Regression interpretation of differences in time-intensity trading ratios obtained in studies of laterality using the method of adjustment

This paper proposes a regression interpretation of the laterality matching data recently reported by Young and Levine [J. Acoust. Soc. Am. 61, 607-609 (1977)]. Under this interpretation, the difference between the trading function obtained when delta t is adjusted and that when delta I is ascribed to a judgmental bias associated with the method of adjustment. Arguments against associating the results of Young and Levine with the issue of dual images are presented.
