  FIGURE 1. The Flanker task paradigm. The full Flanker task consists of 4 blocks of 240 trials (120 incongruent, 120 congruent). The stimuli are randomly presented in the center of the computer screen. Each block has a 10 s rest period.

  FIGURE 2. Emitter and probe configuration for functional near infrared spectroscopy (fNIRS). The fNIRS system was attached to the prefrontal area. The center of the probe matrix was placed on Fpz (International 10–20 system).

  FIGURE 4. The changing trend of immersion scores in the two groups. The immersion scores of the YoMed group and Control group increased with the extension of the intervention days. The immersion scores evidenced a statistically significant increase in the YoMed group. ∗∗p < 0.001, with very significant difference, ns p > 0.05, no significant difference, and the data is expressed as mean ± standard error.

  FIGURE 5. The cerebral oxy-Hb concentration in the prefrontal cortex (PFC) between YoMed and Control groups at pre- and post-test. The cerebral oxy-Hb concentration in the prefrontal cortex for the YoMed group at post-test was significantly higher than those at pre-test. While there was no statistically significant change in the Control group. ∗p < 0.05, with significant difference. Data are expressed as mean ± standard error.
