Picture-naming norms for Canadian French: name agreement, familiarity, visual complexity, and age of acquisition.

The present study provides Canadian French normative data for 388 line drawings from the European Picture Pool for Oral Naming (Protocole européen de dénomination orale d'images; PEDOI; Kremin et al., 2003). One hundred eighty subjects were equally distributed for age group (18-39,40-59, 60-85), educational level (low, high), and sex. They rated pictures of objects on age of acquisition, name agreement, familiarity, and visual complexity. Syllable length and word frequency were also taken into account. The present study suggests that age of acquisition and name agreement show significant age-related differences. These results show that unequivocal interpretation of age-related differences can be made when age-appropriate norms are used.
