The production and interpretation of pronouns involves the identification of a mental referent and, in connected speech or text, a discourse antecedent. One of the few overt signals of the relationship between a pronoun and its antecedent is agreement in features such as number and grammatical gender. To examine how speakers create these signals, two experiments tested conceptual, lexical, and morphophonological accounts of pronoun production in Dutch. The experiments employed sentence completion and continuation tasks with materials containing noun phrases that conflicted or agreed in grammatical gender. The noun phrases served as the antecedents for demonstrative pronouns (in Experiment 1) and relative pronouns (in Experiment 2) that required gender marking. Gender errors were used to assess the nature of the processes that established the link between pronouns and antecedents. There were more gender errors when candidate antecedents conflicted in grammatical gender, counter to the predictions of a pure conceptual hypothesis. Gender marking on candidate antecedents did not change the magnitude of this interference effect, counter to the predictions of an overt-morphology hypothesis. Mirroring previous findings about pronoun comprehension, the results suggest that speakers of gender-marking languages call on specific linguistic information about antecedents in order to select pronouns and that the information consists of specifications of grammatical gender associated with the lemmas of words. © 1999 Academic Press Key Words: language production; pronouns; grammatical agreement.Pronouns can be found in all languages of the world. In English and Dutch they are among the most commonly used words in print (Baayen, Piepenbrock, & van Rijn, 1993) and are probably even more frequent in speech. They are fundamental to both the structure and the function of language. They are nonetheless far from simple in their conditions of use, either linguistically or cognitively, in either comprehension or production. One testimonial to their cognitive complexity comes from language acquisition, where children's problems with pronouns may persist well past the point at which the use of common nouns is firmly established (Clark, 1978;Clark & Sengul, 1978).For adult listeners, the challenges of interpreting pronouns have to do with identifying pronominal referents and antecedents from the minimal feature specifications that pronouns afford. In English, these features include little beyond number, natural gender, and animacy. Some languages add more features to the set, notably grammatical gender, but because the sparse meaning specifications of pronouns are Order of authorship is arbitrary.
