However, few studies have directly compared processing of stimuli comprising different types of morphemes, particularly bound and free morphemes. Methods: Eighty fluently reading young adults participated in a lexical decision task with word…

Previous studies used the ex-Gaussian fitting technique to examine the distribution of word frequency effects in English sentence reading and lexical decision tasks. It was found that word frequency influences reaction times and eye fixation durations by both shifting the distribution to the right and increasing the skew for the low-frequency…
