Portuguese category norms for children

This study presents Portuguese category norms for children of three different age groups: preschoolers (3- to
4-year-olds), second graders (7- to 8-year-olds), and preadolescents (11- to 12-year-olds). Three hundred Portuguese
children (100 in each group) completed an exemplar-generation task. Preschoolers generated exemplars
for 13 categories, second graders generated exemplars for 17 categories, and preadolescents generated exemplars
for 21 categories. For each group, responses within each category were organized according to frequency of
production in order to derive exemplar-production norms for sets of tested categories. The results also included
information about the number of responses and exemplars, idiosyncratic and inappropriate responses, and commonality
and diversity indexes for all the categories. A comparison of these children’s norms with the Portuguese
adult norms was also presented. The full set of norms may be downloaded from www.psychonomic.org/archive.
