ARTICLE HIGHLIGHTS
Research background

Neglect has different symptoms depending on the type. Among the different types, egocentric neglect (EN) and allocentric neglect (AN) can be differentiated by the apple cancellation test.

Research motivation

Many countries have standardized the apple cancellation test and used it in their own countries. However, South Korea has not yet standardized the test.

Research objectives

In this study, we aimed to standardize the apple cancellation test for South Korea.

Research methods

We conducted the apple cancellation test on 223 normal people (20-80 years old) and wanted to present the cutoff score according to age.

Research results

The cutoff scores for diagnosing EN and AN were presented by age. At the same time, we also presented the time requirements for the test by age and education level.

Research conclusions

We have completed the standardization of the apple cancellation test for South Korea. We look forward to using it in more studies.

Research perspectives

It would be meaningful to standardize the various tests for each country to ensure accurate testing.
