Summary
Details

""The Effect of Incentives on Accuracy of Discrimination Measured on the Galton Bar"" is a detailed scientific investigation into the relationship between motivation and sensory performance. Conducted during a formative period for experimental psychology, this work by Hughbert C. Hamilton examines whether the introduction of incentives can sharpen a subject's accuracy in psychophysical tasks. Utilizing the Galton Bar-a standard apparatus for measuring the perception of linear distance-Hamilton tests the limits of human visual discrimination under varying experimental conditions. The text explores core questions regarding the psychology of effort and the degree to which physiological thresholds can be influenced by psychological factors. By presenting empirical data and a systematic analysis of subject responses, the study offers a window into the evolution of psychometric testing and behavioral research. This work is a valuable resource for those interested in the history of science, particularly the development of experimental methods used to quantify the complexities of human perception and cognitive motivation.
