In our version of the relational matching task, each condition involved a yes/no judgment based on a stimulus array including four shapes with varying textures. On Shape trials, participants indicated whether there was at least one shape match present in any of the stimuli pairs. On Texture trials, participants indicated whether there was at least one texture match present in any of the stimuli pairs. On Dimension trials, participants indicated whether the stimuli in the bottom pair matched along the same dimension as the stimuli in the top pair. Shape and Texture trials required low-level relational processing, whereas Dimension trials required relational integration.
