The acquisition of two types of anaphora, reflexive and non-reflexive personal pronouns, was investigated. It was hypothesized that the two types of anaphora are acquired at different developmental stages. The three experiments involved Dutch children of age 6 and 7 and adults. Interpretations of sentences containing third person reflexive pronouns, sentences containing non-reflexive third person pronouns, and series of randomly arranged sentences containing either type of pronoun were tested. The 6-year-olds were unable to correctly interpret anaphoric pronouns when both types of pronouns were presented. The 7-year-olds were able to interpret reflexive pronouns but not the non-reflexive pronouns. The results provide some evidence that the discovery of the relationship between a reflexive pronoun and its antecedent is easier than that of a non-reflexive anaphoric pronoun and its antecedent.
