To examine the generality of inter-species SDR performance differences previously revealed on a spatial task, four different mammalian species were tested on a brightness successive discrimination reversal task. Analysis showed that the patterns of errors yielded on the spatial task were reproduced on the brightness task, except that on the brightness task, cacomistle performance was inferior to that by squirrel monkeys. Further evidence supporting the differential extinction explanation of inter-species variation in negative transfer was also found.

There is general agreement that birds and mammals, but not fish, can display error reduction on successive discrimination reversal (SDR) tasks. Reptiles, however, show error reduction on some but not other tasks. To provide further sampling of reptilian SDR performance, two species of crocodilians, the American alligator and the American crocodile, were tested on a spatial discrimination reversal task. Both species displayed error reduction, the alligator being appreciably inferior to the crocodile.
