WebSignal detection theory (SDT) may be applied to any area of psychology in which two different types of stimuli must be discriminated. We describe several of these areas and the advantages that can be realized through the application of SDT. Three of the most popular tasks used to study discriminability are then discussed, together with the measures that … WebSignal Detection Theory 3 PG Research Methods 1. Introduction Example 1 Suppose I'm interested in knowing whether people can detect motion to the right better than to the left. I set up an experiment where faint dots move left or right at random on different trials.
