Stimuli
Images of 600 people were used. Half were male. The images were collected from the social-networking website Facebook.com. Images were selected from people who were members of groups associated with further and higher education bodies either in the UK (for White faces), sub-Saharan Africa (for Black faces) and East Asia (for Asian faces). These images were collected by a naive research assistant who selected images according to a set of criteria: Images had to show a clear view of a single person that was of sufficient quality such that it would be recognisable by a friend. If the face in the image had a weird expression or was possibly of a race other than the main race for the region then it was rejected. The face was also rejected if the person depicted looked to be under 18 or over 30 years old.
