smaller length calls for a smaller difference. The researcher asked the subject to assume a midpoint on 30 lines comprised of ten 2 inch lines‚ ten 4 inch line and ten 6 inch line. Then the researcher computed each mean error. The results support Weber’s law on judgment size. 2 inch lines have lesser mean error that 6 inch line. 4 inch line has greater mean error than 2 inch line. Concluding from these results‚ there is a relationship between the Weber’s law and visual perception of the subject. Introduction:
