### Differences within Groups in Neuro-World and Conventional Cognitive Training Programs  
The differences within groups in the _Neuro-World_ cognitive training program are shown in Table 5. The average score (M = 65.4) of post-intervention in this group showed an average of 3.3 points higher than the average score (M = 62.1) of preintervention, exhibiting a statistical significance between these scores (\(F\) = 31.176, \(p\) < 0.05). The differences in sub-items in the groups in the _Neuro-World_ cognitive training program are shown in Table 6. The score decreased by 1.2 points from 20.7 to 19.5 in the verbal understanding section, and by 1 point from 21.8 to 20.8 in the perceptual reasoning section. In contrast, the working memory section shows an increase by 3.2 points from 10.0 to 13.2, and the processing speed section shows an increase by 2.5 points from 10.5 to 13.0. In other words, a statistically significant difference was observed between the pre-and post-scores of verbal understanding, working memory, and processing speed (\(F\) = 29.207, \(F\) = 10.909, \(p\) < 0.05). The differences within groups in the conventional cognitive training programs are shown in Table 7. The post-intervention score of the conventional cognitive training programs group was 0.2 points lower than the pre-intervention score, was not significant (\(F\) = 0.041, \(p\) < 0.5). The differences in sub-items within a group in the conventional cognitive training programs are shown in Table 8. As shown, the scores decreased by 0.3 points from 19.8 to 19.5 in the verbal understanding section but increased by 0.2 points from 18.9 to 19.1 in the perceptual reasoning section and by 0.1 points from 10.9 to 11.0 in the working \begin{table}
