ABSTRACT
In the last years, many experimental studies have shown that morphological relationships among words affect subjects’ performance in tasks, such as lexical decision or tachistoschopic recognition, which are considered to require lexical access. A variety of models have proposed that morphological relationships are represented within some component of the lexical processing system. More specifically, some models assume that morphological relatedness acts as a principle of organisation among lexical entries, that is, within the component in which lexical representations are permanently stored (e.g. Burani & Caramazza, 1987; Caramazza, Laudanna, & Romani, 1988; Jarvella & Meijers, 1983; Lukatela, Gligorijevic, & Kostic, 1980; Taft & Forster, 1975; Tyler, Behrens, Cobb, & Marslen-Wilson, 1990).
