Reversal Performance

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.

Initial Peak

The performance of 5 pigeons on a successive spatial discrimination reversal task was studied over 29 reversals under conditions of non-correction. A significant reduction of errors occurred following an initial peak error score on the second reversal. Intra-problem error reduction was also significant, with errors remaining only during the initial trials of a session with continued reversal training. Terminal reversal performance approached one-trial reversal.
