Same/different are complex abstract relations that hold between any two entities. Demonstrating understanding of these concepts requires more than discriminating identity from non-identity and more than success on match-to-sample/nonmatch-to-sample tasks. Even success on relational match-to-sample or analogical reasoning tasks may not provide sufficient evidence for understanding these concepts, because these tasks may be solvable by alternative strategies. Abstract same/different concepts were clearly demonstrated by a parrot in a task that required it to provide a simultaneous inventory of the dimensions on which arbitrary pairs of entities were both same and different.
