This paper reports studies on adaptation of a measure of an out-group infrahumanization effect introduced by Viki (Viki et al., 2006), which is based on differential attribution of typically human and typically animal related words. In the first experiment Polish research participant attributed significantly less human-related words and significantly more animal-related words to residents of Asia and Africa than to Europeans. In the second experiment Poles attributed less human-related words and more animal-related words to Gypsies and animals than to the other Poles. The outcomes confirm an infrahumanization hypothesis formulated by Leyens (Leyens et al., 2000; Leyens, 2009). Moreover the results of the second experiment indicate that there is no correlation between the out-group infrahumanization and in-group bias effects.
