| Abstract: | Lee (1999) argued that there would be two possible confounding variables in the word length effect. This study attempted to control those two variables. A possible confounding variable in the word-length effect is the neighborhood size. A shortword usually has more neighbors than a long word.Another confounding variable is different perceptual availability between inside and outside letters in a long word. Inside letters are easier to perceive than outside letters. Controlling of these two confounding variables in the two experiments eliminated the wordlength effect. |
