Measures of equivalence range were intercorrelated in three studies in order to determine the equivalence of the measures and constructs from which the measures were derived. In none of the studies were the intercorrelations significant. Thus, the ability to generalize from results obtained with any one measure is limited, and the meaning of the constructs of equivalence range or category width is viewed as being unclear.
