Sentence-final word completion norms for European Portuguese children and adolescents.

This study presents a set of sentence contexts and their cloze probabilities for European Portuguese children and adolescents. Seventy-three sentence contexts (35 low- and 38 high-constraint sentence stems) were presented to 90 children and 102 adolescents. Participants were asked to complete the sentence contexts with the first word that came to mind. For each sentence context, responses were listed and cloze probabilities of the words that were chosen to complete the sentence context were computed. Additionally, idiosyncratic and invalid responses (structural and semantic errors) were analyzed. A high degree of consistency in responses among the two age samples (children and adolescents) was found, along with a decrease of idiosyncratic and invalid responses in older participants. These results shed light on age-related changes in the effects of linguistic context on word production, and also in knowledge's representation.
