Show Summary Details


This chapter describes identification experiments where an observer is asked to identify which of several nonblank stimuli has been presented. Only identification experiments using stimulus intensities so low that the stimuli themselves are imperfectly discriminable from a blank stimulus are considered, because these near-threshold experiments are particularly suited for studying multiple visual pattern analyzers as discussed in Chapter 1. This chapter presents classification experiments (identification experiments in which there is a one-to-one correspondence between the responses and stimuli) and three different kinds of discrimination experiments (identification with only two stimuli). The appropriate multidimensional signal detection models for interpreting their results are presented as developments of the models in preceding chapters.

Keywords: identification experiments; classification experiments; discrimination experiments; multidimensional signal detection theory; vectors
