Cross-Cultural Evaluation of the International Affective Picture System on an Indian Sample

The International Affective Picture System (IAPS) is widely used in emotion and attention research. Currently, there is neither a standard database of affective images for use in research with Indian population nor data on the way people from India respond to emotional pictures in terms of different dimensions. In the present study, we investigated whether self-reported Indian ratings are comparable to the original normative ratings (based on a North American sample) to evaluate its usability in Indian research context. The ratings were obtained from a sample of eighty Indian participants (age range?=?18 to 29 years, M _age?=?23.7, SD?=?2.67, 45 % females) on a stratified representative sample of 100 IAPS pictures. Similar to the normative data collected from the North American sample in the original IAPS database, the ratings were collected across three dimensions – valence (how pleasant/attractive or unpleasant/aversive), arousal (how calm or excited was the intensity of activation), and dominance (how controlling). Our results indicate similarities in valence ratings, but differences in arousal and dominance ratings between the Indian and the North American samples. The relationship between arousal and valence showed a similar (but less curved) boomerang shaped distribution seen with the North American sample. Unlike the North American sample, slopes were higher and intercepts were different for the Indian sample. However, the Indian sample also showed positivity offset and negative bias like the North American sample. These affective ratings show a fair amount of similarity but care is needed especially with arousal values in using these pictures for research with Indian population. While there are subtle differences in the relationship between different affective dimensions, there are also major similarities across cultures in affective judgments.
