The planned contrasts in Experiments 2, 3, 5, and 6 involve bare versus definite-marked NPs, and this means that the critical regions will differ by three character lengths (a white space and the two characters – the definiteness marker ko – on the definite marked NP). One question that arises is: is a word-length correction necessary? The assumption in the psycholinguistic literature is that word length does significantly affect reading time (see, e.g., (Trueswell et al., 1994)).
