El presente estudio tiene como objetivo validar un conjunto de imágenes del International Affective Picture System (IAPS) de Lang, Bradley y Cuthbert (2005) -un instrumento ampliamente utilizado en investigación afectiva-- en una muestra chilena, así como comparar sus resultados con aquellos obtenidos en el estudio estadounidense, en vistas a contribuir a su validación intercultural. Se utilizó una muestra de 135 estudiantes universitarios, quienes evaluaron 188 imágenes en las dimensiones de valencia y arousal, de acuerdo con instrucciones estándar. Los resultados muestran la organización esperada de la afectividad, con variaciones entre sexos en la valoración de valencia, y diferencias entre países en la dimensión de arousal. Se concluye que la adaptación chilena del IAPS es consistente con los estudios previos, lo cual añade evidencia a favor de su validez intercultural. [ABSTRACT FROM AUTHOR]

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. [ABSTRACT FROM AUTHOR]
