 In this script, we are working through a large number of different contrasts for the same data. The purpose is to introduce both the preprogrammed (“canned”) and the general options to specify hypotheses about main effects and interactions.

 There are a couple of differences between the first and this follow-up experiment, rendering it more a conceptual than a direct replication. First, the original experiment was carried out at Peking University and this follow-up at Potsdam University. Second, diagonal orientations of rectangles and large target sizes were not part of the design of @Kliegl2011.
