Background of Example 2

As a second demonstration, we reanalysed the full dataset from one of our previous paper Miellet, S., He, L., Zhou, X., Lao, J. & Caldara, R. (2012). When East meets West: gaze-contingent Blindspots abolish cultural diversity in eye movements for faces.

Previous studies testing Western Caucasian (WC) and East Asian (EA) observers showed that people deploy different eye movement strategy during free-viewing of faces. Western Caucasian observers fixate systematicly towards the eyes and mouth, following a triangular pattern, whereas East Asian observers perfominatly fixated at the center of the face (Blais, Jack, Scheepers, Fiset, & Caldara, 2008; Caldara, Zhou, & Miellet, 2010). Moreover, human observers can flexibly adjust their eye movment strategy to adapt to the environmental constraints, as shown using different gaze-contingent paradigm (Caldara, Zhou, & Miellet, 2010; Miellet, He, Zhou, Lao, & Caldara, 2012). In our 2012 study, we tested two groups of observers in a face task where their foveal vision were restricted by a blindspot. This is a mixed design with the culture of the observers as the between-subject factor (WCs or EAs) and the blindspot size as the within-subject factor (four level: natural viewing, 2° blindspot, 5° blindspot, or 8° blindspot).
