MINA, Leonel; BAKKER, Liliana; RUBIALES, Josefina  and  GONZALEZ, Rocío. A Validation Study of The International Affective Picture System in Children and Adolescents in Argentina. Rev. psicol. [online]. 2017, vol.26, n.2, pp.76-91. ISSN 0716-8039.

The aim of the study was to analyze the psychometric behavior of the set of images for children and adolescents of the International Affective Picture System. The sample consisted of 141 children and adolescents between 7 and 14 years old, divided into three age ranges, that evaluated 60 images in the valence and arousal dimensions. The results showed a low activation for images considered as pleasant and high activation with a negative strong correlation for images considered as unpleasant. The distribution of the images in the affective space showed a greater dispersion and less inclination activation for pleasant pictures, compared to unpleasant. The valence dimension consists in the main axis that emotions are organized, and it is related to the process of human adaptation and evolution, compared with the arousal dimension that would be more influenced by learning and sociocultural factors. The distribution of affective stimuli in two-dimensional space reflects the organization of emotions for children and adolescents in Argentina, demonstrating that IAPS may be a reliable instrument to assess emotions in this population.
