Objective: We administered a conventional pointingmethod
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.
