Argentinian validation of set 19 of the International Affective Picture System (IAPS)

The  aim  of this  study was to report the Argentinian  norms of set 19 of the International Affective Picture System (IAPS) developed by Lang (Lang,  Bradley,  &  Cuthbert,  1997)  in  order  to  contribute  to  the  instrument’s cross-cultural  validation.  Participants  were  125  students  from  Universidad Nacional  de  San  Luis  (San  Luis  National  University)  (67%  women  and  33% men)  who  assessed  the  images  in  the  emotional dimensions  of  valence, arousal  and  dominance  through  the  Self-Assessment  Manikin  (SAM).  The results  showed  a  distribution  of  the  pictures  within  the affective  space  in  a boomerang  form,  which  is  similar  to  the  American  sample  (Lang,  Bradley,  & Cuthbert,  2008).  No  differences  in  the  emotional dimensions  of  valence  and arousal  were  identified,  but  they  were  found  in  dominance,  regarding  to  the data obtained by  Lang, Bradley and Cuthbert (2008). This study confirms that the  International  Affective  Picture  System  (IAPS)  induces  similar  affective states  in  different  populations  and  its  affective  stimulus  are  understood similarly by Argentinian and American subjects.
