Outline of Final Research Achievements

In term of character stimuli, we proved that native Japanese readers depend heavily on visual information and scarcely on phonological information in processing words and that their performance would be affected by the meanings of characters composing words. We then suggested that we should consider native readers' processing characteristics in choosing word stimuli for such experiments as lexical decision or memory span experiments. In terms of experimental designs, we found that the intervals of two stimuli with within-block designs would distort temporal uncertainty and cause response time bias. We, therefore, recommended the use of between-block designs as well as catch trials skipping the second stimuli.
