This study investigated age-related changes of cognitive function in Korean adults using the Korean-Developmental Test of Visual Percep-tion-2 (K-DTVP-2) and the Visual Motor Integration-3rd Revision (VMI-3R) test, and determined the main factors influencing VP and VMI in older adults. For this research, 139 adults for the K-DTVP-2 and 192 adults for the VMI-3R, from a total of 283 participants, were randomly and separately recruited in province, Korea. The present study showed that the mean score of the K-DTVP-2 and VMI-3R in 10-yr age incre-ments significantly decreased as age increased (K-DTVP-2, F=41.120, P<0.001; VMI-3R, F=16.583, P<0.001). The mean score of the VMI-3R and K-DTVP-2 were significantly decreased in participants in their 50s compared to those in their 20s (P<0.05). Age (t=-9.130, P<0.001), gen-der (t=3.029, P=0.003), and the presence of diseases (t=-2.504, P= 0.013) were the significant factors affecting K-DTVP-2 score. On the oth-er hand, age (t=-6.300, P<0.001) was the only significant factor affect-ing VMI-3R score. K-DTVP-2 score (Standardized β=-0.611) decreased more sensitively with aging than VMI-3R (Standardized β=-0.467). The two measurements had a significant positive correlation (r =0.855, P< 0.001). In conclusion, it can be suggested that VP and VMI should be regularly checked from an individual’s 50s, which is a critical period for detecting cognitive decline by aging. Both the K-DTVP-2 and VMI-3R could be used for determining the level of cognitive deficit by aging.
