## 3 Experimental Results
### Behavioral Data Analysis  
Descriptive statistics for behavioral performance are shown in Table 1. In the non-fatigue state, the mean RT for the baseline task without interruptions was 692.09 \(\pm\) 114.10 ms, while the mean RT for the baseline task with interruptions was 813.81 \(\pm\) 230.64 ms. A significant difference in RT was observed between the two baseline tasks (\(F\)(1, 83) = 8.302, \(p\) = 0.005, \(\eta_{p}^{2}\) = 0.091). For ACC, the mean ACC for the baseline task without interruptions was 94.1 \(\pm\) 0.5%, compared to 92.8 \(\pm\) 2.5% for the baseline task with interruptions. However, no significant difference in ACC was found between the two baseline tasks (\(F\)(1, 83) = 2348, \(p\) = 0.131). Under fatigue conditions, the mean RT for the non-interrupted baseline task was 751.16 \(\pm\) 61.11 ms, while that for the interrupted baseline task was 889.38 \(\pm\) 227.01 ms, with a significant difference between the two tasks (\(F\)(1, 83) = 9.234, \(p\) = 0.003, \(\eta_{p}^{2}\) = 0.10). The mean ACC for the non-interrupted baseline task was 92.3 \(\pm\) 2.8%, compared to 90.0 \(\pm\) 1.6% for the interrupted baseline task, also showing a significant difference (\(F\)(2, 82) = 17.92, \(p\) < 0.01, \(\eta_{p}^{2}\) = 0.30). \begin{table}

Table 1: Descriptive statistics analysis results of behavioral performance under different conditions (mean \(\pm\) standard deviation). A 2(fatigued, non-fatigued) \(\times\) 3(simple task interruption, complex task interruption, pause interruption) \(\times\) 2(pre-interruption trials, recovery trials) repeated-measures ANOVA was conducted. The results (see Table 2) revealed a significant interaction between fatigue state and interruption type for RT (\(F\)(1, 48) = 5.389, \(p\) = 0.002, \(\eta_{p}^{2}\) = 0.147). Significant interactions were also found between fatigue state and trial type, as well as between interruption type and trial type. Further analysis showed that, in the non-fatigued state, RTs differed significantly in the recovery trials (\(F\)(1, 28) = 4.829, \(p\) = 0.038, \(\eta_{p}^{2}\) = 0.147). Significant differences in RTs were observed in recovery trials across the three interruption types in the fatigued state. (\(F\)(1, 28) = 3.449, \(p\) = 0.004, \(\eta_{p}^{2}\) = 0.11), as well as in ACC (\(F\)(1, 28) = 20.255, \(p\) < 0.01, \(\eta_{p}^{2}\) = 0.420). However, only ACC (\(F\)(1, 48) = 9.839, \(p\) = 0.003, \(\eta_{p}^{2}\) = 0.057) showed significant differences in the pre-interruption trials.
