Experiment 2 trial schematics showing example Location and Relation trials. For low load Location trials participants were instructed to imagine a line between two sample circles (shown here only for illustration purposes), hold the location of that line in memory across a delay and then decide if a test circle fell in that location or not. For high load Location trials participants maintained the locations of three circles in memory and then decided if a test circle fell in one of those locations or in a completely new location. For low load Relation trials participants maintained the vertical relationship (above/below) of two sample circles and then decided if two test circles were in the same relationship. For high load Relation trials participants maintained the three vertical relationships between three sample circles and then decided if the circles of one of those pairs were presented in the same relationship at test.
