10.1 Goals of This Chapter

This chapter will mostly concern the use of signal detection theory to analyze data generated in psychophysical—and hypothetical neurophysiological—experiments. As usual, we will do this in MATLAB®.

10.2 Background

At its core, signal detection theory (SDT) represents a way to optimally detect a signal in purely statistical terms without an explicit link to decision processes in particular or cognitive processes in ...
