A nonparametric technique for assessing the effects of response bias within the Signal Detection Theory paradigm was developed. The technique involves modification of the 2 × n table produced when rating scale data are collected under the SDT paradigm. A χ2 value computed from the modified table is used as the unit of analysis in statistical analyses. This new measure of response bias has been shown to be independent of several nonparamentric measures of sensitivity when tested under three different experimental designs.
