Abstract:
Sakai R, Koike Y, Saito K, Matsunaga T, Shimada Y, Miyakoshi N. Aphasia testing (auditory comprehension domain) using a new eye-tracking system in healthy participants. Jpn J Compr Rehabil Sci 2022; 13: 31-35.
Objective:
We administered a conventional pointing-method test with eye-tracking to evaluate items associated with auditory comprehension and examined the concordance between the obtained results.
Methods:
The enrolled participants were 10 healthy volunteers. We performed tests after extracting auditory comprehension items from the SLTA, the WAB, and the Supplementary tests for the SLTA using the eye-tracking system and the pointing method.
Results:
The mean test duration was 9 min 51 s ± 1 min 41 s (mean ± SD), and the percentage of correct answers was 100% and in perfect agreement for the pointing method and the eye-tracking system. The mean response time was 0.96 ± 0.36 s for the pointing method and -0.39 ± 0.21 s for the eye-tracking system. Hence, the latter was faster than the former, and examinees completed their responses before listening to the end of the questions.
Conclusion:
The new eye-tracking system makes it possible to perform aphasia tests (auditory comprehension items) comparable to the conventional pointing method.
