Expanded norms for 400 experimental pictures in an argentinean spanish speaking population

The study of the cognitive processes in the production of language demands careful selection of stimuli and requires normative databases. The main goal of the present research was to collect normative data for the set of 400 figures taken from Cycowicz, Friedman, Rothstein, and Snodgrass (1997; including the 260 figures of Snodgrass {\&} Vanderwart, 1980) using a sample of native Argentinean Spanish speakers. The pictures have been standardized on the following variables: name agreement, image agreement, familiarity, visual complexity, image variability, age of acquisition, and word association. The obtained norms were compared with the normative data of other studies in Spanish, English, and French. This comparison highlights the variability of some of the measures (e.g., name agreement in naming and verbal association) across the different studies and confirms the necessity of elaborating specific norms that are adapted to the studied population's linguistic and sociocultural context.
