In Experiment 1, 18 cross-bred fowls were run on standard closed field test problems and their performance compared with that of rats, cats, possums and ferrets. The fowls exhibited learning rates similar to those of possums and lower than those of rats, cats and ferrets, but contrary to prediction they showed little use of available visual cues. In Experiment 2, 12 cross-bred fowls were run through the same problems but this time the walls of the maze problems were painted black instead of white while the maze pathway remained white. While their learning rates remained unchanged, the fowls made fewer errors in the high contrast maze and gave evidence of using visual cues in a manner similar to cats. The two experiments demonstrate the value of what Bitterman (1965) calls “control by equation” for interspecies comparison, i.e. of using proportional rather than absolute measures of performance in describing and interpreting the performance of different species on learning tasks.
