Experimental design considerations in studies of event-related potentials to word and nonword stimuli.
A recent paper by Katayama and associates (1987) reported differences in late negative components of the event-related potentials to non-words versus semantically deviant words in a randomized sequence. This comparison was confounded with differences in response requirements between the two stimulus classes.
