Stability of line-length estimates using the method of absolute magnitude estimation

Abstract

Absolute magnitude estimates of line length were made by two groups of nine subjects each. One group was tested and then retested at an intersession interval of 1 year and the other, at an intersession interval of 2 years. High temporal stability was observed in both groups in both the slope values, individual and group, of the power functions and in the numerical responses themselves. © 1983 Psychonomic Society, Inc.
