GANTIVA, Carlos et al. Induction of Affective States with Pictures: Second Colombian Validation of the International Affective Pictures System (IAPS). rev.latinoam.psicol. [online]. 2019, vol.51, n.2, pp.176-195. ISSN 0120-0534.  https://doi.org/10.14349/rlp.2019.v51.n2.5.

The aim of this study was to validate a second group of images of the International Affective Pictures System (IAPS) in Colombian population, in order to increase the bank of images that can be used in research in the fields of emotion, attention and memory, among others. 240 pictures belonging to sets 15, 16, 17 and 18 of the IAPS were validated in a sample of 1222 participants from five cities in the country (Bogotá, Medellín, Cali, Barranquilla and Bucaramanga). To assess the emotional response to images in the valence, arousal and dominance dimensions, the Self-Assessment Manikin (SAM) was used. The results showed that the pictures were distributed as expected in the two-dimensional affective space composed of the valence and arousal dimensions. A positive emotional bias was identified in men and a negative emotional bias in women. The differences between regions and socioeconomic strata were presented only in arousal and dominance, not in valence. Together, the results suggest that these images can be used to induce affective states in the Colombian population in a controlled manner, which allows their use for the scientific and experimental study of different psychological processes, such as emotion, motivation and attention.
