PMID 34987349WHAT IT FOUND
The Korean version of the Motor-free Visual Perception Test-4 is reliable and valid for healthy Koreans aged 10 to 79.
It correlates well with another visual perception test and shows no sex differences, though scores decline with age.
Key findings
01The Korean version showed excellent internal consistency and test-retest reliability.
02Scores on the Korean test correlated significantly with the motor-reduced section of the Korean Developmental Test of Visual Perception.
03Visual perception scores did not differ between men and women, but decreased significantly with age.

What it does not show
The study only included healthy people, so it does not show how the test performs in those with disabilities or visual deficits. Participants were recruited from only four regions of South Korea, so results may not apply to the whole country. Standardized scores were not created, so you can only compare raw scores. The test was only validated against another measure in adolescents (11-19 years), leaving concurrent validity unproven for adults over 20.
Declared interests
The authors received permission from the test publisher to translate the MVPT-4 for research purposes only. The study was funded by Wonkwang University.
The easy way to misread this
Do not assume this Korean version is ready for clinical diagnosis of pathology. It was tested only on healthy people, lacks standardized norms (only raw scores), and its validity for adults over 20 has not been confirmed against a gold-standard test.
