It has been proposed that East Asian and Western Caucasian observers employ different eye-movement strategies during face identification, with Asians preferring to fixate towards the face centre (Blais et al., 2008, PLOS ONE). Here, we evaluated whether Asian and Caucasian observers differed in the location of task-critical first eye movements during a fast face-identification task. Using a foveated ideal observer (Peterson & Eckstein, 2012, PNAS), we assessed whether the pattern of behaviour can be explained by an interaction between the race-specific distribution of discriminatory information in faces and the varying spatial resolution across the visual field.
Methods
Asian and Caucasian observers (16 each) participated in two experiments: one, identifying Asian faces among other Asian faces; another, identifying Caucasian faces among other Caucasian faces. In each condition, observers viewed and …
