| Research Abstract |
To elucidate factors affecting reading performance of presbyopic middle-aged persons, we measured reading speed(presentation duration threshold and response time) in a reading-aloud task in rapid serial visual presentation and a non-word detection task in visual search. We manipulated letter size, luminance contrast, viewing distance, native-nonnative words, and number of strokes. The results showed that each of these factors affects reading performance in presbyopia, and that presbyopic participants show larger interactions among these factors than younger ones : Their reading speed is markedly slowed down when reading small letters in low luminance contrast at a near distance.
