Normative Values of the International Affective Picture System in Mexicans: Differences between USA, Colombia and Mexico. Univ. Psychol. [online]. 2018, vol.17, n.2, pp.30-38.

The International Affective Picture System (IAPS) is an instrument to the study of emotions and motivation with a high empirical evidence and versatility. However, it has not been tested in Mexican population, for that reason the aim of this study was to determine the normative values of valence, arousal and dominance for the IAPS sets of pictures 13, 14, 19 and 20 in Mexican population. Participants were 408 students who assessed 238 images of the IAPS through the Self-Assessment Manikin (SAM). The results showed that the pictures distribution on the two-dimensional affective space (valence-arousal); take a boomerang form, which is consistent with the findings in other populations. Nevertheless, in the Mexican population there was a stronger relationship between appetitive valence and arousal than the one observe in aversive valence and arousal. In conclusion the normative values in the IAPS sets of pictures 13, 14, 19 and 20 can be used in the study of emotions in Mexican people.
