This report represents part of a thesis that was being written by Dr. Walker at the time of his death on November 30, 1965. The thesis was to have been submitted in partial fulfillment of the requirements for the PhD at Brown University; the degree was granted posthumously by Brown University in June, 1966. The present version of Dr. Walker's work was prepared from his rough manuscript and notes by Dr. Thomas J. Ryan, of Carleton University and Dr. Donald S. Blough, of Brown University. The editors accept responsibility for any flaws that may detract from this report. This work was done at Brown University, and was supported in part by USPHS grant MH-02456 to Dr. Blough.

Abstract

Pigeons pecked two response keys to move a white dot until it was equidistant from two other dots on a screen. Continuous records of dot position showed the effects of reinforcement and stimulus parameters upon the accuracy with which the dot was positioned. The method may prove useful for studying the perception of distance in non-human organisms.
