 Three More Paradigms and Transducer Functions

Show Summary Details

This chapter continues Chapter 9's description of identification experiments by describing three more paradigms: simple detection and identification; the 2x2 paradigm; and concurrent identification. The models of Chapter 9 are used with new decision rules added for two of the additional paradigms. It discusses the effects of relaxing the assumptions (e.g., allowing correlation among analyzer outputs) and how one can measure these effects in the identification paradigm. It also discusses transducer functions and imperfect attention as they affect results of identification experiments. This and the preceding chapter are illustrated with results of experiments on the spatial-frequency dimension.

Keywords: identification experiments; multidimensional signal detection theory; detection and identification experiments; 2x2 paradigm; concurrent; attention; correlation; transducer functions
