grade 6 (\(p\) = 0.013).  
The results showed no significant main effects for reading condition (\(F\)(1, 545) = 0.313, \(p\) = 0.576) and text type (\(F\)(1, 545) = 0.805, \(p\) = 0.370). Additionally, no significant interactions
