Adding support to cross-cultural emotional assessment: Validation of the international affective picture system in a chilean sample

Abstract

The present study aimed to obtain a valid set of images of the International Affective Picture System (Lang, Bradley & Cuthbert, 2005) -a widely used instrumentation in emotion research- in a Chilean sample, as well as comparing these results with those obtained from the US study in order to con tribute to its cross-cultural validation. A sample of 135 college students assessed 188 pictures according to standard instructions in valence and arousal dimensions. The results showed the expected organization of affectivity, with variations between sex in valence judgments, and differences between countries in the arousal dimension. It is concluded that the Chilean adaptation of the IAPS is consistent with the previous evidence, adding support to it cross-cultural validity.
