The aim of the present study is to explore the representation and processin
g of inflectional morphology in Spanish. Experiment 1 compared the access t
ime Sor words from the same base morpheme contrasted by the surface frequen
cy of the masculine and feminine form, i.e., masculine-dominant items and f
eminine-dominant items. The results showed a surface frequency effect in bo
th types of items. Experiment 2 compared the access time for masculine Word
s having the same surface frequency but differing in their summed frequency
(masculine plus feminine forms), the results showing no significant effect
of this parameter Finally, experiment 3 compared the access time for, word
s from the same stem and contrasting by the surface frequencies for the sin
gular and plural forms, i.e., singular-dominant and plural-dominant words.
A clear frequency effect was observed for the singular-dominant words but n
ot for plural-dominant ones. These results suggest that gender information
is stored in the corresponding lexical entry and accessed from the full wor
d form whereas the information about number is accessed from the stem corre
sponding to the singular form.
